Patent Images
1. A percussion controller comprising:
- an instrumented striker comprising at least one accelerometer, at least one angular acceleration sensor, and a wireless transmitter that transmits signals indicative of accelerations measured by the accelerometer and angular accelerations measured by the angular acceleration sensor;
a sensor-enabled striking surface comprising a resilient surface for striking with the instrumented striker and a plurality of sensors disposed beneath the sensor-enabled striking surface; and
a data processing system, wherein the data processing system;
a) predicts, based on information conveyed by the signals, at least one of(i) a force of impact of the instrumented striker on the sensor-enabled striking surface, and(ii) a location at which the instrumented striker will impact the sensor-enabled striking surface;
b) relates the location of impact to a musical event; and
c) generates a musical event message based on the musical event.

Abstract
A percussion controller comprises an instrumented striker including devices for obtaining inertial measurements and a wireless transmitter, a sensor-enabled striking surface that receives an impact from the instrumented striker, and a data processing system that receives the inertial measurements and predicts at least one of the force or location of impact of the instrumented striker on the sensor-enabled striking surface before impact actually occurs.

14. A percussion controller comprising:
-
an instrumented striker comprising devices for obtaining inertial measurements as the instrumented striker is moved and a wireless transmitter that transmits signals indicative of the inertial measurements; a sensor-enabled striking surface that receives an impact from the instrumented striker; and a data processing system that receives the signals and predicts, using inertial navigation techniques, a force and location of impact of the instrumented striker on the sensor-enabled surface before impact actually occurs and generates a musical event message therefrom.

15. A method comprising:
-
predicting a force of impact of an instrumented striker on a striking surface before the impact occurs; determining a location of the impact of the striker on the striking surface; relating the location of impact with a musical event; generating a signal that conveys information about the musical event; and transmitting the signal to a device that generates a signal that can be converted to sound that is related to the musical event. - View Dependent Claims (16)
