Multi-command Chest Tactile Brain Computer Interface for Small Vehicle Robot Navigation
This work addresses interactive robotic control for users, but it is incremental as it builds on existing tBCI methods with a new body location.
The study tackled the problem of robotic vehicle navigation by developing a tactile brain-computer interface (tBCI) using stimuli on five chest positions, achieving validation with five subjects and demonstrating feasibility through information-transfer rates.
The presented study explores the extent to which tactile stimuli delivered to five chest positions of a healthy user can serve as a platform for a brain computer interface (BCI) that could be used in an interactive application such as robotic vehicle operation. The five chest locations are used to evoke tactile brain potential responses, thus defining a tactile brain computer interface (tBCI). Experimental results with five subjects performing online tBCI provide a validation of the chest location tBCI paradigm, while the feasibility of the concept is illuminated through information-transfer rates. Additionally an offline classification improvement with a linear SVM classifier is presented through the case study.
