Hi,

 

Have you ever wanted to play simulator games, and look around without having to switch between mouselook and aiming? Well, with this handy guide you can make your own headtracking device!

 

I've been thinking about this idea for a while, and finally I've come around to building and using a DIY Head Tracking "device".

The device is a simple 3-point tracker, which software like FreeTrack uses to calculate the position and rotation of the head of the wearer.

The LEDs must be in specific locations for the FreeTrack software to work. The LEDs MUST be installed in the same figure as mine.

The offsets can be modified inside FreeTrack, so you can place LEDs further or closer to the center as you wish.

All that is needed outside of the Wiring, is a webcam with a low res. (800x600 is enough).

I've made a schematic in paint, which shows how everything is connected, and which Resistors and LEDs should be used.

Note: I'm using Red LEDs in the above picture, due to IR LEDs not being available in the shop near me at the moment..

I will not be writing a lengthy FreeTrack tutorial, as there are many, many of these on youtube.
