On-line personalization of a touch screen based keyboard

摘要: The user expectations for usability and personalization along with decreasing size of handheld devices challenge traditional keypad layout design. We have developed a method on-line adaptation touch pad keyboard layout. starts from an original monitors the usage by recording analyzing keystrokes. An learning algorithm subtly moves keys according to spatial distribution In consequence, matches better users physical extensions grasp device, makes trajectories during typing more comfortable. present two implementations that apply different vector quantization algorithms produce adaptive visual feedback. Both qualitative quantitative results show changes in are consistent, related user's handedness hand extensions. testees found positive. can either be applied keyboards or ergonomics research
