Abstract

The Virtual Hyperbolic Keyboard (VirHKey) is a text entry method that was originally designed to be used with a stylus. We constructed and tested a keyboard-based version of VirHKey. Average text entry rate ranged from 5 wpm during the first 20-minute session to 21 wpm during the 20th session. The average character error rate was under 2%. VirHKey is unlikely to be the most efficient method on any input device. Its value lies in the ability to transfer text entry skill between input devices.
