Title: Eyes-Closed Brain-Computer Interface

Speaker : Prof. Han-Jeong Hwang (Dept. Medical IT Convergence Engineering, Kumoh National Institute of Technology)

Date: Mar. 13 (Mon.), 2017

Time: 05:00 PM 

Location: Woo Jung Information & Communication bldg., Room 601

Hosted by Dept. of Brain & Cognitive Engineering, Korea University / Institute of Brain and Cognitive Engineering, Korea University / BK21+ Global Leader Development Division in Brain Engineering, Korea University / Interdisciplinary Major in Brain and Cognitive Science


A brain-computer interface (BCI) is a communication method that translates brain signals into commands for controlling external devices. It can thereby provide an alternative communication channel for severely paralyzed patients, such as amyotrophic lateral sclerosis (ALS) patients. So far, various BCI paradigms have been introduced to develop practical BCI systems, such as motor imagery, event-related potential (ERP), steady-state visual evoked potential (SSVEP) and so on. However, because patients with neurodegenerative diseases who are the main targets of BCI technology gradually lose their motor functions, including decline of visual functions in progressed states of the disease, these patients cannot take full advantage of the conventional BCI paradigms requiring moderate eye movements. In this presentation, I will introduce recent BCI studies based on new BCI paradigms that can be used in eyes-closed condition. I will wrap up the talk with the discussion on challenges and opportunities with the future BCI technology that can be used for paralyzed patients in daily life
