Temporal aspects of tasks in the user action notation

Abstract: The need for communication among a multiplicity of cooperating roles in user interface development translates into the need for a common set of interface design representation techniques. The important difference between design of the interaction part of the interface and design of the interface software calls for representation techniques with a behavioral view - a view that focuses on user interaction rather than on the software. The User Action Notation (UAN) is a user- and task-oriented notation that describes physical (and other) behavior of the user and interface as they perform a task together. The primary abstraction of the UAN is a user task. The work reported here addresses the need to identify temporal relationships within user task descriptions and to express explicitly and precisely how designers view temporal relationships among those tasks. Drawing on simple temporal concepts such as events in time and preceding and overlapping of time intervals, we identify basic temporal relationships among tasks: sequence, waiting, repeated disjunction, order independence, interruptibility, one-way interleavability, mutual interleavability, and concurrency. The UAN temporal relations, through the notion of modal logic, offer an explicit and precise representation of the specific kinds of temporal behavior that can occur in asynchronous user interaction without the need to detail all cases that might result.

Study planner system and method

Abstract: A method and system for setting up and using a personal learning schedule and path through an instructional product. Using a wizard-style interface, a study plan is established for a user based on a session frequency, along with the date the user wishes to finish the instructional product or the amount of time that the user has available each session. Once the user has set up a study plan, each time that user logs in, the user is taken to that day's list of assigned activities on a personalized home page. From there, the user is able to check activity status for past and future lessons, and quickly navigate to a lesson. Users can set up their own personalized learning schedule based on their own study objectives. The method and system further allow the user to determine a skill level required to complete the activities, and further monitors the user's progress in successfully completing those activities.

Adaptable and adaptive information provision for all users, including disabled and elderly people

Abstract: Due to the rapidly increasing popularity of the World-Wide Web, hypermedia is going to be the leading online information medium for some years to come and will most likely become the standard gateway for citizens to the “information highway” Today, visitors of web sites are generally heterogeneous and have different needs, and this is likely to increase in the future The aim of the AVANTI project is to cater hypermedia information to these individual needs by adapting the content and the presentation of web pages to each individual user The special needs of elderly and disabled users are also partly considered A model of the characteristics of user groups, individual users and usage environments, and a domain model are exploited in the adaptation process One aim of this research is to verify that adaptation and user modeling techniques that were hitherto mostly used for catering interactive software systems to able-bodied users also prove useful for adaptation to users with special needs An

User-Centred Design of Flexible Hypermedia for a Mobile Guide: Reflections on the HyperAudio Experience

Abstract: A user-centred design approach involves end-users from the very beginning. Considering users at the early stages compels designers to think in terms of utility and usability and helps develop a system based on what is actually needed. This paper discusses the case of HyperAudio, a context-sensitive adaptive and mobile museum guide developed in the late 1990s. User requirements were collected via a survey to understand visitors' profiles and visit styles in natural science museums. The knowledge acquired supported the specification of system requirements, helping define the user model, data structure and adaptive behaviour of the system. User requirements guided the design decisions on what could be implemented by using simple adaptable triggers, and what instead needed more sophisticated adaptive techniques. This is a fundamental choice when all the computation must be done on a PDA. Graphical and interactive environments for developing and testing complex adaptive systems are discussed as a further step in an iterative design process that considers the user interaction to be the central point. This paper discusses how such an environment allows designers and developers to experiment with different system behaviours and to widely test it under realistic conditions by simulating the actual context evolving over time. The understanding gained in HyperAudio is then considered from the perspective of later developments: our findings still appers to be valid despite the time that had passed.
