Multi-device multi-user sensor correlation for pen and computing device interaction

A computer-implemented process for initiating user interface actions, comprising using a computer for:

• concurrently sensing a first grip of a primary user on a touch-sensitive pen and a second grip of the primary user on a touch-sensitive computing device;
• concurrently with sensed first and second grips of the primary user on the touch-sensitive pen and the touch-sensitive computing device, sensing a third grip of a secondary user on the touch-sensitive pen and a fourth grip on the touch-sensitive computing device;
• correlating signals received from the concurrently sensed grips of the primary and secondary users on the touch-sensitive pen and the touch-sensitive computing device to determine a context of the grips;
• and
• using the context of the grips to initiate a command in an application executing on the touch-sensitive pen or the touch-sensitive computing device.

A system for finding meta information, comprising:

• a computing device;
• and
• a computer program comprising program modules executable by the computing device, wherein the computing device is directed by the program modules of the computer program to:
• concurrently sense a first grip of a primary user on a first touch-sensitive device and a second grip of the primary user on a second touch-sensitive device;
• concurrently with the sensed first and second grips of the primary user on the first touch-sensitive device and the second touch-sensitive device, sense a third grip of a secondary user on the first touch-sensitive device and a fourth grip of the secondary user on the second touch-sensitive device;
• correlate signals generated by the simultaneous contacts from the users on the touch-sensitive devices;
• determine a context of the simultaneous contacts from the users on the touch-sensitive devices based on the correlation of the signals;
• for each determined context, of a simultaneous contact, label the determined context of the contact as metadata for use in an application.
