The Denso Corporation has created an electric ring named Yubi-nya that can be used as a remote control. Wearers of the ring can operate devices and control remote processes by just pressing two fingers together. The ring produces a weak electric current that is conducted outwards through the user’s index finger. When the tips of the finger and the thumb are brought together, the current travels back around through the hand to the ring and activates  a radio signal that’s sent out to a remote device.
Denso has demonstrated the device as a control for opening and closing the door of [...]

Elizabeth Goldring of MIT is working on a device that may help certain legally blind people see. In some cases of blindness, a functional retina is hidden behind cloudy lenses which block any kind of clear vision. Doctors currently use a large, and very expensive device called a scanning laser opthalmoscope, which can temporarily focus an image on these hidden lenses, allowing people to temporarily see. Goldring’s device replicates this process on a much smaller scale, using a hacked together combination of a digital camera and a color LED back-lit LCD screen. She’s been working on this portable SLO for [...]
