TITLE IoT-Based EOG Wheelchair with Fall Prevention Using ESP32
ABSTRACT We report the development of a gaze-driven, IoT-enabled smart wheelchair that addresses the mobility and safety needs of people living with severe motor impairments such as quadriplegia, ALS, spinal cord injury, and locked-in syndrome, by combining eye-movement control with real-time caregiver alerting and onboard fall prevention. The control architecture centres on an ESP32 microcontroller that acquires eye-movement signals through a minimal three-electrode arrangement (right, left, and reference), cleaned and amplified by the X-pill Bio Amplifier before analogue-to-digital conversion. Lateral gaze controls turning, a deliberate single blink initiates forward motion, and a rapid triple-blink sequence commands the wheelchair to halt. Forward obstacle sensing is handled by an HC-SR04 ultrasonic module paired with a local buzzer for immediate audio feedback, while an MPU-6050 six-axis IMU watches for dangerous tilt angles and free-fall signatures that indicate a patient fall. Propulsion is delivered by a pair of 12 V, 60 RPM gear motors controlled through an L298N H-Bridge driver. On detection of either hazard, the ESP32 pushes an instant alert to the caregiver’s smartphone via the Blynk cloud platform over the onboard Wi-Fi link. Bench evaluation on a scaled prototype demonstrated 93.75% command accuracy, complete obstacle and fall detection, and near-perfect alert delivery. Together, these capabilities form a low-cost, minimally invasive assistive device that gives severely paralysed individuals a realistic route to independent movement.
