What’s that?

‣ Originally, just a north-sensing “hat”

‣ Final version: a direction-sensing helmet‣ real time direction feedback through vibration

‣ head mounted device

What we learned

✓ Inadequate horse power in Arduino Uno• extremely hard to manage 2 software serial connections while

controlling vibrators and computing angles..

✓ Magnetometers are funny beasts• the one in the ArduIMU was probably defective, the external

standalone one was not precise enough to be of any use

✓ 360 degrees don’t fit in a byte• bugs can hide everywhere on an 8bit microprocessor

Future development

magnetometer yaw drift correction

better vibration patterns

multiple simultaneous feedbacks
