About

Tharaka L. Dassanayake is a researcher at the forefront of non-invasive brain-computer interfacing (BCI), with a particular focus on developing practical, low-cost assistive technologies. His key research areas center on electroencephalography (EEG) signal processing and the application of steady-state visual evoked potentials (SSVEP) for real-world control systems. Dassanayake’s most significant contribution is his pioneering work on single-channel EEG SSVEP-based BCI for robot arm control, a breakthrough that dramatically simplifies the hardware requirements for BCI systems while maintaining reliable performance. This innovation, detailed in his highly cited 2021 paper (9 citations), demonstrates how a single EEG channel can effectively decode user intent to control a robotic manipulator, offering a more accessible and affordable solution for individuals with severe motor disabilities. His research directly addresses the critical need for user-friendly, minimally invasive BCI systems that require little to no training, making assistive technology more attainable. By proving that complex robotic control is possible with a streamlined, single-channel setup, Dassanayake’s work has opened new pathways for the development of practical, everyday assistive devices that can significantly improve the quality of life for disabled individuals.
