Patent ID: 8810509

Claim:
A method performed by a computing device comprising a display and an input device, the method comprising: monitoring discrete unbroken strokes inputted by a user of the computing device to detect, among the strokes, first unbroken strokes and second unbroken strokes, each discrete unbroken stroke comprising an uninterrupted input inputted by the user providing input from only a single finger; the monitoring detecting the first strokes by analyzing features of the strokes to determine that the first strokes have features that correspond to the first strokes: (i) having been inputted by only a single finger, and (ii) having ended with the single finger having moved substantially in only two predefined directions, and (iii) having never been accompanied by input from any other fingers, the two predefined directions comprising a first direction and then a second direction, the first direction different than the second direction; each time a first stroke is detected, responding by automatically activating a first function on the computing device; the monitoring detecting the second strokes by analyzing features of the strokes to determine that the second strokes have features that correspond to (i) having been inputted by only a single finger, and (ii) having ended with the single finger having moved substantially in only the two directions, and (iii) having been accompanied by input from only one other finger that moved substantially in only the second direction; and each time a second stroke is detected, responding by automatically activating a second function on the computing device.
