Adaptation of a low cost motion recognition system for custom operation from shrink-wrapped hardware

Abstract

A low cost, embedded, reconfigurable device for motion detection of kinetically challenged persons has been developed. This paper presents the methods by which the device can be adapted to individual user's needs. The accelerometer data inputs are processed by the determination of the dominant axis of each motion, and by the determination of thresholds and delays that can be used to customize the system to individual needs. The resulting system is a highly adaptable input device which maintains the low cost constraints of less than $70.
