With the increase of video conferencing users and the development of technology, the situations where video conferencing is used and the layout of video conferencing interfaces are diversifying. Social anxiety affects video conferencing communication and is closely related to the self-view function, which is characteristic of video conferencing. The self-view function is part of the video conferencing interface that provides a small preview of one's own camera feed. Self-view is known to degrade work performance and cause fatigue; however, it is set as the default function on video conferencing software in a way that users generally prefer. This study used an online survey to study the effect of task orientation, preferred self-view size, and social anxiety on video feedback preference. Participants responded to questions assessing work orientation, social anxiety level, preferred self-view size, and self-view preference. The results showed that preferred self-view size mediates task orientation and video feedback preference. There was no significant difference in the mediating effect of the preferred self-view size according to the degree of social anxiety. These results offer insights into the interactions between users and video conferencing software and provide information that can be useful for designing video conferencing interfaces.

Multimedia presentations are a class of documents that are used for lectures, tour guides, business presentations, and in many other applications. These presentations comprise multimedia objects with a temporal structure that specifies when objects are to be delivered, for what duration, and what the temporal relationships among objects are. In this paper, we propose temporal extensions to XHTML that allow seamless integration of synchronized multimedia into web documents. The extensions are based on three concepts：(i) XHTML＋TIME (in short, Xtime) links for temporal composition, (ii) common time bases for close synchronization between media objects, and (iii) dynamic layout for specifying regions of a screen for presentation. Also, we will show a flexible execution architecture to support these concepts in a multimedia presentation.
