The PupilWhat is it?The pupil is an opening located in the center of the iris of the eye that allows light to enter the retina.

It appears black because most of the light entering the pupil is absorbed by the tissues inside the eye.

In humans the pupil is round

The image of the pupil as seen from outside the eye is the entrance pupil

The hole does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea.

The PupilHow it worksThe iris is a contractile structure, made up of smooth muscle.

Light enters the eye through the pupil, and the iris regulates the amount of light by controlling the size of the pupil.

The iris contains two groups of smooth muscle -circular group called the sphincter pupillae, which constricts.

-a radial group called the dilator pupillae, which dilates

The pupil dilates in extreme psychical situations (e.g., fear) or contact of a sensory nerve, such as pain.

The Task-evoked pupillary response is the tendency of pupils to dilate slightly in response to loads on working memory, increased attention, sensory discrimination, or other cognitive loads.

The PupilInfrared exposureExposure to intense optical radiation can lead to the development of infrared cataracts. But the intensity for damage to occur must be very high.

Researchers investigate the importance of the wavelength of optical radiation in i.r. cataract formation through the temperature rises induced in the eye by monochromatic (invisible spectrum) optical radiation.

Cataracts is a clouding over the eye with varying degrees of obstruction of the passage of light.

It also can be cause by other things such as: Prolonged ultraviolet exposure Exposure to radiation Diabetes Hypertension Advanced age Severe trauma

Overall Infared should be harmless at the levels we’re using it.

- Line of Sight - infrared Eye Tracker

We talked about those annoying motion sensors before. So If eye trackers are placed around the sink strategically then the water should stay on while your looking at your own hands.

I was just thinking how much we come in contact with along the street. Then filtering through the things that could be adapted to use tracker technology. For example controlling the lights for pedestrians. Of course the tracker would need to be in a place so that drivers’ eyes can’t be tracked.

This was just one i had to propose. I hate having to ever touch the toilet in public bathrooms. Especially the disgusting seat rim. Whether you pick it up or put it down. What if we just had a gaze trigger that lifted and lowered the seat. I don’t know about you but using my foot is getting old.

Philly is trying hard to get its act together and the solar compactor trash cans are good steps. But those things aren’t even a year old and they already have become dirty enough to not want to touch them. So what if you just blinked at the door and it opened. And it runs on solar power so if it catches random blinks no biggy!

These are very quick illustrations to get the point across. My basic thought process was where do you not want your hand to be? Or where can it not be? If the hand can’t do it then they eye should be able to.
