Finally setup my EyeX after having it sit around for a week.
Unfortunately, despite what ObisidanAnt said about his 21:9 monitor, it does not seem to work well on mine. My monitor is a 29" 2560x1080 display (PB298Q); hell it might even be the same one he uses.
The center of the screen and about 10cm out from the device seem to work okay, but beyond that the tracking is just completely scrambled. I try to do the calibration test and it's just going crazy when looking at the circles on the sides of the screen. I cannot get an accurate reading no matter my sitting position (or how wide I open my eyes).
Ontop of that though, there is a very clear delay (latency) on updates. Seems to be around 50-75ms. While I didn't expect it to be instantaneous, I expected it to be faster than it is.
It's also not as precise as I expected, though they do mention that the accuracy is about the size of a thumb. Oh well.
Overall, I'm a bit let down.
Improving the update rate is probably impossible without vastly increasing the cost, but as for the tracking on bigger monitors, it shouldn't be too hard to just extend the PCB and space the sensors further apart, right?
Hoping to see a revision of the device for displays bigger than 27".
All that said, I've not tested it in any games yet, but if the calibration test is reporting badly like that, I don't have much hope. Going to try The Division with its native Tobii EyeX support.. will
(possibly) update later. (Probably won't be testing E
until 2.1 is out.. which got delayed; ugh.)
