2. Agenda Introduction Current Areas of Research – Multimedia Information Systems – User Interfaces – Group and Organization Interfaces – Hypertext/Hypermedia – Sound and Music Computing – Miscellaneous Conclusions 2

3. Introduction The advantages of ubiquitous mobile computing are only accessible if systems are easy to use. The current expansion in smart phone usage began with the iPhone and its radically new user interface. Mobile computing systems place a premium on good human factors design due to the reduced size of displays. 3

4. Definitions Human Factors is a discipline of study that deals with human-machine interface. Human Factors deals with the psychological, social, physical, biological and safety characteristics of a user and the system the user is in. Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them. 4
