Recently, due to improvement of touch screen technology, various pen-based input devices and related electronic products are developed accordingly. Users can enter data by a stylus without memorizing large amount of symbols, positions or word decoding methods in advance.
Firstly, performances obtained from various pen-based input devices were studied. Besides the traditional pencil-and-paper input method, the results showed that the performance obtained form tablet PC is the best. Literatures have shown that the size of stylus has significant influence on its input effectiveness. The cross-section of stylus used with PDA has significant influence on its effectiveness as well but the discussion of the cross-section of stylus used with tablet PC is hardly found. Thus, the main purpose of this research is to study the various cross-sections of stylus used with tablet PC and its performance on text and graphic input. Thus 6 styluses with different cross-sections and a pencil were chosen to conduct the experiments. Their performances were evaluated and compared in terms of the total writing time, error rates, total drawing time and drawing stability. Also, the level of holding comfort will be rated.
20 subjects were recruited to conduct the experiment. The collected data were analyzed by one way ANOVA with blocking design or Friedman test based on their normality. The results showed different cross-sections of stylus do not significantly affect the error rates, and total drawing time. However, no matter in the part of pencil and paper or in the part of stylus used with tablet PC, cross-section with round shape has the best performance in total writing time and the one with oval shape has the best drawing stability. In regard to the level of holding comfort, the best is the one with hexagon shape. It is expected that the findings of this research would be good references in designing pen-based input devices to enhance their input performance.
