Will Iris Scanner ever work in Sunlight?

[swanlee]

The iris scanner has gotten better over the last year but I still can't get it to work in direct sunlight. Do any other eye technologies like this work in sunlight? Any chance it will get tweaked to work?

It is unlikely without a complete technology change. It is an infrared camera, and sunlight is made up of crazy amounts of infrared light. Because of the same, the kinect does not work in direct sunlight. I have been able to use it (the iris scanner) sometimes but it is always unlikely in sunlight. I guess it depends on how the sun hits you. You could try using your head to block the sunlight hitting the camera and your face directly, but no promises.

NO, the iris-scanner was a big mistake. Holding it close to your eyes in public is just ridiculous. Not mentioning that it is not made for sunlight.

besides the sunlight thing, it's pretty cool. I like it.

I actually use it all the time. It's quite cool. Sometimes, I go straight for the pin input, but most of the time I use the scanner.

It is not just the sunlight problems. Try unlocking it right after you wake up or the middle of the night. In the morning my eyes are to -_- for scaner to work and in the middle of the night they are to -_- due to, to much light from the screen. -_-

^agreed. I've experienced that, as well.
