Abstract
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.
