JOURNAL FREE ACCESSIn this paper, we discuss about “pleasant interaction with computational systems”. Correspondence differs between a user in front of a computer and a user in front of a human being. We argue that this “correspondence difference” needs to be addressed in order to design systems that keep the user's interest. To discuss pleasant interaction, we conducted some psychological experiments using a word tennis game. In this paper, we report the following. (a) Even though the information that a user receives is identical, the user's cognitive appraisal changes whether the user is in front of a computer or a human being. (b) When time passes, the corresponding difference of the user increases, at least in some cases. (c) Even if a program simulated a human being extensively, the change occurs.View full abstractDownload PDF (11224K) -

JOURNAL FREE ACCESSThe range of computer-supported work has been expanding, and will come to extend deeply into our everyday lives, beyond the present limited facets of our daily work.
In this paper, two opposite styles of Human-Computer Interaction (HCI), Amusement Park style and Japanese Garden style, are introduced to illustrate the concepts of the smooth temporal continuity throughout a series of daily tasks, and harmony between the real world (R) and the virtual world (V) of computer-supported work. In Amusement Park style, the virtual world is isolated from the real world. Humans are required to work within an enclosed virtual-world environment. Therefore, smooth temporal continuity with the previous and subsequent real-world tasks cannot be guaranteed. On the other hand, in Japanese Garden style, the virtual world and the real world are not isolated from each other, but rather harmonized. The aim in this style is to create a continuity, with smooth transition from one task to another.
On the basis of the above two concepts, we discuss aspects and styles of integrating of two heterogeneous worlds, V and R. These aspects and styles are deeply related to realizing an inspiring everyday life, in which our daily work is enhanced through the magical power of artifacts, while maintaining smooth temporal continuity throughout a sequence of everyday tasks.View full abstractDownload PDF (1195K) -

JOURNAL FREE ACCESSThe characteristics of the factor to improve the visual discriminability of depth perception by binocular parallax like pattern, contour lines and texture were investigated with using the stereoscopic microscope. And the stimulation (information) by texture and effect of optical illusion was investigated after obtaining improved and stable condition of the visual discriminability. A series of experiments was also separately done by skilled and non-skilled groups to investigate optical illusion and effects of practice. The results are as follows.
(1) It is confirmed that the amplitude of depth for the high visually discriminated pattern is about 46 seconds as the difference of the angle at binocular parallax. (2) It is seen that the identification of the contour lines will be significantly improved by the accuracy of its edge (depth corrugation) on manufacturing. (3) It can be found that the eye stimulation (information) due to texture only improve the visual amplitude of depth in case of the minute surface. The visual discriminability becomes worse gradually until texture stimuli become equal to depth perception in accordance with increase of stimulation. When it exceed more than depth of perception, the effect of optical illusion is improved quickly and it relates to get worsening of the visual discriminability. (4) There exists a clear difference between skilled and non-skilled in terms of the identification of depth perception. Non-skilled are apt to create optical illusion easily.View full abstractDownload PDF (1204K) -

JOURNAL FREE ACCESSIt was investigated what kinds of olfactory stimuli tended to recall past memories and evoke the affection of nostalgia (natsukashisa) to the healthy Japanese aged people. Eight typical odors were selected from the result of a questionnaire to 110 aged people. The odors were rose, perfume, gardenia, Indian ink, cigarette, milk, feces and orange. Each odor was artificially prepared, micro encapsulated and printed on a paper card (5.5×9cm). Breaking capsules and sniffing each card, 119 aged people rated the perceived intensity, pleasantness, nostalgia and identification, and described remembrance called by each odor. The results were the following; 1) The odor of orange or perfume was correctly named and tended to arouse the affection of nostalgia more effectively than other odors, 2) The odors of orange, perfume, gardenia or milk was rated as more pleasant than the others, 3) The odor of orange or perfume was relatively effective to recall memories. These results suggested that the odor of orange or perfume was effective for the well-being of the aged Japanese people.View full abstractDownload PDF (2376K) -
