SSVEPを用いたブレイン・ロボット・インタフェース

抄録

In this research, we develop a BRI based on Steady-State Visually Evoked Potentials (SSVEP). We apply this BRI to a tele-presence robot system. The user puts on BRI to provide information to the system, and the robot presents choices to the user only when the decision is necessary for selecting the destination or the person to talk with. The BRI overlays options on the camera images captured by the robot and estimates which choice the user is looking at. According to the user's choice, the robot moves toward the destination or the person automatically so that the user can control the robot without continuously watching the screen to provide user inputs. We implemented the entire tele-presence system and confirmed the system works properly through online experiments. Moreover, we used a gaze input device as an alternative input device to BRI, and compared the usability.
