International ClassH01C 010/12AbstractA method of using an analog sensor variably depressed by only a single human finger to variably control an electronic game, the method including the steps: a) depressing, with the human finger, the analog sensor with varying pressure for variably controlling the electronic game; and b) receiving, through the finger, a user discernible snap-through tactile feedback. Additionally, a second depressing may be applied substantially because of the receiving of the feedback.Other References
