UK student creates iPhone virtual keyboard using nothing but the accelerometer

The Telegraph is reporting that UK student Florian Kraeutli has created a virtual keyboard for the iPhone using nothing but the phone`s built in accelerometer.
"The system, dubbed Vibrative, uses the three-dimensional accelerometer in Apple’s smartphone to measure the characteristics of each tap on the table, such as the strength and frequency of the vibrations it causes, and compares them to “training data” to work out its approximate location.
The location is converted into a key press on the "virtual keyboard". Currently, the system determines the intended key correctly about 80 per cent of the time, so the data is also fed into an auto correct dictionary to ensure the words are spelled correctly."
