Tutorial #11: Designing Highly Usable Wireless Services For Next Generation Devices and NetworksMonday, July 8th, 6:00 PM- 9:30 PMKeywordsSystem, Product, or Project Focus: Emerging interfacesTopic Category:Enhancing general usability skillsTopic Focus:Heuristic and guidelines, interaction design, user interface design, user-centered designAudience:Beginner, IntermediateAbstractIn this tutorial participants will learn how to develop successful wireless services for users who are the on the go. Participants will be provided with an overview of the critical user experience issues that need to be addressed when developing these services for the next generation of devices and networks.Target audienceThe tutorial will cover content central to usability issues when designing services for small display device. It will also cover a wide range of MMI-related topics such as usability assessment, user experience, killer application issues and interaction design. It is intended for people with some experience in either interface design or usability work. But it is also perfectly suitable for beginners since its content is not purely technical. Note that the tutorial is not designed for people willing to gain technical knowledge either on WML script or on WAP gateways. Such a tutorial might appeal to a broad audience, such as interface designers, application developers, service providers, usability specialist and HCI researchers.DurationThe tutorial is designed as a half-day session, i.e. a 3 hours long (not including breaks).Learning objectivesBy attending this tutorial, participants will:
Material that will be covered in the tutorialThe tutorial is completely new for UPA 2002 since it covers next generation of devices and networks (2.5G). We do think it might be of interest to the UPA audience. As a mater of fact, wireless services are becoming more common but not all of them gain wide acceptance. Some fail because users, who have little patience for learning how to operate them, find them too difficult to use. Due to inherent design limitations, including small display screens and limited data input from multifunctional keypads, service designers have to learn new ways to present information and interact with the user. This tutorial is based on latest research and development of mobile services. Its content has been developed and refined by the instructors over a period of several years while they were employed in the telecom industry. Details of each tutorial component are described below:Today's wireless devices: 'Space suit needed'
Next generation networks
Mobile users and the mobile context
Next generation of mobile devices (evolutions and limitations)
Killer experience: The right service to right user in the right location with timely information
Basic principles of highly usable interfaces for wireless services
Group Exercises: Usability inspection of a wireless service
Tutorial conductionThe tutorial is a combination of lectures segments, pen-paper exercises and group discussion. Either one of the instructors or both of they will present each component.LecturesThe tutorial is a set of lectures segments where the instructors will cover topics described above. Practical examples of wireless interfaces will be shown. Various situations and possibilities will be considered.Exercise session and discussionDuring the exercise session, participants will perform the same set of tasks by team. They will start with a brief usability inspection of a WAP application. They will judge whether the different interaction elements follow established usability principles. A debriefing group session will be conducted where different usability issues will be pinpointed and possible solutions discussed. The exercise material will be a paper-based demo of a WAP site, which will let the user search "online" for new and used toys at dealers throughout the US. Concurrently few WAP-enabled phones will be available for testing the service.ScheduleThe schedule below assumes the tutorial will be held during the morning session. If it is assigned to an afternoon session, the times will be modified appropriately.Tutorial notesDescriptionThe tutorial notes will be prepared as a student manuscript (approx. 45 pages). They will include copies of the PowerPoint slides; ample white space will be provided for comments and notes. In addition, the notes will contain a bibliography of the source for additional reading on interaction design and usability issues. Concurrently exercise material - that is a set of service screen-shots printed on paper (approx. 20 pages), including exercise instructions- will be given to the audience.Samples of materialsThe following are samples of material that will be included in the tutorial notes. These samples are extracted from the "Mobile users and the mobile context" section.

He is mainly involved with mobile device research. He has extensive experience in designing and evaluating user interfaces. Some of them have been shown at international fairs such as COMDEX, CeBIT and Communc'Asia. He is also active at conferences with lectures and written contributions pertaining to wireless devices (e.g. PC-HCI'2001, IHM-HCI'2001, HFT'2001, OzCHI'2000, INTERACT'99). Until 1998, he worked as a Human Factor Researcher at the Ericsson Medialab, exploring and prototyping usable interactive end-users applications. Didier also acquired a wide variety of skills as an ergonomist at the French Aerospace Agency named Aerospatiale from 1990. He cooperated with French astronauts on the definition of interior arrangement of Hermes, the European Space Shuttle. He also collaborated with the French Civil Aviation Authorities on the GUI of the future French ATC (Air Traffic Control) system called PHIDIAS. His role was to write recommendations that define the new colour standards, the information coding and the alphanumeric fonts for the ATC workstations. Mikael Eriksson has been working as an Interaction Designer for the Usability and Interaction Lab at Ericsson Research since October 2000. He is mainly involved on developing and prototyping interaction concepts. Before joining Ericsson Research, he worked for Ericsson GSM on the Net and developed several CTI (Computer Telephony Integration) products. Mikael has also worked as a design consultant running several web-based projects. Furthermore, he has a pedagogical background and has been teaching computer-based design at the University College of Arts, Crafts and Design in Stockholm, Sweden. Bibliography of presenters 1.
