PC3: Myo, Myself and I: Utilizing Myoelectric Data in User Interfaces for Hand Prostheses and beyond

Description

The course will make participants feel like a cyborg in controlling systems with their muscle signals. Participants will construct their own user interface which analyzes muscle signals (myoelectric signals) to infer the user’s intended command in real time. Such user interfaces become increasingly important in medical research where they promise to let amputees control prosthetic devices intuitively and rapidly: users can just think of a movement, thereby creating a muscle signal, which is interpreted by the user interface to generate the desired action of the prosthesis.

During the course, participants will be provided with the necessary basic knowledge, programming tools, and myoelectric sensors to build a myoelectric user interface. Attendees are free in their choice of software project, but a simple basic project will be provided (controlling a basic 2D video game). We kindly request that participants bring their own laptops and download the required software before the course as described at https://techfak.uni-bielefeld.de/~bpaassen/ik2018.html.

In more detail, the sessions will cover:
1. An introduction to myoelectric user interfaces, with a focus on prosthetics research, as well as some basics in signal processing and the use of machine learning approaches for such user interfaces. The session will also be used to form work groups of participants.
2. An introduction to the specific tools used in the course and some first steps in building the projects.
3. Further work on the projects.
4. Display session for the resulting user interfaces.

We are excited to give this course and are looking forward to your participation :)

Objectives

The course aims at providing participants with a first glance into the engineering of myoelectric interfaces, which will require interdisciplinary knowledge in the application domain, classic engineering techniques such as signal processing, as well as machine learning. Participants will also extend their ability to work in interdisciplinary teams and produce rapid prototypes.
