Description

The invention relates to a display device for displaying and manually inputting information. The display device comprises a touch-sensitive first visual display unit having at least one input area for swipe gestures, a guide for a user's finger, a first swipe area recognizer for recognizing the at least one input area in which the swipe gesture is executed, and an output device for generating output information Dependence of the recognized input area on. The touch-sensitive first visual display unit typically has an active display based, for example, on an OLED, TFT and / or LCD technology (OLED = organic light-emitting diode, TFT = thin-film transistor, LCD = liquid-crystal display ). However, in principle, it is also possible to realize the present invention when the visual display unit is a touchpad with a purely passive display (for example, with labeled operation fields). In the present invention, if more than one visual display unit is present, but only one of which is touch-sensitive, the touch-sensitive visual display unit is considered to be the first display unit, irrespective of whether the single touch-sensitive visual display unit is a display unit. which is portable or permanently mounted in the vehicle, and whether the sole touch-sensitive visual display unit is a central display, a display located behind the steering wheel, or an otherwise arranged display, such as a front passenger display or a decorative display , acts.

Moreover, the invention relates to a vehicle with such a display device.

Furthermore, the invention relates to a method for manually entering information. The method includes the following. In a first step, a swipe gesture is performed with a user's finger on a touch-sensitive first visual display unit along a guide for the user's finger. In a second step, an input area of the touch-sensitive first visual display unit is detected in which the swipe gesture is executed. In a third step, output information is generated as a function of the recognized input area.

From the DE 10 2006 060 520 A1 For example, a control and display system for a vehicle is known, which has a visual display unit and a control unit, which is arranged separately from the visual display unit (for example on a steering wheel of the vehicle). A menu structure displayed on the visual display unit includes a main menu at an upper edge of the visual display unit and a submenu at a left edge of the visual display unit. By means of the operating unit inputs can be made via the main menu and the submenu.

In the automotive environment touch-sensitive display units (touch screens) with additional rotary push button are known. Functions that can be triggered by touch are displayed here as buttons that a user can actuate by touching with his or her finger. In today's touch-sensitive display units (touch screens), the possibilities for generating a haptic feedback are usually limited to an output of vibration signals. In the automotive environment, especially when driving commercial vehicles, the user can not reliably perceive vibration signals.

In today's commercial vehicles of the product line ACTROS ^® an operating concept is realized, which is labeled "stacks &cards' and the driver allows a dummy operation. If the operating concept was transferred faithfully to a touch screen, the previous blind operation would be lost. However, it is desired that rapid changes between applications (for vehicle, navigation, infotainment) should be possible without the user having to look away from the road to aim at one of the menu items displayed on the touch-sensitive display unit (touch screen) Selection offered.

The DE 10 2013 105 507 A1 describes an input unit for a vehicle, which is designed as a horizontal wiping field for blind operation. Among other things, a physical barrier made of a piece of plastic is proposed for guiding a finger of the user, which divides the input unit into segments. The subdivision forms different wiping fields, to which different functions are assigned. The known input unit has the disadvantage that the barrier covers part of the total available display area, which is then no longer available for displays (for example, for a full screen display on the entire visual display unit).

It is an object of the present invention to provide a display device for manually inputting information that allows rapid switching between applications without requiring the user to look away from the road to target one of the menu items displayed on the screen touch-sensitive display unit are displayed for selection, the total available display area can be used for ads.

This object is achieved by a display device having the features of patent claim 1, a vehicle according to claim 9 and by a method having the features of patent claim 10. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.

A display device for displaying and manually inputting information according to the present invention comprises a touch-sensitive first visual display unit having at least one swipe gesture input area, a user finger guide, a first swipe area recognizer for recognizing the at least one input area where the swipe gesture is performed, and an output device for generating output information depending on the detected input range. The guide is an edge of an outer edge of the touch-sensitive first visual display unit.

The edge can, but does not have to, wrap around the entire first visual display unit. The edge may be an edge of a frame of the first visual display unit. This is not mandatory. There are smartphones whose display extends over a rounded front edge of the smartphone. For example, it is also conceivable to provide for the display device according to the invention a tablet computer which has a touch-sensitive display with one or more rounded leading edges. In this case, a rounded leading edge can be used as a guide for the user's finger. To find menu items without looking, the rounded leading edge or rounded front edges of the display may have one or more protrusions, depressions, and / or roughenings.

An inventive vehicle has a display device according to the invention.

The method for manually entering information according to the invention comprises the following. In a first step, a swipe gesture is performed with a user's finger on a touch-sensitive first visual display unit along a guide for the user's finger. In a second step, an input area of the touch-sensitive first visual display unit is detected in which the swipe gesture is executed. In a third step, output information is generated as a function of the recognized input area. The guide for the user's finger is an edge of an outer edge of the touch-sensitive first visual display unit.

One concept of the invention may be seen in that the guide is an edge of an outer edge of the touch-sensitive first visual display unit. As a result, a portion of the display device is used to guide the finger of the user, which is typically present anyway, and it can be used the total available display area for ads. Alternatively or additionally, as a guide, a displaceable rail or a further edge or rail can be used for swiping gestures.

In a preferred embodiment, the first wiping area recognizer is prepared to recognize at which portion of one of the edges of the outer edge a wiping gesture is or has been performed. As a result, individual sections of one of the edges of the outer edge can each be assigned a specific function, preferably a function of a main or sub-menu item.

It is advantageous if the first wiping area recognizer is prepared to distinguish whether a wiping gesture was or was performed along one of the edges of the outer edge, or whether the wiping gesture was or was performed in a middle touch area of the touch-sensitive first visual display unit. As a result, input areas that are usable by a user without looking (ie blind) are (because they are purely haptic findable), functionally separated from a middle touchpad that is not usable by a user without looking (ie not blind) (because it is not purely haptic is findable).

An advantageous development provides that the display device has a main menu generator for generating a main menu with main menu items that are selectable by swiping gestures. As a result, the user can be offered input areas for selecting a main menu item from a set of several main menu items.

It is particularly advantageous if first markings are arranged on the outer edge, which can be perceived haptically with the finger, and whose arrangement locally corresponds to display locations of the main menu items. This allows the user to find at least one main menu item without looking (so blind) purely haptic. In principle, it is also conceivable that the shape of at least one individual mark can be changed by means of an actuator. For example, a marker can be sunk slightly into or out of the edge by means of the actuator when the associated main menu item is activated (and vice versa when it is deactivated).

It is also preferred if the display device has a submenu generator for generating at least one submenu with submenu items that can be selected by swiping gestures. As a result, the user can be offered input areas for selecting a submenu item from a set of several submenu items.

A further development provides that on the outer edge second markers are arranged, which are haptic perceptible with the finger, and their arrangement with display locations of the submenu items locally corresponds. This allows the user to find at least one submenu item without looking (ie blind) purely haptic. In principle, it is also conceivable that the shape of at least one individual mark can be changed by means of an actuator. For example, a marker by means of the actuator can be slightly sunk into the edge or pushed out of it, if the associated submenu item is activated (and vice versa if it is deactivated).

Depending on the application scenario, it is expedient if the display device has a second visual display unit. With the second display unit, the same contents as on the first display unit can be displayed at a further location in the vehicle or outside the vehicle (for example, for a passenger or a warehouse worker). Alternatively or additionally, a second display unit may also be provided to display other information at the same time than on the first display unit. In the present invention, if more than one visual display unit is present, but only one of which is touch-sensitive, the touch-sensitive visual display unit is considered to be the first display unit, irrespective of whether the single touch-sensitive visual display unit is a display unit. which is portable or fixed in the vehicle, and whether the only touch-sensitive visual display unit is a central display or a display located behind the wheel. Independently of this, besides the first and second visual display units, further similar visual display units may be provided which are touch-sensitive or non-touch-sensitive.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

The in 1 shown cab FS for a commercial vehicle workstation has a steering wheel LR and a display device AV with a first AE1 and a second AE2 visual display unit. The first visual display unit AE1 is touch-sensitive and arranged in, on or on a dashboard AB next to the steering wheel LR. The second visual display unit AE2 is arranged in a dashboard AB behind the steering wheel LR. With the second visual display unit AE2, the same contents as on the first visual display unit AE1 can be displayed at a further location in or outside the vehicle FZ. Alternatively or additionally, a second visual display unit AE2 can also be provided to display other information at the same time than on the first visual display unit AE1. An advantageous development provides that the second visual display unit AE2 is arranged in a holder H, from which they are taken out for use and outside the vehicle FZ (for example, for loading and unloading, to operate an on-board crane or in an office or accommodation as a universal tablet computer) can be used. For an optional indirect operation of the first AE1 and the second AE2 display device, an operating unit BE is arranged in the steering wheel.

This in 2 schematically shown vehicle FZ has an infotainment system IS and a display device AV, which is connected to the infotainment system IS. The display device AV has a first visual display unit AE1, a main menu generator HE, a submenu generator UE, a first wiper area recognizer WE1 and an output device AD. The first visual display unit AE1 is connected to the main menu generator HE, the submenu generator UE, and the first wipe area recognizer WE1. The output device AD is connected to the first wiping area recognizer WE1.

Typically, the infotainment system IS is prepared for the main menu generator EH VH defaults to be displayed on the main menu items PH (see 3 and 4 ). Alternatively or additionally, the infotainment system IS is prepared for the submenu generator EU specifications VU to be displayed submenu items PU (see 3 and 4 ).

The first visual display unit AE1 is prepared to detect swipe gestures WG executed with one or more fingers of a user. The first wiping area recognizer WE1 is prepared to evaluate acquisition information EI resulting from the swipe gestures WG and to determine by means of the evaluation in which input area BL, BO, BR, BU the swipe gesture WG to be recognized and evaluated takes place or took place, and this swipe gesture information WGI output to the output device AD. In addition, in the first wiping area recognizer WE1, recognition and output can also take place in which direction and / or at which speed and / or with which contact pressure a wiping gesture WG is executed or executed. For example, it can be provided that a selection of a main menu item PH or submenu item PU takes place with a swipe gesture WG which is executed from the main menu item PH or submenu item PU to the right or was (whereby, for example, a function of the infotainment system IS or another function of the vehicle FZ switched on or activated) and that a switching off or deactivating the function of the infotainment system IS or the other function of the vehicle FZ with a swipe gesture WG takes place, which is carried out from the main menu item PH or submenu item PU to the left or was.

A preferred embodiment provides that for the input of swipe gestures WG between a top BO and a left BL input range is distinguished. For example, the upper input area BO for a main menu MH (see 3 and 4 ) and the left input area BL for a submenu MU (see 3 and 4 ) be provided. It is also conceivable that a lower input area BU is provided for a first further main or submenu (not shown in the figures). Alternatively or additionally, a right input area BR can also be provided for a second further main menu or submenu (not shown in the figures). Another preferred possibility is that the lower BU and / or the right BR input area is provided for inputting quasi-analog inputs. For example, it can be provided that a swipe gesture WG in the lower input area BU is provided to select (by scrolling or scrolling further) a radio station from a frequency, channel or program scale or to select a song title from a list of titles. Accordingly, it can be provided, for example, that a swipe gesture WG is used in the right-hand input area BR to increase or decrease a volume or a display brightness.

In an optional supplement to the display device AV, the display device AV has a second visual display unit AE2 and a second wipe area recognizer WE2 (the dashed lines of the lines indicate the optionality). If the second visual display unit AE2 is present at all, it is connected to the main menu generator HE, to the submenu generator UE and to a second wiper area detector WE2. The output device AD, which is then also connected to the second wiping area recognizer WE2, can also be provided to prioritize a first swipe gesture information WGI from the first visual display unit AE1 relative to a second swipe gesture information WGI2 from the second visual display unit AE2 (in particular if the two swipe gesture information WGI, WGI2 are contradictory).

On an outer edge R of in 3 shown visual display unit AE1, AE2 is arranged at least one haptic perceptible mark Mi. The haptic perceptible mark Mi may be or include, for example, a bulge or indentation. A further development provides that at least two of the haptically detectable markings have a different shape, the difference (for example, in terms of expansion in the area and / or grandeur and / or roughness of a surface of the haptic perceptible mark Mi) is palpable. For example, the bulges on the outer edge R of the visual display unit AE1, AE2 can alternate with indentations so that a user better differentiates and lightens the haptic markings Mi (when sliding his finger along or along the outer edge R of the visual display unit AE1, AE2) can count blindly. The reference symbols KL, KO denote inner edges of the outer edge R. The figure shows main menu items PH, submenus PU and associated input areas BL, BO, BU, BR for swipe gestures WG. Typically, the first wiping area recognizer WE1 is prepared to recognize at which portion Ai of one of the edges KL, K0, KR, KU of the outer edge R a wiping gesture WG is or has been performed. As a result, individual sections Ai of one of the edges KL, KO, KR, KU of the outer edge R can each be assigned a specific function, preferably a function of a main or sub-menu item PH, PU.

The middle touchpad TF (playfield) is provided for a per se known mouse pointer control by means of inputs such as typing, multiple tapping, dragging and releasing, wiping with one or more fingers. For example, the center touch panel TF may be used to concurrently set azimuth and elevation of a side view mirror or to select a location on a map displayed on the visual display unit AE1, AE2 or a map displayed on the visual display unit AE1, AE2 to move horizontally and / or vertically.

At the in 4 shown second embodiment of a visual display unit AE1, AE2 are the haptic perceptible marks Mi surveys (and / or indentations), which reach up to an inner edge KL, KO of the outer edge R of the visual display unit AE1, AE2. The example shown in the figure shows that blind spots of an operating field BFOL, BFUL, BFUR (selection buttons) and corners ELO, ELU, ERU of the outer edge R can be used as haptic perceptible mark Mi. The operating field BFOL in the upper left corner ELO serves here for a back function, and the operating field BFUL in the lower left corner ELU serves as a list scroll function for respective subsystems. The operating field BFUR in the lower right corner ERU can be used to call up a display of additional or detailed information (not shown in the figures).

The 5 shows that alternatively or additionally, a second menu column MS2 can be provided for a further sub-menu MU3. In the example shown in the figure, the second menu column MS2 contains titles of selectable music albums (in 4 generally referred to as "Info ..."". A music track MT to be played is selectable in a further column which is located to the right of the second column MS2 and is arranged in a touch panel TF. For applications where short texts or symbols (icons) are sufficient in the second menu column MS2, the second menu column MS2 need not be as wide as in the figure, leaving more room for displaying information displayed in the center touch panel TF are.

Alternatively, a logical vertical or horizontal division of the display area of the first AE1 and / or the second AE2 visual display unit (not shown in the figures) is conceivable. With a half vertical division, a first submenu MU is then selectable, for example, with a left part of the set of main menu items PH, which is displayed on the left edge of the display unit AE1, AE2, and with a right part of the set of main menu items PH a second submenu MU2 selectable , which is displayed on the right edge of the display unit AE1, AE2. Such a division of the display unit AE1, AE2 and their input options has the advantage that a user can remember well an arrangement of menu items PH, PU, especially if he knows, for example, that a driver facing part of the display unit AE1, AE2 and their Input options (especially the driver-facing submenu) is rather assigned to automotive functions (such as exterior mirror adjustment) while a passenger facing part of the display unit AE1, AE2 and their input options (in particular the passenger facing submenu) is more associated with infotainment functions (such as station selection).

The in 6 shown procedure of a procedure 100 for manually entering information comprises the following method steps. In a first step 110 For example, a swipe gesture WG is performed with a user's finger on a touch-sensitive first AE1 or touch-sensitive second AE2 visual display unit along a guide G for the user's finger. In a second step 120 an input area BL, BO, BR, BU of the touch-sensitive first AE1 or touch-sensitive second AE2 visual display unit AE1 is detected, in which the swipe gesture WG is executed. In a third step 130 an output information AI is generated as a function of the recognized input range BL, BO, BR, BU. The guide G for the user's finger is an edge KL, KO, KR, KU of an outer edge R of the touch-sensitive first AE1 or second AE2 visual display unit. Respective corners, ie intersections of respective ones of the edges, may have additional informational content.

An embodiment according to the invention provides that the first AE1 visual display unit is touch-sensitive (optionally, this also applies to the second visual display unit AE2). Manual inputs can by means of a control unit BE, which is located for example in the steering wheel, or the touch-sensitive first visual display unit AE1 done. Haptic perceptible marks Mi are arranged on an upper edge KO of the first visual display unit AE1, at which a main menu MH is displayed. Alternatively or additionally, tactile markings Mi can be arranged on a left edge KL of the first visual display unit AE1, at which a submenu MU is displayed. Preferably, the wiping areas BO, BL at the upper KO and left KL edge of the first visual display unit AE1 of wiping areas BU, BR of the lower KU and the right KR edge of the first visual display unit AE1 are functionally decoupled. Moreover, it is expedient if swiping gestures WG are functionally decoupled along the upper edge KO or along the left edge KL of gestures G within the middle touchpad TF of the first visual display unit AE1.

The two-dimensional operating concept with side-by-side main menu items PH and sub-menu items PU (or main menu items PH arranged one under the other and sub-menu items PU arranged side by side) promotes intuitive user navigation via many input fields. In addition, a user of the display device AV is made easier to keep track of where in a menu structure, a display device AV is currently operational. In particular, even when changing a menu level, the user can already see in advance which menu level is reached by an input process WG. This minimizes the need for a look to the display AV and contributes to improved traffic safety.

Regardless, it is advantageous if the display device AV for a consistently redundant operability is prepared at any time between a direct operation of the first display device AV by touching (touch) the first display unit AE1 and indirect operation by means of a control unit BE (for example Touchpads) of the first display device AE1 to change. As a result, advantages of direct operation (for example by means of a touchscreen) are combined with advantages of indirect operation (for example by means of steering wheel buttons). The same concept can also be applied to the second display device AE2.
