If deaf people could be discreetly be alerted of people approaching them from behind they would be startled less often.
Proof of Concept
An Arduino (in this case a Sparkfun RedBoard Edge) connected to a human sensor to detect humans, a motion sensor to know when the person wearing the device is moving (to ignore humans while in motion to prevent false positives), and a vibration motor to silently alert the wearer of the device that someone is coming. By putting this all in a small case that clips to the back of someone’s belt, it should provide some warning of approaching humans.
I'm a recovering engineer + sales guy...
BSEE from UMD 2004, and then 15 years of working with signal processing, AV, control systems, networking, and other gadgetry (mostly B2B). Now I'm in the Master of Human-Computer Interaction program, graduating in August 2020.
I have pretty solid experience with:
- rs232/422/485/midi/dmx protocols
- sketchup and other cad tools
- music (mostly guitar, but others too)
- general troubleshooting
- networking (wired + wireless)
- signal processing
- streaming video/audio
I have some experience with or am mediocre at:
- laser cutting
- reverse engineering
- ML (none really but I'm currently in a class)
- rusty with C++ and Java, but used to be decent
- tube amplifiers
