Abstract:
A peripheral electronic device is described which is configured to communicate with a computing device comprising a display having a screen configured to display a virtual gaze cursor; wherein the peripheral electronic device comprises at least one user interface configured to trigger at least one operational command in response to interaction with a user, wherein the at least one operational command is associated with a current location of the virtual gaze cursor at the screen, and wherein a change at the current location of the virtual gaze cursor being displayed, is determined based on a shift of a user's gaze from a first location at said screen to a different location thereat, or based on a tilt of the user's head, or based on any combination thereof.
Abstract:
The present invention relates to an image display device and a method for operating same. According to an embodiment of the present invention, a method for operating an image display device uses a remote controller, and comprises the steps of: displaying a pointer in a first area of a display; receiving movement coordinate information of the pointer from the remote controller; restoring the first area using a prestored image when the first area does not overlap a second area where a pointer is displayed, based on the movement coordinate information; storing an image of the second area; and displaying a pointer in the second area. This enables the pointer of the remote controller to be easily displayed.
Abstract:
A control device (1 18) includes a position sensing component (202) that senses a position of the control device relative to a free space coordinate system and generates a signal indicative thereof, and a transmitter (210) that transmits the signal to an imaging system that employs the signal to position a graphical cursor on a display of the imaging system in coordination with the position of the sensing component in free space. An imaging apparatus (100) includes a scanner (102), including an interface (108) configured to connect with a complementary interface of an imaging transducer probe. A display (1 16) presents information indicative of a signal sensed by the imaging transducer probe. A processor (224) generates and positions a graphical cursor of a display region of the display based on a position of a control device, which is registered to operate the scanner, in free space.
Abstract:
Rolling gestures on a touch sensitive surface of a device can be used to control the device or to remotely control another device. The device detects a roll, determines a parameter of the roll and performs an operation relating to the device or the other device based on the determined parameter. The touch sensitive surface of the device can be positioned on the device to enable a set of gestures for configuring the operation of the device, for operating the device and for enabling additional gestures for operating the device.
Abstract:
It is known to display a cursor field of variable magnitude notably for accentuating text segments on a display screen. No separate symbol is reproduced in this cursor field. On the other hand, it is also known to display a cursor symbol in a cursor field, where the areas of the cursor field outside the symbol are generally suppressed. The position of this field can be controlled, but the magnitude is always fixed. The shape of the cursor symbol is often stored in a random access memory so that it can be readily modified. For the display of also a cursor symbol of variable magnitude, the invention proposes to address the cursor memory by means of a separate addressing device which operates only during display of the cursor field. The organization of the memory for the cursor symbol, customarily constructed as a matrix memory, then becomes fully independent of the rows and columns of the cursor field, i.e. to the cursor symbol the memory appears as a pure linear memory. As a result, this memory can be utilized in a substantially improved manner and the display of even large cursor symbols requires only a limited storage capacity.
