Remote multi-touch

摘要

A remote multi-touch system includes a pressure-sensitive, multi-touch device, a display separate from the pressure-sensitive, multi-touch device, and a controller communicatively coupled to the pressure-sensitive, multi-touch device and the display. The pressure-sensitive, multi-touch device measures a position at which one or more touches are executed on the pressure-sensitive, multi-touch device and, for each of the one or more touches, a force with which that touch is executed. The controller receives a touch report for each of the one or more touches from the pressure-sensitive, multi-touch device. Each touch report indicates the position at which that touch is executed and the force with which that touch is executed. The controller outputs to the display a pre-touch visualization command for displaying a pre-touch visualization. The pre-touch visualization is displayed at a location of the display mapped from the position at which that touch is executed on the pressure-sensitive, multi-touch device.

主权项

1. An apparatus comprising:
a display; a multi-touch device; a processor in communication with the display and the multi-touch device, the processor configured to:
receive a first touch report for a first touch executed on the multi-touch device, the first touch report indicating a position and force of the first touch;receive a second touch report for a second touch executed on the multi-touch device, the second touch report indicating a position and force of the second touch;filter the force of the first touch and the force of the second touch to ignore a momentary dropout of force caused by unintended force variation while dragging across the multi-touch device;if the force of the first touch is below a first non-zero force threshold, output a first visualization command to display a pre-touch visualization at a first location on the display, the first location mapped from the position of the first touch;if the force of the first touch exceeds the first non-zero force threshold, output a first touch input command to indicate the position of the first touch and decrease the first non-zero force threshold for return to pre-touch;if the force of the second touch is below a second non-zero force threshold, output a second visualization command to display the pre-touch visualization at a second location on the display, the second location mapped from the position of the second touch; andif the force of the second touch exceeds the second non-zero force threshold, output a second touch input command to indicate the position of the second touch.
