ABSTRACT
In this paper we present Stroke++, a novel hybrid Chinese input method for touch screen mobile phones that leverages hieroglyphic properties of Chinese characters to enable faster and easier input of Chinese characters on mobile phones. By using a special keypad layout, a friendly user interface and an adaptive radical selection algorithm, we achieved a competitive inputting performance compared with currently prevalent mobile Chinese input methods, while keeping a low entry barrier for Chineseinput novices. An extensive evaluation results show that Stroke++ out-performs the state-of-the-art keystroke-based or handwriting recognition-based Chinese character inputting methods, as far as the input speed and convenience are concerned.

Stroke++: A new Chinese input method for touch screen mobile phones
Over the past few decades, users have been feeling clumsy inputting Chinese on mobile devices, partly because the layout of the keyboard/keypad is originally designed for inputting Latin alphabets. To improve this user experience, we propose Stroke++, a ...
A semantic analysis of Chinese radicals
One of the most significant features of the Chinese language is that it displays a considerable amount of semantic information at the radical (components comprising Chinese characters) level. Chinese radicals show the important semantic impacts on ...
An efficient accessing technique of Chinese characters using Boshiamy Chinese input system
IRAL '00: Proceedings of the fifth international workshop on on Information retrieval with Asian languagesIn this paper, a new efficient technique for Chinese character retrieval is proposed. This technique designs a minimal perfect hashing function based on the Chinese remainder theorem for a simply and widely used Chinese input system called Boshiamy ...
