Project name
Aperiodic visual stimulation in a VEP-based BCI
Project short description
Visual-evoked potentials (VEPs) are a possible way to drive the a Brain-Computer Interface (BCI). This projects aims at maximizing the discrimination between different stimuli by using numerical codes derived from techniques of digital telecommunications.

Start date: 2009/10/01

Laboratory work and risk analysis
(work in progress) Several EEG sessions will be recorded. Data acquisition is performed at the IIT-Lab. All risks are those related to the use of video terminals and EEG devices.
- 2010/04/12: First data acquisition session
- 2010/04/16: Second session
Part 2: project description
What this project means to demonstrate is the possibility to extend the SSVEP paradigm to multiple visual signals (i.e. blinking lights) using a numeric encoding, in a way similar to what has already been attempted with noise-tagging.
