Good review, thanks for sharing.
Have been using a Tobii Eye Tracker 5 since mid December; six months. I haven't played with the settings very much, and only in SC's menus. Didn't touch the curves or settings in the Tobii software at all yet - didn't need to. I found I like to only keep head tracking on, and disable eye tracking, because I find that quite distracting. It feels like I'm not using the tech to it's fullest potential - the eye tracking really does work very well and very consistently, but head tracking alone does everything I wanted it for. I especially find little circular overlay spot thing (often red in the video review above) hugely distracting - you don't have to use that if you don't like it! Also, for SC, I only have the head tracking enabled during flight. Tried it for FPS, and found that fun for a bit, but then too distracting and disorientating. I turned it off for FPS for now.
I also used Track IR before that. I liked Track IR, but it is a hassle to deal with the hat and wire clip thingy, and my goodness the IR sensor for that gets
hot!
The Tobii works
very well, and you don't have to wear a hat or anything reflective for it to work. I wouldn't be without it now, it's fantastic, it just works, and it hugely improves immersion and ability to see around me in space for all sorts of manoeuvres (docking, mining solo in a Mole to line up a rock for the turret, combat).
Some thoughts after some extended use:
- It comes with a 1m cable fitted, and also consumes a fair bit of power, for a USB device. This means it doesn't work well (or at all) with a USB extension cable. :( The FAQ and instructions tell you to plug it directly into a USB socket on your PC. However, my monitor is on a sit-stand desk, and the computer is ~2m away along the cable path. However, I bought a powered USB hub. It works perfectly with that. (Except perhaps...)
- When I first start my PC, it doesn't always power up the Tobii Eye tracker, and so when you start the Tobii Experience software, the tracker is not found (it's off). By unplugging it from the USB hub and plugging it in again, it works every time. This may or may not be caused by the powered USB hub, but I 100% need that. It's not such a big deal.
- Sometimes it gets misaligned or miscalibrated while you're playing, usually when I've been doing something else, and looking elsewhere for a bit and its 'gradual recentering' has drifted my detected head position somewhere weird. Occasionally it becomes disabled in-game when you didn't touch a key. Simple solution: press / above your numeric keypad to disable it, which instantly centers your view, then press / to re-enable it, which starts head tracking nicely centered again. That sorts out most issues I've had with head tracking during play, and it's also perfect to...
- Disable head tracking while you are mining in a Greycat ROC. This might be a bug in the game (and maybe it's fixed already), but with head-tracking enabled, your head steers the mining laser, instead of your mouse! That's no good. As above, press / on the numeric keypad to temporarily disable head tracking while cracking rocks and collecting the gems in your ROC, and turn it on again when you've collected them all. Easy. (There is no such issue when mining with the Prospector or Mole).
- The curved monitor mount has velcro pads that are pretty robust, but still failed after ~5 months of me knocking my sensor by accident when I reached for something else under my monitor. When they failed and left the Tobii sensor dangling at the wrong angle, I just removed them from the monitor and from the mount thingy with some solvent and a fingernail, and then stuck the mounting bracket directly to the underside of my monitor with some very sticky 3M adhesive foam pads. It's now closer to my monitor and sticks out less far, so I knock it less often, and it's very strongly held. And, if those pads ever fail too, I have about 99 more.
It's a fantastic product! Worth it if you can afford it.
