Why not? Such as? Sometimes it's just fun to make something, avoiding it just because said thing already exists in some form is silly.

I mean, completely ignoring prior researches can be a bit disingenuous.

Why? I'm supposed to avoid projects just because someone else did a similar thing unless I want to delve into their research or something?

I can do whatever you want with my own projects, if I want to make an app to do X thing I can.

Wouldn't it be better to use head tracking to get the position of the head relative to the monitor, so the monitor behaves like a window? Like in Johnny Lee's classic Wii demo [1]. The way it currently works (rotating the view upon head rotation) doesn't really make sense because a monitor is not a head mounted display. 1: https://youtube.com/watch?v=Jd3-eiid-Uw

I loved that demo, but the problem with "monitor as a window into the world" is that monitors are relatively small and people don't sit very close to them. The FOV you obtain with most setups is disappointingly small. You need to be relatively close to a large display for it to work well. It's one of the reasons why the idea never took off in the first place, I think.

Cool to see this, it's a cool in-between step for not having additional wraparound screens or a VR headset. I used to run a similar software[1] for when I was really into playing F1 racing games. However one of the problems I found was the initial disconnect in your head and eye movement that took some getting used to. For example, if you want to look left to see an upcoming turn, naturally your eyes move before your…

just wondering, did this difference in looking around mess you up at all when driving in real life

opentrack would be the one to beat these days: https://github.com/opentrack/opentrack It's completely replaced my TrackIR 5, since it averts the need to wear headphones and dig out the tracking bracket every time I want to use it, and the accuracy feels about the same. I found head tracking pretty much becomes second-nature after a while - to the point at which it feels weird to play first-person sims without it. Not…

Do you really prefer webcam + opentrack over the trackir? Asking because I literally have a trackir on the way to me in the mail, and most discussions I could find were at least 2-3 years old.

I have had a TrackIR 5 since pretty much release which I used religiously for flight siming. I also have a tobii eye tracker. I have pretty much stopped using the trackir entirely now in favour of the eye tracker + opentrack. It is incredible, works flawlessly. You have a very small amount less horizontal turn tracking, but honestly your head has to be comically side on for you to notice the difference. Perfectly smooth and predictable. Lately been using it in Nuclear Option and it’s changed the game. TrackIR also works great, and is also flawless, but the key difference is the eye tracker requires zero hardware on your head to work. Even works through glasses.

But doesn't it make you look away from the monitor? Unless you have this 45 inch curved monitor really close to your face?

It requires robotics monitor arm

Are you serious? That's not the cheapest setup then. Would be better to buy a VR goggles in such case

I second how awesome head tracking is for simming. Feels somewhat natural after a short adjustment period.

Last time I tried it there were still some problems (combinations of face pitch adjustment and z-axis translation resulted in weird camera movements in-sim IIRC) that makes me hesitate to call it fully natural, but some of it could probably be a filtering/configuration issue.

It's also fully possible TrackIR suffers from the same issue!
