System for hand gesture detection

Abstract

A system for hand gesture detection is provided, comprising: a wrist wear adapted to be worn about a wrist of a user of the system and including a set of skin electrodes adapted to face the wrist; an impedance measurement circuit adapted to measure at least a first impedance in a first portion of the wrist and a second impedance in a second portion of the wrist which second portion is circumferentially displaced in relation to said first portion, wherein the first impedance is measured via a first electrode group including four skin electrodes of said set of skin electrodes and the second impedance is measured via a second electrode group including four skin electrodes of said set of skin electrodes, and a processing circuit adapted to detect a hand gesture of the user based on the first and the second impedance measured by the impedance measurement circuit.
