Abstract
A method of filtering a touch screen input is disclosed that includes the steps of detecting a position of a first touch on a touch screen, determining a validation area that includes the position of the first touch, detecting a position for each of one or more second touches on the touch screen, and providing a touch event signal if the positions of all of the second touches are within the validation area.
Claims37
A method of filtering a touch screen input, the method comprising the steps of:
- detecting a position of a first touch on a touch screen from a finger impression;
- determining a validation area that includes the position of the first touch;
- detecting a position for each of one or more second touches on the touch screen, the first touch and the second touches located within a fingerprint area of the finger impression;
- and
- providing a touch event signal if the positions of all of the second touches are within the validation area.
A non-transitory computer-readable medium having computer-executable instructions stored thereon for execution by a processor to perform a method of filtering touch screen inputs, the method comprising the steps of:
- detecting a position of a first touch on a touch screen;
- determining a validation area that includes the position of the first touch;
- detecting a position for each of one or more second touches on the touch screen, the first touch and the second touches located within a fingerprint area of the finger impression;
- and
- providing a touch event signal if the positions of all of the second touches are within the validation area.
A method of filtering touch screen inputs, the method comprising the steps of:
- detecting a position for each of a plurality of touches on a touch screen, the plurality of touches located within a fingerprint area of a finger impression;
- and
- providing a touch event signal if the positions of all of a determined number of most recent touches are within a trigger area associated with the fingerprint area.
A non-transitory computer-readable medium having computer-executable instructions stored thereon for execution by a processor to perform a method of filtering touch screen inputs, the method comprising the steps of:
- detecting a position for each of a plurality of touches on a touch screen, the plurality of touches located within a fingerprint area of a finger impression;
- and
- providing a touch event signal if the positions of all of a determined number of most recent touches are within a trigger area associated with the fingerprint area.
A method of filtering touch screen inputs, the method comprising the steps of:
- starting a count-down timer with a determined period of count-down time and setting a counter to 1 and determining a validation area upon detection of a first touch;
- incrementing the counter upon determining that a position of another touch detected before the timer times out is within the validation area;
- and
- providing a touch-down event signal if the counter is greater than or equal to a determined number.
A non-transitory computer-readable medium having computer-executable instructions stored thereon for execution by a processor to filter touch screen inputs, the filtering comprising the steps of:
- starting a count-down timer at a determined period of count-down time and setting a counter to 1 and determining a validation area upon detection of a first touch;
- incrementing the counter upon determining that a position of another touch detected before the timer times out is within the validation area;
- and
- providing a touch-down event signal if the counter is greater than or equal to a determined number.
A medical device comprising:
- a touch screen configured to sense a touch;
- a processor configured to accept a touch event signal;
- and
- a touch screen controller coupled to the touch screen and the processor, the controller configured to:
- detect a position of a first touch on the touch screen from a finger impression;
- determine a validation area that includes the position of the first touch;
- detect a position for each of one or more second touches on the touch screen, the first touch and the second touches located within a fingerprint area of the finger impression;
- and
- provide a touch event signal to the processor if the positions of all of the second touches are within the validation area.
