Introduction of optical sensing device applied in electronic equipment.

 Constructive Equipment Concept

 In most cases the devices are arranged with an upright foreground image, with a single screen, further integrating components such as a slanted table whose surface is defined by a touch screen (or multi-touch) It has embedded transduction technology, featuring various software and accessories, such as a keyboard design, and may also have wireless communication devices for example.

 As for transduction technology there is a great diversity of physical principles being used, it is possible to highlight transparent electric conductive blades with touch detection through variation of electric resistance, capacitance and field forces, ultrasonic transducers applied to blades of glass or light beams tangent to the surface.

However, sensing systems that make use of optical principles to recognize pressure points on the face of a translucent surface where this contact generates a reaction due to a physical phenomenon, interfering with the internal reflection of visible light and highlighting, are noteworthy. infrared, generating light spots corresponding to the touch area (s), which can be detected by the camcorder sensitive to visible and infrared light, positioned in front of the other surface face. Ultimately, suitable software processes real-time generated video frames, identifying the coordinates of the point (s) touched, and passing them on to applications that can then use the "" screen surface. multi-touch "as an input device.

State of the art for transduction technology.

 Among the touch screen devices currently on the market, many use optical principles for pressure point recognition, particularly those consisting of simultaneous multi-touch sensitive surfaces, commonly referred to as "multi-touch" devices, where they are in their entirety. Most are based on the principle of frustrated Total Internal Reflection (FTIR), in which a translucent material plate is used as an optical guide for visible and infrared light and a camcorder is used to capture a sequence. images of said surface.

 Already the functional concept can be translated and understood by applying a compressive force on the surface of the surface that is pressed (by touch of one or more users, for example); This contact generates a reaction due to a physical phenomenon, interfering with the internal reflection of visible and infrared light, generating light spots corresponding to the touch area (s), which in turn can be detected by the sensitive camcorder. visible and infrared light positioned opposite the other surface face. Lastly, suitable software processes the generated video frames in real time, identifying the coordinates of the point (s) touched, and passing them to applications that can then use the screen surface. "multi-touch" type as an input device.

Critical analysis of optical sensing solutions.

Multi-touch surfaces are currently available on the market in the form of difficult tables or interactive panels. portability. The height of the tables (in the case of horizontal surfaces) and the depth of the panels (in the case of vertical surfaces) is typically about half of the diagonal dimension of the surface. For example, for a 60-inch diagonal multi-touch device, the device thickness is about 30 inches, or 75 cm. In the case of panels, it is possible to achieve a false impression of surface fineness by embedding it in a wall or partition, but the difficulty of handling and transportation due to the actual dimensions of the device remains. It is concluded that the current sensing devices with optical principle present constructivity that imposes large size, limiting their use only in locations with large area and also makes it impossible to introduce portability to electronic equipment with embedded multi-touch technology. . Causes of equipment size limitation.

 Too thick the devices

Multi-touch is explained by the need to position the camera far enough away from the touch screen so that the image covers the entire surface. However even with the use of wide angle lenses, this distance, as stated above, is equal to about half the diagonal dimension of the surface. The aperture angle of the lens that can be used is limited by the introduction of distortions in the image, with consequent loss of resolution, which compromises the performance of the device.

 TECHNICAL STATE ANALYSIS

 Finally, by studying in depth this condition of limitation it is possible to arrive at a logical conclusion that such limitation, in terms of the considerable size of the optical sensing modules, lies in the fact that from a conceptual point of view, the images generated under the screen ("touch screen" or "multi-touch") shall be

 i

acquired directly by the camera, which in turn imposes a This camera's long-distance specification relative to the screen, which converges to obtain a highly volume-sensing sensing module.

 In-depth analysis of known equipment provided with an optical sensing module, as described in the previous paragraph, leads to a reflection on the physical constraint, or in other words, the exceptional size of this type of equipment when properly assembled, where it is This size converges by generating limitations on its portability and, consequently, restricting its field of application.

 GOALS AND ADVANTAGES

 Given the above and based on the analysis of the state of the art, the applicant devised an unprecedented electronic equipment with compact optical sensing module and projection module articulated with each other and applied in electronic equipment shipped with surface pressure sensitive screens, where one of the The purpose of this request is that the "electronic equipment" operated by one or several users be provided with an integrated system of interactive devices, whose development paradigm was based on achieving excellence and functional reliability for this type of equipment, solving, in particular, the portability problem, a problem revealed in the numerous solutions anticipated by the state of the art.

Another objective achieved by the present instrument is that the compact optical sensing module presents with constructivity that should converge to the reduction of the depth dimension of the camera-surface assembly (especially when considering the technology in "multi-device"). touch "), for a given diagonal surface dimension, of less value than that already practiced in related solutions known in the prior art, where this condition is made possible by the introduction of a convex mirrored surface with a particularly projected, as well as the repositioning of the image capture camera, which is now placed on the rear end of the touch screen and / or multi-touch screen.

 This time the logical principle embedded in the new optical capture sensing technology based on the touch screen or camera / mirror set can be translated into the indirect way the screen surface image is acquired by the camera, that is, the surface image is acquired indirectly through the mirror surface reflection.

 Thus is established the technological and constructive paradigm that converged on latent advantages, among which it is pertinent to explain:

 - it is a simple solution where the introduction of the additional component of one or more mirrors is compensated by the dimensional reduction of the equipment;

 - the electronic equipment having the unprecedented onboard sensing module, gives unprecedented portability;

 - Portability conferred by the new sensing module confers greater differentiated commercial value as it ensures wide penetration into niche markets eager for compact and portable solutions, both interactive device cell-type equipment designed for single or simultaneous use by multiple users;

 - As a consequence of the previous items, the consequent large-scale production converges to a reduced industrial cost when compared to solutions already anticipated by the state of the art;

 - The unprecedented concept of optical nature sensing in indirect image capture can be applied to all kinds of optical principle transduction technology;

- the unprecedented compact sensing module brings in its core ergonomic, handling and transport features.

BRIEF DESCRIPTION OF THE INVENTION.

 To achieve these goals, electronic equipment was idealized based on a constructive concept formed by a set of devices and functional modules, namely:

 1. Device opening / closing device;

 2. Functional image projection module;

 3. Optical sensing module;

 4. Information issuing device; and

 5. Control module and information processing.

 In particular, the optical sensing module and the opening / closing device of the equipment are differentiating aspects that give the new equipment the requirements of novelty, inventive activity and industrial application, where in particular the sensing module is decisive in the physical reduction of the equipment. The volume of the equipment, while the opening / closing device of the equipment allows an optimization of this volume when it is not in use, thus ensuring its portability and ergonomics of transport.

The said optical sensing module is provided with unprecedented technology, which is based on an odd arrangement of the "screen, one or more differentiated mirrors and camera" components, where this camera is positioned at the rear end of the screen component, which, in turn. Instead, it may be in a linear or inclined position relative to the rest and support surface of the equipment, and immediately below this screen is defined one or more special mirrors, which have a flat surface in its frontal area that migrates linearly to an area convex near its extreme posterior portion. Thus the minimum distance between screen and one or more mirrors ensures the mounting of a compact sensing module, without prejudice to the quality of images captured by the camera. The integrated system of interactive devices stands out for the application of the unprecedented optical sensing module that innovates by presenting compact dimensions, the result of an unprecedented physical arrangement of its main components (screen + one or more special mirrors + camera), giving the equipment the inventive activity requirement, since electronic equipment of this nature, known from the state of the art, has a large common feature.

 Another condition of innovation, still within the scope of a compact solution, lies in the odd constructivity of the set of interactive and or structural devices that make up the equipment now claimed, these provided with an unprecedented articulation mechanism.

 In addition, it is pertinent to note that although the sensing module is compact, it does not compromise the final quality of operation of the "touch screen" or "multi-touch" screen, as its operational area is reduced without, however compromise the operating ergonomics of the table of which it is part.

 Thus it is conclusive that the equipment provided with integrated interaction devices innovates by presenting constructiveness that confers technical, ergonomic and economic advantages, and in addition such constructive novelty is provided with inventive activity, since such constructive concept does not follow obviously or It is evident from the state-of-the-art building solutions anticipated for cell-type equipment, portable or not, interactive devices, where in addition this system relies on industrial applicability.

DETAILED DESCRIPTION OF THE INVENTION

 Referring to the illustrated drawings, the applicant understands that it is pertinent to describe, by reading Figure 1, the constructivity of a traditional optical sensing module applied to electronic equipment (A) formed by a vertical screen (Tv) arranged vertically and the second one. horizontal screen (Th), this view is shown in detail through figure 2, which is superimposed on a base (Ba), whereby light emitting elements (LED) are mounted on the entire peripheral contour of the worktop. Under this horizontal screen (Th) is a watertight housing (Bx), isolating the image capture apparatus (Ca), see figure 1, like a digital camera, preventing the penetration of external light. According to the equipment constructivity shown in figure 1, the distance (h1) gives the exact measure of how voluminous the equipment is presented (A), this volume is necessary due to the need of camera distance (Ca) in relation to the screen. horizontal (Th).

According to the present invention and to solve the problem concerning the large volume of the sensing module, the novel compact optical sensing module was conceived, which presents a constructive concept revealed through the figures 3a; 3b; 3c and 3d respectively, where the camera (Ca) is positioned adjacent to the rear edge (Th2) of the screen surface (Th), notably a touch screen or multi-screen type. This camera (Ca) is directed towards the mirror surface of the new special mirror component (Es), notably a special mirror, which is positioned under and parallel to the screen (Th), and the a very small distance (h2), especially when compared to the distance (h1) found in a common optical sensing module, shown in figure 1. This embodiment brings with it a technical advantage, as it requires a special mirror (s) of reduced dimensions.

 Alternatively, a second embodiment for the compact optical sensing module disclosed by FIGS. 4a is disclosed; 4b; 4c and 4d respectively, where in this the front edges (Th1) and (Es1) of the screen (Th) and the mirror (Es) respectively are very close, where this condition is obtained thanks to a sharp inclination (In) of the screen ( Th). The advantage of this embodiment is that it allows the depth of the device (h3) to be minimized at the front edges (Th1) and (Es1) of the screen (Th) and special mirror (Es) respectively, ie the edges opposite the rear edge. (Th2) of the screen (Th) where the camera is fixed (Ca).

 In both configurations, the front edge (Es1) of the mirror surface of the special mirror (Es), farthest from the camera (Ca), can usually be specified flat, as the aperture angle of lenses typically used in the camera ( Ca) is sufficient to allow viewing of the entire front edge (Th1) of the screen surface (Th) opposite the camera.

Already in the region of the rear edge (Es2) of the special mirror (Es), that is, closer to the camera (Ca), there is a technical limitation on the functionality of this camera (Ca), where for the typically used lenses, it cannot be entirely is displayed if the mirrored surface is flat due to the short optical path between the camera (Ca) and said back edge region (Es2) of the special mirror (Es). For this reason, in both configurations, the rear edge region (Es2) of the mirror surface special mirror (Es) closest to the camera (Ca) is convex in shape to increase the angle. effective aperture, allowing full display of the screen surface (Th).

 In addition, between the anterior edge (Es1) and the posterior edge (Es2) the curvature of the mirrored surface (Es3) varies linearly, gradually passing from the convex profile to a flat profile, as shown in figure 5.

 In the claimed solution, in any of the possible configurations, the fact that the camera (Ca) is not positioned on the axis perpendicular to the center point of the screen surface (Th), as well as the convex shape of the mirror surface special mirror (Es) , introduce geometric distortions into the image, which should be corrected by the image processing software. However, the fact that the original image has some compressed areas relative to others implies a loss of resolution in the compressed areas after correcting the distortions. If necessary, a camera (Ca) higher than the resolution normally used may be employed to compensate for the loss of resolution caused by geometric distortion. However, whether a standard or higher resolution camera (Ca) is used, the mirror mirror surface geometry (Es) and the angle (In) between it and the bottom surface of the screen (Th) can be calculated, by mathematical and geometric methods to limit the resulting loss of resolution in the corrected image. By establishing a maximum tolerable image resolution reduction factor, the angle (In) between the special mirror (Es) and screen (Th) surfaces, as well as the rear edge profile (Es2) can be calculated. mirror surface of the special mirror (Es).

Within this context it is emphasized that the two embodiments disclosed above constitute extremes of a continuum of intermediate configurations in which the position of the mirror surface of the special mirror (Es) relative to the surface of the screen (Th) varies from the essentially parallel position between special mirror (Es) and screen (Th), less than the slight perceived convexity of the former) to the position in which the front edges (Th1) and (Es1) of the screen (Th) and special mirror (Es) surfaces touch, or are very close to each other.

 In a first alternative embodiment, designed for the compact optical sensing device described above to meet very effectively the proposed objective of "providing the thickness reduction of electronic equipment", a solution is presented that optimizes the aforementioned "thickness reduction". where the constructive concept of the improved compact optical sensing device is as revealed by figures 6, 7, 8 and 9 respectively, and where a horizontal screen (Th), notably a touch screen or multi-screen embedded touch ", perceives immediately adjacent to one of its edges (Th1) a first flat mirror (Es1), where in addition it is aligned to the same plane of this screen i

horizontal (Th). Just below the horizontal screen (Th) and the first flattened mirror (Es1) is defined a second flattened mirror (Es2), where the distance (H) between the two mirrors is minimal, ensuring the equipment an approximate tablet shape. Finally a camcorder (Ca) is positioned in an intermediate plane between the first flat mirror (Es1) and the second flat mirror (Es2) and still adjacent to the outer end of the first flat mirror (Es1), and still has angular inclination (Ag) with respect to the screen plane (Th) such that its objective lens captures the image i

reflected by the first mirror (Es1).

 However, it is noteworthy that, with the alternative configuration of the sensing module, regarding the dimensions of the screen (Th), it is verified that it presents an increased depth dimension, while the width dimension is kept unchanged and thickness dimension is reduced relative to the embodiment in figures 1 to 5.

With the addition of the first flat mirror (E1) and the second flat mirror (E2) in the constructive option presented in figures 6 to 9, in detriment of the hitherto used convex mirror, it is observed that There is an increase in the optical path taken by the light rays generated from the bottom of the screen (Th) to the camcorder lens (Ca), ie the light points emitted at the bottom of the screen (Th) are directed to the surface. second mirror reflection (Es2) which in turn reflects this signal to the reflection surface of the first mirror (Es1) where it is finally captured by the objective lens of the camcorder (Ca).

 Still in this condition one has that the "virtual position" (Pv) of the camcorder (Ca) with respect to the screen (Th), see figure 7, corresponds to the actual position (Pr) of this same camcorder (Ca ') knocked twice with respect to the flat mirrors (E1) and (E2). The second reflection allows, for the same virtual position (Pv) of the camcorder (Ca), to reduce the distance (H) between the screen (Th) and the lower flat mirror (E2).

 In addition, the displacement of the camcorder (Ca) to a new position located beyond the top mirror (E1) has the advantage of allowing the viewing of the entire lower useful area of the screen (Th), where to consolidate this condition of excellence the The camcorder (Ca) receives a moderately wide-angle lens, thus dispensing with the use of the convex mirror, as in the module model described in Figures 1 through 5, without however resulting in the use of the flat mirror (Es2). some kind of excessive geometric distortion.

The geometric distortions generated with the functionality of the module revealed in figures 6 to 9 are simpler in nature compared to those of figures 1 to 5, corresponding only to the usual perspective distortion resulting from viewing a plane from a camera. video (Ca) with optical axis "non-perpendicular" to said plane, as well as intrinsic distortions to the camcorder's own sensor and lens optics such as the "barrel-shaped" distortion typically observed in wide-angle lenses. Moreover, such distortions can be corrected by digital processing of the captured images, within the limits imposed by the loss of resolution due to the geometrical compression of certain parts of the image in relation to others, where, in case of necessity, one can employ a camcorder (Ca) higher than the resolution normally used to compensate for the loss of resolution caused by geometric distortion.

 To determine the thickness of the device's optical array, a maximum tolerable factor for image resolution reduction is established by geometric analysis, where the angular inclination (Ag) of the camcorder (Ca) with respect to the screen plane ( Th), as well as the distance (H) between the planes of this screen (Th) and the flat mirror (Es2), which determines the thickness of the device's optical assembly.

 In a first preferred constructional option, electronic equipment (A) (figures 10 to .16) equipment (A) is provided with a compact optical sensing module (a3) associated with a column (a1), where it has as its primary function providing the support at its upper part of a projection module (a2) and at its lower part a compact sensing module (a3), whereby an opening / closing device of the equipment is defined. In addition, this column (a1) has the secondary function of housing the control and information processing module (a5), where, lastly, the anterior vertical wall of this column (a1) is intended for the attachment of an information-emitting device ( a4).

It is noteworthy that it is mandatory for the column (a1) to maintain, on any supporting surface, uniform horizontal, the whole set formed by projection module (a2) and sensing module (a3) properly stabilized, since it is It is essential that the internal components of the aforementioned modules have an exact alignment with this support surface, due to the image projection generated by a projector component (12) on the surface of the screen component (6) of the compact sensing module (a3).

 Once the general constructive concept of the equipment (A) is revealed in the form of functional devices and modules, they are described in technical detail through the particular constructiveness revealed in figure 12.

 The opening / closing device of the equipment comprises that in the connection region of the projection module (a2) and sensing module (a3) with the ends of the column (a1) a pair of articulation mechanisms is defined, notably a articulation mechanism. (Art1) that allows radial opening / closing movements of the projection module (a2) and a lower articulating mechanism (Art2) that allows radial opening / closing movements of the compact sensing module (a3), this equipment ( A) in a closed condition of the projection modules (a2) and compact sensing (a3) is revealed through figure 12.

 The projection module (a2) is formed by a housing (10) that contains a sub-chassis (11), which has inside it a

An image projector component (12) where a first mirror (13) is mounted anteriorly and adjacent to it, specifically a first-face mirror, which has the auxiliary function of reducing the overall height of the equipment (A).

 I

whereas there is also a camera (14) positioned parallel to the image projector (12), the focus of which is directed to the table surface (9) defined in the sensing module (a3);

The sensing module (a3) is formed by an unprecedented optical sensing technology, consisting of a structure (4) that supports inside a screen (6), or monitor, with touch screen technology. and or "multi-touch", which in one possible embodiment can be a screen with different transduction technology, translated in the form of a memory effect sensing and erasing device disclosed in patent application filed 06/10/2008 entitled "Integrated Interactive Device System, With Embedded Memory Sensing And Minimization Device, Applied In Equipment Operated By One Or Multiple Users ", where it is formed by a screen composed by a set of three plates, being a protection plate; a damping and return plate and a contact plate that is superimposed on a top (7), where this assembly is delimited by a frame (8) whose internal contour has defined a plurality of "LEDs" elements.

 It is further added that this screen (6) in the embodiment disclosed herein can be positioned both parallel to the support surface of the equipment itself (A), and may also have a certain inclination (In), as revealed in Figures 4a and 12, where the specification of this inclination may vary depending on the specific needs of each equipment project (A), ranging from greater than zero degrees to less than 90 degrees.

 Already at the back of this screen (6) is fixed a camera (9) which in turn is connected to the control and information processing module (a5).

 In addition, a calculated surface mirror (5) which has odd geometry formed from a flattened anterior area and which migrates this surface area to a convex geometry at its posterior end.

 In addition, the compact sensing module (a3) can be built-in with all sorts of optical sensing technology, such as;

Information emitting device (a4): defined in the form of a monitor (3), such as an LCD or Plasma monitor, in all sorts of dimensions, such as 20 in; 22 in; 26 in among others; and - Control and information processing module (a5): composed of all kinds of electronic elements (such as PC, video card, sources, controls and ventilation system), which are activated by commands (a6 ') arranged on the button menu form on the back wall of the column itself (a1).

 The shape (design) and dimensions of the equipment (A) were marked by the technical characteristics that govern the dimension of the sensing module (a3), which in turn is governed by the ratio of the screen (6) - mirror (5) set. - camera (9), which in turn determined the angle of inclination (In), thus converging on determining the size of the image to be projected by screen (6), and hence the other elements. This image size in turn is limited by the optical characteristics of the image projector (12), determining its position as well as the mirror (13) attached to it.

 Thus, the use of this mirror (13) next to the camera (9) is justified in order to decrease the overall height of the equipment (A) and give it an aesthetic continuity.

Although the above-described embodiment of electronic equipment provided with interactive devices is very effective, another form of locking and locking between modules is presented which optimizes the arrangement thus far, as it provides the equipment with a stable condition when in use. position of use since it consists of three main modules (figures 17 to 23), where the optical sensing module (M1) is formed by a base or table, where effectively the touch device is mounted, which is revealed in detail by figure 23, composed of the camera component (Ca), which is provided with a wide aperture lens, a pair of mirrors (Es1) and (Es2) respectively, the touch surface (Su) itself, which can be made acrylic, fabrics and related materials, a light source in the form of white light LEDs for example, and on the table can still be defined individual sound interfaces (In1), c how microphone and headset, a multi-memory card reader (In2) and a USB port (In3).

 The control and information processing module (M2) is provided with all control electronics, such as PC, wireless communication interfaces, sources, speakers, video conferencing camera, among others, particularly in the extreme upper and lower part. A central depression is defined as a depression (Al) which is intended to accommodate the mirror (Es3) of the projection module (M3) when the equipment has all modules closed and locked;

 The projection module (M3) is formed by an image projector device that with the help of two mirrors (Es3) and (Es4) respectively, projects images onto the table of the sensing module (M1), where the first mirror (Es3 ) is fixed to the projector frame and the second mirror (Es4) is attached to a concealed base which can have 3 positions namely:

The. Closed for transportation,

B. Open at 60 degrees for table projection; ç. Open at 110 degrees for projection and support of the wall control and information processing (M2) module; The articulation and locking and unlocking mechanism is notably developed for locking or unlocking the sensing module (1) and information processing and control module (M2), formed by a first joint (Ar1), in the form of a hinge system. , in particular actuated by a side switch, and in addition to the upper end of the table of the sensing module (M1) is defined a socket (Ga2) to which a hook (Ga1) mounted at the upper end of the interference is actuated. control and information processing module (M2).

Finally, a second hinge (Ar2) is defined as a hinge system mounted on the upper end of the control and information processing module (M2) and the upper end of the projection module (M3) which ensures a 180 ° articulation of this second in relation to the second module (M2), where when in the position of retraction and closing of the equipment said articulation (Ar2) ensures the accommodation of the main body of the projection module inside the depression (Al) of this second module. (M2);

 The equipment stabilizer bracket consists of a support piece (1) mounted on the back of the sensing module (M1) to balance the assembly when in the "open" position. It is noteworthy that this stabilizing support is an integral part of the interlocking mechanism itself which is the object of claim.

 It is noteworthy that the touch screen (th) of the equipment, when touched by a stick, can be used as a surface on which to write and draw, simulating the spelling performed by a pen, chalk or equivalent.

 When embossed materials are placed on the screen (Th), it is possible to associate with tactile marks and lines, sounds, and other actions of the computer embedded in the equipment. This use enables tactile learning, especially for people with vision impairments.

 Objects placed on the surface are identified by one or more cameras fixed above the monitor and allow board function for interactivity such as games and others.

 The equipment can provide headphone jacks, such as "audio cap" technology, allowing coordinated communication between people without interfering with normal conversations, and sound from the speakers can be reduced or eliminated. , not disturbing others around the equipment.
