Accomplishment: Settled on the text-to-speech (TTS) engine to convert the OR model’s output into speech dictation should the user use that setting. The TTS engine we will be using is espeak, with the wrapper library pyttsx3 that will provide additional functionality such as adjusting the rate and selecting voice. Also looked into integration of the speech module into the overall device.
Progress: Given the design changes we made, to use the NVIDIA Jetson and forgoing the network-based approach, I believe I am back on track with my progress.
Projected Deliverables: I will next begin researching and developing ways in which to implement the vibration module of our device, which involves the ultrasonic depth sensors that will feed data into a program, which is eventually routed to the vibration motors. This program will act as a mediator between the depth sensors and the vibration motors, allowing us to set a specific threshold for detecting objects (2m for example), along with determining the frequency of the vibrations. I will likely be working alongside Meera, who leads the hardware for the project, towards implementing this module
