MUSICAL INPUT DEVICE AND DYNAMIC THRESHOLDING

摘要

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for detecting vibrations in one or more strings of a stringed input device, detecting contact between the string and a contact in an array of contacts. The contacts detected and the vibrations can be registered, processed, and interpreted as musical notes. In some embodiments, the vibration inputs are only registered if they are intended inputs rather than inputs caused by the mechanical coupling of vibrations across the strings.

主权项

1. A method of registering inputs in a stringed input device comprising:
detecting, with a first sensor, vibration in a first string; detecting, with a second sensor, vibration in a second string that is caused by a mechanical coupling of the vibration of the first string with the second string; determining a thresholding ratio describing a degree to which the vibration in the first string caused the vibration in the second string; detecting an additional vibration in the first string and an additional vibration in the second string; determining whether an amplitude of the additional vibration in the second string is greater than a dynamic threshold amplitude that is a function of additional amplitude of the first string and the thresholding ratio.
