i have eyetribe and they suffer from a major accuracy problem when moving you head backward or forward (if you move 2 inches backward or forward, the tracker on the screen moves in x and y by one inch) – so how does the eyeX compares to eyetribe as far as precision is concerned ?
thank you.04/05/2015 at 18:02 #2930
so nobody can tell me if the eyex is sensitive to user head positionning on the z axis (moving toward or away from the screen by a few inches) ? thank you08/05/2015 at 15:52 #2951Jenny [Tobii]Participant
You can use the EyeX Controller with maintained accuracy when moving your head along all axes (x, y, z) as long as your eyes are visible to the eye tracker and within the so called track-box (the volume the eye tracker can track eyes within). This gives a freedom of movement of up to about 7-10 inches from the center of the track box, a point about an arm’s length from the center of the eye tracker front panel.13/05/2015 at 23:43 #2970
for your tobii pro tracker serie you deliver accuracy data such as http://www.tobii.com/Global/Analysis/Training/Metrics/Tobii%20X2-30%20Eye%20Tracker%20Accuracy%20and%20Precision%20Test%20Report.pdf
why don’t you have a similar document for eyeX ? it makes us very suspicious about your accuracy.
