Abstract:
1. A computer-implemented process comprising: receiving into memory information describing contact points on a touch device into memory; receiving into memory z-direction information from the touch device; generating in memory state information related to the contact points according to the z-direction information, by applying a plurality of thresholds to the z-direction information, the plurality of thresholds defining a plurality of states, the plurality of states including at least an idle state, an engage state associated with a first threshold for entry to the engage state, and an engage locked state associated with a second threshold for entry to the engage locked state, the second threshold exceeding the first threshold; wherein the engage locked state is entered by a transition from any other state when the z-direction information exceeds the second threshold; and wherein after entry into the engage locked state, the engage locked state is exited by a change in the z-direction information to below the second threshold and then over the second threshold.
