Abstract
We designed and evaluated a Huffman base-4 Text Entry Glove (H4-TEG). H4-TEG uses pinches between the thumb and fingers on the user´s right hand. Characters and commands use base-4 Huffman codes for efficient input. In a longitudinal study, participants reached 14.0 wpm with error rates <;1%. In an added session without visual feedback, entry speed dropped only by 0.4 wpm. Yet another session was added that required entry of text with punctuation and other symbols. Entry speed dropped by 1.5 wpm.
