Meet the Unitact Bracelet: a smart wearable device designed for people dealing with hearing impairment. It has buttons and vibrators, allowing users to stay connected. Each vibration has its own rhythm and strength and can be linked to a message or activity.
Unitact grabs your attention with vibrations around your wrist. It also has a notification LED to let you know when you have a new message. More information is available on Kickstarter.
