Say hello to what is definitely the world’s most useless USB gadget. This vision and posture reminder glows and chimes if your head gets closer than 35 CM to your computer monitor. I guess this is useful if you have young kids that you’re tired of nagging about sitting too close to the computer. Otherwise it may win the Geardiary Most Useless Gadget of 2008.

Blue lights on means your head is positioned within recommended visual distance, i.e. 35 to 60cm from monitor. Red lights flash when your head is closer than 35cm from monitor, and means too close. USB Vision and Posture Reminder chimes to further remind you when you hold such improper gesture longer than 15 seconds.
