From Letters to Words: Efficient Stroke-Based Word Completion for Trackball Text Entry

Article presents a stroke-based word completion technique for use with the Trackball EdgeWrite text entry method, which had been constrained to character-level entry. Unlike most word-completion designs, which require users to select words from a list, this technique allows users to select words by performing a fluid crossing gesture. The result is a faster and less tedious method of trackball text entry for people who already use trackballs but cannot touch-type on a physical keyboard. Results from a study with an individual with spinal cord injury showed that stroke-based word completion provided a 46.5 percent increase in speed, a 36.7 percent decrease in errors, and a 43.9 percent reduction in strokes, compared to the subject's peak performance with the character level Trackball EdgeWrite.
