Vibrative virtual keyboard by Florian Kräutli
“Touch screen devices, such as smartphones, lack a suitable method for text input which can compete with mechanical keyboards. The Vibrative Virtual Keyboard aims to appease the frustration felt by smartphone users when faced with drafting lengthy e-mails or notes on a small onscreen keyboard.”
The phone picks up vibrations from his fingers as he taps on invisible keys on the table. Using an app called Sensor Monitor, Krauti can pick up and measure those vibrations using the iPhone’s accelerometer, a sensor built into the phone.
