Patent ID: 8904313

Claim:
A computer program product, comprising: a non-transitory computer readable storage medium to store a computer readable program, wherein the computer readable program, when executed by a processor within a computer, causes the computer to perform operations for gesture control of a quantitative input, the operations comprising: detecting a numerical value displayed as text in an application; entering an edit mode in response to detecting a touch gesture input on the numerical value on a touch display device; displaying an interface control in a user interface on the touch display device for the numerical value in response to entering the edit mode, wherein the interface control is an interactive interface element configured to set an interface value for the numerical value, the interface value selected from an ordered continuum of values; changing the interface value for the numerical value in response to detecting a change in the shape of the gesture input while in the edit mode, wherein the shape varies throughout a range of lateral and anterior shapes of a fingertip of a user as the fingertip is rolled; detecting a change in a position of the gesture input for the interface control on the touch display device while in the edit mode; and while in the edit mode modifying a gain for changing the interface value based on the change in the position of the gesture input relative to a position of the interface control, wherein the gain is a rate at which the interface value changes in larger or smaller step size increments based on the position of the gesture input relative to the position of the interface control.
