Abstract
A method and apparatus that resolve near touch ambiguities in a touch screen includes detecting a touch screen touch event and detecting a vibro-acoustic event. These events generate signals received respectively by two different sensors and/or processes. When the two events occur within a pre-defined window of time, they may be considered to be part of the same touch event and may signify a true touch.
Claims20
A method for reducing unintentional activation of a touch-sensitive display, the method comprising:
- providing a first sensor for detecting a first event indicating an apparent activation of said touch-sensitive display;
- providing a second sensor for detecting a second event indicating an apparent activation of said touch-sensitive display, wherein said first and second events being distinctly different physical phenomena, wherein the second sensor is a vibro-acoustic event sensor;
- and
- activating said touch-sensitive display only when both said first and second sensors detect respective first and second events within a selected time window.
(canceled)
An apparatus for use in conjunction with a touch-sensitive display for reducing unintentional activation of the display, the apparatus comprising:
- a first sensor for detecting a first event indicating an apparent activation of said touch-sensitive display;
- a second sensor for detecting a second event indicating an apparent activation of said touch-sensitive display, wherein said first and second events being distinctly different physical phenomena, wherein the second sensor is a vibro-acoustic event sensor;
- and
- at least one logic device responsive to said first and second sensors for activating said touch-sensitive display only when both said first and second sensors detect respective first and second events within a selected time window.
(canceled)
A computer readable medium containing instructions for reducing inadvertent activation of a touch-sensitive display, wherein execution of the program instructions by a processor causes the processor to carry out the steps of:
- providing a first sensor for detecting a first event indicating an apparent activation of said touch-sensitive display;
- providing a second sensor for detecting a second event indicating an apparent activation of said touch-sensitive display, wherein said first and second events being distinctly different physical phenomena, wherein the second sensor is a vibro-acoustic event sensor;
- and
- activating said touch-sensitive display only when both said first and second sensors detect respective first and second events within a selected time window.
