Description

The invention relates to a portable, battery-operated computer device. In particular, the portable computing device may be attached to a human head and then worn, for example, like glasses. Such a portable computer device is also known as data glasses, head-mounted display or head-up display.

A portable computing device according to the present invention may include a central processing unit (CPU), a random access memory (RAM), a microphone, a digital camera, a speaker, a wireless signal transmission antenna using, for example, Bluetooth or WLAN, an acceleration sensor, a tilt sensor, means for Location determination, for example, comprising a GPS antenna, a battery and an interface such as a REST interface in order to communicate with other devices can.

Data glasses can be used, for example, for visual process control in process and warehouse logistics. This means that the user, e.g. a worker in a logistics warehouse or a chemist when mixing a recipe, often goes through specific steps in a process sequentially to which context-dependent information, instructions or even warnings are displayed on the data glasses.

In many cases it is helpful to have both hands at leisure. For safety reasons, this may even be necessary in the above examples from logistics or chemistry.

Using the example of warehouse logistics, the procedure is clearly visible in detail: In principle, goods are transported from A to B, for example, a product for an order from a storage rack to a truck. For example, the warehouse worker can verify the location of the removal and / or the product by scanning a barcode. The barcode is then available locally or on the product.

To scan a barcode, the camera must be activated on the data glasses. For reasons of data protection law, switching off a camera in the event of improper use may be necessary.

A user or user, for example a warehouse worker, can activate a camera, ie switch it on to carry out a scan. If the camera is active, a barcode can be searched in the livestream of the camera and, if available, decoded by a data processing program and further processed. Then the data processing program can deactivate the camera again or the camera switches off automatically after a predetermined time interval of, for example, 3-5 seconds.

The activation of the camera, or generally speaking, the activation of a process step (in the example mentioned a verification of the product or location by Barcodescan) typically takes place so far by a manual action on an operating device or the data glasses. The user taps on a device or presses a button.

This activation counteracts the need to have both hands free. In the above example, the warehouse worker usually has the product to pick in hand if he wants to start the verification scan.

It is known in portable computers to activate an action by a spoken command. The problem with this solution may be an existing typical noise level in a warehouse. Unintentional activation by a colleague who also works with speech can be the result. Constant speech is also disadvantageously associated with fatigue.

From the publication DE 10 2012 100 354 A1 It is known to detect position changes using acceleration sensors or using a mobile camera as part of picking processes in warehouses. The use of data glasses during picking operations is out of the EP 2 161 219 A1 known. The US 2012/0235902 A1 discloses a head mounted information system with motion sensors. A head-mounted computing device, where a user can, for example, activate a display by means of movements, goes out of the US 2016/018872 A1 out.

It is an object of the invention to further develop the aforementioned prior art. In particular, it should be possible to activate a process step in a portable, battery-powered computer device, without having to use a hand.

The object of the invention is achieved by a method having the features of claim 1 and by a data glasses with the features of the independent claim. Advantageous embodiments emerge from the subclaims.

The object of the invention is achieved by a method for loading an article onto a transport vehicle by a user of data glasses. For example, the user wears the data glasses or parts thereof in a similar way Glasses or a headgear. The article is stored at a destination on a shelf. The data glasses comprise a camera and a motion detection device for a motion-dependent activation of a process step:

The user first moves from a source to a destination. If the user reaches his destination, a process step is activated depending on one or more movements of the user. After activation, a process step for loading the article onto the trolley is performed.

The user can thus perform desired actions or operations for loading the article onto the trolley without having to use hands for activating a process step.

The activation of the process step comprises, in particular, switching on the camera. Subsequently, an associated process step can be carried out, for example, a barcode can be scanned. By scanning the barcode, for example, a location or an item can be verified or identified. A barcode means a machine-readable code that represents data. For example, the data provides information about a location or about an item. It can thus be ensured that the relevant object is loaded.

After scanning the barcode, the camera is preferably switched off automatically in order to fulfill, for example, data-regulatory requirements.

It is basically possible to activate the process step or the camera by keeping the data glasses stationary. The data glasses are held steady when it is no longer or only very slightly moved.

Alternatively or additionally, the camera is turned on in one embodiment by detecting a movement pattern. Activation can thus be accelerated.

The user preferably receives work instructions on the data glasses in order to further optimize work steps and to ensure trouble-free operation.

A user can thus finally remove the desired item from a shelf and park it on an entrained transport vehicle. By the trolley then the object can be transported in the intended manner on.

To solve the problem, data goggles comprise a central processor, a data memory, a camera and a motion detection device for activating the camera for carrying out a process step.

"Data glasses" means a portable, battery powered computer device having a camera, at least a portion of which is dedicated and adapted to be attached to a human head and thus worn. In general, a data glasses in this sense can be worn at least in part as a pair of glasses. The computer device can therefore be designed like a pair of glasses. But it is also possible that the computer device is designed in part as a pair of glasses and also includes a different shaped component, which is connected to the "glasses" via a cable. The differently shaped component can then be carried for example in a pocket of a garment and serve, for example, the operation and / or the power supply. However, the differently shaped component may alternatively or additionally comprise, for example, the data memory and / or a CPU.

The part which is intended and suitable for being attached to the head and thus worn basically comprises a camera and / or a display. By moving your head, the camera can be aimed at a desired object without having to use hands. A display is present so that a user can see about this written or pictorial information when the data glasses are properly attached to his head.

"Data storage" means an electronic storage medium with which data can be stored. "Camera" means a photographic equipment that can record static or moving images and / or transmit via an interface. "Motion detection device for activating the camera for carrying out a process step" means a device that recognizes automatically by motion detection as soon as a process step is to be performed, and which activates a process step following such detection and in particular activates a camera of the data glasses. Thus, a user does not have to use their hands to activate a process step, for example to turn on the camera, so that the camera can record static or moving images and / or transmit them via an interface.

It is sufficient in a technically particularly simple embodiment that the data glasses for a predetermined period of time is not moved to activate the camera. Following this can using the camera, for example, to scan a desired barcode.

If the intended process step has ended, the associated application which has been activated beforehand is deactivated in principle. It can be disabled for a hardware component or a computer program. For example, if a camera has been activated, the camera automatically shuts off after a successful recognition of the barcode.

If no intended process step is carried out within a predetermined time interval of basically a few seconds, the corresponding application is also fundamentally deactivated. If, for example, after switching on a camera, no barcode is scanned as intended within a preset time interval, the camera preferably switches off automatically again.

In one embodiment, the motion detection device for activating a process step such as activating a camera comprises one or more sensors with which a movement pattern of the data glasses can be determined. The motion detection device for activating the camera optionally comprises a comparison device which compares a movement pattern of the data glasses determined by the one or more sensors with a stored movement pattern. Alternatively or additionally, the motion detection device for activating the camera is set up so that it can transmit a determined movement pattern to an external comparison device wirelessly, for example by WLAN, DECT or Bluetooth, and wirelessly from this external comparison device the result of a comparison carried out between the detected movement pattern and an existing movement pattern can receive. The motion detection device for activating the camera further comprises a switch-on device, which can activate the camera depending on the result of the comparison.

"Movement pattern" means a sequence of at least two different movements of the data glasses, which differ by directions of movement and / or movement speeds and / or time duration and / or accelerations and / or position. A movement pattern can thus be formed by a first movement of the data glasses in a first direction of movement and an adjoining second movement of the data glasses in a different second direction of movement. The movement pattern may alternatively or additionally be formed by different movement speeds of movements of the data glasses. The movement pattern may alternatively or additionally be formed by different accelerations of movements of the data glasses. The movement pattern may alternatively or additionally be formed by different tilting movements of the data glasses. The movement pattern may alternatively or additionally be formed by a different time duration (ie time periods or time intervals) of movements of the data glasses. The movement pattern can be formed from different properties of the aforementioned movement possibilities, that is to say for example initially comprise a movement direction and subsequently an inclination movement or an acceleration of a movement. The movement pattern may include more than two different movements of the data glasses. The movement pattern may include that the data glasses are not or only slightly moved after a movement for a preset time interval. The movement pattern may include that the data glasses are initially not or only slightly moved, and then significantly stronger and or in a predefined manner.

The data glasses comprise one or more sensors, such as an acceleration sensor, position sensor, vibration sensor or tilt sensor, which are suitable for determining one or more of the aforementioned movements.

"Comparator" means a device that compares a detected motion pattern of the data glasses with an existing motion pattern. The comparison device can thus obtain a determined movement pattern and a stored movement pattern, which compare the two movement patterns with each other and provide a result of the comparison. External comparator means that the comparator is physically separate from the data glasses. The provision of an external comparison device is particularly advantageous if a larger amount of computation is to be operated for the performance of comparisons or must. The technical requirements and the energy requirements can then be kept low in the data glasses advantageous yet.

The comparison establishes a degree of agreement between a detected motion and an existing motion. The switch-on activated in the example mentioned the camera depending on the detected degree of agreement. Basically, there is a predetermined threshold. If the degree of coincidence exceeds the threshold value, then the switch-on device switches on the camera. The same applies to an activation of another process step.

By using a motion pattern, rather than just a single motion, to automatically power on the camera, for example, workflows can be speeded up. For example, when a user approaches his destination to remove an article from a shelf, the camera can be activated very quickly by detecting a movement pattern. If the user has reached his destination, ie the destination, he has, for example, no or little extra time to invest in order to perform a predetermined movement for activation of the camera. Activation does not require the use of hands. A predetermined movement also includes the case that the data glasses must be kept still to activate the camera.

The existing movement pattern is stored in one embodiment of the invention in the data memory of the data glasses. This embodiment is particularly suitable for a simple movement pattern, which is composed for example of only two different movements. If a single movement such as, for example, keeping the data glasses stationary for a predetermined period of time is sufficient, this movement is also advantageously stored in the data memory of the data glasses in order to minimize the technical outlay.

The existing movement pattern is stored in an embodiment of the invention in an external data memory. External data storage means a data storage that is physically separate from the data glasses. The external data memory may be part of the aforementioned external comparison device. If necessary, the movement pattern stored in the external data memory is transmitted wirelessly to the data glasses in this embodiment. This embodiment is particularly suitable when a movement pattern depends on a situation and therefore many different movement patterns are to be managed. This embodiment is also advantageous when a plurality of data glasses are used, which can then centrally access the one external data memory and movement patterns stored therein. Movement patterns do not have to be set up individually for each data goggle, which keeps the administrative effort low.

If, for example, a user is at a starting point A and wants to move to a destination B, then there is a situation in the aforementioned sense. The movement pattern can now be formed by the movements or parts thereof required for it, which the user must make together with the data glasses in order to get from the starting point A to the destination B. Thus, the movement pattern depends on where the starting point and destination are located. For such a case, it may be favorable to obtain a movement pattern from an external data memory provided in order to be able to keep the technical requirements and the energy requirements for the data glasses particularly low and / or to keep the administrative effort low.

If the user has reached the destination B, a process step is activated by recognizing an existing movement pattern. Following this, the location B may be the new starting point to move to a next destination C. There is then another motion pattern to reach the destination C. The smart glasses can then wirelessly receive a new movement pattern characterized by movements required to move from the new starting point B to the next destination point C.

Advantageously, the camera can be activated by more than one movement pattern or by more than one movement. The same always applies to the activation of another process step. If, for example, a movement pattern has been detected incorrectly, the camera can nevertheless be activated by an alternative movement pattern. If, for example, a user moves from a starting point A to a destination B and if the necessary movements are used to automatically activate the camera when the destination is reached, it is only possible with considerable expenditure of time to execute the associated movements again to the camera to reactivate in case of a faulty motion detection. In this case, it can then be activated using another movement pattern or another movement.

Basically, it is always envisaged that the camera can be activated by a sufficiently long silence or silence. The data glasses are then not or only very slightly moved. To scan a barcode, the camera must be kept still. This natural process is exploited in this embodiment, in order to be able to reliably activate the camera then, without having to use hands, if previously could not be activated by another movement or a movement pattern due to a disturbance.

In one embodiment, keeping still or resting can be the last movement of a movement pattern so as to be able to keep the time required for a stand-still for activation of the camera to be particularly low. Thus, a motion pattern may include one pace motion and one second silence to activate the camera. If a user moves on Pace to a destination, he will need to keep the camera quiet for scanning at the destination. If it has been recognized that the data glasses have previously been moved at walking speed, preferably at least for a certain minimum period of time, a relatively brief standstill may be sufficient to activate the camera. Nevertheless, if the camera has not been activated because the movement at walking pace has not been identified correctly, the data glasses in an advantageous embodiment then have to be held still for two seconds, for example, in order to activate the camera. In this embodiment, the camera thus turns on after a standstill of, for example, two seconds always on. If a movement has been previously detected with walking speed, then the camera switches on already after, for example, one second in order to be able to keep the time for a tiring silencing as short as possible.

In one embodiment of the invention, the data glasses are set up so that they receive wireless user information and can transmit the received user information to the user. By "user information" is meant information for the user of a data goggle, which the user requires to carry out a process step or which supports the user in the execution of a process step. Such user information may include which destination a user should move to. Such user information may include security provisions. Such user information may include tasks, such as the task of picking up an item at a designated destination and transporting it to another location.

Submitting user information to the user means presenting it to the user so that the user can read or hear it. In particular, this embodiment is suitable for selecting an associated movement pattern together with user information and for comparison by a comparison device. User information basically tells what a user should do. Since a user usually has to perform movements in response thereto, it is advantageous to simultaneously select an associated movement pattern and provide it for comparison by a comparison device. An apparatus capable of performing these tasks is an external server (computer) which may include an aforementioned external comparator. The external server is physically separate from the data glasses and can communicate wirelessly with the data glasses.

In one embodiment of the invention, depending on a first scanned barcode, the camera is either not switched off again immediately or not within a few seconds, or it is reactivated within a predetermined time interval. For example, if a user has reached his destination, in one embodiment he scans a barcode that characterizes his destination. In this way, it can be verified that the user has reached the correct destination. The user can now receive information, for example via the data glasses, that he has reached the correct destination. Typically, a user will now want or need to scan a next barcode from an item. The predictability of the need for a next scan is exploited in this embodiment, either to turn off the camera again immediately after detection of the first bar code again or turn on the camera in a timely manner again. Even so, it can be avoided that a user has to keep data glasses excessively tedious in order to scan a next barcode.

Basically, regardless of other activation options, a camera can always be activated manually, ie with the help of one hand, in order to be able to manually activate it if necessary (for example due to an accident). The same applies to activating another process step.

In one embodiment of the invention, the data glasses are used to record movement patterns and to create an existing movement pattern for the activation of the camera or another process step from recorded movement patterns. The movement pattern thus created serves as a reference and is available in this sense. Also in this embodiment, it is advantageous to always be able to activate the camera manually. In the case of recurrent work processes, the data glasses are initially also used to determine the associated recurring movement patterns. After the determination of such recurring movement patterns, these are stored in such a way that they can serve as "existing movement patterns", ie reference movement patterns.

Instead of data glasses, it is also possible to use another portable computer device which, for example, can be wholly or partially attached to a human arm. However, data goggles are preferable because viewing directions can be exploited and a user can then obtain visual and / or acoustic information about the portable computer device in a particularly simple and reliable manner.

Preferably, the data glasses are also designed as a cap or helmet and can then like a cap or a helmet are worn. The data glasses can thus fulfill an added benefit and, for example, warm or protect the human head of a user.

The invention also relates to a system comprising data glasses, wherein data glasses and servers are set up so that they can exchange information wirelessly.

Preferably, the server is set up so that it transmits work instructions to the data glasses during operation. For example, a user may receive visually and / or audibly information about a destination or an item to pick up at a destination.

Preferably, the data glasses are set up so that during operation it transmits information to the server which has received the data glasses as a result of scanning a barcode. This allows a location and / or an item to be verified by the server. Following this, the server can transmit the result of the verification to the data glasses. The result can then be transmitted visually or acoustically to the user through the data glasses.

In an embodiment, movement patterns for the activation of a process step are stored on the server in order to keep the administrative effort low.

The invention can be used for example for the storage of objects. Then, a user brings goods from a departure point to a destination to sort the goods at the destination, for example, on a shelf. Also in the context of a storage barcodes can be scanned according to the invention at the objects and / or at the destination, for example, for the purpose of verification.

The invention can be applied as part of an inventory. As part of an inventory barcodes can be scanned according to the invention.

Work instructions transmitted to the data glasses may receive information for packaging and / or sorting items. Thus, a trolley may comprise a plurality of compartments or packages. The work instructions can contain information about which items should be sorted into which subjects or which packages. The sorting in turn can be supported by means of barcodes. For example, packages or compartments may include barcodes that are scanned for verification, for example. Even in such cases, it is advantageous to scan according to the invention, ie first to switch on and then scan a camera of data glasses by one or more movements.

In one embodiment of the invention, movements or movement patterns are person-dependent or user-dependent. Each person, ie each user, is then assigned at least one own movement or movement pattern. A movement pattern can thus incorporate movement speeds and typical movements as a function of persons in order to be able to reliably and quickly activate a process step in an improved manner. In particular, a user-dependent keeping calm of a pair of data glasses is included, since people are able to hold a pair of data glasses in different positions. Such user-dependent movements or movement patterns are first determined by means of smart glasses and stored. After storage, these serve as existing movements or existing movement patterns, ie for reference purposes.

The data glasses preferably comprise a user recognition device. The user recognition device recognizes the user in order to evaluate person-dependent movement patterns as a function of the recognized person or to have them evaluated by a server. The user recognition device may comprise one or more sensors in order to be able to recognize a person based on biometric features such as voice, eye or fingerprint. In a simple embodiment, there is an input device through which the user can identify himself to the data glasses.

Preferably, there are at least two different motion sensors in order to be able to reliably determine the silence of a data goggle in a reliable and trouble-free manner. A first sensor is in particular a linear acceleration sensor (preferably adjusted for the gravitational attraction). A second sensor is preferably a gyroscope for detecting changes in position. In particular, it is possible to determine movements in all three spatial directions by the sensors.

Movements as well as movement patterns can not only include walking or resting, but also, for example, stooping, grasping, straightening or getting up. For example, in the course of bending over, grasping and then straightening up, a significant acceleration first of all occurs downwards for a short period of time. This is followed by a period of time with non-relevant sensor values that may be caused by searching and gripping an object. Because of a following uprighting, there is an upward acceleration similar in magnitude to stooping. A corresponding existing movement pattern may advantageously have been advantageously created person-dependent, since just such movements are performed differently depending on the person and at different speeds.

The invention may also be used in the context of production control and retrofitting of machinery. Workflows can be supported to avoid malfunctions and accidents. Again, a user may receive work instructions and safety regulations about the data glasses. The data glasses enable process steps to be activated. It may be possible, for example, to activate a camera so that it forwards the recordings from production to a server for checking and checking purposes. If required, external goggles and devices can be activated by the data goggles according to the invention. Through data goggles, work steps can be recorded and documented in order to make them comprehensible and verifiable. Again, for such purposes, it may be advantageous to be able to activate a camera as needed to record work steps. Being able to activate a camera according to the invention can be advantageous in order to enable remote maintenance.

The invention can be applied not only to a picking of goods, warehousing or machinery, but also to other fields such as chemical fields or to the field of pharmacy. Thus, a user may be assisted by the invention in the preparation of a chemical or pharmaceutical formulation.

In accordance with the invention, machines and apparatus can also be activated, such as a balance, to weigh constituents of a formulation. In this context too, it is of great advantage not to need hands for activation in order to be able to concentrate on the process of weighing in, which may be particularly important in the case of toxic substances.

• 1: Datenbrille
• 2: Warenlager

The invention will be explained in more detail below with reference to a non-limiting exemplary embodiment by means of figures. Show it:

• 1 : Data glasses
• 2 : Warehouse

The 1 shows a data glasses 1 by a user 2 similar to how glasses are worn. The data glasses 1 includes a transparent display 3 as well as a camera 4 , Through the display 3 Through it the user can see his surroundings. On the other hand, the user can 2 Read information through the display 3 through the data glasses 1 being represented. Using the camera 4 For example, the user can scan a barcode visible to him at the same time. The data glasses can include a speaker five, allowing the user 2 also acoustic information from the data glasses 1 can receive.

The 2 shows a warehouse with a plurality of shelves 6 in which goods are stored. The user 2 the data glasses 1 is located at the starting point A. About his data glasses 1 he receives the information that he should run to the destination B To reach the destination B, the user becomes 2 at walking pace along the path 7 initially along a first section in a first direction. After passing the first section within a first period, the user must 2 Turn right at a right angle to go through a second section in a second direction. This second section of the path becomes the user 2 then go through in a slightly shorter time compared to the first period, because this second section is slightly shorter than the first section. After passing the second section the user must 2 turn right at a right angle again to move in the first direction. The user only has to go through this third section of the path very briefly, since this third section is only very short.

1. a) Bewegen der Datenbrille mit Schrittgeschwindigkeit in einer ersten Bewegungsrichtung für einen ersten Zeitraum.
2. b) Ein sich daran anschließendes Bewegen der Datenbrille mit Schrittgeschwindigkeit in einer zweiten Bewegungsrichtung für einen zweiten Zeitraum, der kürzer als der erste Zeitraum ist.
3. c) Ein sich daran anschließendes Bewegen der Datenbrille mit Schrittgeschwindigkeit in der ersten Bewegungsrichtung für einen dritten Zeitraum, der kürzer als der zweite Zeitraum ist.

An existing first movement pattern for moving from the starting point A to the destination B may then be as follows:

1. a) Move the data glasses at walking speed in a first direction of movement for a first period.
2. b) An adjoining movement of the data glasses at walking speed in a second direction of movement for a second period, which is shorter than the first period.
3. c) A subsequent movement of the data glasses at walking speed in the first direction of movement for a third period, which is shorter than the second period.

To avoid mistakes, the data glasses can 1 the user 2 visually and / or acoustically provide information that he has the path 7 along to reach starting from the starting point A to the destination B.

Moves the user 2 along the path 7 , so can his through the motion detection device of the data glasses 1 recognized Movements are continuously compared with this existing first movement pattern to already with the arrival of the destination B, the camera using the Einschalteinrichtung the data glasses 1 quasi delay-free switch as soon as a sufficiently high agreement has been determined by a comparison device with the existing first movement pattern. The user can then immediately scan a barcode that verifies that he has reached the correct destination B. Alternatively, however, the movement pattern may be used to verify that the destination B has been reached. In this case, the movement pattern is not only used to perform the process step "activate camera" without having to use hands, but also the implementation of the process step "verification of the destination or destination B". In this case, the user can skip verification by scanning a designated barcode and immediately scan a barcode present on the item or item. This way can be done by the user 2 be verified immediately that the applicable product has been identified. Has the user 2 the required amount of goods or items from the shelf 6 taken at the destination B and loaded on the entrained dolly or parked, he receives from the data glasses information that he should now go to the new destination C and that along the path 8th ,

1. a) Bewegen der Datenbrille mit Schrittgeschwindigkeit entgegengesetzt zur ersten Bewegungsrichtung für einen ersten kurzen Zeitraum.
2. b) Ein sich daran anschließendes Bewegen der Datenbrille mit Schrittgeschwindigkeit in der zweiten Bewegungsrichtung für einen etwas längeren zweiten Zeitraum.
3. c) Ein sich daran anschließendes Bewegen der Datenbrille mit Schrittgeschwindigkeit in der ersten Bewegungsrichtung für einen dritten Zeitraum, der dem ersten kurzen Zeitraum entspricht.

The path 8th comprises a first relatively short section in the opposite direction to the aforementioned first direction of movement. The path 8th further comprises a second slightly longer portion in the aforementioned second direction of movement. The path 8th finally includes a third section in the first direction of movement, which in turn is relatively short. An existing second movement pattern may be as follows:

1. a) moving the data glasses with walking speed opposite to the first direction of movement for a first short period of time.
2. b) An adjoining movement of the data glasses with walking speed in the second direction of movement for a slightly longer second period.
3. c) An adjoining movement of the data goggles at walking speed in the first direction of movement for a third period corresponding to the first short period.

Has the user 2 reached the destination C, the existing second movement pattern can in turn be used in the same way to both verify that the destination C has been reached, as well as to activate the camera to immediately scan a barcode that can be at a on the shelf 6 stored goods is appropriate. The user 2 is preferably displayed in this case on the data glasses or acoustically informed that the user 2 has reached the destination C and he can scan the bar code attached to the goods.

If the verification failed, the user can 2 by keeping the data glasses quiet 1 activate the camera to scan a bar code characterizing the destination C. Afterwards he can continue in the usual way.

Since the first and the second movement pattern depends on the respective starting location and is therefore situation-dependent, the first and second movement patterns are preferably not stored in the data memory of the data glasses, but in a dedicated memory of a server. The computing effort to be operated by the data glasses is kept as low as it can be sufficient, for example, the respective movement patterns to the data glasses 1 wirelessly as soon as it is needed. A comparison device of the data glasses 1 can then make a comparison with the last transmitted motion pattern. Alternatively, the server may be out of the data glasses 1 get the movements that are detected by the data glasses. The server can then make a comparison between the transmitted movements and the associated movement pattern by means of its own comparison unit and, if the agreement is sufficiently high, the result to the data glasses 1 transfer.
