GLOVE TOUCH DETECTION

摘要

The dynamic adjusting of the conditions for identifying inputs as touching a touch-sensitive device is discloses. In some examples, in addition to using a signal density make threshold to identify an input patch as touching the surface, a signal density stability threshold can be used to identify the input patch as touching the surface. In some examples, a weighted average of peak signal density contributions from recent identified touches can be computed to dynamically adjust the make threshold for new input patches. In other examples, a new input patch identified as associated with the same path as an earlier touch can have its “make” threshold dynamically adjusted based on the earlier touch without computing a weighted average.

1. A touch detection method comprising:
identifying at least one patch from a touch image of one or more objects proximate to a touch sensitive surface; determining a signal density of the at least one patch; determining whether the signal density of the at least one patch reaches or exceeds a first threshold, the first threshold dynamically adjusted based on one or more recent contacts; and in response to determining that the signal density of the at least one patch reaches or exceeds the first threshold, determining that the object is contacting the touch sensitive surface.
