This is a quick look at TrackHat's solution to low-cost head tracking (https://www.trackhat.org/ My first experience with head tracking outside of VR, was Star Citizen's built in Faceware-integration. This however didn't work too well with my webcamera (Logiech C920), as it to me felt too sluggish, too light-dependent, and the camera's lack of working zoom, meant that it didn't work ergonomically with my chairmounted HOSAS setup. I looked at TrackIR's solution, but that fealt to expensive. As a middle ground, I stumbled upon TrackHat, a somewhat more reasonable priced complete solution using a modified PS3 camera and a hat outfitted with infrared LEDs. They also have a clip that can be mounted to a headset. Both the hat and the clip are available as wired or wireless (using rechargable battery pack). As I don't always play using headphones, I went with the hat. Due to the current pandemic situation, they have had serious delays. I ordered mine in the end of June, and they arrived last week. This is the downside of ordering from a tiny company like this. They did however keep me informed during the summer, and offered to refund the whole amount because of delays. The items were packaged safely, and a instruction booklet was included. This was good, as you need to tweak the camera's driver settings for it to work optimally. This is needed just the first time, but is a manual process nontheless. The included camera is a PS3-camera, modified to have it's IR filter removed. The resolution is 120hz at QVGA, which doesn't sound impressive, but works very well as it only needs to track some IR light sources. They included a 3D-printed monitor stand for the camera, but this was not working optimally for my monitor, and I fail to see how it would work well for anything other than notebooks. I have no problem with the part being 3D-printed, it's just not deep enough to solve the problem it claims to solve. In the end, I somehow found a way to get it working by weighing the cable down, but this part needs some serious redesign. The hat was comfortable enough. They claim 10 hours battery life, which is probably reasonable as it's just a battery pack with 3 IR LEDs. Also included was a micro-USB charging cable of reasonable length. The hat can be used while charging. The tracking software worked well enough. It's a modified version of opentrack, with some features removed. You can use the full opentrack-software instead if you're an advanced user. The tracking itself worked well. It feels smoth, but you have to be aware of other light sources. This is something that works best in a darkened environment. Not a problem for me, but something to be aware of. All in all, I'm pleased. I ended up paying 75 GBP, and now have a working head tracking solution. I've been told that delivery times are better now, but it's still something to be aware of. I've not had time yet to make any videos of it in practice, but for me it works well in both ED and SC.
