Artificial intelligence-based electric wheelchair control method and device and system therefor

An artificial intelligence-based electric wheelchair, comprising:

• a wheelchair frame;
• a plurality of wheels attached to the frame;
• a footplate attached to the frame;
• a display device;
• a steering joystick;
• a speaker;
• a lamp;
• a buffer;
• a communication board configured to enable the electric wheelchair to communicate with external devices;
• a display board;
• a sensor board configured to generate sensing information from signals provided by sensors of the electric wheelchair;
• a steering board configured to detect input from the steering joystick and to control steering of the electric wheelchair;
• a drive board configured to control a motor that drives one or more of the wheels;
• and
• an electric wheelchair control device operatively connected to the communication board, the display board, the sensor board, the steering board, and the drive board, and configured to control overall operation of the electric wheelchair,
• wherein the electric wheelchair control device is configured to:
• perform a booting procedure when power is applied to the electric wheelchair to pair the electric wheelchair with a user device;
• obtain user information from a server via the paired user device;
• determine an operation control mode of the electric wheelchair based on the obtained user information;
• recognize a predefined start command from a user via a corresponding sensor associated with the determined operation control mode while an always-on display (AOD) screen of the display device is in an inactive state;
• activate the display device from the inactive state to an active state in response to the start command and output a user interface screen on the display device for controlling the electric wheelchair, and then await a user input signal;
• perform a machine learning-based analysis on the user input signal received via the sensor to identify the user and perform user authentication;
• and
• when the user authentication is successful, identify a control command corresponding to the user input signal and execute the control command by controlling at least one of the drive board and the steering board to control movement of the electric wheelchair,
• wherein the user information includes at least one of impairment type information and health condition information.
