To detect your movements, we utilized an ultrasonic sensor. This sensor is able to quickly and accurately detect your body when you get close to it and immediately sends a signal back to the app.
Bright circular lights sit at the top of the device and light up to indicate which corner you need to ghost to.
The enclosure for the device is made specifically so it doesn't get destroyed easily. With rubber bumpers, the device can withstand a decent fall.
To power the device, we used long lasting li-po batteries. These batteries can last up to 10 hours of ghosting on a single charge.
