Numerous studies have utilized alphabetic writing for subject matter. However, few have addressed visual processing of Chinese characters in the left midfusiform gyrus. OBJECTIVE： To verify visual processing of Chinese characters and images in the left midfusiform gyrus using functional magnetic resonance imaging. DESIGN, TIME AND SETTING： A blocked design paradigm study. Experiments were performed at the Room of Magnetic Resonance, Guangdong Provincial Second People＇s Hospital, China from May to June 2009. PARTICIPANTS： A total of eight undergraduate students were recruited from Guangzhou University of China, comprising two females and six males, aged 20-23 years. The subjects were right-handed which was determined by a Chinese standard questionnaire. None of the subjects had a history of psychoneurosis, familial disease, color blindness, or color weakness. METHODS： A total of eight undergraduates were enrolled as subjects. Picture-naming and verb generation tasks were employed through the use of functional magnetic resonance imaging. Analysis of Functional Neurolmages software was used to process the data. MAIN OUTCOME MEASURES： Visual processing of Chinese characters and images in the left midfusiform gyrus was measured. RESULTS： Picture-naming and verb generation tasks were shown to significantly activate the bilateral midfusiform gyrus. Activation occurred in the visual word form area of the left midfusiform gyrus. CONCLUSION： The left midfusiform gyrus plays a general role in visual processing of Chinese characters and images.展开更多

SAMis excelIent as a model for generating Chinese characters, but it is difficult todetermine appropriate parameters because the use of calligraphic knowledge isneeded. By noticing that calligraphic knowledge of calligraphists is includedin their corrective actions, we adopt a strategy to acquire calligraphic knowl-edge by monitoring, recording and analyzing corrective actions of calligraphists,and try to realize an environment under which calligraphists can easily makecorrections to character forms and which can record corrective actions of cal-ligraphists without interfering with them. In this paper, we first construct amodel of correcting procedurcs of calligraphists, which is composed of typicalcorrecting procedures that are acquired by extensively observing their correc-tive actions and interviewing them, and develop a form-correcting system forbrush-written Chinese characters by using the model. Secondly, through actualcorrecting experiments, we demonstrate that parameters within SAM can beeasily corrected at the level of character patterns by our system, and show thatit is effective and easy for calligraphists to be used by evaluating effectivenessof the correcting model, sufficiency of its functions and execution speed.展开更多

Reflecting the spe-cific hierarchical relations among radicals and strokes of Chinese characters,the proposed data structure is based upon a character model that can generatebrush-written Chinese characters on a computer. Through evaluation experi-ments using the developed system, it is shown that representation of calligraphicknowledge and form evaluation of Chinese characters can be smoothly realizedif the data structure is utilized.展开更多
