Why spend the effort messing around using a Wiimote-like remote, or even shouting at the TV, to get it to change channel, when you can just stare at what you want and blink to select? Well, that’s Haier’s theory anyway, and, amazingly, it actually works.
OK, so eye-tracking is nothing new — the military has been doing it for ages in helicopter gunships and things — but to see it genuinely working on a TV is pretty impressive. Well, I say on a TV, it’s not like it’s built right into the frame or anything. You’ve got an eye-scanning box that sits pretty close in front of you, which hooks into a computer to control the on-screen display. It’s certainly not the most convenient, practical or elegant solution, but hell, it’s a start, and it’s really just a prototype at this stage.
After calibration, watching a ball move across the screen while it tracks your eyes, you’re in. You focus on something to highlight it and then blink a couple of times in rapid succession to select it, moving through the menus. Navigating around by just looking at things was amazingly intuitive; you’re going to look where you want to click anyway, I guess, so this just removes a layer of apparatus and effort needed. Looking at the bottom pops up your standard media-playing bar, with volume options and play controls. Scrubbing, at least clicking and dragging, is a no-go though, but the rest works as you’d expect.
In my play with the thing, it was amazingly accurate, really; at least as precise as a Wiimote pointer, which was pretty impressive. The system struggled with those wearing glasses, but what do you expect?
It’s not practical in any sense of the word, of course — what happens when you just look at a specific spot on your TV, like tracking lap times while watching F1 for instance? Still, it could be pretty awesome in combination with voice control. Here’s hoping eye-tracking and Kinect combine to make channel surfing even lazier than it already is.














Creepy potential, as shown in a scientific test many moons ago, where a laser based eye tracker was used to monitor where a test subjects eyes wandered when viewing photos of a room full of people.
As you can imagine, females of the species tended to look at male behinds (this is ONE of their favourite male body parts apparently – other than the obvious, so get on that tread mill guys!), and of course, us guys eyes wandered towards the milk production units on the females in the scene.
(Assuming a hetro test audience of course.)
The privacy implications of a CONNECTED version of something like this is worrying. Effectively, ones ‘viewing’ habits could be monitored, exposing oneself to blackmail or public embarrassment if eyes wander in a direction they are not ‘supposed’ to wander!
The best use of the eye tracker is the work on peripheral vision, and testing how monocular visual field defects translate to binocular fields of vision. When you analyse how long it takes for someone with a defect to identify a hazard for example, its pretty scary seeing how their eyes have to scan so hard just to find it. Enough to drive anyone into public transport
This would last a few minutes in my house, as my constant staring and consequential replaying of anything involving Holly Willoughby’s Tits would upset the Wife a tad…
