Lab day 1

Eye Tracker:
It was a tiring experience. It took fair amount of time to realize that only one of my eye was being tracked. I went through the calibration procedure twice. I did not understand how it worked though. I tried doing some simple task with the device. One task was to use it as a mouse. I tried navigating around the screen and clicking on an icon. I could not navigate as i intended to. I could not select any icon on the screen. It was difficult to avoid jitter and concentrate on the same area.
I found difficulty in holding the pointer to one area. It was interesting to see the recognition of the eye from the software and i missed noticing lot of parameters it calculated.
i think the device can be used to the context or roughly the area the user is gazing at.

Head mounted display:
The device reminded me of the night vision goggles that i often see on movies. It was cool . It had displays in front of the eyes and a camera in front to capture the images in front. There was control box which controlled the display input. It can be used to relay the video captured by camera or can be enhanced I did not find much of difficulty in using it. Josh conducted an user study with the device. The tasks we were asked to do were interesting. Arranging books sitting and standing, writing, reading and walking around the room. Well the task helped me adjust to the difference in the depth perceived through goggles. May be with greater usage the user might get adopted to this difference.
