Requirements Capture: Using UML Use Cases

This is a presentation for our year one INFO1008 course of Computational Systems. It covers the need for requirements capture and the difficulty of building a specification based on user information. We present UML Use Cases and Use Case diagrams as a way of capturing requirements from the users point of view in a semi-structured way.

WAIS Seminar:Evaluating the Cognitive Side of Information Interaction

Abstract In this talk, I'll focus on the work we've been doing on evaluating the cognitive side of dealing with information resources and increasingly complex user interfaces. While we can build increasingly powerful user interfaces, they often come at the cost of simple design and ease of use. I'll describe two specific studies: 1) work on the ORCHID project focused on measuring mental workload during tasks using fNIRS (a blood-oxygen-based brain scanner), and 2) a evaluation metric for measuring how much people learn during tasks. Together these provide advances towards understanding the cognitive side of information interaction, in working towards building better tools for users.

WAIS Seminar:LinkedTV: Building the Future of Television

Abstract Broadcast video can be augmented with links to information related to the topics in the video and to other related entities. Viewers are sufficiently digitally literate that they can carry out their own searches during or after a broadcast. We investigate what types of information viewers would actually like to see while being engaged in watching a news broadcast. On the base of this we have designed user interfaces for passive and active uses of a second screen to accompany a news broadcast. A next step is to understand the specific types of information users would like to consult and investigate whether these can be automatically generated.
