Should I be able to dilate my pupils at will?
« on: 09/09/2009 20:05:49 »
Okay, so I've seen some interesting things about what others can abnormally do on this website, and I just registered and I have an awkward question. Is it normal for a person to be able to slightly control the size of their pupils on will? Anyone else have this? ???

We investigate consciously controlled pupil size as an input modality. Pupil size is affected by various processes, e.g., physical activation, strong emotional experiences and cognitive effort. Our hypothesis is that given continuous feedback, users can learn to control pupil size via physical and psychological self-regulation. We test it by measuring the magnitude of self evoked pupil size changes following seven different instructions, while providing real time graphical feedback on pupil size. Results show that some types of voluntary effort affect pupil size on a statistically significant level. A second controlled experiment confirms that subjects can produce pupil dilation and construction on demand during paced tasks.
