There have been many studies in the field of kansei, recently. However, from the methodological viewpoint, there have also been confused.
The purpose in this paper is to point out some problems in measurement, to formulate the schema and propose the way of evaluation on the kansei studies.
Two types of evaluating are considered to specify the problems. One is to evaluate designs, which is not thought its importance; the other is to evaluate results. The former is the basis of validity and reliability of the measurement.
Recent studies describe the kansei concepts by both subjects and common scales. And in its design, to describe subjects cannot describe subjects in itself.
In the sensory inspection, there are well-known two types of measurement. But the problem subject’s ability is left in the kansei studies.

Video display of lager size such as 12” have been more and more used for presentation in a group works they can conveniently display images obtained TV camera, disk storage and computer. Larger screen displays may also become more attractive for virtual reality system because of the irresistible realistic images due to the screen size. In these cases, a pointing device such as a mouse is frequently used for the communication between human and system. In this study, a comparison between video displays of different sizes is done if there are differences in eye movements although the angle of view remains the same. The use of pointing device is evaluated when mouse tracking on video display is requested.

Traditional research on computer and human interactions had focused on the physical and/or mental effects on humankind. As the computer widely spread in office environment and used to communicate between one and other daily, we must mention about its organizational effects. The electronic communication methods not only make easily to communicate each other, but also make change the communication style, contents, and social organization. It should be treated as new ergonomic problems of highly computerized age. We discuss these problems in office environment and recommend using the multimedia technologies as a part of its solutions.

Recently the image Delphi method has been used in the design and marketing fields. However, this method is defective in the arbitrariness in the map meaning, the interpretation of coordinate axes and the naming band the naming bases obtained by this method. The objectives of this monograph are the interchange analysis as the method of the character-behavior analysis in the clinical psychological field, the structural analysis of sub consciousness of human being etc. as well as the investigation as to the question if the coordinates of egogram used in the interchange analysis are useful for the meaning of an image map, the interpretation of coordinate exes, the naming, etc.
Firstly, in order to investigate into the fundamental structure of the image map, the propriety or egogram utilization was groped. Successively the words corresponding to respective quadrants of this fundamental structure were abstracted so that the image pictures of various goods previously collected may be made up according to the abstracted words. Thus, the close correlations with the Image Egogram can be detected in the light of the results of egogram given by the tested persons. Resultantly, it was elucidated that the egogram can be used for the image Delphi method. By the way, this image egogram as the title theme is a coinage word of the image map made up by the image selecting method on the premise of the egogram.

Binocular stereoscopic displays have been widely used as effective demonstration in the virtual reality. It is suspected that the reciprocal relation in the visual functions is collapsed as compared with normal viewing when looking at the binocular stereo-scopic images. The eye movement during images load were measured using a nelectro0oculogram (EOG) to investigate the effects of the stereo parallax on visual functions facility. The effect of the large-parallax stereoscopic images was that EOG disintegration was high, indicating significant inhibition of cooperative movement of the eyes.
