Some technical propositions for electromyographical human interface device

Abstract

Recognition of gestures is an actual and important problem. This technology can be applied in various fields of human activity: management of computers and household appliances, creating a natural human-machine interfaces for the deaf, the manipulation of three-dimensional models of objects, virtual reality applications, management of quadrocopters and exoskeletons. The purpose is to analyze of existing technical solutions of the implementation of human interface device, identification of deficiencies of these devices, as well as offer some technical solutions to address these deficiencies. The work is based on the method of surface electromyography. Technical solution for the implementation of the device, based on the detection of electromyographic signal, taking into account the position of the object in space, is proposed, structural and functional schemes are developed. This device is supposed to implement on the base of Wi-Fi technology network. To reduce the energy consumption it is necessary to use energy-efficient software algorithms. The proposed implementation of the human interface device has no shortcomings of analyzed analogues: a wired connection between the segments, the presence of a reference electrode. The prospect of research is optimization of the gesture recognition algorithms, testing of these algorithms, studying of the possibility of simultaneous repetition of movements, definition of the limits of speed and number of degrees of freedom of movement.
