Personally, I have long been interested in all sorts of new items in the field of information input or computer management. It seems to me that the fact that the main input tools remain the mouse and keyboard for half a century is a blatant injustice. If the neural interface (to my great regret) is still far away, then various multi-touch displays are already being produced and prepared for mass production.
And today I discovered a very interesting, in my opinion, concept developed by two designers Eun-Gyeong Gwon and Eun-Jae Lee (I was afraid to transliterate their names). They called their creation “I (eye) Contact”.

This device is designed to replace the mouse and become an alternative to cursor control. The idea seems to be taken from the military, who use similar technology in combat aircraft for quick targeting. The device consists of two main parts: a contact lens and a transmitter, which is also a container for storing this lens. Further, I think the essence of the work is clear: we dress the lens, it tracks the movements of our pupil and sends a signal to the transmitter, and he in turn sends the signal to the computer and moves the cursor.

Handsomely? Full The truth of the practicality of this technology can be questioned. Here immediately there are also problems of a multiuser mode, from the point of view of hygiene and convenience. And the need for periodic replacement of lenses. And how will the lens receive energy? But the most interesting for me is the question of "click". I can hardly imagine how this can be realized, except with a blink ... but it seems to me that you can’t last like this for a long time =) I would love to see how these designers would play something like diablo, where especially gifted produce more than 300 clicks in a minute
But in any case, the idea is interesting and fully deserves attention, especially in specific areas. And I sincerely hope that new ideas in data entry will appear further and more often.
