DETAILED DESCRIPTION
In general terms, the invention described in relation to the figures is a method of controlling a display device using a control device that is operable in at least two different modes of operation.
Referring to FIGS. 1A, 1B, 3A and 3B, there is illustrated a control device 30 (in the form of a handset controller) for controlling a display device 80 (such as a display of an in-flight entertainment (IFE) system) adapted to display content (such as a video stream, a navigation menu etc) to a user. The control device 30 is configured to receive a selection of a navigation mode for the control device 30, and to generate and display contextual information in relation to the content displayed on the display device 80 in response to a receipt of the selection of the navigation mode. Thus, the contextual information generated and displayed by the control device 30 depends on the selection of navigation mode for the control device 30.
In an advantageous embodiment, the control device 30 is adapted to receive the selection of the navigation mode upon a change of orientation of the control device 30. This embodiment of the control device 30 is advantageous in that it enables a user of the control device 30 to easily or quickly change the contextual information generated and displayed by the control device 30 by simply changing the orientation of the control device 30.
In a particularly advantageous embodiment, the control device 30 is additionally configured to communicate with the display device 80 to control the display device 80 in different modes of operation based on the orientation of the control device 30. This particularly advantageous embodiment has an additional advantage that it enables a user of the control device 30 to easily or quickly alternate between different ways of controlling the display device 80 by simply changing the orientation of the control device 30.
FIG. 1A is a block diagram of the physical components of an embodiment of the control device 30 in data communication with a display device 80. In this embodiment, the display device 80 is an IFE touchscreen display and the control device 30 is a handset controller for controlling the IFE display. However, it is envisaged that the display device 80 may not be an IFE display and that the control device 30 may not be a handset controller for controlling an IFE display. In particular, it is envisaged that the display device 80 need not be a touchscreen display.
The control device 30 comprises an orientation detection mechanism 50, a processor 60 and a display 90.
The orientation detection mechanism 50 is adapted to detect a change of orientation of the control device 30. In this embodiment, the orientation detection mechanism 50 is a gyroscope. However, it is envisaged that the orientation detection mechanism 50 may not be a gyroscope. For example, the orientation mechanism 50 may alternatively be an accelerometer in an alternative embodiment. Also, it is envisaged that there may be two or more separate mechanisms in the orientation detection mechanism 50. For example, the orientation mechanism 50 may include an accelerometer in addition to a gyroscope in an alternative embodiment.
The processor 60 is configured to generate contextual information in relation to the content displayed on the IFE display 80. The processor 60 generates the contextual information automatically in response to detection by the orientation detection mechanism 50 that there is a change of orientation of the control device 30. Examples of contextual information that may be generated by the processor 60 include: a simplified or modified version of the content displayed by the IFE display 80 (such as a version including only text and not the images of the content, a version comprising only a portion of the content, or a scaled down version of the content), a navigation menu comprising a number of shortcuts or links for enabling a user to control the IFE display 80 to change the content displayed on the IFE display 80 etc. A more detailed description of an example of the contextual information generated by the processor 60 is provided below.
The display 90 of the control device 30 is adapted to display the contextual information generated by the processor 60. The control device 30 is configured to display the contextual information generated by the processor 60 on the display 90 automatically after the contextual information is generated by the processor 60.
In this embodiment, the display 90 is a touchscreen display adapted to receive a touch input (for example, when a user performs on the display 90 a swiping or paging action, a tracking or dragging action, a single tap action, a double tap action, a press and hold action etc). New Contextual information may be generated by the processor 60 and displayed by the touchscreen display 90 in response to either a change of orientation detected by the gyroscope 50 or a touch input on the display 90 from a user. For example, the IFE display 80 may change the content displayed by the IFE display 80 from one of a series of inter-related content (such a photograph or picture of an album) to a subsequent one of the series of inter-related content when a user performs a swiping or paging action on the touchscreen display 90. Also, contextual information displayed on the touchscreen display 90 may be modified while a user is touching the touchscreen display 90. For example, the touchscreen display 90 may highlight a portion of the content displayed by the IFE display 80 corresponding to a portion displayed by the touchscreen display 90 depending on the spatial position of the finger on the touchscreen display 90, or when a user performs a tracking or dragging action on the touchscreen display 90 to the portion displayed by the touchscreen display 90.
The control device 30 also includes a communication interface 20. The communication interface 30 enables the control device 30 to communicate with the IFE display 80 to control or cause the IFE display 80 to change the content displayed by the IFE display 80. The control device 30 automatically communicates with the IFE display 80 via the communication interface 20 to control or cause the IFE display 80 to change the content displayed by the IFE display 80 in response to the touchscreen display 90 receiving a touch input.
The communication from the control device 30 to the IFE display 80 depends on the contextual information displayed on the touchscreen display 90. Thus, the operation of the contact device 30 is different depending on the orientation of the control device 30. In this embodiment, the control device 30 is operable in a “Quick” mode where the touchscreen display 90 displays a navigation menu comprising a plurality of links, and a “Sequential” mode where the touchscreen display 90 displays either a simplified, modified or scaled down version of the content displayed on the IFE display 80. Depending on implementation, the control device 30 may default to either the “Quick” mode or the “Sequential” mode when in use. A more detailed description of the two modes is described below.
It will be appreciated that the control device 30 is configured to operate in real-time such that the changes to the contextual information on the touchscreen 90 of the control device 30 is substantially synchronized with the changes to the content on the IFE display 80.
It is envisaged that the control device 30 may additionally be configured to communicate with the IFE display 80 to control or cause the IFE display 80 to change the content displayed by the IFE display 80 in response to a detection of a change of orientation of the control device 30 by the gyroscope 50 even if no touch input is received. For example, changing the orientation of the control device 30 may automatically result in a display of a navigation menu on the IFE display 80.
Also, it is envisaged that the control device 30 may include additional components. For example, the control device 30 may include additional input mechanisms such as a gamepad.
FIG. 1B is a functional block diagram of the processor 60 of the control device of FIG. 1A.
Persons skilled in the art will appreciate that the processor 60 may be implemented in different ways. In this embodiment, the processor 60 is a processing unit implementing a number of software modules based on program code and data stored in a memory 66 of the processor 60. However, persons skilled in the art will appreciate that one or more of the modules may alternatively be implemented by a dedicated programmable logic controller (PLC). Also, persons skilled in the art will appreciate that the modules may be distributed between the control device 30 and the IFE system.
The modules implemented by the processor 60 include a communication interface controller 63, a gyroscope controller 63, a touchscreen controller 68, and a contextual information generator 69.
The communication interface controller 63 is configured to receive data (such as data with respect to the content displayed by the IFE system 80 etc) from the IFE device 80, and to transmit data (such as commands to control the IFE device 80 etc) to the IFE device 80.
The gyroscope controller 63 is configured to receive a detection of a change of orientation of the control device 30 by the gyroscope 50.
The contextual information generator 69 is configured to generate contextual information based on a detection of a change of orientation of the control device 30 by the gyroscope 50 or a receipt of a touch input by the control device 30. In this respect, it will be appreciated that the contextual information may be generated in different ways depending on the type of contextual information to be generated. For example, the contextual information may be generated based on data received by the control device 30 from the IFE display 80. Alternatively, the contextual information may be generated simply by retrieving data stored in the memory 66.
The touchscreen controller 68 is configured to control the touchscreen display 90 to display or modify the contextual information generated by the contextual information generator 69, and to receive touch inputs from the touchscreen display 90.
FIG. 2 is a flowchart of an embodiment of the method of the present invention. At step 110, the control device 30 receives from the IFE display 80 via the communication interface 20 content data with respect to content displayed on the IFE display 80. At step 120, the gyroscope 50 of the control device 30 detects a change of orientation of the control device 30. At step 130, the processor 60 of the control device 30 generates contextual information based on the detected change of orientation and the content data received via the communication interface 20 from the IFE display 80. At step 150, the touchscreen 90 of the control device 30 displays the contextual information generated by the processor 60. At step 160, the control device 30 receives a touch input from a user via the touchscreen 90. At step 180, the control device 30 communicates data with the IFE display 80 to transmit data with respect to the touch input. At step 190, the IFE display 80 displays new content based on the communication from the control device 30 at step 180.
FIG. 3A is a block diagram of the physical components of an alternative embodiment of the control device 300. Like the embodiment of FIGS. 1A and 1B, the control device 300 is also a handset controller for controlling an IFE display 380 for displaying content to a user.
The handset controller 300 comprises a processor 360 and a display 390 in the form of a touchscreen display. The touchscreen display 390 is adapted to receive a touch input for selecting a navigation mode for the handset controller 300. In this embodiment, the touch input corresponds to a swiping or dragging action on or close to a perimeter of the touchscreen display 390 of the handset controller 300 by the user. However, persons skilled in the art will appreciate that the touch input may be on a portion of the touchscreen display 390 that is not on or close to the perimeter of the touchscreen display 390, or may be a touch action that is different to a swiping or dragging action (such as a tapping action). Also, it is envisaged that an alternative embodiment of the handset controller 300 may comprise a gyroscope (like the one described with respect to the embodiment of FIGS. 1A and 1B), and may be additionally configured to receive a selection of a navigation mode for the handset controller 300 via a change of orientation of the handset controller 300.
The processor 360 is configured to receive a selection of the navigation mode upon the touchscreen display 390 receiving the touch input for selecting the navigation mode for the handset controller 300. The processor 360 is also configured to generate contextual information in relation to the content displayed on the IFE display 380 in response to receipt of the selection of the navigation mode, and to display the generated contextual information on the touchscreen display 390 of the handset controller 300.
The handset controller 300 also includes a communication interface 320 to enable the handset controller 300 to communicate with the IFE display 380 to control or cause the IFE display 380 to change the content displayed by the IFE display 380. The handset controller 300 automatically communicates with the IFE display 380 via the communication interface 320 to control or cause the IFE display 380 to change the content displayed by the IFE display 380 in response to the touchscreen display 390 receiving a touch input.
FIG. 3B is functional block diagram of the processor 360 of the handset controller 300 of FIG. 3A.
The processor 360 is configured to implement a number of modules based on program code and data stored in a memory 366 of the processor 360. The modules include a navigation mode receiver 362, a touchscreen controller 368, a contextual information generator 369 and a communication interface controller 363.
The navigation mode receiver 362 is configured to receive a selection of the navigation mode for the handset controller 300 upon the touchscreen display 390 of the handset controller 300 receiving a swiping or dragging action on or close to a perimeter of the touchscreen display 390 of the handset controller 300.
The contextual information generator 369 is configured to generate contextual information based on the selected navigation mode in response to a receipt of the selection of the navigation mode by the navigation mode receiver 362.
The touchscreen controller 368 is configured to control the touchscreen display 390 of the handset controller 300 to display the contextual information generated by the contextual information generator 369.
The communication interface controller 363 is configured to receive data (such as content data) from the IFE device 380 via the communication interface 320 of the handset controller 300, and to transmit data (such as request data for requesting content data, and command data to change the content displayed by the IFE display 380) via the communication interface 320 to the IFE device 380.
In this embodiment, the handset controller 300 is operable in two navigation modes: the quick navigation mode and the sequential navigation mode. However, it is envisaged that the handset controller 300 may be operable in more than two navigation modes and that the processor 360 of the handset controller 300 may be configured to switch between the various modes depending on the touch input for selecting the navigation mode from the user. For example, while the handset controller 300 is operating in a first navigation mode, a touch input on a first perimeter of the touchscreen display 390 may cause the handset controller 300 to switch to a second navigation mode, but a touch input on a second perimeter of the touchscreen display 390 that is not the same as the first perimeter may cause the handset controller 30 to switch to a third navigation mode.
FIG. 4 a flowchart of an embodiment of the method of the present invention. At step 220, the touchscreen display 390 of the handset controller 300 receives a touch input corresponding to a swiping or dragging action on or close to a perimeter of the touchscreen display 390. Upon the touchscreen display 390 receiving the touch input, the navigation mode receiver 362 implemented by the processor 300 of the handset controller 300 receives a selection of a navigation mode for the handset controller 300. At step 240, the communication interface controller 363 implemented by the processor 360 of the handset controller 300 receives content data from the IFE display 380 via the communications interface 320 of the handset controller 300 after the communication interface controller 363 transmits a request for the content data to the IFE display 380 via the communications interface 320. At step 260, the contextual information generator 369 implemented by the processor 360 of the handset controller 300 generates contextual information based on the content data received from the IFE display 380 and the selected navigation mode.

FIG. 9A is a block diagram of the physical components of yet another alternative embodiment of the control device 600. Like the embodiment of FIGS. 1A, 1B, 3A and 3B, the control device 600 is also a handset controller for controlling an IFE display 680 for displaying content to a user. The handset controller 600 is in data communication with a motion detector 630. However, it is envisaged that an alternative embodiment of the handset controller 600 may not be in data communication with a motion detector. The motion detector 630 is an infrared sensor. However, persons skilled in the art will appreciate that the motion detector 630 may not be an infrared sensor. For example, the motion detector 630 may alternatively be a microwave sensor or an ultrasonic detector.
The handset controller 600 comprises a communication interface 620 for communicating with the IFE display 680 and the infrared sensor 630, for example, to output data to the IFE display 680 to change the content displayed on the IFE display 680, and to receive from the infrared sensor 630 data indicating a motion detected by the infrared sensor 630.
The handset controller 600 also comprises a touchscreen display 690 and a processor 660 for controlling the touchscreen display 690 and the communication interface 620. The touchscreen display 690 is responsive to a touch input for controlling the IFE display 680 and/or the handset controller 600. For example, a user of the handset controller 600 can change content displayed on the IFE display 680 and/or content displayed on the touchscreen display 690 by touching or contacting the touchscreen display 690. As indicated above with respect to the embodiments of FIGS. 1A, 1B, 3A and 3B, the touch input may be a swiping, tapping or dragging action.
The handset controller 600 is operable in at least two navigation modes: a touchpad mode and a trackpad mode. In the touchpad mode, the touchscreen display 690 of the handset controller 600 is responsive to touch inputs and displays information to facilitate controlling the IFE display 680. In the trackpad mode, the touchscreen display 690 of the handset controller 600 is responsive to touch inputs, but is disabled from displaying information to facilitate controlling the IFE display 680. Depending on the implementation, the touchscreen display 690 may be disabled by disabling the touchscreen display 690 from displaying just information that facilitates controlling of the IFE display 680 or any information. Persons skilled in the art would appreciate that disabling the touchscreen display 690 from displaying information may in effect be the same as controlling the touchscreen display 690 to display a blank image, or simply not updating the display on the touchscreen 690.
In this embodiment, when the handset controller 600 is operating in the touchpad mode, a scaled down version of the content displayed on the IFE display 680 is shown on touchscreen display 690. An action on the touchscreen display 690 would be mirrored on the IFE display 680. For example, a left swipe action on the touchscreen display 690 would change the content on both the touchscreen display 690 and the IFE display 680. In an alternative embodiment, contextual information corresponding to the content displayed on the IFE display 680 may be shown on the touchscreen display 690 in addition to the scaled down version of the content displayed on the IFE display 680.
It is envisaged that an alternative embodiment of the handset controller 600 may be operable in more than two navigation modes. For example, an alternative embodiment of the handset controller 600 may additionally be operable in a display mode where the touchscreen display 690 displays information to facilitate controlling the IFE display 680, but is disabled from receiving any touch inputs (in effect ignoring any touch inputs provided to the touchscreen display 690). In another example, an alternative embodiment of the handset controller 600 may additionally operate in the quick navigation mode or the sequential navigation mode indicated in relation to the embodiment of FIGS. 3A and 3B.
Also, it is envisaged that an alternative embodiment of the handset controller 600 may change the manner in which the handset controller 600 must be used when the handset controller 600 changes from the touchpad mode to the trackpad mode. For example, in an alternative embodiment, when the handset controller 600 changes from the touchpad mode to the trackpad mode, an indicator (like a mouse pointer) may be displayed on the IFE display 680. In such an alternative embodiment, a dragging action on the touchscreen 690 of the handset controller 600 may just move the indicator like a traditional trackpad.
FIG. 9B is functional block diagram of the processor 660 of the handset controller 600 of FIG. 9A. The processor 660 is configured to implement a number of modules based on program code and data stored in a memory 366 of the processor 360. The modules include a navigation mode receiver 662, a touchscreen controller 668, a contextual information generator 669 and a communication interface controller 663.
The navigation mode receiver 662 is configured to receive a selection of the navigation mode for the handset controller 600 upon a touch input for selecting a navigation mode provided on the touchscreen display 690 of the handset controller 600. The touch input for selecting the navigation mode is a tapping action on a portion of a navigation menu displayed on the touchscreen display 690. However, it is envisaged that the touch input may not be a tapping action on a portion of a navigation menu displayed on the touchscreen display 690. For example, the touch input for selecting the navigation mode may alternatively be a swiping or dragging action on a designated portion of the touchscreen display 690 of the handset controller 600 in an alternative embodiment. It is also envisaged that in an alternative embodiment, a selection of the navigation mode may not be received by the touchscreen display 690. For example, a selection may be received by an alternative embodiment of the handset controller 600 upon a detection of a hand motion by the infrared sensor 630, or in an embodiment where the IFE display is a touchscreen display, upon a touch input provided to the IFE display.
The contextual information generator 669 is configured to generate contextual information when the handset controller 600 operating in the touchpad mode. Like the embodiments of FIGS. 1A, 1B, 3A and 3B, the contextual information may be generated based on content data with respect content display on the IFE display 680. In an embodiment where the handset controller 600 is adapted to operate in different touchpad modes (for example, the quick navigation mode and the sequential navigation mode mentioned above), the contextual information may be generated depending on which navigation mode the handset controller 600 is operating in.
The touchscreen controller 668 is configured to control the touchscreen display 690 of the handset controller 300 to display the contextual information generated by the contextual information generator 669 when the handset controller 600 operating in the touchpad mode, and to control the touchscreen display 690 to disable the touchscreen display 690 from displaying information when the handset controller 600 operating in the trackpad mode.
The communication interface controller 663 is configured to receive data from the IFE display 680 via the communication interface 620, and to transmit data via the communication interface 620 to the IFE display 680. In particular, the communication interface controller 663 is configured to receive data (such as data with respect to the content displayed by the IFE display 680) from the IFE display 680, and to transmit data (such as commands to control the IFE display 680) to the IFE display 680.
FIG. 10 a flowchart of an embodiment of the method of the present invention. At step 500, while operating in the touchpad mode, the handset 600 receives from the IFE display 680 content data with respect to content displayed on the IFE display 680 via the communication interface 620 of the handset 600. At step 510, the contextual information generator 669 implemented by the processor 660 generates contextual information based on the content data received from the IFE display 680. At step 520, the touchscreen controller 668 implemented by the processor 660 controls the touchscreen 690 of the handset 600 to display the contextual information generated by the contextual information generator 669.
At step 530, the handset 600 receives a user input in the form of a touch input provided by a user of the handset 600 on the touchscreen 690. As indicated above, the user input may alternatively be received upon a detection of a motion by the infrared sensor 630. At step 540, the communication interface controller 663 implemented by the processor 660 controls the communication interface 620 to transmit to the IFE display 680 data with respect to the touch input, and the contextual information generator 669 generates new contextual information based on the touch input. At step 550, the IFE display 680 displays new content based on the data transmitted from the handset 600, and the touchscreen 690 displays the new contextual information generated by the contextual information generator 669.
At step 560, the handset 600 receives another touch input corresponding to a selection of the trackpad mode for the handset 600. At step 570, the navigation mode controller 662 controls the touchscreen 690 to disable the touchscreen from displaying any contextual information.
At step 580, the handset 600 receives yet another touch input provided by a user of the handset 600 on the touchscreen 690. At step 540, the communication interface controller 663 implemented by the processor 660 controls the communication interface 620 to transmit to the IFE display 680 data with respect to the touch input, and the IFE display 680 displays new content based on the data transmitted from the handset 600.
