I am not working in the industry but my related field is vestibular rehabilitation. Currently, the focus of the field is toward automated systems and incorporating VR into physical rehabilitation. On the software side, the devices are made so that it relies on as little on human/physicians input as possible. Deep learning/AI are introduced to make the rehab tasks personalized to specific patients at a specific progress. About the “hardware” aspect, the devices are made incorporating VR so that patients can use these phone-sized devices at home or at doctors’ clinics.
