Abstract
Aphasia and other communication disorders affect a person’s daily life, leading to isolation and lack of self-confidence, affecting independence, and hindering the ability to express themselves easily, including asking for help. Even though assistive technology for these disorders already exists, solutions rely mostly on a graphical output and touch, gaze, or brain-activated input modalities, which do not provide all the necessary features to cover all periods of the day (e.g., night-time). In the scope of the AAL APH-ALARM project, we aim at providing communication support to users with speech difficulties (mainly aphasics), while lying in bed. Towards this end, we propose a system based on gesture recognition using a radar deployed, for example, in a wall of the bedroom. A first prototype was implemented and used to evaluate gesture recognition, relying on radar data and transfer learning. The initial results are encouraging, indicating that using a radar can be a viable option to enhance the communication of people with speech difficulties, in the in-bed scenario.
