Pranav Mistry’s cool input devices

This new video about [Pranav Mistry's] SixthSense project doesn’t bring us much that we haven’t seen before. At least, not on that project. What really caught our eye was the device he shows off at the beginning of the video. Using two old ball mice, he constructed a grip style input device. It is simple and elegant and we can definitely see using this in future hacks. Not only is it cheap and apparently effective, it seems as though it could be constructed in a very short amount of time. all you need are the wheels that spin when the ball moves, 4 springs and some string. Why didn’t we think of that?

EM Brace for sensing magnetic fields

Juan Aguilar — Fri, 20 Jun 2008 04:20:00 +0000

We’ve discussed the notion of using machines to add or improve sensory input to the body before, and we’ve found another project with the same idea. [Nick Hasty] has developed an object he calls the EM Brace, which allows the user to sense electromagnetic fields with a wave of the hand.

The device works by connecting two antennas to an enclosure that contains a speaker. The enclosure is intended to be worn on the back with a harness securing it in place and wrapping the arms around the wearer’s body. The antennas are incorporated into a pair of gloves. When the antennas pick up electromagnetic radiation, the speaker emits a low frequency sound waves. They vibrate the enclosure and the arms, which in turn vibrate the body, signaling to the wearer that he or she is in an electromagnetic field, also referred to as hertzian space. A good deal of detail about the project can be found on his blog, or if you prefer, download his thesis paper in(PDF).

Wearable haptic devices bestow sixth senses

Juan Aguilar — Sat, 14 Jun 2008 03:30:00 +0000

Engadget recently posted a story about a flexible tactile display that can be wrapped around any part of the body and give haptic feedback to the user. The research team from Korea’s Sungkyunkwan University that developed the device are focusing on applications like Braille for the visually impaired or transmitting tactile data to a remote user, but this is just the beginning; the applications for wearable haptic feedback are wide open.

The Feelspace tactile compass is a good example. It is little more than an electronic compass hooked to array of vibrators arranged along a belt, but it allows the wearer to know which way is north at all times by pulsing only the northernmost vibrator. It’s intended to be worn at all times, so it creates a sort of directional sixth sense for the user without the need to constantly check a device. If they are able to reduce the size of the housing unit and combine it with these new displays, it could be worn inconspicuously under clothes.

If you want more native superpowers, body modder [Steve Haworth] has a solution. By implanting a silicone-coated neodymium magnet into the fingertip, the owner of the implant becomes capable of sensing magnetism with a degree of sensitivity unattainable by simply holding a magnet. One person who had the magnet implanted reported feeling magnetic sensors at a library and feeling the location of a motor in an electric can opener six inches from his hand.

We’re always curious about input fed to the body by worn or implanted devices, and with these advances, the notion of data and sensory integration is almost a palpable reality. Pun intended, but can you blame us?
