Text entry by raising the eyebrow withHaMCoS
Torsten Felzer, Stephan Rinderknecht · 2014
This demo actually showcases not one but four different text entry methods for persons with very severe physical disabilities. All four rely on the same kind of input signals: tiny contractions of the brow muscle which are captured using electromechanical coupling. The input device involves a piezoelectric element which is attached to the user's forehead and kept in place with the help of an elastic sports headband. The switch-like signals are used in combination with the HaMCoS system - which allows to fully emulate a two-button mouse - and various auxiliary applications to enter text. This proposal talks about the input hardware in more detail and describes the text entry ideas shown in the demo.
