An impact location and amplitude sensory system is provided. Such an impact sensory system may be useful in conjunction with gaming, education, as a control and feedback mechanism for virtually any surface. One embodiment of the impact sensory system may include at least one sensor and a signal processor. The sensor(s) may couple to the object. Sensors may include any of microphones and accelerometers. The sensor(s) receive an impact wave from an impact to the object, either as a propagating acoustic wave or as a traverse phase shift in natural oscillation. The sensor(s) may generate an impact signal in response to the sensed impact wave. The signal processor may couple to the sensor(s). The signal processor may include a preamplifier, an impact triangulator, and an outputter. The impact triangulater may identify a location of the impact from the impact signals. The outputter may then output data regarding the location of the impact.
