1. A method comprising:
- by a computing device, determining a touch gesture on a touch screen of the computing device, the touch gesture comprising two or more data points that each correspond to a particular location on the touch screen and a particular point in time, wherein the data points correspond to different respective points in time;
by the computing device, for each of one or more of the data points, adjusting a time value representing its particular point in time with respect to time values for respective other ones of the data points;
by the computing device, for each of one or more of the data points, adjusting a position value representing its particular location on the touch screen with respect to position values representing particular locations for the respective other ones of the data points; and
by the computing device, fitting a curve to the two or more data points to determine a user intent associated with the touch gesture.

Abstract
In one embodiment, a computing device determines a touch gesture on a touch screen of the computing device. The touch gesture includes two or more data points that each correspond to a particular location on the touch screen and a particular point in time. For each of one or more of the data points, the computing device adjusts a time value representing its particular point in time. For each of one or more of the data points, the computing device adjusts a position value representing its particular location on the touch screen. The computing device fits a curve to the two or more data points to determine a user intent associated with the touch gesture.

16. A first computing system comprising:
-
a memory comprising instructions executable by one or more processors; and the one or more processors coupled to the memory and operable to execute the instructions, the one or more processors being operable when executing the instructions to; determine a touch gesture on a touch screen of the computing device, the touch gesture comprising two or more data points that each correspond to a particular location on the touch screen and a particular point in time, wherein the data points correspond to different respective points in time; for each of one or more of the data points, adjust a time value representing its particular point in time with respect to time values for respective other ones of the data points; for each of one or more of the data points, adjust a position value representing its particular location on the touch screen with respect to position values representing particular locations for the respective other ones of the data points; and fit a curve to the two or more data points to determine a user intent associated with the touch gesture. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. One or more computer-readable non-transitory storage media in one or more computing systems, the media embodying logic that is operable when executed to:
-
determine a touch gesture on a touch screen of one of the computing systems, the touch gesture comprising two or more data points that each correspond to a particular location on the touch screen and a particular point in time, wherein the data points correspond to different respective points in time; for each of one or more of the data points, adjust a time value representing its particular point in time with respect to time values for respective other ones of the data points; for each of one or more of the data points, adjust a position value representing its particular location on the touch screen with respect to position values representing particular locations for the respective other ones of the data points; and fit a curve to the two or more data points to determine a user intent associated with the touch gesture. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
