gravitymax in transition

an interesting combination of natural and gestural input using sound waves. by scratching textured materials on surfaces such as table, wall or even your own thigh, a small sensor deciphers magnitudes and patterns into various input for devices. white paper available for download.

genius concept, execution, and storytelling.
wearable device + gestural input + augmented reality = intangible interface? o_O

i love looking up the latest gadgets and consumer electronics. but i am too cheap can’t afford to buy every shiny toy that’s out there. as my interests for nui experiments grow, i will need cheap hardware to play with. not too long i ago came across a few homemade multitouch pads and display blog posts. here’s a compilation of what i found. if you know of any other, drop me a note and i’ll add it to the list.

let’s start with the a super cheap one. you pay for what you get, but it works!

a nice one from instructables. the plexi alone will cost you some bucks, but it’s nothing compare to the real surface.

ideo labs’ version. hay look, here’s “some old projection surfaces” from storage we can use. how convenient. even better if you have a rear-projection tv.

and a few of links in one. this one includes an open source kit from cubit, which comes in a premade box, or ready-to-assemble basic components.
