Improvement in Multi-User Communication Systems Using an Avatar's Facial Expression Features

Abstract: L'Xie investigated how an avatar\"s facial expression fiunction efl'ects useFs: motivation to engage in conversation and ability to understand a partner's einoLion during online ehat communication and attempted to improve the chat system based on the usabiliLy ratings of this function. In Experiment 1, 15 pairs of university students chatted in Engtish using both an emoticon-input facial expression system and a non-facial expression systom. The evaluation of the systems' usability indicated that the emoticon-input sysLem was nut superior to the non-facial expression system. The eTnoticon-input system was thus modified Lo an icon-input system to improvc its usability. In Experiment 2, 16 pairs of students chatted in Japenese using boLh Lhe ieon-input facial expression system and the non-facial expression s>Jstem and guessed t.heir partner's emutionul states during the chat. I'articipants tbund it easier to guess their pnrtner's emot[ons when using the lacial expression system. We discuss the outcomes and [imitations of' our experifnenLs for future research,

A proposal for metadata to express students' "presence" in digital photos : Use in the determination of equality in groups of photos

Abstract: In this research, we target students' photos for school use. When using students' photos in a class newspaper, teachers have to treat students equally. Usually in this case, the teacher counts the number of times a student appears in the photos. However, by only using this method it is difficultto feature students equally, since there are various kinds of photos, such as individual photos, group photos, etc. Considering this particularity of school use of photos, we propose the concept of \"presence,\" which expresses the impact of the face in a photo, by examining every subject in the photo, and measuring the students equally^using the; \"presence\" points of each subject. In this paper, we present a regression formula of \"presence\" using simple and objective items. Next, we present an experiment we conducted which measured perceptions of equality of student exposure in photos using the sum of \"presence\" points. The result of the experiment was the group of photos where \"presence\" points were within the predicted \"range of equality\" was judged to be fair.
