1. A method for initiating a touch interaction mode for a touch sensor, comprising:
receiving a first sense signal indicating a first touch attributed to a first touch entity;
receiving a second sense signal indicating a second touch attributed to a second touch entity;
responsive to determining that the first touch entity and the second touch entity form a common touch entity:
associating the first touch and the second touch with the common touch entity; and
enabling a common touch entity interaction mode of the touch sensor;
responsive to determining that the first touch entity and the second touch entity do not form the common touch entity:
associating the first touch with the first touch entity;
associating the second touch with the second touch entity, wherein the second touch entity is different from the first touch entity;
enabling a multiple touch interaction mode of the touch sensor; and
assigning a first touch group entity identifier to the first touch and a second touch group entity identifier to the second touch entity, wherein the first touch group entity identifier is associated with the first touch entity and the second touch group entity identifier is associated with the second touch entity;
receiving a third sense signal indicating a third touch attributed to a third touch entity; and
responsive to determining that the first touch entity and the third touch entity form a common touch entity, assigning the first touch group entity identifier to the third touch.
