Brain-computer interfaces (BCIs) bridge the brain activity to external systems in order to enable the control of external devices or the communication with others just by thoughts. Among various types of BCIs, non-invasive BCIs harness the brain activity measured on or outside the scalp without intracranial penetration. In the past decades, non-invasive BCIs have advanced to make it possible for people to use BCIs in practice. However, there still remain a wide range of issues in order to deploy non-invasive BCIs to the users at home for daily use, from the sensing of brain signals to the user experience of BCIs. This talk will present our recent efforts to address some of these issues when people use a particular type of BCIs based on event-related potentials (ERPs) of electroencephalography (EEG). Participants in our studies use this BCI to control home appliances such as TV, electronic light, door lock, air conditioner and so on. We have investigated potential effects of a number of internal and external factors on BCI performance, which is likely to occur in daily use at home. The factors considered in out studies include changes in emotional states, the posture of users and visual stimulation environments. I will discuss how these factors affect the operation of BCIs for home appliance control and other factors we will investigate in the future to enhance the practicability of our BCI system.
