Description

A BCI system is a communication system which monitorizes brain activity and translates specific features of the reflected signals by the user in command's intentions. BCI application will be based on sensorimotor rhythms, more specifically rhytms µ (8-12 Hz) and β (16-24 Hz). In this project the design, development and assessment of a training tool for BCI systems is suggested. This systems are based on motor imagination (MI-BCI), with the aim of making sensorimotor rhythms easier to learn, and so making every kind of MI-BCI application more user-friendly, regardless of their purpose, to encourage autonomy and improve the quality of life of people with severe motor disability. For that purpose, five different tasks are suggested. Each of them presents a progressive difficulty for the user according to the applicant company’s criteria. This way, the level of difficulty may be adapted to every user’s needs and progress. The suggested tasks, ordered from high to low according to their difficulty, are: 1. Movement imagination. 2. Modification of an object’s color. 3. Movement of a 1D cursor. 4. Puzzle resolution. 5. Avoiding obstacles game. Additionally, there will be a real-time visual feedback displaying the training process, which will allow the user to modify their brain activity according to the results obtained each time.
