文字・図形情報入力速度の面から見たタブレットPCにおけるペンインタフェースの評価

抄録

Nowadays, many college students possess PC as an educational study tool. However, PC is hardly used for taking notes of a lecture. The main reasons are as follows (a)a text input speed at which the student unfamiliar with a keyboard operation, is slow. (b)In an ordinary PC with keyboard and mouse, it is difficult to input figure information. It is expected that the input of a figure and/or character is easy for a tablet PC with a pen interface, and it is suitable for the tool taking notes of a lecture. In this paper, comparative evaluation of a tablet PC and an ordinary PC was carried out from the viewpoint of the input speed of figure and/or character information. In the experiments, we measured an input-speed of following 3 items: (1) input speed using an ordinary PC with keyboard and mouse, (2)input speed using a tablet PC with the pen interface, and (3)speed of handwriting on a paper. The speed of handwriting on a paper can be regarded as an input-speed of ideal pen interface, so we measured not only the input speed of a tablet PC used in the experiments, but also the input speed of ideal pen-interface.
