Question 32/I - Human factors issues of new and updated voice and non-voice telecommunications services (new Question) Considering (a) that there is continual design and development of new telecommunications services; (b) that it is the intention of this Question both to encourage the development of innovative technology and to avoid constraining one design of new equipment; (c) that existing telecommunication services are subject to updating and enhancement; (d) that all such services may be either voice or non-voice (e.g. picture, data or text) or a combination thereof; (e) that some new services will arise from the design and development of new telecommunications equipment (video-telephones, facsimile, etc.); (f) that customers will be required to operate such new equipment in order to access or utilize new or updated services; (g) that in order to minimize customer difficulties and maximize customer satisfaction, due consideration should be made to human factors aspects of the design, development and implementation of new or updated services, the following questions should be answered: 1. What new or updated telecommunications services and procedures can be identified requiring human factors studies? (Note 1) 2. What are the human factors requirements of such new or updated telecommunications services and what Recommendations are needed? 3. What are the human factors requirements of any new user interfaces that can be identified and studied in order to ensure that they can be made easy to use and what Recommendations are needed? 4. What measures can be taken to harmonize CCITT studies with forthcoming standards from ISO/TC 159 (Ergonomics) and with the IEC? Note 1 - Close liaison with other Working Parties and Study Groups should be maintained in order to identify human factors issues in new or updated telecommunications services. Note 2 - "User interface" is the human interface to various telecommunications components, including equipment, instructions, services and systems.
