A DIY Mobility Aid for the Visually Impaired

The Haptic Vision Assist, by Colonel Panic, a DIY project designed to aid visually impaired individuals in navigating their environment. The device employs micro-controllers, infrared lasers, and haptic feedback mechanisms. This tool is developed to assist in navigating environments where obstacle detection and avoidance are crucial. The core of the device is built around three M5stickCplus esp32 modules, each integrated with infrared time of flight laser sensors. These sensors are strategically positioned on the wearer's clothing using magnets and Lego mounts, allowing for adjustability and ease of use.

The Haptic Vision Assist is engineered to translate distance data from the sensors into tactile feedback through vibration motor modules. The device features a face obstacle detection module, worn on the chest, to alert users to head-level obstructions, and two ground obstacle detection modules positioned towards the ground for lower body navigation. Users can calibrate the device to their specific environment, and the system is designed to alert wearers of potential ground-level hazards like steps or declines through a distinct vibration pattern. Additionally, the device provides battery level information through vibrational signals, adding to its practicality. This submission, currently in its prototype phase, reflects a blend of practical design and technical proficiency, with future plans to incorporate advanced features like object recognition and GPS navigation, indicating a commitment to enhancing the utility and user experience of the Haptic Vision Assist.
