Abstract

A spurious input detection system includes a touch input display, a touch input surface, and a non-transitory, computer-readable medium. The non-transitory, computer-readable medium includes instructions that, when executed by a processor, provide a spurious input detection engine. The spurious input detection engine is operable to receive a first input from the touch input display and a second input from the touch input surface. The spurious input detection engine is further operable to determine that the first input is a spurious input based on a combination of the first input and the second input. The spurious input detection engine will cause the first input to be disregarded in response to determining that it is a spurious input.
