The Control System Based on Extended BCI for a Robotic Wheelchair

The Non-traditional Methods of Robotic Wheelchair Multi-channel Control

“…Another non-traditional robotic wheelchair control method is the 'Extended BCI interface' concept [2]. This concept is based on the simultaneous usage of several non-traditional data channels (BCI, voice, gestures) to improve the control reliability.…”

“…According to [2], the 'Extended BCI interface' is a robotic control system based on a set of independently operating non-traditional control methods. When the operator uses more than one control method, it is necessary to decide which command to execute at this moment.…”

“…For such people, other (non-traditional) control methods based on robotic control methods are begin developed. Non-traditional control methods are based on the usage of special device that can receive various information from the patient [2]. These data can be interpreted into commands for controlling the robotic wheelchair.…”

Research on Home-Auxiliary Robot System Based on Characteristics of Human Physiological and Motion Signals

“…Take the elderly people with physical disability as an example: as they grow older, their limb movement becomes more and more difficult, which brings inconvenience to their life. To solve this problem, many researches have been carried out to use human physiological electrical signals to control auxiliary equipment to assist human life [3][4][5][6].Šumak et al successfully used eye wink, eyebrow motion, clenching of teeth, and smirk to control different functions of keyboard operation [7]. Fernandez-Fraga et al used different hand movements to achieve effective control of the cursor movement up, down, left, and right in the screen [8].…”

“…e BCI is a technology that directly reads brain information and identifies human intentions through modern mathematical algorithms, which makes it possible to directly use human brain signals to control external devices to serve human beings [3][4][5][6].…”
