Proceedings of the Thirteenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XIII August 1-4, 1998, Sheffield, UK. pp. 67-82.
The influence of various parameters on the design of selection strategies was investigated. Our question is, do changes in the size, distance or direction to a target affect the differences in performance between selection strategies? We performed an experiment on a pen-based system to evaluate the effect of size, distance and direction on six strategies for selecting a target. Three target sizes, three pen-movement-distances, and eight pen-movement-directions were applied to all six strategies. The results show that the differences between selection strategies are affected by target size (when target size decreases below a certain size, differences between selection strategies appear; conversely, differences between selection strategies disappear when target sizes are increased beyond a certain size). The results also show that the differences between selection strategies are not affected by pen-movement-distance and pen-movement-direction. Issues relating to the merits of individual strategies will be the focus of planned future investigations.

In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 68-73.
This system assigns information in the form of correct answers to strokes of ink data, for simplifying the development of recognition and segmentation algorithms. When performing recognition and segmentation experiments using these algorithms, such correct answers (assigned by using our system) are utilized in speeding up these experiments and in enhancing their accuracy. In this paper, we first describe this system and its working, then we explain the correct answers actually assigned and the method of assigning them, and lastly we mention the experiments that we conducted assess this system.

Krishnan, S. Navaneetha and Moriya, Shinji (1993): Segmentation of Handwritten Text and Editing-Symbols from Ink-Data. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 1010-1015.
This paper proposes a real-time algorithm for segmenting handwritten text and editing-symbols from ink-data. This algorithm simplifies the development of "mode-less" editors for pen-based computers. Such editors enable users to create documents by writing characters and editing-symbols side-by-side (i.e. in "mode-less" fashion), and then executing the editing-operations corresponding to these editing-symbols. The proposed algorithm uses a segmentation decision-tree, and does not require a character-recognition dictionary. Using this algorithm, we segmented handwritten text and editing-symbols from ink-data (written by twelve writers) with an average segmentation accuracy of 97%.

Ren, Xiangshi and Moriya, Shinji (1993): The Minimal Sizes and the Quasi-Optimal Sizes for the Input Square During Pen-Input of Characters. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 1028-1033.
In this paper, the authors focus on the precise and minute operation of the tip of the pen of pen-based computers. As the first step, we focus our attention on minute operations that users make when writing characters. In doing so, we attempt to experimentally determine the followings: (i) what is the smallest possible size of the characters or symbols when they are written on the input screen of writing-tablet? (ii) the quasi-optimal sizes of the input square for characters. In this paper, we determine the above two by targeting three kinds of characters: (a) numbers, (b) small English letters, (c) capital English letters. From our experiments, we were able to determine the minimal sizes (i.e., the width and height) of the small English letters, capital English letters and numbers. We also obtained the preliminary approximation of the quasi-optimal sizes (i.e., the width and height) of the square enclosing the above three kinds of characters.

Moriya, Shinji and Taninaka, Hiroshi (1993): Concept of Minute Operation and its Application to Pen-Based Computers. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 1034-1039.
As compared to conventional computers, pen computers are being steadily miniaturized and are also becoming more portable. As a result of this, the display area as well as the writing area in such computers is getting smaller. In this context, the tip of pen is capable of very fine (i.e. minute) movements. The authors believe that, the above two factors motivate the creation of a pen-input interface in which such minute pen-movements are used to accomplish tasks such as writing, pen-gestures or scrolling. Pen input can accomplish various operations such as pointing, writing, recognition, gestures, scroll, etc. In this paper, we put forward a method of achieving these operations using the minute movements of pen tip. We call this proposed method as "minute operations." In this paper, we describe the characteristics, associated problems and applications of these minute movements.
