Human-CenteredSoftwareEngineering: BridgingHCI,UsabilityandSoftwareEngineering From its beginning in the 1980’s, the ?eld of human-computer interaction (HCI) has beende?nedasamultidisciplinaryarena. BythisImeanthattherehas beenanexplicit recognition that distinct skills and perspectives are required to make the whole effort of designing usable computer systems work well. Thus people with backgrounds in Computer Science (CS) and Software Engineering (SE) joined with people with ba- grounds in various behavioral science disciplines (e. g. , cognitive and social psych- ogy, anthropology)inaneffortwhereallperspectiveswereseenasessentialtocreating usable systems. But while the ?eld of HCI brings individuals with many background disciplines together to discuss a common goal - the development of useful, usable, satisfying systems - the form of the collaboration remains unclear. Are we striving to coordinate the varied activities in system development, or are we seeking a richer collaborative framework? In coordination, Usability and SE skills can remain quite distinct and while the activities of each group might be critical to the success of a project, we need only insure that critical results are provided at appropriate points in the development cycle. Communication by one group to the other during an activity might be seen as only minimally necessary. In collaboration, there is a sense that each group can learn something about its own methods and processes through a close pa- nership with the other. Communication during the process of gathering information from target users of a system by usability professionals would not be seen as so- thing that gets in the way of the essential work of software engineering professionals.

Multiple User Interfaces allow people using mobile phones, lap tops, desk tops, palm tops or PDAs to access and read information from their central server or the internet in a coherent and consistent way and to communicate effectively with other users who may be using different devices. MUIs provide multiple views of the information according to the device used and co-ordinate communication between the users. Multiple User Interfaces: Engineering and Applications Frameworks is the first work to describe user interface design for mobile and hand-held devices such as mobile phones. Given the proliferation of books on web site design in the late '90s, this promises to be the forerunner in a new wave of books dealing with the issues specific to small screens, limited memory and wireless transmission. It also deals with problems relating to multi-user functionality and sharing the same application over various platforms. Offers a comprehensive account of state-of-the-art research Combines human and technical aspects including social interaction, workflow, HCI, & system architectures. Provides practical toolkits, guidelines and experience reports Includes contributions from leading experts at all the key institutions – Virginia Tech, Concordia University, Lancaster University, Ericsson & Intel With such a unique and cutting-edge approach researchers and developers working on user interface design in companies manufacturing handsets and other portable devices, university HCI groups and companies providing web-based information services for delivery to hand-held devices will find this indispensable.
