Abstract: Systems and methods for proximity-based position, movement and gesture detection are provided that utilize capacitive sensor arrays. In one embodiment, the system utilizes textile-based capacitive sensor arrays that can be integrated into other textiles, such as clothing, bed linens, etc., or that can be integrated into the environment (e.g., furniture, wheelchairs, car seats, etc.). The system recognizes gestures from detected movement by utilizing hierarchical signal processing techniques.

Abstract: Systems and methods for distinctly detecting the movement of a first object and the movement of a second object relative to the first object are provided that utilize a capacitive sensor array and an inertial sensing system. The systems and methods are particularly suited for the detection and measurement of first body part movement (e.g., leg movement) and second body part movement (e.g., foot flexion). In one embodiment, the system utilizes a textile-based capacitive sensor array and one or more inertial sensors disposed on a flexible structure that is adapted to be wrapped around a body part, such as a leg. The systems and methods can be used to calculate periodic leg movements (PLM) and general leg movements (GLM) based on detected movements of the leg and foot.
