[0006] Figure 2 is a schematic diagram illustrating an alternative display of an example display apparatus; and [0007] Figure 3 is a schematic diagram illustrating the electronic components of an example display apparatus.
Detailed Description [0008] In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments in which the inventive subject matter may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice them, and it is to be understood that other embodiments may be utilized, and that structural, logical, and electrical changes may be made without departing from the scope of the inventive subject matter. Such embodiments of the inventive subject matter may be referred to, individually and/or collectively, herein by the term “invention” merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed.
[0009] The following description is, therefore, not to be taken in a limited sense, and the scope of the inventive subject matter is defined by the appended claims and their equivalents.
[0010] In the following embodiments, like components are labelled with like reference numerals.
[0011] In the following embodiments, the term data store or memory is intended to encompass any computer readable storage medium and/or device (or collection of data storage mediums and/or devices). Examples of data stores include, but are not limited to, optical disks (e.g., CD-ROM, DVD-ROM, etc.), magnetic disks (e.g., hard disks, floppy disks, etc.), memory circuits (e.g., solid state drives, random-access memory (RAM), etc.), and/or the like. [0012] The functions or algorithms described herein are implemented in hardware, software or a combination of software and hardware in one embodiment. The software comprises computer executable instructions stored on computer readable carrier media such as memory or other type of storage devices. Further, described functions may correspond to modules, which may be software, hardware, firmware, or any combination thereof. Multiple functions are performed in one or more modules as desired, and the embodiments described are merely examples. The software is executed on a digital signal processor, ASIC, microprocessor, or other type of processor.
[0013] Some embodiments implement the functions in two or more specific interconnected hardware modules or devices with related control and data signals communicated between and through the modules, or as portions of an application-specific integrated circuit. Thus, the exemplary process flow is applicable to software, firmware, and hardware implementations.
[0014] A generalized embodiment provides a display apparatus comprising a display screen to display information; a memory to store information for display on the display screen; a motion detecting arrangement to detect motion of the display apparatus; and a processor programmed to control the display of the information on the display screen and responsive to motion detected by the motion detecting arrangement, to control the display screen to erase at least a part of the information displayed on the display screen, wherein the motion detecting arrangement is configured to detect a plurality of motion types, and the processor is programmed to identify the detected motion types and to selectively erase information displayed on the display screen in dependence upon the identified motion types.
[0015] The invention is suited to portable display apparatus but is not limited to such. The display apparatus is applicable to any display apparatus that can be moved in a reciprocal, rotational or shaking motion. Such a display apparatus is typically portable and wireless but could be simply moveable and connected by wires. The display apparatus could be part of another apparatus and removeable therefore in use to allow for the shaking, rotating or reciprocating motion to be effected by a user to erase displayed information. The display could be rigid or flexible. The display may be detachable. There could be more than one display and the displays can be of different types, e.g. one flexible and one rigid.
[0016] In one example, at least a part of the information displayed on the display screen is erased in response to shaking or reciprocating motion detected by the motion detecting arrangement that is greater than a threshold. This avoids unintentional erasing of displayed information due to a jolt of the display apparatus, for example while travelling in a car, train or airplane. The erasing of information can require more vigorous movement to initiate the erasing.
[0017] In one example, the erasing of the displayed information also causes the information to be erased or deleted in memory at least for the set of information being displayed, so that the action is equivalent to a delete key on a keyboard (although the information may still be resident in memory to allow an unerase operation).
[0018] The motion may be detected in multiple directions, and a direction of the shaking or reciprocating motion can be detected to selectively erase information displayed on the display screen.
[0019] The apparatus can be programmed, or the user can select, so that certain directions of motion of the display apparatus or certain types of motion of the display apparatus, such as different patterns of motion, can cause different erase operations. For example, the different erase operations can relate to erase operations in different screen regions, such as frames on a web page or input regions in an application executing on the display apparatus, or to the erasing of different displayed information types. For example, one type of motion or a different direction of motion may cause the erasing of a displayed image, another the erasing of typed text, another the erasing of handwritten text, another the erasing of a table or spreadsheet, etc.
[0020] Types of motion that the user can use for erase operations can comprise the shaking or reciprocating motion of the display apparatus can be any of a rectilinear, motion, a reciprocating motion, a rotational motion, swaying motion, see-sawing motion, swinging motion or rocking motion for example. The displacement or amplitude of the ‘shake’, the frequency or rate of the ‘shake’ and/or the velocity or vigour or the ‘shake’ can also be components of the type of motion of the display apparatus. The motion can comprise a complex mix or aggregation of motions or motion types e.g. a rotation simultaneously with a shake, or a sequence of motions e.g. a shake followed by a rotation, or a rotation in one direction followed by a rotation in another direction. The sequence of motions can hence be a sequence of the same motion types or different motion types.
[0021] The display apparatus can be programmed to allow the user to teach it motion types and erase operations to implement in response to the detected motion type. For example, the display apparatus may display erase options in a learning or startup phase, with the request to the user to initiate a desired motion type to be used for that erase operation. The user may be required to perform the operation a few times for the processor to implement a learning process to learn and store the motion type corresponding to a selected erase operation.
[0022] The display apparatus in one example can include an input arrangement to receive an input for the display of information. The input arrangement can comprise a touch sensitive display and/or a pen. A pen allows a user to input handwritten text and drawings.
[0023] One aspect provides a carrier medium, such as a non-transient storage medium storing code for execution by a processor of a machine to carry out the method, or a transient medium carrying processor executable code for execution by a processor of a machine to carry out the method. Embodiments can be implemented in programmable digital logic that implements computer code. The code can be supplied to the programmable logic, such as a processor or microprocessor, on a carrier medium. One such embodiment of a carrier medium is a transient medium i.e. a signal such as an electrical, electromagnetic, acoustic, magnetic, or optical signal. Another form of carrier medium is a non-transitory storage medium that stores the code, such as a solid-state memory, magnetic media (hard disk drive), or optical media (Compact disc (CD) or digital versatile disc (DVD)).
[0024] The display apparatus can, in one example, be used as the display unit in any of the examples of the display apparatus disclosed in co-pending application GB 1722249.8 filed on 29th December 2017, the contents of which is hereby incorporate by reference in its entirety or with the device disclosed in co-pending UK patent application entitled “Device Operation Control” filed on the same date as this application, the contents of which is hereby incorporate by reference in its entirety.
[0025] Specific embodiments will now be described with reference to the drawings.
[0026] Figure 1 is a schematic diagram illustrating a display apparatus.
[0027] The display apparatus 2 comprises a display screen 1 capable of displaying information. In this example, the display screen is displaying three types of information, namely typed text 11, handwritten text 41 and an image 31. The information can be displayed by any application executing on the apparatus, such as a web browser, email application, word processor, spreadsheet, image editor etc. The handwritten text can be input using a pen device 50. The screen display 1 can be sensitive to the proximity of the pen device 50 to detect the coordinates of the pen device 50 to track its location and hence to generate the input handwritten text 41. The display screen 1 can be touch sensitive to allow for input of information and commands to the display apparatus e.g. by the display of touch sensitive options and/or a keyboard.
[0028] Below the display apparatus is displayed the motion directions that the display apparatus can experience as a method of erasing displayed information. The motion can be a back and forth linear or reciprocating motion in any of three directions along three axes x, y and z in three dimensions as shown by the intersecting arrows. Also, or alternatively, the motion can be non-linear, curved or rotational as shown by the curved arrows.
[0029] In the example of figure 1, a motion of the display apparatus can erase all of the displayed information or selective parts, such as one or more of the typed text 11, the handwritten text 41 or the image 31.
[0030] Figure 2 illustrates an alternative display screen 20 of a display apparatus. In this example, there are three different display regions, namely a typed text display region 10 with displayed typed text 11, an image display region 30 displaying an image 31, and a handwritten text display region 40 displaying handwritten text 41, created using a pen 50.
[0031] The motion of the display apparatus of this example can be a back and forth linear or reciprocating motion in any of three directions along three axes x, y and z in three dimensions as shown by the intersecting arrows of figure 1. Also, or alternatively, the motion can be non-linear, curved or rotational as shown by the curved arrow in figure 1.
[0032] In the example of figure 2, a motion of the display apparatus can erase all of the displayed information or selective parts, such as information in one or more of the display regions 10, 30 and 40.
[0033] Although different types of information are illustrated and described as being displayed in the different display regions in figure 2, the different display regions could display the same information type or any combination of information types. Also, a display region could display a mix of information types. The example of figure 2 is just for illustration.
[0034] Hence, a motion type detected by a motion detecting arrangement of the display apparatus can detect any one of a plurality of types of patterns of motion in any dimension or direction. Examples of different patterns of motion are: shaking back and forth, shaking side to side, shaking up and down, turning side to side (tilting side to side), turning up and down (tilting up and down) and rotating. Each of these represents a lateral (shaking) or rotational movement along or about one of the three axes illustrated in figure 1. It is possible to detect two types of each of these motion types, based on the starting motion. For example, back and forth could be back and forth or forth and back, side to side could be left to right or right to left, rotating could be clockwise or anticlockwise rotating etc.
[0035] The memory of the display apparatus can store a set of erase commands to implement by the processor for each type of motion detected by the motion detecting arrangement and identified by the processor from the signal from the motion detecting arrangement. These commands can be predefined or downloaded from a data source or they can be user defined.
[0036] The display apparatus can be programmed to allow the user to teach it motion types and erase operations to implement in response to the detected motion type. For example, the display apparatus may display erase options in a learning or startup phase, with the request to the user to initiate a desired motion type to be used for that erase operation. The user may be required to perform the operation a few times for the processor to implement a learning process to learn and store the motion type corresponding to a selected erase operation. The display apparatus then stores a pattern of detected motion for each erase operation to be used in future motion detection operations for the execution of erase operations.
[0037] Figure 3 is a schematic diagram illustrating the electronic components of an example display apparatus.
[0038] A processor 100 is connected to static or non-volatile memory 102 storing code used by the processor 100, such as operating system code and for the storage of data and information for display in a non-volatile manner. Volatile memory 103 is provided for the storage of application code for implementation by the processor 100 and data and information for display. The volatile memory can store code (e.g. a code module) comprising code for identifying motion patterns detected by the motion sensor 104, and code (e.g. a code module) for controlling a display screen 105 in response to erase displayed information.
[0039] The display screen 105 is connected to the processor 100 for the display of information. The display screen 105 can comprise a touch sensitive display to provide an input arrangement. A pen 50 (shown in figure 1) can be used with the display screen 105 to allow for the input of freehand text or drawings. A camera 106 can also optionally be connected to the processor 100 to capture images. The camera 106 can also be used as an input arrangement for the input of information and commands using gesture recognition implemented by the processor on the images captured by the camera 106.
[0040] A network connector 101 is connected to the processor 100 for communication with a communications or computer network. This communication link can pass data, information and controls between the display apparatus and other display apparatuses or computers over the network. The network connector 101 can be connected to a communications or computer network using a wired or wireless connection. For example, a wired connection could be an ethernet connection to a LAN or a telephone connection, such that the network connector 101 acts as a modem or router. A wireless connection could be WIFI, WiMAX, CDMA, GSM, GPRS, wireless local loop or WAN. For low range and low power wireless communications, Bluetooth™ may be used.
[0041] A motion sensor 104 is connected to the processor 100 to detect motion of the display apparatus. The motion sensor 104 can comprise any conventional motion sensor, such as an accelerometer. The motion sensor 104 is capable of detecting motion of the display apparatus in any direction i.e. it is a multi-axis motion sensor to detect motion along any of three orthogonal axes in three dimensions.
[0042] In any of the examples above, the display apparatus may have a display screen on both sides, so that it can be turned over to view information on both sides. The erase operation could apply to both sides or to just one side. This, in one example, can be selectively set. The display or displays can also be detached from a mount frame.
[0043] The display apparatus can include one or more loudspeakers for audio output and one or more microphones for audio input. Also, the display apparatus can connect to a peripheral device such as a keyboard and/or pointing device by a wired or wireless connection to allow for input of information and commands to the display apparatus.
[0044] In any of the examples above, the display apparatus can include other input arrangements, such as a keyboard, pointer device (e.g. a mouse), or a touch screen, to enable a user to input controls and information in conjunction with the motion detection control input method. Also, a camera can be provided to allow image capture to enable gesture input as a method of control or information input.
[0045] In embodiments, in addition to or alternatively to the motion control input, a camera can be provided in the apparatus to capture video in a direction facing the user so that the user can use gestures to control the erasing of information displayed on the display screen in dependence upon the type of identified gesture. The gesture control can comprise the recognition of movements of a user’s body parts i.e. hands, facial features or the overall body position or the recognition of an object moved by the user, such as a stick, ruler or something worn by the user. Pattern recognition techniques can be used to recognize the type of gestures and to identify them. Example gesture types can include sweeping of a hand to the left or right, or up or down, or a waving of a hand.
[0046] Where the gesture control is provided in conjunction with the motion control, the gesture control erase operation can be used, for example, where the user is unable to pick up the display apparatus, e.g. they have wet or dirty hands. Further, the display screen can be controlled to be responsive to the detected gesture type and to identify a comparable or associated motion type that controls the same erase operation and to control the display screen to cause the display screen to mimic the motion equivalent command to the gesture command.
For example, if the motion command to erase text in a display region is a left to right rotation, when an equivalent or associated gesture command e.g. waving the hand from left to right, is identified, the display screen can cause the display to rotate from left to right to act as a confirmation back to the user that the gesture command has been recognized as the motion command.
[0047] In one aspect, the invention provides gesture control instead of motion control. In this aspect the display apparatus can comprise a display screen to display information; a memory to store information for display on the display screen; a gesture detecting arrangement to detect a gesture (e.g. a camera and recognition software); and a processor programmed to control the display of the information on the display screen and responsive to gesture detected by the gesture detecting arrangement, to control the display screen to erase at least a part of the information displayed on the display screen, wherein the gesture detecting arrangement is configured to sense a plurality of gesture types, and the processor is programmed to identify the sensed gesture types and to selectively erase information displayed on the display screen in dependence upon the identified gesture types. Hence, in this aspect, the gesture recognition operates in the same way as the motion detection and hence, in the motion detection examples described herein above, motion can be replaced with gesture in this aspect.
[0048] In this aspect, the display apparatus can be mobile or fixed/attached. A camera can be provided in the apparatus to capture video in a direction facing the user so that the user can use gestures to control the erasing of information displayed on the display screen in dependence upon the type of identified gesture. The gesture control can comprise the recognition of movements of a user’s body parts i.e. hands, facial features or the overall body position. Pattern recognition techniques can be used to recognize the type of gestures and to identify them. Example gesture types can include sweeping of a hand to the left or right, or up or down, or a waving of a hand.
