Meet the Gemio Band: a fun wearable device with light, motion, sound and proximity sensors that allows you to send others light messages. It has light effects that respond to music and people around you. Users can change their band in a snap.
The Gemio Band can be charged wirelessly. It has dual batteries and a magnetic dock. The companion app is available for iOS and Android devices. Gemio comes with common messages, but you can create your own light signals. Ships in November.
