A touch interaction processing method, device, and system. The touch interaction processing method includes: receiving first information sent by an electromyographic signal collection device and second information sent by a location capturing device (101); if it is determined that a time gap between a first touch start time and a second touch start time is less than a preset threshold, and a quantity of touch points that is corresponding to a hand gesture is the same as a quantity of touch points that is included in the second information, generating a touch instruction, where the touch instruction includes a device identifier of the electromyographic signal collection device, the hand gesture, and coordinate information of each touch point (103); and performing an interaction operation corresponding to the touch instruction (105).
