Integrated Biomedical System Laboratory3Demand on the healthcare
system rises in proportion to the aging population. Technology can
fill in the supply gap by providing automated systems to augment
healthcare services.For rehabilitation, the small inertia-based
sensors could help improve healthcare delivery.

Laboratory?4Sensing user movement may not be sufficient. Feedback
from therapists also plays an important role in informing patients
of their progress leading to better chances of recovery .
The optimized design combination of inertia sensors and
vibrotactile feedback to correct arm posture is the main
contribution of this paper.
