[0015] In the following detailed description, reference is made to the accompanying drawings which form a part of the detailed description, and in the drawings, specific embodiments in which the subject matter of the present invention may be practiced are shown by way of illustration. The embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, and it should be understood that other embodiments may be utilized and structural, logical, and electrical changes may be made without departing from the scope of the subject matter of the present invention. These embodiments of the subject matter of the present invention may be referred to herein individually and / or collectively by the term "invention", merely for convenience, and are not intended to voluntarily limit the scope of the present application to any single invention or inventive concept in the event that more than one invention or inventive concept is actually disclosed.

[0016] Accordingly, the following description should not be construed as restrictive, and the scope of the subject matter of the present invention is defined by the appended claims and their equivalents.

[0017] In the following embodiments, the same components are denoted by the same reference numerals.

[0018] In the following embodiments, the term data storage or memory is intended to cover any computer-readable storage medium and / or device (or a collection of data storage media and / or devices). Examples of data storage include, but are not limited to, optical discs (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 the like.

[0019] In one embodiment, the functions or algorithms described herein are implemented in hardware, software, or a combination of software and hardware. The software includes computer-executable instructions stored on a computer-readable carrier medium such as a memory or other type of storage device. Additionally, the functions described may correspond to modules, which may be software, hardware, firmware, or any combination thereof. Multiple functions are performed in one or more modules as needed, and the embodiments described are merely examples. The software is executed on a digital signal processor, an ASIC, a microprocessor, or other type of processor.

[0020] Some embodiments implement functions in two or more specific interconnected hardware modules or devices, where the relevant control and data signals are transferred between and through the modules, or as part of an application specific integrated circuit. Accordingly, the exemplary processing flows may be applied to software, firmware, and hardware implementations.

[0021] A general embodiment provides a display device, including: a display screen for displaying information; a memory for storing information to be displayed on the display screen; a motion detection device for detecting the motion of the display device; and a processor programmed to control the display of information on the display screen and, in response to the motion detected by the motion detection device, control the display screen to erase at least a portion of the information displayed on the display screen, wherein the motion detection device is configured to detect multiple motion types, and the processor is programmed to identify the detected motion type and selectively erase the information displayed on the display screen according to the identified motion type.

[0022] The present invention is applicable to portable display devices, but is not limited thereto. The display device can be applied to any display device capable of moving in a reciprocating, rotating or shaking motion. Such display devices are typically portable and wireless, but can simply be moved and connected by a wire. The display device can be part of another device and is thus removable in use to allow the user to perform a shaking, rotating or reciprocating motion to erase the displayed information. The display can be rigid or flexible. The display can be detachable. There can be more than one display, and the displays can be of different types, for example, one flexible and one rigid.

[0023] In one example, in response to a shaking or reciprocating motion greater than a threshold detected by the motion detection device, at least a portion of the information displayed on the display screen is erased. This avoids inadvertently erasing the displayed information due to the shaking of the display device, for example, when traveling in a vehicle, train or airplane. Erasing of the information may require a more forceful motion to initiate the erasing.

[0024] In one example, at least for the set of information being displayed, erasing the displayed information also causes the information to be erased or deleted in the memory, such that the action is equivalent to the delete key on a keyboard (although the information may still reside in the memory to allow cancellation of the erase operation).

[0025] Motion can be detected in multiple directions, and the direction of the shaking or reciprocating motion can be detected to selectively erase the information displayed on the display screen.

[0026] The device can be programmed, or the user can select, such that certain motion directions of the display device or certain types of motion of the display device, such as different motion patterns, can result in different erase operations. For example, different erase operations can involve erase operations in different screen areas, such as boxes on a web page or input areas in an application being executed on the display device, or involve erasing of different types of display information. For example, one type of motion or motion in different directions can result in erasing of a displayed image, erasing of typed text, erasing of handwritten text, erasing of a table or spreadsheet, etc.

[0027] The types of motion that a user can use for an erase operation can include a shake or reciprocating motion of a display device, for example, it can be any one of a linear motion, a reciprocating motion, a rotational motion, a rocking motion, a seesaw motion, a swaying motion, or a rocking motion. The displacement or amplitude of the "shake", the frequency or rate of the "shake", and / or the speed or strength of the "shake" can also be components of the type of motion of the display device. The motion can include a complex mixture or aggregation of motions or types of motion, for example, a rotation with a shake at the same time, or a sequence of motions, such as a rotation after a shake, or a rotation in one direction followed by a rotation in another direction. Thus, the sequence of motions can be a sequence of the same type of motion or different types of motion.

[0028] The display device can be programmed to allow a user to teach it the type of motion and to allow an erase operation to be performed in response to the detected type of motion. For example, the display device can display an erase option during a learning or startup phase while requesting the user to initiate the desired type of motion to be used for that erase operation. The user may be required to perform the operation several times so that the processor can implement a learning process to learn and store the type of motion corresponding to the selected erase operation. The type of motion and the erase operation can be learned for an individual user. For example, the user can enter their name or signature to use the display device, and the learned type of motion and erase operation are then stored for use by the user when they enter their name or signature.

[0029] In one example, the display device can include an input device for receiving input for displaying information. The input device can include a touch-sensitive display and / or a pen. The pen allows the user to input handwritten text and graphics.

[0030] One aspect provides a carrier medium, such as a non-transitory storage medium storing code executed by a processor of a machine to implement the method, or a transitory medium carrying processor-executable code executed by a processor of a machine to implement the method. Embodiments can be implemented in programmable digital logic implementing computer code. The code can be provided to the programmable logic, such as a processor or a microprocessor, on a carrier medium. One such embodiment of the carrier medium is a transitory medium, that is, a signal such as an electrical, electromagnetic, acoustic, magnetic, or optical signal. Another form of the carrier medium is a non-transitory storage medium storing the code, such as a solid-state memory, a magnetic medium (hard disk drive), or an optical medium (compact disc (CD) or digital versatile disc (DVD)).

[0031] In one example, the display device may be used as the display unit in any example of the display device disclosed in the co-pending application GB1722249.8 filed on December 29, 2017, the content of which is incorporated herein by reference in its entirety, or the display device may be used as the device disclosed in the co-pending UK patent application entitled "Device Operation Control" filed on the same date as this application, the content of which is incorporated herein by reference in its entirety.

[0032] Specific embodiments will now be described with reference to the accompanying drawings.

[0033] Figure 1 is a schematic diagram showing the display device.

[0034] The display device 2 includes a display screen 1 capable of displaying information. In this example, the display screen displays three types of information, namely typed text 11, handwritten text 41, and an image 31. The information can be displayed by any application executed on the device, such as a web browser, an email application, a word processor, a spreadsheet, an image editor, etc. The displayed information can be, for example, a document or form having areas to be completed or filled in, such as the address area and name area in a standard form letter or fields in a form. A pen device 50 can be used to input handwritten text. 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 position and thus generate the input handwritten text 41. The display screen 1 can be touch-sensitive to allow, for example, the input of information and commands to the display device through touch-sensitive options and / or the displayed keyboard.

[0035] The direction of movement that the display device can experience is shown below the display device as a method of erasing the displayed information. The movement can be a linear or reciprocating movement in any one of three directions along three axes x, y, and z in three dimensions as shown by the cross arrows. Additionally or alternatively, the movement can be non-linear, curved, or rotational, as shown by the curved arrows.

[0036] In Figure 1 example, the movement of the display device can erase all the displayed information or a selected portion, such as one or more of the typed text 11, handwritten text 41, or image 31.

[0037] Figure 2 An alternative display screen 20 of the display device is shown. In this example, there are three different display areas, namely, a typed text display area 10 having the displayed typed text 11, an image display area 30 displaying the image 31, and a handwritten text display area 40 displaying the handwritten text 41 created using the pen 50.

[0038] The movement of the display device in this example can be a linear or reciprocating back-and-forth movement in any one of three directions along three axes x, y, and z in three dimensions as shown by the cross arrows in Figure 1 . Additionally or alternatively, the movement can be non-linear, curved, or rotational, as shown by the curved arrows in Figure 1 .

[0039] In the example of Figure 2 , the movement of the display device can erase all the displayed information or selective portions, such as the information in one or more of display regions 10, 30, and 40.

[0040] Although different types of information are shown and described as being displayed in different display regions in Figure 2 , different display regions can display the same type of information or any combination of information types. Additionally, the display regions can display a mixed type of information. Figure 2 The example of

[0041] is for illustrative purposes only. Figure 1 Thus, the type of movement detected by the movement detection device of the display device can detect any one of a variety of types of movement patterns in any dimension or direction. Examples of different movement patterns are: back-and-forth rocking, left-and-right rocking, up-and-down rocking, left-and-right rotation (tilting left and right), up-and-down rotation (tilting up and down), and rotation. Each of these movement patterns represents a lateral (rocking) or rotational movement along or around one of the three axes shown in

[0042] . Two types of each of these movement types can be detected based on the starting movement. For example, back-and-forth can be from back to front or from front to back, left-and-right can be from left to right or from right to left, rotation can be clockwise or counterclockwise rotation, etc.

[0043] The memory of the display device can store a set of erase commands to be implemented by the processor for each type of movement detected by the movement detection device and identified by the processor from the signals from the movement detection device. These commands can be predefined, downloaded from a data source, or they can be user-defined.

[0044] Figure 3 It is a flowchart showing the learning stage of a display device.

[0045] In step S1, the display device enters the learning stage. This can be automatic when the display device starts up, or as a result of some other operation of the display device, or it can be the result of a user selection, i.e., using an input, such as using an input device of the display device. In step S2, the display of the display device shows a menu defining control operations, and the user can use an action as user input to select to perform the control operation. The displayed menu can simply be, for example, a list or a drop-down menu. The list can be organized into categories of erase operation types, for example, erase one letter, erase one word, erase text, erase all text in a display area or frame, erase an image, erase displayed historical data, erase a frame or a display area, etc.

[0046] In step S3, a user selection of an erase operation menu item is received, and then in step S4, the display device waits for a motion detector device (e.g., an accelerometer) to detect the motion of the display device. The motion is recorded within a short time period suitable for capturing the motion pattern (e.g., 1 to 2 seconds). To improve the accuracy of the matching process and allow for variations in the user's motion pattern, in step S5, the process loops back to ask the user to repeat the motion input a number (N) of times, for example, any number from 3 to 10 times. More iterations improve the accuracy of the matching process, but reduce the usability of the display device: the user will lose patience because the motion pattern needs to be repeated too many times.

[0047] At the end of the loop-back process, in step S6, the recorded repeated motion patterns are averaged, and in step S7, the average is used and stored as part of the information about the motion type in the stored motion type erase data. Data indicating the degree of deviation between the recorded motion patterns can also be stored as part of the motion type data to assist the matching process during the operation stage, i.e., to assist in evaluating whether the match is within the expected deviation of the stored average motion pattern. The identifier identifying the corresponding erase operation is also stored as part of the stored motion type erase data.

[0048] Then, the process returns to step S2 to allow the user to select another erase operation from the menu. If the user has finished selecting erase operations, the user can choose to exit the learning stage.

[0049] Figure 4 It is a flowchart showing the operation stage of the display device after the learning stage.

[0050] In step S10, the display device enters the operation stage, and in step S11, information is displayed on the display screen. The information can be displayed in different areas, such as Figure 1 andFigure 2 The frame or window shown. The information displayed can also be of different information types, such as text or images. The movement of the display device is detected in step S12. In step S13, the pattern of the movement is compared with the pattern of the movement type in the stored movement type erasure data to determine whether the movement matches the movement type. If no match is found (step S14), the process returns to step S12 to detect further movement. If a match with the movement data of the matching type is found in step S14, the corresponding erasure operation is identified in the movement type erasure data in step S15, and the erasure operation is performed in step S16. The matching erasure operation can be an operation to erase the information in one of the erasure areas or an operation to erase the information type such as text or images. Then, the process returns to step S12 to detect the next movement of the device for further control operations.

[0051] In Figure 4 , the average value of the movement data of multiple recorded movement operations is taken. However, the present invention is not limited to taking an average, and only one movement detection can be used, or a number can be recorded and they can be stored separately so as to be separately matched with the movement pattern during the operation phase.

[0052] In Figure 4 , a menu is presented to the user to select an erasure operation, thereby teaching the display device the movement type for the erasure operation. The user is also able to define their own erasure operations using the user input device. In addition, the display device can automatically enter the learning phase, for example, at startup, and request the user to input a sequence of movement types for controlling the operation sequence. The movement types and erasure operations can be learned for individual users. For example, the user can input their name or signature to use the display device, and the learned movement types and erasure operations are then stored for use by the user when they input their name or signature.

[0053] Figure 5 is a schematic diagram showing the electronic components of an example display device.

[0054] The processor 100 is connected to a static or non-volatile memory 102, which stores the code used by the processor 100, such as the operating system code, and is used to store the data and information to be displayed in a non-volatile manner. A volatile memory 103 is provided for storing the application code implemented by the processor 100 and the data and information for display and erasure control. The volatile memory can store code (e.g., code modules), which includes code for identifying the movement pattern detected by the movement sensor 104, and code (e.g., code modules) for controlling the display screen 105 in response to erasing the displayed information.

[0055] The display screen 105 is connected to the processor 100 for displaying information. The display screen 105 may include a touch-sensitive display to provide an input device. The pen 50 ( Figure 1 shown in) may be used with the display screen 105 to allow input of handwritten text or drawings. The camera 106 may also optionally be connected to the processor 100 to capture images. The camera 106 may also be used as an input device for inputting information and commands using gesture recognition implemented by the processor on the images captured by the camera 106.

[0056] The network connector 101 is connected to the processor 100 for communicating with a communication or computer network. This communication link may transfer data, information, and control between the display device and other display devices or computers over the network. The network connector 101 may be connected to the communication or computer network using a wired or wireless connection. For example, the wired connection may be an Ethernet connection to a LAN or a telephone connection, such that the network connector 101 acts as a modem or router. The wireless connection may be WIFI, WiMAX, CDMA, GSM, GPRS, wireless local loop, or WAN. For low-range and low-power wireless communication, Bluetooth may be used.

[0057] The motion sensor 104 is connected to the processor 100 to detect the motion of the display device. The motion sensor 104 may include any conventional motion sensor, such as an accelerometer. The motion sensor 104 is capable of detecting the motion of the display device in any direction, i.e., it is a multi-axis motion sensor to detect motion along any one of three orthogonal axes in three dimensions.

[0058] In any of the above examples, the display device may have display screens on both sides, so that the display device can be flipped to view information on both sides. The erase operation may be applied to both sides or only to one side. In one example, this may be selectively set. The display or displays may also be removed from the mounting frame.

[0059] In one or more embodiments, the display device may include a docking portion or mount, and the display screen is mounted to the docking portion or mount in a detachable or removable manner, such that the display screen can be used separately from the mount. The mount and the display screen may communicate with each other using a wireless link, such that the mount may contain some components of the display device, such as the processor and memory, while the display screen may only contain those components necessary to operate the display screen, detect the motion of the display screen, and communicate with the processor. In one embodiment, more than one display screen may be provided that is detachable from the mount, where each display screen operates independently to provide an erase operation by using motion detection of a shared processor in the mount.

[0060] The display device may include one or more speakers for audio output and one or more microphones for audio input. In addition, the display device may be connected to peripheral devices such as a keyboard and / or a pointing device by a wired or wireless connection to allow input of information and commands to the display device.

[0061] In any of the above examples, the display device may include other input devices such as a keyboard, a pointing device (e.g., a mouse), or a touch screen to enable a user to input controls and information in combination with a motion detection control input method. The input device may also be used to perform conventional erasure operations to complement the motion erasure capabilities of the display device, such as keyboard deletion, text selection, and deletion operations of the display, etc. In addition, a camera may be provided to allow image capture, enabling gesture input as a method of control or information input.

[0062] In an embodiment, in addition to or as an alternative to motion control input, a camera may be provided in the device to capture video in a user-facing direction such that the user can use gestures to control the erasure of information displayed on the display screen according to the type of recognized gesture. Gesture control may include recognizing the movement of a user's body part (i.e., hand, facial feature, or overall body position), or recognizing an object moved by the user, such as a stick, a ruler, or something worn by the user. Pattern recognition techniques may be used to recognize the type of gesture and identify them. Example gesture types may include a sweep of the hand to the left or right, or up or down, or a wave of the hand.

[0063] In the case of providing gesture control in combination with motion control, for example, in a situation where the user cannot pick up the display device, such as when their hands are wet or dirty, gesture control can be used for erasure operations. In addition, the display screen may be controlled to respond to the detected gesture type, recognize a comparable or associated motion type that controls the same erasure operation, and control the display screen to mimic the motion equivalent command of the gesture command. For example, if the motion command to erase text in a display area is a rotation from left to right, when an equivalent or associated gesture command such as waving a hand from left to right is recognized, the display screen may cause the display to rotate from left to right to return a confirmation to the user that the gesture command has been recognized as a motion command.

[0064] In one aspect, the present invention provides gesture control instead of motion control. In this aspect, a display device may: include a display screen for displaying information; a memory for storing information to be displayed on the display screen; gesture detection means (e.g., a camera and recognition software) for detecting gestures; and a processor programmed to control the display of information on the display screen and, in response to gestures detected by the gesture detection means, control the display screen to erase at least a portion of the information displayed on the display screen, wherein the gesture detection means is configured to sense multiple gesture types, and the processor is programmed to identify the sensed gesture types and selectively erase the information displayed on the display screen according to the identified gesture types. Thus, in this aspect, gesture recognition operates in the same manner as motion detection, and thus, in the motion detection examples described above, in this aspect, motion can be replaced by gestures.

[0065] In this aspect, the display device may be mobile or fixed / attached. A camera may be provided in the device to capture video in a user-facing direction such that the user can use gestures to control the erasure of the information displayed on the display screen according to the type of the recognized gesture. Gesture control may include recognizing the movement of a user's body part (i.e., hand, facial feature, or whole body position). Pattern recognition techniques can be used to identify the types of gestures and identify them. Example gesture types may include a hand swiping left or right, or up or down, or a hand waving.

[0066] Those skilled in the art will readily understand that various other changes may be made to the details, materials, and arrangements of the components and method steps that have been described and illustrated for the purpose of explaining the nature of the subject matter of the present invention without departing from the principles and scope of the subject matter of the present invention as expressed in the appended claims.
