Smokescreen was a wearable device that assisted the visually impaired, created for the DVHacks II hackathon.
The user would wear the t-shirt the device was attached to to start. The device, with the help of a camera and machine learning software, identified objects in the surrounding area and gave haptic and auditory feedback to the user.
The primary interface for this was an Android phone, which communicated with a Raspberry Pi (for the camera). We were able to create a prototype that semi-worked.
While we didn’t win any prizes, it was a unique and interesting experience building a wearable device.
