Research puts finger on virtual iPhone button

Research puts finger on virtual iPhone button: "Now researchers are using tiny vibrations to imitate the feel of a button when a user touches the keypad. The user will be able to feel the edges of each key so will be able to identify where each key is without checking visually.

Researcher Eve Hoggan, from the University of Glasgow’s Department of Computing Science, said: “We found that, compared to a standard keyboard, touchscreen keypads were less accurate in terms of text input. Without being able to identify through touch when a key had been selected there was a significant increase in errors made. When in a rush it can be very time consuming to check each character has been entered correctly and is particularly difficult when travelling. Feedback through the finger is more natural and the brain can process it faster than visual feedback. By providing tactile feedback we will bring the iPhone keypad close to the performance of a real physical keyboard.”"
