Abstract
A method comprises receiving a gesture as an input to a display screen; detecting the gesture via a controller; determining whether the gesture was received on a target touch interface or in a defined area adjacent to the target touch interface; determining whether the gesture was intended to be received on the target touch interface; and providing an output based on the determination of whether the gesture was intended to be received on the target touch interface. Determining whether the gesture was intended to be received on the target touch interface comprises measuring a length of time of contact of the gesture with the display screen and measuring a proximity of a point of contact of the gesture from the touch interface.
Claims20
An apparatus, comprising:
- a display screen, comprising:
- at least one touch interface on the display screen, the at least one touch interface comprising a first plurality of touch-sensing pixels, and
- a gravity field of control adjacent to at least one of the at least one touch interfaces, the gravity field of control comprising a second plurality of touch-sensing pixels;
- and
- a controller configured to receive an input from one of the first plurality of touch-sensing pixels and the second plurality of touch-sensing pixels, the controller being further configured to process the received input by measuring a length of time of contact of the input on the first plurality of touch-sensing pixels or the second plurality of touch-sensing pixels and measuring a proximity of a point of contact of the input from the at least one touch interface to determine whether the input is intended for the at least one touch interface, and the controller being further configured to provide an output based on the processed input.
A method, comprising:
- receiving a gesture as an input to a display screen;
- detecting the gesture via a controller;
- determining whether the gesture was received on a target touch interface or in a defined area adjacent to the target touch interface;
- determining whether the gesture was intended to be received on the target touch interface;
- and
- providing an output based on the determination of whether the gesture was intended to be received on the target touch interface;
- wherein determining whether the gesture was intended to be received on the target touch interface comprises measuring a length of time of contact of the gesture with the display screen and measuring a proximity of a point of contact of the gesture from the touch interface.
A computer program product for applying assistive touch detection in an electronic device, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a computer to cause the device to perform a method comprising:
- receiving a gesture as an input to a display screen;
- detecting the gesture via a controller;
- determining whether the gesture was received on a target touch interface or in a defined area adjacent to the target touch interface;
- determining whether the gesture was intended to be received on the target touch interface;
- and
- providing an output based on the determination of whether the gesture was intended to be received on the target touch interface;
- wherein determining whether the gesture was intended to be received on the target touch interface comprises measuring a length of time of contact of the gesture with the display screen and measuring a proximity of a point of contact of the gesture from the touch interface.
