scope:

The present document is based on EG 202 534 [3] and a web-based guideline Access and Tutorial System (http://portal.etsi.org/stfs/STF_HomePages/STF284/STF284.asp). The main content of EG 202 534 [3] are guidelines for the real-time person-to-person communication services that provide text communication, audio communication, avatar communication, data communication, video communication and multimedia communication. Service topics include audio-video asynchrony, video resolution, video delay and packet loss for fixed and mobile networks. User topics include communication tasks (e.g. negotiation, joint problem solving and persuasion), usage outcomes (e.g. task efficiency, task effectiveness and user satisfaction) and special user groups (e.g. persons who are deaf, blind and elderly).

About 650 intended guideline users have been involved in the development work of EG 202 534 [3] and the associated web-based system. The present document describes the requirements for guidelines and the tutorial system that were identified. It considers three main areas of future work based on experiences from the project:

• Enhancement of the existing EG 202 534 [3] (e.g. through collection of test data on important topics).

• Enhancement of the web-based tutorial system.

• New service areas.
