A new device for insomniacs lulls users to sleep through a mimicked swaying sensation. This non-invasive, non-pharmacologic sleep aid stimulates the vestibular nerve via small headphone-like attachments that sit behind your ears while you rest. Through human factors research and successive rapid prototyping efforts, we developed ear pieces that are lightweight and comfortable. The electronics are housed in a small case with tactile buttons designed to be easily distinguished in the dark. A simple user interface on the back-lit display allows users to adjust the intensity and duration of perceived motion.
