what eye tracking is a new field and eye tracking will change the future,Today，some thousands of eye trackers out there globally.But imagine 10 or 20 years,eye track in every car,in every laptop,and sooner or later eye tracking in will enter your home,At the beginning we knew we want to build a 300 Eye Tracker,a 300 hertz because it it allows so many more things to see in the result. This opens up Complete new fields like when you wanna measure how fast was a certain moving from point a to b, when did the blink start when the blink stop,Or even for head movement were exactly where the pupils located at each point in time.well,there's basically nice tracking these three parts.There's the physical part,How good are the cameras,How good is the image，How good are the illuminate as how good a picture you start with.Then, It's the math, taking the image, finding what you want, finding the pupil,finding the gleam, finding the angles, and calculating a raw data,And then the 3rd side of it is what you do with the raw data,How do you filter it.How do you presume where someone actually is looking finding where are the eyes in the box and so on?In this project we started making more extensive tests，So we made the different illumination sets to verify that we have stable and accurate tracking all over the box.And with all your environment settings and also with different gaze angles people with lenses and glasses and.they always have been a fast eye trackers, but they squeeze the respondents into chin rests, Very narrow,So the respondents has to be in this small box cannot move,And then of course you can question is my test valid, would behave like this .Or did the respondent only behave like this.Because it was squeezed in this small chin reason.It was not allowed to move .TX300 allows the respondents to move freely around.We work quite hard of making sure that the user shouldn't be affected by the new technology. All it should see all the users to see is just a better product ,Works better more accurate. And it's easier to use than anything else ,available.That's been our aspect. We don't show off the technology.the results the measurement results the eye tracking results should speak for themselves.But that's the way technology. Is It's I'm quite proud,I wouldn't say it if I didn't mean it.But this is basically good.
