Identifying Device Associated With Touch Event

An apparatus comprising

• a touch sensor;
• and
• one or more processors coupled to the touch sensor and configured to:
• determine a first context data associated with a first touch event detected by the touch sensor;
• receive from a second device a second context data associated with a touch event on the apparatus, the touch event having been detected by the second device;
• compare the first context data with the second context data;
• and
• determine, based on the comparison, whether the first touch event is the touch event detected by the second device.

One or more non-transitory computer-readable storage media embodying logic that when executed by one or more processors cause the one or more processors to perform operations comprising:

• accessing a first context data associated with a first touch event on a first device;
• accessing a second context data associated with a touch event on the first device, the touch event having been detected by a second device;
• comparing the first context data with the second context data;
• and
• determining, based on the comparison, whether the first touch event is the touch event detected by the second device.
