MULTI-DEVICE MULTI-USER SENSOR CORRELATION FOR PEN AND COMPUTING DEVICE INTERACTION

摘要

A grip of a primary user on a touch-sensitive computing device and a grip of a secondary user on the touch-sensitive computing device are sensed and correlated to determine whether the primary user is sharing or handing off the computing device to the secondary user. In the case of handoff, capabilities of the computing device may be restricted, while in a sharing mode only certain content on the computing device is shared. In some implementations both a touch-sensitive pen and the touch-sensitive computing device are passed from a primary user to a secondary user. Sensor inputs representing the grips of the users on both the pen and the touch-sensitive computing device are correlated to determine the context of the grips and to initiate a context-appropriate command in an application executing on the touch-sensitive pen or the touch-sensitive computing device. Meta data is also derived from the correlated sensor inputs.

1. A computer-implemented process for initiating user interface actions, comprising using a computer for:
receiving sensor signals representing a grip of a primary user on a touch-sensitive computing device; receiving sensor signals representing a grip of a secondary user on the touch-sensitive computing device at a time proximate to the received signal for the grip of the primary user; correlating the sensor signals for the grips of the primary and secondary users to determine the context of the grips; and using the context of the grips to initiate a command in an application executing on the touch-sensitive computing device.
