1. A wearable gesture detector, comprising:
a wristband;
a plurality of pressure-sensitive conductive pads coupled to the wristband, the plurality of pressure-sensitive conductive pads being configured to detect epidermal deformations caused by muscular contraction or extension during a hand gesture, wherein the pressure-sensitive conductive pads are conductive and variably resistive;
a motion sensor configured to detect changes in orientation during the hand gesture;
a controller configured to collect hand gesture data samples based on the epidermal deformations detected by the plurality of pressure-sensitive conductive pads, the controller being further configured to collect hand orientation data in the form of quaternion samples based on the changes in orientation detected by the motion sensor;
a fabric layer covering the plurality of pressure-sensitive conductive pads causing the plurality of pressure-sensitive pads to be in indirect contact with a user's skin, wherein the fabric layer increases sensitivity to changes in capacitance resulting from epidermal deformations detectable by the plurality of pressure-sensitive conductive pads; and
a wireless transmitter configured to send the hand gesture data samples and the hand orientation data to a data utility device for additional processing, wherein the quaternion samples are converted into yaw, pitch, and roll information for the data utility device before or after transmission
wherein the additional processing further includes: determining a hand gesture based on the hand gesture data samples and the hand orientation data.
