Inspired by the echolocation of bats, these glasses utilize a combination of hardware and software:
- Power Up: The user turns on the glasses, activating the built-in battery.
- Distance Adjustment: A small dial allows users to adjust the sensitivity of the ultrasonic sensors, tailoring the detection range to their needs.
- Obstacle Detection: Ultrasonic waves emit from the glasses, bouncing off nearby objects and returning to a receiver. The system calculates the distance between the user and the obstacle.
- Alert System: Upon detecting an obstacle, the glasses trigger a buzzer, alerting the user of potential hazards.
The current version of the smart glasses lacks an optimized power source and voice warning function, and their aesthetic design needs improvement. Future iterations will address these issues by incorporating voice and vibration warning functions and optimizing the power source for longer battery life.
