How awesome of a proof of concept is this? An app for the iPhone which allows you to type by measuring the vibrations of you tapping around the phone. Designed by Florian Kraeutli, a student at Goldsmiths, this program is called Vibrative, and you train it to measure the vibrations caused by tapping on a false keyboard near the iPhone itself.
Unfortunately, it’s only around 80% accurate right now, due to the limited sensitivity of the accelerometer. Said Kraeutli:
“The signals I’m collecting are very weak…At the moment it’s more of a proof of concept but if you made the accelerometer more sensitive you could improve the accuracy quite easily.”
I can’t imagine it’d be very comfortable to type for a long time on a hard surface like that, and the sub-optimal accuracy requires an auto-correction feature in order to have it make sense. However, it really shows how many interesting ways we have yet to explore the capabilities of the iPhone. I’m sure you could prop the iPhone up on a keyboard, train it using the app on that, and use that combo as a way of making a more comfortable variation.
