Immediate user performances with touch Chinese text entry solutions on handheld devices

ABSTRACT

"Immediate usability" is more important for mobile text entry solutions [7]. We compared immediate user performance of four touch Chinese text entry solutions on mobile devices including two Chinese handwriting recognition (HWR: full screen and 3-box) and two pinyin virtual keyboard (VKB: consonant plus vowel and QWERTY) solutions with novice users. It was found that users make more errors with Chinese HWR solutions than VKB solutions although there are no significant differences between the two solutions in each category. Users are significantly slower with the consonant plus vowel pinyin keyboard than the other three solutions although the consonant plus vowel keyboard is better on the measure of key stroke per character (KSPC).
