TOUCH SCREEN DEVICE, METHOD, AND GRAPHIC USER INTERFACE FOR DETERMINING COMMAND BY APPLYING HEURISTIC

摘要

PROBLEM TO BE SOLVED: To provide an electronic device which determines a command by applying heuristics to a user gesture detected on a touch screen display.

SOLUTION: A computing method using the touch screen display includes: a step of determining the command for the device by applying one or more heuristics to one or more finger touches on the touch screen display; and a step of processing the command. The one or more heuristics include a heuristic method for determining that the one or more finger touches correspond to a linear vertical screen scrolling command, a heuristic method for determining that the one or more finger touches correspond to a two-dimensional screen translational movement command, and a heuristic method for determining a command for transition to displaying of respective items in an item set by the one or more finger touches and further displaying of a next item in the item set.
