Fresh hacks every day
Eye tracking is a really cool technology used in dozens of fields ranging from linguistics, human-computer interaction, and marketing. With a proper eye tracking setup, it’s possible for a web developer to see if their changes to the layout are effective, to measure how fast someone reads a page of text, and even diagnose medical disorders. Eye tracking setups haven’t … Read the rest
This is a great hack, and it’s an advertisement. We wish this were the norm when it comes to advertising because they’ve really got our number. Skittles enlisted a few engineers to build a web interface that moves robot-powered candies.
When we started looking into this we figured that a few robots were covered with over-sized cases that looked … Read the rest
[Bruce Land], professor at Cornell, is a frequent submitter to our tip line. Usually he sends in a few links every semester from undergraduate electronics courses. Now the fall semester is finally over and it’s time to move on to the more ambitious master’s projects.
First up is a head-mounted eye tracker, [Anil Ram Viswanathan] and [Zelan Xiao] put … Read the rest
[John] has been working on a video-based eye tracking solution using OpenCV, and we’re loving the progress. [John]‘s pupil tracking software can tell anyone exactly where you’re looking and allows for free head movement.
The basic idea behind this build is simple; when looking straight ahead a pupil is perfectly circular. When an eye looks off to one side, a … Read the rest
[Luis Cruz] is a Honduran High School student, and he built an amazing electrooculography system, and the writeup (PDF warning) of the project is one of the best we’ve seen.
[Luis] goes through the theory of the electrooculogram – the human eye is polarized from front to back because of a negative charge in the nerve endings in the … Read the rest
The folks at Waterloo Labs have delivered a quite amusing project where they built a system to control Mario with eye movements. Unlike the other eye movement systems we’ve seen that use imaging to detect where you are looking, this one is using electrodes on muscles in your face. Not only do they supply a fairly amusing video, … Read the rest
The EyeWriter is an open source eye tracking initiative. This is the mature version of the KanEye project we covered in April. Collaboratively developed by Free Art and Technology (FAT), OpenFrameworks, and the Graffiti Research Lab, they seek to aid a friend of theirs who suffers from the degenerative muscle disease ALS.
They’ve come a long way … Read the rest
