After acquiring the opinions of some visually impaired people and experts, I decided to modify the product. Products will have the following features:
- There are 4 ways to use "Bracelet for the blind"
- The product can be combined with a stick. (The combination of "Bracelet for the blind" with the stick will be the most effective solution.)
- The obstacle detection distance can be configured between 2 meters and 5 meters (distance is configured by push button).
- Will only use a vibrating motor on any finger. The vibration of the motor will gradually increase as you approach the obstacle.
- Can be combined with an external power source to increase the use time of equipment to many days.
