Abstract:
1. A method comprising: at a computing device with a multipoint sensing touch screen display, a processor, and a memory: detecting a touch by a user on the multipoint sensing touch screen display; determining a behavior of the user's touch by processing signals created by the multipoint sensing touch screen display in response to the user's touch, wherein the behavior includes spatial domain behavior and time domain behavior; accessing a data structure in the memory, the data structure comprising data representing: matching the determined behavior of the user's touch to a predetermined behavioral characteristic for a virtual key; determining a reaction for the virtual key in the data structure that corresponds to the matched predetermined behavioral characteristic for the virtual key; and performing an action that corresponds to the determined reaction, wherein a first virtual key in the plurality of virtual keys requires a first pressure to be activated, a second virtual key in the plurality of virtual keys requires a second pressure to be activated, and the first pressure is less than the second pressure, and wherein the first virtual key is adjacent to the second virtual key.
