CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of the German Utility Model Application No. 20-2014-103-215.0, filed Jul. 11, 2014, and entitled “Elektronisches, visuelles Gerat, das eine flexible beziehungsweise biegbare Vorrichtung zur optischen Signalisierung von veranderlichen Informationen, ein flexibles beziehungsweise biegbares Gehause mit mindestens einem Gelenk/Scharnier and ein Regel-/Steuerungssystem besitzt”, which is hereby incorporated by reference in its entirety. 
       BACKGROUND 
       [0002]    1. Field of the Disclosure 
         [0003]    The present application relates generally to flexible display devices and to computing devices with such a display. More particularly, the present invention pertains to stationary flexible display devices and to stationary and portable flexible computing devices with at least one flexible display screen and at least a three-dimensional sensor as well as flexible display devices 
         [0004]    2. Description of the Related Art 
         [0005]    People are using various types of devices with display devices having various dimensions, such as a television set, a stationary computer system, and a mobile computer system, to view content for various personal and professional reasons. The typical display device of such devices has a flat screen and is either a vertically standing display, a horizontally lying display, or a display held at an angle. But display devices are not bound to a flat shape. For example, one direction of technological development are display devices with flexible screens or/and combined vertical and horizontal screens. 
         [0006]    Furthermore, for most people from many different disciplines a desk with a computer system is the main workspace. Such a typical computer workplace integrates horizontal and vertical surfaces into the workspace and encompasses one or more vertical displays showing digital content and a larger horizontal area containing input devices, such as a mouse and a keyboard, a paper-based document, and everyday objects. Also, touch recognition technologies have combined the advantages of traditional input metaphors with digital documents. For example, a tablet computer allows high precision stylus input for graphic design, a digital pen enables annotations on physical paper, and multi-touch gestures provide an intuitive way to transform and modify digital data. 
         [0007]    Many systems have been proposed that use vertical and horizontal interactive surfaces within a single computer workplace. These systems provide a large interactive area and allow to move digital objects across multiple displays. 
         [0008]    However, despite all the advantages these interfaces have barely found their way into everyday workspaces yet. Some reasons might be that these two areas are clearly separated, which makes it hard to move documents from one surface to the other, and that each area employs a different interaction technique. For example, we use a mouse for drawing on vertical displays but a physical pen to annotate a paper-based document. A workspace that allows continuous interaction between both areas. Moreover, these systems suffer from a lack of spatial continuity. Gaps between adjacent displays suggest isolated interactive areas, objects belonging together may be separated across gaps between display devices, and splitting objects across device borders impairs search accuracy and steering performance. Eventually, these setups limit the applicability of for example direct manipulation, as movement trajectories are interrupted when dragging a finger or pen from screen to screen. 
         [0009]    Another direction of technological development related with computer workspaces are display devices, which combine the vertical and horizontal screens, like for example the so-called holobench or workbench as shown in  FIG. 1 . A holobench  100  is a semi-immersive projection display device for working in virtual reality environments, that is constructed by two screens  112 ,  114  put together in an L-shaped display providing one vertical backplane projection screen  114  and one horizontal backplane projection screen  112 , and using the active stereo-projection mode for the rendering of stereoscopic images by the projectors  102 ,  104  beaming images over the mirrors  106 ,  108  on the screens  112 ,  114  to generate a three-dimensional impression for a user wearing shutter glasses. With the help of a position detecting and motion tracking system and a related control system the position, orientation, and movement of the user&#39;s head are captured and the perspective of the three-dimensional scene displayed with the holobench is altered by a rendering circuitry accordingly. 
         [0010]    However, a problem with these display devices is that the horizontal and vertical screens are perceived as isolated areas and that by the L-shape edge a smooth, fluent transition of the displayed content cannot be relaized between the vertical and horizontal screens. 
         [0011]    As part of the research project “BendDesk” shown in  FIGS. 2A and 2B  a desk environment  200  has been presented that merges a vertical backplane projection screen  216  and a horizontal backplane projection screen  212  into one interactive workspace using a curved projection screen  214  between the vertical and horizontal screens. Two projectors  202 ,  204  for the graphical output and three two-dimensional cameras  222 ,  224 , and  226  for the multi-touch input are used. The curved projection system provides a large multi-touch area  211  within the user&#39;s reach and allows uninterrupted, seamless dragging gestures across the entire display screen  211 . This workspace can be used to display any digital content like documents, photos, or videos. The multi-touch technology allows the user to interact with the entire display screen  211  by direct manipulation and multi-touch gestures. Special care was also taken in relation with the ergonomics, so that users can comfortably sit at the desk environment and place everyday objects on it. 
         [0012]    In the research project “Curve” similar ergonomics and design considerations for building a curved multi-touch table have been presented. The multi-touch table also consists of a vertical and a horizontal interactive screen seamlessly blended by a curved screen segment to bridge the gap between physical desks or tables and digital desktop environments. 
         [0013]    As part of another research project “Mirage Table” the technologies of the curved desktop environment and the holobench have been integrated with a desk environment including a curved projection screen, a stereo projector device, a pair of shutter glasses, a stereo sync emitter, a range camera or depth camera respectively three-dimensional scanner device comprising an infrared projector and a camera, and employing a variant of image-based three-dimensional reconstruction to generate a related dense three-dimensional image of objects and individuals, and a special microchip to track the movement of these objects and individuals in three dimensions. The curved workbench also supports tangible interfaces. 
         [0014]    But still not all problems have been solved with these curved display devices, and accordingly several areas of technical problems and general demands have been determined. 
         [0015]    Firstly, the display devices respectively workspace environments lack of display quality. The applied backplane projection and frontplane projection technologies do not result in a high brightness compared to directly observed display devices. Also, the frontplane projection has the disadvantage that the user might get between the projector and the projection screen, so that parts of the projected image are projected on the user and not on the projection screen. 
         [0016]    Secondly, solving the problem of an L-shaped display device with curved display devices leads to other problems. For example findings of the research project “BendDesk” showed that dragging across a curve is significantly slower than on flat surfaces, a smaller entrance angle when dragging across the curve yields in a longer average trajectory and a higher variance of trajectories across users, and the curved shape of the system impairs virtual aiming at targets. In addition, the proposed L-shaped and curved display devices either are based on multi-touch user interfaces or on three-dimensional display devices that need special glasses for viewing. 
         [0017]    Thirdly, the display devices are large and unhandy. Flexible and particularly rollable visual display devices may be a solution to these problems, but then a flexible display device needs a housing, a frame, or some other means to keep its shape and to be foldable or rollable. Another solution is to have a portable variant of such a stationary display device with a related computer system arranged in a housing as well. 
         [0018]    Fourthly, flexible devices need a sensor for a contactless user interface, a three-dimensional camera or a three-dimensional scanner device for detecting the position and orientation and tracking the motion of arbitrary objects and features of a user, such as a hand, a head, an eye, and another body feature, for capturing informations related with gestures for example, and for making three-dimensional images. Portable variants of such as display device may also have a sensor for tracking their own motion. 
         [0019]    Furthermore, the combination of horizontal and vertical interactive surfaces has mostly been applied for displaying scientific data and computer generated models, and realizing collaborative workspaces, remote desk environments, and remote collaboration and communication systems. But there is still a demand for more functionalities and applications. 
       SUMMARY 
       [0020]    In accordance with the purpose of the invention, as embodied and broadly described, the invention pertains to a flexible electronic visual display device, and extensions of such an electronic device to a flexible stationary computer system and a flexible mobile computer system. The disclosed electronic device features a relatively large, interactive area in respect to a specific device class, as well as different input modalities, output modalities, and further functionalities and application possibilities, which also provide the foundations for novel functionalities and applications. 
         [0021]    The basic electronic visual display device comprises a flexible display device, at least one three-dimensional sensor, at least one control system, a flexible housing containing the electronic components, and an adjustment means for the housing. In some embodiments, the flexible electronic visual display device can have additonal two- and three-dimensional sensors of various types, an image projector, a wireless communication interface, and a wireless power supply. For independent use some embodiments of the flexible electronic visual display device can also comprise an electronic module including at least one processor and at least one data memory, and also at least one electrical energy storage device being contained in the housing as well. 
         [0022]    Several embodiments of the present invention provide different basic types of the flexible display device, which can be a liquid crystal display, a light-emitting diode display, a quantum dot based light-emitting diode display, a laser diode display, and an electronic paper display, and also different functional types, which can be a multi-layered display and a three-dimensional display, to name just some preferred examples. 
         [0023]    In order to achieve the above and other objects, several embodiments of the present invention also provide different types of two- and three-dimensional sensors, and different types of related control systems. With these components the electronic display device is able to capture various optical, acoustical, and other physical information by the sensors, and to processe the captured sensor information, execute predetermined functions, and issue corresponding commands to control other electronic components of the electronic display device by related control systems accordingly. A preferred class of functionality provided in this way comprises various types of user interfaces, particularly graphical user interfaces and natural user interfaces, including direct manipulations by multi-touch, gestures, and also kinetic user interfaces, including again tangible user interfaces, as well as voice user interfaces, which all can be combined with each other to realize multimodal user interfaces. 
         [0024]    But also the display device itself can be controlled with these sensors and related control systems. For example, a three-dimensional sensor can be used to detect the position and motion of a user&#39;s feature with respect to the electronic device, and in the case of a portable variant the position and motion of the device itself, and then provide these captured information to the control system of the visual display device. The control system can update the viewpoint and viewing angle of a virtual camera of the rendering pipeline in response to the users&#39;s changed viewpoint or/and viewing angle on the displayed scene with respect to the electronic device. This allows the realization of for example a glasses-free flexible autostereoscopic display device. 
         [0025]    Another provided functionality is based on the usage of an optical three-dimensional sensor as a three-dimensionsal scanning device to scan and digitalize objects put on the horizontal surface area of the display device for further use. 
         [0026]    In some embodiments the invention also provides an image projector for projecting additional information on the display output and images on objects put on the horizontal surface area of the flexible electronic display device, and for providing a pointing means controlled by a user, the electronic display device itself, or/and another electronic device connected to the flexible electronic visual display device. 
         [0027]    Several embodiments may comprise a wireless electric power link device arranged within the horizontal surface, which can be configured to wirelessly receive electric power from an external power supply, and a wireless charging means, which can be configured to supply other electrically operated devices layed on the horizontal surface with electric power. 
         [0028]    A further aspect behind the invention is the support of a user through improved ergonomics and easier handling by providing a flexible directly observed display device with a flexible housing and an adjustment means for the housing, as it is discussed in different ways in the following. 
         [0029]    Firstly, the directly observed display device provides a brighter presentation of visual information compared to visual systems, which are based on backplane or/and frontplane projections. Furthermore, due to the curved surface no edge at the joint of the vertical and horizontal surfaces exists and therefor the presentation of visual information is perceived as seem less on the one hand and the quality of for example a three-dimensional presentation is increased on the other hand. 
         [0030]    Secondly, the usage of (everyday) objects is supported. With the exception of special purpose desks, such as drawing tables for example, office desks and other tables are usually horizontal, so that people can put physical objects on them. In contrast, the possibilities of placing objects onto a tilted surface, even at small angles, are limited. But with a flexible display device the horizontal surface can be adjusted as needed, so that some areas of a surface are tilted while other areas of the same surface are horizontal. Additionally, the flexible display device can be adjusted as often as needed with an adjustment means of the housing, thereby increasing its useability and supporting a more convinient use of such a display device having vertical and horizontal surfaces. 
         [0031]    Thirdly, tilting the vertical surface backwards would reduce its reachability at the top, but the user should be able to sit and stand in front of the electronic display device in a comfortable position and to reach the entire input area without much effort. With for example a three-dimensional camera and a related control system using the flexible electronic display device does not depend on direct manipulations by touch anymore. Furthermore, the vertical surface can be adjusted in such a way that viewing and using the device is as much as comfortable and ergonomic as possible. In addition, the variable adjustment means allows tilted vertical and horizontal surfaces if needed in the case of a television set or a holobench, workbench or homebench standing on the ground, or in the case of a tablet computer or another portable device being held in the hands by a user. 
         [0032]    Fourthly, the electronic visual display device is flexible at at least one position and in at least one dimension, and depending on a related variant can even be bent in two degrees of freedom with respect of a single dimension. The joint means of the device housing allows its opening, bending, and closing without falling below the permissible bending radius of and without applying stress on the flexible electronic visual display device. By the flexible housing the display device is also protected at its backside against mechanical damage. 
         [0033]    Moreover, the flexibility offers easier and safer ways to transport and store such electronic visual display devices, which are relatively large dimensioned in respect to specific device classes. For example, in some embodiments the flexible display device can simply be fold together or rolled up. 
         [0034]    Fifthly, for independent usage apart from an external power supply and an external computing device some embodiments of the electronic display device can also comprise an electronic module including at least one processor and at least one data memory, and also at least one electrical energy storage device being contained in the housing as well. 
         [0035]    Through the combination of the different types of the flexible display device, one or more sensors, control systems, electrical energy storage devices, and other optional electronic components, many different variants of the electronic visual display can be constructed. This permits the disclosed flexible electronic visual display device to provide a broad range of functionalities and application possibilities, and to assume novel functionalities and applications, particularly in the fields of virtual reality, augmented reality, and mixed reality environments, and to support new ways of using display devices, and stationary and mobile computing systems. 
         [0036]    The invention may be implemented in numerous ways. Exemplary preferred embodiments of the present invention are a stationary flexible electronic visual display device with a three-dimensional image sensor, a three-dimensional scanner device, or/and an image projector device, and a flexible tablet computer with a three-dimensional camera that are discussed below, but not limited to such stationary and portable electronic devices. Depending on its dimension and features the disclosed invention applies to for example a mobile phone or cell phone, specifically a smartphone, a tablet computer, an all-in-one personal computer, a television set, a curved holobench, workbench, and homebench, and such alike as well. In this conjunction, all the components or electronic units, which form the various parts of said flexible electronic visual display devices and which are known to those skilled in the art in the field of computer engineering, will not be described in detail. Only said components necessary to the elaboration of preferred embodiments of a flexible electronic visual display device according to the invention will be described. 
         [0037]    Other systems, methods, features, advantages, objects, and further areas of applicability together with a more complete understanding of the disclosure will be, or will become, apparent and appreciated to one with skill in the art upon examination of the following figures and detailed description, or may be learned by practice of the present invention. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present disclosure, and be protected by the following claims. Nothing in this section should be taken as a limitation on those claims. Further aspects and advantages are discussed below in conjunction with the embodiments.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0052]    In order to provide various functionality described herein,  FIG. 3  illustrates an example set of basic components of a flexible electronic visual display device  300  according to a first embodiment. In this example, the flexible electronic visual display device  302  features as components a flexible housing  304 , a flexible capacitive or resistive multi-touch display screen  306 , an image sensor or camera  308 , a three-dimensional depth sensor  310 , and dual-array microphones  312 ,  314  as information capture elements, and a control system  320 , to display a three-dimensional scene  360  on the display screen to a user attempting to create, maintain, and improve a perception of depth. 
         [0053]    The control system  320  includes an information processing circuit  322 , an information acquisition component  324 , a model acquisition component  326 , a type of physical processing circuit  328 , such as a programmable visual graphics processing unit (GPU) for example, and a drive circuit  330 . 
         [0054]    As would be apparent to one of ordinary skill in the art, the display device can include many types of display screen layer elements such as a touch screen, three-dimensional display device, multi-layer display device, liquid crystal display (LCD) device, organic light emitting diode (OLED) display device, quantum dot based light emitting diode (QLED) display device, electronic paper display device, or interferometric modulator display (IMOD) device. 
         [0055]    In the case of an image sensor, a sensor information capture element can include, or be based at least in part upon any appropriate technology, such as a CCD or CMOS image capture element having a determined resolution, focal range, viewable area, and capture rate. Such image capture elements can also include at least one IR sensor or detector operable to capture image information for use in determining motions of the user. It should be understood, however, that there can be fewer or additional elements of similar or alternative types in other embodiments, and that there can be combinations of display screen layer elements and contactless sensors, and other such elements used with various devices. 
         [0056]    In this example, the image sensor  308 , the three-dimensional depth sensor  310 , or both sensors together can track a feature of the user, such as the user&#39;s head  350 , or eye  352 , and provide the captured sensor information to the information processing circuit  322  of the control system  320 . The information processing circuit determines the location and movement of the user&#39;s feature with respect to the display device, and provides the determined information about the position and motion of the user&#39;s feature to the information acquisition component  324  of the control system. 
         [0057]    On the basis of the three-dimensional model of the scene and additional related information provided by the model acquisition component  326 , the position and motion information provided by the information acquisition component  324 , and/or the applied method for creating a perception of depth, the physical processing circuit  328  used in this case as a visual processing circuit performs the viewing transformation, including camera transformation and projection transformation, in correspondence with the change of the user&#39;s viewpoint and viewing angle on the displayed three-dimensional scene  360 , performs the window-to-viewport transformation, synthesizes the two-dimensional raster representations for the display screen  306  of the flexible electronic visual display device, and provides the raster representations to the drive circuit  320 . The drive circuit transfers the two-dimensional raster representations of the scene to the display screen. Methods to create a perception of depth are well known in the art and will not be discussed herein in detail. 
         [0058]    Furthermore, the image sensor  308 , the three-dimensional depth sensor  310 , or both sensors together can also recognize an object  362  put on the horizontal surface of the display device, and again provide the captured sensor information to the information processing circuit  322  of the control system  320 . The information processing circuit determines the location of the object with respect to the display device and the objects shape, and provides the determined information about the position and shape of the object to the information acquisition component  324  of the control system for further processing by a suitable type of physical processing circuit  328  and further use, as it would be apparent to somebody skilled in the art and therefor is not discussed further within this disclosure. 
         [0059]    In addition, the dual-array microphones  312 ,  314  can capture voice commands of the user and again provide the captured sensor information to the information processing circuit  322  of the control system  320  for further processing and use. The example display device can also include at least one motion component  332 , such as an electronic gyroscope, kinds of inertial sensors, or an inertial measurement unit, connected to the information processing circuit  322  of the control system  320  to determine motion of the display device arranged in a portable variant discussed eleswhere herein for assistance in location and movement information or/and user input determination. 
         [0060]    Movement and gesture recognition approaches, as well as navigation approaches used for multi-dimensional input, as described in the U.S. Pat. No. 8,788,977, issued Jul. 22, 2014, and entitled “Movement Recognition as Input Mechanism”, the U.S. Pat. No. 8,891,868, issued Nov. 18, 2014, and entitled “Recognizing gestures captured by video”, the U.S. patent publication No. 2013/0222246, publicated Aug. 29, 2013 and entitled “Navigation Approaches for Multi-Dimensional Input”, and the U.S. Pat. No. 8,933,876, issued Jan. 13, 2015, and entitled “Three-Dimensional User Interface Session Control”, which are hereby incorporated herein by reference, can be applied advantageously. 
         [0061]    Moreover, it is to be understood that any person skilled in the art should be able to construct a flexible electronic visual display device that provides a multi-modal user interface to the user by combining and integrating the various information capture elements and related control systems and control methods. In the same respect, it should be possible without any problems to integrate a wireless electric power link device within the horizontal surface, which is configured to wirelessly receive electric power from an external power supply, and a wireless charging means, which is configured to supply other electrically operated devices layed on the horizontal surface with electric power. 
         [0062]      FIG. 4  illustrates an example set of basic components of a flexible electronic visual display device  400  according to a second embodiment. In this example, the flexible electronic visual display device  402  has a flexible housing  404 , a flexible multi-touch display screen  406 , four information capture elements  408 ,  410 ,  412 ,  414  positioned at various locations on the same side of the device as the display screen  406 , a projector device  416 , and a control system  420  enabling the display device to capture sensor information about a user of the device during typical operation where the user is at least partially in front of the flexible electronic visual display device, and to project images on the display screen or/and on an arbitrary object  462  put on the horizontal surface of the electronic device. 
         [0063]    The control system  420  includes an information processing circuit  422 , an information acquisition component  424 , a model acquisition component  426 , a type of physical processing circuit  428 , such as a programmable visual graphics processing unit (GPU) for example, and a drive circuit  430 . 
         [0064]    In this example, the four image sensors  408 ,  410 ,  412 ,  414  can act alone, in pairs, in groups, or all together, and track a feature of the user, such as the user&#39;s head  450 , or eye  452 , or/and recognize the object  462  put on the horizontal surface of the display device, and provide the captured sensor information to the information processing circuit  422  of the control system  420 . The information processing circuit determines the location and movement of the user&#39;s feature or/and the position and shape of the object with respect to the display device, and provides the determined information about the position and motion of the user&#39;s feature or/and the position and shape of the object to the information acquisition component  424  of the control system. 
         [0065]    On the basis of the three-dimensional model of the scene and additional related information provided by the model acquisition component  426 , and the position and motion information provided by the information acquisition component  424 , the physical processing circuit  428  performs the viewing transformation, including camera transformation and projection transformation, in correspondence with the change of the user&#39;s viewpoint and viewing angle on a displayed scene, performs the window-to-viewport transformation, synthesizes the two-dimensional raster representations for the display screen  406  or/and the projector device  416  of the flexible electronic visual display device, and provides the raster representations to the drive circuit  420 . The drive circuit transfers the two-dimensional raster representations of the scene to the display screen or/and the projector device. Methods to project informations on a surface, augment arbitrary objects with additional informations, and mix the outputs of a display device and a projector device are well known in the art and will not be discussed herein in detail. 
         [0066]      FIG. 5  illustrates an example set of basic components of a flexible electronic visual display device  500  according to a third embodiment. In this example, the flexible electronic visual display device  502  has a flexible housing  504 , a flexible multi-touch display screen  506 , four information capture elements  508 ,  510 ,  512 ,  514  positioned at various locations on the same side of the device as the display screen  506 , a three-dimensional scanner device  518 , and a control system  520  enabling the display device to capture sensor information and to scan and digitalize an arbitrary object  562  put on the horizontal surface of the electronic device. 
         [0067]    The control system  520  includes an information processing circuit  522 , an information acquisition component  524 , a model acquisition component  526 , a type of physical processing circuit  528 , and a drive circuit  530 . The four image sensors  508 ,  510 ,  512 ,  514  and the control system  520  work together in the same way as described in relation with the second embodiment illustrated in  FIG. 4 , so that a detailed description can be obmitted here. 
         [0068]    In addition in this example, the three-dimensional scanner device  518  recognizes and scans the object  562  put on the horizontal surface of the display device, and provide the captured information to the information processing circuit  522  of the control system  520 . The information processing circuit determines the location of the object with respect to the display device and the object&#39;s shape, and provides the determined information about the position and shape of the object to the information acquisition component  324  of the control system for further processing by a suitable type of physical processing circuit  528 . 
         [0069]    On the basis of the information about the scanned object and additional related information provided by the model acquisition component  526 , and the position information provided by the information acquisition component  524 , the physical processing circuit  528  constructs a digital three-dimensional model of the object. The drive circuit  530  transfers the three-dimensional representations of the scanned object to other electronic devices connected with the control system  520  for further processing, as it would be apparent to somebody skilled in the art and therefor well known methods to scan and digitalize objects and mixing the outputs of a display device and a scanner device are not discussed further within this disclosure. 
         [0070]      FIGS. 6A ,  6 B, and  6 C illustrate a flexible electronic visual display device  602  with an adjustable means or stand for a flexible housing  604 , which comprises a base  606  mechanically connected to the horizontal part of the housing, an adjustment member  608  mechanically connected to the vertical part of the housing, and a supporting means  610  sliding through the housing and the adjustment member. The base  606  and the supporting means  610  are pivotably connected by a rotary axis  612 . It should be noted here that any person skilled in the art should be able to construct similar or other adjustable supporting means in various variants, which even can comprise an electric actuator for moving the supporting means, and that the shown adjustable supporting means is only meant as a non-limiting example. 
         [0071]      FIG. 6A  shows the display device in a first configuration  600  with the vertical surface standing upright.  FIG. 6B  shows the display device in a second configuration  620  with the vertical surface titled. As it can also be seen in the  FIG. 6B  the supporting means  608  slided through the housing and the member  610  towards the upper side of the display device.  FIG. 6C  shows the display device in a third configuration  640  with the base  606  and means  608  completely included within the housing and the vertical and horizontal surfaces laid out flat. 
         [0072]      FIG. 7A ,  7 B, and  7 C illustrate an example portable computing device with a flexible electronic visual display device  702  that can be used to provide functions and perform methods in accordance with various embodiments discussed and suggested herein. In this example, the portable flexible computing device has a housing comprising two segments  704 ,  705 , bellows-like joint means  718 ,  719  mechanically connecting the segments  704 ,  705  with each other, a display screen  706 , four information capture elements  708 ,  710 ,  712 ,  714  positioned at various locations on the same side of the portable flexible computing device as the display screen  706 , and integrated dual-array microphones and speakers  716 ,  717  enabling the portable flexible computing device to capture sensor information about a user of the electronic device during typical operation where the user is at least partially in front of the flexible electronic visual display screen, and to reproduce sound.  FIG. 7A  shows the portable flexible computing device in the flat laid out configuration  700  from the top,  FIG. 7C  shows a portion of the portable flexible computing device in the laid out flat configuration  720  from the side, and  FIG. 7B  shows the device in the folded configuration  740  from the side. 
         [0073]    In this example, each capture element is a camera capable of capturing image information over a visible or/and infrared (IR) spectrum, and in at least some embodiments can select between visible and IR operational modes. It should be understood, however, that there can be fewer or additional elements of similar or alternative types in other embodiments, and that there can be combinations of cameras, infrared detectors, sensors, and other such elements used with various devices. The device can also have a material and/or components that enable a user to provide input to the device by applying pressure at one or more locations. The device housing segments  704 ,  705  can also include touch-sensitive material that enables a user to provide input by sliding a finger or other object along a portion of the housing. Various other elements and combinations of elements can be used as well within the scope of the various embodiments as should be apparent in light of the teachings and suggestions contained herein. 
         [0074]    Not shown for better illustration are an electronic module comprising at least one integrated circuitry for processing arbitrary information and a data memory for storing arbitrary data, a wireless communication interface device connected with the electronic module, and an electric energy storage device for providing the portable flexible computing device with electric power. A similar computing device can be found, for example, in the U.S. patent publication No. 2013/0222246, publicated Aug. 29, 2013 and entitled “Navigation Approaches for Multi-Dimensional Input”, which is already incorporated herein by reference. 
         [0075]    In order to provide various functionality described herein,  FIG. 8  illustrates an example set of basic components of a computing device  800  with a flexible electronic visual display device, such as the flexible computing device  700  described with respect to  FIGS. 7A ,  7 B, and  7 C. 
         [0076]    In this example, the flexible computing device includes at least one central processor  802  for executing instructions that can be stored in at least one memory device or element  804 . As would be apparent to one of ordinary skill in the art, the computing device can include many types of memory, data storage or non-transitory computer-readable storage media, such as a first data storage for program instructions for execution by the processor  802 , the same or separate storage can be used for images, sounds, or data, a removable storage memory can be available for sharing information with other computing devices, etc. The computing device can also include a flexible display device  806  of various types as discussed elsewhere herein, and also might convey information via other means, such as through a projector device, audio speakers, or vibrators. 
         [0077]    As discussed, the flexible computing device with a flexible electronic visual display device  806  in many embodiments includes at least one sensor information capture element  808 , such as one or more cameras that are able to image a user of the computing device, or a three-dimensional depth sensor and three-dimensional scanner device that are able to scan an arbitrary object. The example computing device includes at least one motion component  810 , such as one or more electronic gyroscopes or/and inertial sensors discussed elsewhere herein, used to determine motion of the computing device for assistance in information or/and input determination for controlling the hardware based functions, specifically the flexible display device  806  and other visual output devices, and also the software based functions. The computing device also can include at least one illumination element  812 , as may include one or more light sources (e.g., white light LEDs, IR emitters, or flashlamps) for providing illumination and/or one or more light sensors or detectors for detecting ambient light or intensity, etc. 
         [0078]    The example computing device can include at least one additional input device able to receive conventional input from a user. This conventional input can include, for example, a push button, touch pad, touch screen, wheel, joystick, keypad, mouse, trackball, keypad or any other such device or element whereby a user can input a command to the device. These input/output (I/O) devices could even be connected by a wireless infrared or other wireless link, or a wired link as well in some embodiments. In some embodiments, however, such a computing device might not include any buttons at all and might be controlled only through a combination of visual (e.g., gesture) and audio (e.g., spoken) commands such that a user can control the device without having to be in contact with the computing device. 
         [0079]    The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense. It will, however, be evident that various modifications and changes may be made thereunto by those skilled in the art without departing from the broader spirit and scope of the invention as set forth in the claims. In other words, although embodiments have been described with reference to a number of illustrative embodiments thereof, this disclosure is not limited to those. Accordingly, in various embodiments of the invention the various embodiments of the information capture components and output devices of the flexible electronic visual display device discussed and suggested in  FIGS. 3 ,  4 ,  5 ,  6 A,  6 B, and  6 C, and and  7 A,  7 B, and  7 C can be combined with each other in appropriate ways. The scope of the present disclosure shall be determined only by the appended claims and their equivalents. In addition, variations and modifications in the component parts, arrangements, or/and alternative uses must be regarded as included in the appended claims.
