Amulet is a wearable product that we developed at Nokia Research in 2011. The bi-static display is always-on, and normally shows the most recent activity. The data radio polls every minute for new notifications, feeds, IM, and social updates. The BT radio supports incoming/outgoing calls and music playback. A 3D accelerometer measures activity. The form factor mimics the 2011 Nokia Lumia handset series. We now own the Amulet IP.
