# Scientific Outreach with Teegi, a Tangible EEG Interface to Talk about Neurotechnologies

## TL;DR

Teegi is an interactive, tangible avatar that visualizes real-time EEG data to facilitate public understanding of neurotechnologies and brain-computer interfaces through direct engagement.

## Contribution

This paper introduces Teegi, a novel tangible interface that visualizes EEG signals in real time for effective scientific outreach and education on neurotechnologies.

## Key findings

- Teegi effectively demonstrates brain activity in real time.
- Users can interact with Teegi to learn about EEG and BCI.
- Teegi enhances public engagement in neurotechnology education.

## Abstract

Teegi is an anthropomorphic and tangible avatar exposing a users' brain activity in real time. It is connected to a device sensing the brain by means of electroencephalog-raphy (EEG). Teegi moves its hands and feet and closes its eyes along with the person being monitored. It also displays on its scalp the associated EEG signals, thanks to a semi-spherical display made of LEDs. Attendees can interact directly with Teegi -- e.g. move its limbs -- to discover by themselves the underlying brain processes. Teegi can be used for scientific outreach to introduce neurotechnologies in general and brain-computer interfaces (BCI) in particular.
