Disambiguating Touch-Input Based on Variation in Pressure Along A Touch-Trail

摘要

Disclosed is a method and corresponding apparatus or system for disambiguating touch-input based on variation in a characteristic such as speed or pressure along a touch-trail (20, 26). A computing system may detect a variation in a characteristic of a touch-trail, such as variation in speed of movement of touch along the touch-trail and/or a variation in pressure of touch along the touch-trail (step 52). Based on the detected variation, the computing system may determine an intended touch position represented by the trail, such as a landing position or lifting position for instance (step 54). And the computing system may take action based at least in part on that determined touch position (step 56).

主权项

1. A method comprising:
detecting, by a computing system, a trail of touch input at a touch-sensitive input surface, the trail being defined by movement of the touch input from a landing position to a lifting position; detecting, by the computing system, a variation in pressure of the touch input along the detected trail; determining, by the computing system, an input-position represented by the detected trail, wherein the determining is based at least in part on the detected variation; and generating, by the computing system, an output signal based at least in part on the determined input-position of the detected trail.
