Scanning Images

Sometimes you may need to scan in photographs, books or magazines. Scanning is the easy part but making sure your settings are right is the important part. Scan at 300dpi to the size you need to print A4 scanner but you need A3 print - no problem scan at 600dpi Always scan as a TIFF file format as this will give you a non compressed source to work from.

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.
