The maker Daniel Ramsgard has created a unique pair of glasses called ‘Sonic Sensitivity’. The Sonic Sensitivity is an audio assistive eyewear for the Deaf and Hard-of-Hearing individuals. Sonic Sensitivity will help them by using voice-to-text conversions, bridging the communication gap between the hearing-impaired and those around them. The hardware consists of popular Atmega328 microcontroller along with 1.51” Waveshare Transparent OLED display for the visual aid and Elechouse 3.1 VR module for voice recognition. He has used a system of lenses along with the transparent OLED module to make display is readable.
The firmware part of the project is bit complex to explain, but it follows the general structure of initializing the TOLED, VR module, and commands. The commands are the heart of Sonic Sensitivity's functionality. The user can program their own command for better and easier experience. Seven commands can be loaded at once but a number of them can be programmed. You can find the whole code for the project at his GitHub repository.
