Wearable Camera with Haptics
Haptic response for visually impaired people
Haptic response for visually impaired people
Overview:
Wearable Camera with an low resonance actuator that provides haptic response for visually impaired people to safely cross sidewalks!
Description:
This project allows an array of 91 Ultrasonic Transducers (TCT40-16T) arranged in a hexagonal pattern to transmit a 40khz directional sonic beam, modulated using software-based FM, which will demodulate upon hitting a target, resulting in the sound appearing to originate from the target.
Features:
Compute: ESP32 S2-Solo microprocessor (I2C using SCL and SDA pins/I2S for camera)
Power: 3V3 LiPo battery via JST connectors
Sensor: OV7670 camera for image detection
Actuation: LRA (low resonance actuator) for haptic response
