Method and apparatus for improving power consumption on a touch device

摘要

Lower report rates are desirable in touch devices to minimize power consumption. However, lower report rates lead to inaccurate and untimely depiction of a user's touch inputs on a touch display device. Disclosed are methods and apparatus for using a lower report rate; while maintaining substantially the same or better user experience achieved by using a higher report rate.

主权项

1. An apparatus for generating touch inputs, comprising:
a touch device; and a processor configured to:
receive, from the touch device, data representing a sensed time and sensed location on the touch device of each of a plurality of sensed touch inputs;generate a model of the sensed touch inputs by calculating a best fit for parameters of an upsampling function based on the sensed location and sensed time of at least some of the plurality of the sensed touch inputs;upsample the sensed touch inputs using the model to generate at least one additional touch input at a point of the upsampling function corresponding to a time at which there is no sensed touch input and which is after a sensed time of a most recent sensed touch input of the plurality of sensed touch inputs, the point corresponding to an additional location on the touch device; anddisplay a visual representation of
the sensed touch inputs at the sensed locations on the touch device, andthe at least one additional touch input at the additional location on the touch device.
