Have you ever looked at your iPhone and thought “I wish my keyboard was invisible”? Me neither. But before anybody does, I can tell you that a student at the University Of London has managed to create a piece of software that uses the iPhone’s accelerometer to read particular vibrations that correspond to a certain key.
The student managed to do this using a jailbroken iPhone 4 and a piece of paper with a keyboard printed on to it. The iPhone learns each different key be reading certain vibrations strengths when the keys on the paper are touched.
The Telegraph spoke to the student:
“The signals I’m collecting are very weak,” said Florian Kraeutli, a computing student at Goldsmiths, who created the system as part of his work on user interfaces.“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.”
