Teegi: Tangible EEG Interface
This addresses the challenge of public engagement with complex neurotechnology, though it is incremental as it builds on existing tangible and augmented reality methods.
The authors tackled the problem of making brain signal data accessible to novice users by developing Teegi, a tangible EEG interface that combines spatial augmented reality, tangible interaction, and real-time neurotechnologies, resulting in a system that users found easy, motivating, reliable, and informative in an exploration study.
We introduce Teegi, a Tangible ElectroEncephaloGraphy (EEG) Interface that enables novice users to get to know more about something as complex as brain signals, in an easy, en- gaging and informative way. To this end, we have designed a new system based on a unique combination of spatial aug- mented reality, tangible interaction and real-time neurotech- nologies. With Teegi, a user can visualize and analyze his or her own brain activity in real-time, on a tangible character that can be easily manipulated, and with which it is possible to interact. An exploration study has shown that interacting with Teegi seems to be easy, motivating, reliable and infor- mative. Overall, this suggests that Teegi is a promising and relevant training and mediation tool for the general public.
