KUMASHIRO Tomonori, YAMATO Masatake, MONDEN Akito, MATSUMOTO Ken-ichi, INOUE Katsuro

Technical report of IEICE. HIP 99 ( 722 ) 37 - 44 2000.3

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

The aim of our study is to make current GUIs more effective for computer users. This paper proposes an eye gaze interface in which computer users use both their eye and hand in doing GUI operations. We have chosen "drag-and-drop" operation, which is one of a daily-use operation, for this study. In our method, drag-and-drop operation is separated into three basic operations:(1) rough cursor movement toward the icon, (2) cursor adjustment onto the icon, and (3) pushing the icon. We use eye movement for (1), and, a mouse for (2) and (3). We also propose three adjustment method for (2):Auto, Manual, and SemiAuto. The result of an experiment to evaluate our method showed that the proposed interface augmented by SemiAuto adjustment is more effective than the conventional mouse interface.

PRODUCT FOCUSED SOFTWARE PROCESS IMPROVEMENT 1840 140 - 153 2000

Language：English Publisher：SPRINGER-VERLAG BERLIN

This paper proposes a model of successful maintenance that can represent how maintainability of each software module changes as it ages. We found that some of the metrics, measured from 20 years old system, fit our model; i.e., values of those metrics seem to be proportional to the degree of maintainability. We described each metric's critical line - a value that can be used for deciding whether a module should be re-engineered or not. We also described the interpretations on how each software metric relates to maintainability.

84 73 - 78 1999.8

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

The purpose of this research is realizing a more efficient input interface by using a look and a mouse together. As the first step, the button selection operation on GUI was divided into "operation (move operation) of moving cursor onto a button", and "operation (push operation) of pushing a button", and the method that performs move operation by the look and performs push operation with a mouse was examined. It became clear that cursor movement by the look is high speed, and it is more efficient than the selection operation only by the mouse as a result of the experiment. However, when the area of the button used as an operation object was about 1 square centimeter, it became clear that it is difficult to move cursor onto a button only by the look, and the mechanism, which assists move operation, is required.

An Analysis of Task - and Information - Sharing in Collaborative Debugging by Two Person

Morisaki Shuuji, Ito Atsuo, Monden Akito, Matsumoto Ken-ichi

IPSJ SIG Notes 1999 ( 40 ) 35 - 40 1999.5

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

Software debugging is often performed by more than one programmer working together. The goal of this research is to identify a model of how two person collaboratively perform a degugging task on a single program. Based on empirical studies we have conducted, we have identified patterns in task- and infromation-sharing, and applied them to analyze the ovserved collaborative debugging processes. The following two collabration patterns were found to be effective in degugging (1) one concentrated on a debugging task while the other collected potentially useful information about the program, and (2) the two shared one program source file in their editors instead of using duplicates and wrote comments iinto the file.

An Experimental Evaluation of 2-Person Debugging

ITO Atsuo, MORISAKI Shuuji, MONDEN Akito, MATSUMOTO Ken-ichi, TORII Koji

Technical report of IEICE. KBSE 98 ( 636 ) 45 - 52 1999.3

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In this paper, we evaluate methods for sharing debug activity and exchanging knowledge about bug, aiming at reducing debugging time, when two persons modify the same bug cooperating. Four experiments that two person detect and modify single bug are conducted to reveal effective methods. An experiment indicates that taking either task of: (1)exploring the bug location in the source code, and (2)understanding the program is effective to reduce debugging time, and that exchanging knowledge using shared file asynchronously is effective as well.

Scrolling the Text Windows by Looking

YAMATO Masatake, MONDEN Akito, TAKADA Yoshihiro, MATSUMOTO Ken-ichi, TORII Koji

Transactions of Information Processing Society of Japan 40 ( 2 ) 613 - 622 1999.2

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

This paper proposes a method and implementation for a system to automatically scroll a text window by tracking where a user is looking at. A user of the system can access a portion of the displayed document without using keyboard or mouse. Existing eye-tracking methods, which use eye-gaze as a substitute for pointing devices, require a user to "look at" menus and icons to manipulate a window display. In contrast, our proposed method uses eye movement within a window to control its display. A position of a user's gaze within a text window determines how to scroll the window, what portion of the text to display, and where to stop. Our user study demonstrates that the effectives of scrolling using this method is as good as one with convetional keyboard control as respects string search by scrolling. In particular, we have found that a controlling mechanism to determine the speed of scrolling in terms of the distance of the gaze point from the center of the window was both qualitatively and quantitatively superior to other control mechanisms in the string search by scrolling.

The purpose of our study is to clarify experts' debugging strategies through controlled experiment. In the experiment, we have used a periodic interview method to analyze the module that subjects think there is a bug in it during debugging. We have also analyzed the differences among subjects in time spent for reading each module. The result of experiment showed the differences between novices and experts in both the module that subjects think there is a bug in it, and the time spent for reading each module.

Technical report of IEICE. SS 96 ( 601 ) 1 - 8 1997.3

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In analyzing software development process, it is not easy to find or extract the subject's specific behavior. This paper proposes a retrieving system using behavior data (key stroke, gaze point on CRT, etc.) for video recordings of software development activities. This system shows graphs of process data, so that identifying characteristic behaviors and specify the time they occured are easy. In order to evaluate this system, we conducted an experiment to retrive subject's specific behavior such as "lost himself" from the behavior data. There were 8 scenes identified by having an interview with the subject. It resulted in 6 out of 8 scenes being automatically retrieved.

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

To clarify factors that affect efficiency of debugging, we need to investigate programers' intentions which continuously vary during. For the purpose, we have developed a system for observing programmers behavior by using an eye tracking device and audio and visual devices. By using the system, we have performed an experiment of observing bug identification processes. This paper presents results of the experiment,including the fact that collecting and analyzing multimodal data, such as motion of gazing point and record of verbal protocol, is effective in investigating programmers' intentions. It also includes several differences among observed processes which are likely to relate to the efficiency of bug identification.

An Experiment to Evaluate Methods for Program Scrambling

MONDEN Akito, TAKADA Yoshihiro, TORII Koji

IPSJ SIG Notes 1996 ( 32 ) 33 - 40 1996.3

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

It is important to write programs that are easy to analyze or understand so that the load on software maintenance and reuse can be lessened. 0n the other hand, when finished programs are released to many users there are cases where programs should not be analyzed easily, in order to protect the intellectual properties or to insure system security. In such cases, we believe that it is effective to write programs that are easy to analyze at first, and transform it so that it becomes difficult to analyze. Such an equivalent transformation is called "program scrambling." We present two methods for automatically scrambling programs that contain loops, and report on an experiment for validation of the methods. The result of the experiment shows that the methods are effective even for very small Programs.
