I made the first usable version of this device earlier this month. Here is the main work:
Enclosure iteration: After having the headphone slot removed, I 3d printed the whole device. And I did some additional aesthetic work. After learning about the need for dark glass lenses for some visually impaired people, I wanted a pair of dark glass lenses for my device. But after asking the opticians and getting rejected, I used several layers of overlapping black cellophane glued into the grooves originally reserved for the lenses for aesthetic purposes.
The increase of the remote control function: I purchased an IR single button remote. When I made the choice of the purchase, I took into account that the visually impaired might want a remote control with a good grip and tactile feel to the button. So in the end, I went with this remote that has a round pie shape and a large button area. I changed the key value represented by the only button on the remote on my laptop to the "R" key, the key value defined in the program that triggers the voice announcement function. I plugged the matching IR receiver into the Raspberry Pi motherboard and it worked. All the user has to do is press the key and the voice announcement is heard.
The shooting of display material: Thanks to my friend (花兔仔) for modeling.
In the future, time permitting, I plan to:
optimise the device's appearance by integrating bone conduction headphones into the sunglasses.
add Chinese voice packs to adapt to China's market demand.
customise a PCB board to reduce the size of the motherboard so that it can be integrated into the sunglasses.
Enhance interactivity by taking into account the position of the user's limbs relative to the object.
