Tutorial: How to create a Hi-Res screenshot

Most of the time when you have to present screenshots for printing in a book or journal the standard resolution will not match the requirements supplied by the printer. The normal screen resolution is 72 or 96 DPI while allmost any professional printing press will require at least 300 DPI. Just resizing the images will make them fuzzy and blurry.

This tutorial explains how to create a sharp and hi-resolution screenshot on the CELSTEC MediaLab video-editing computer (room Chi 1.35) using SnagIt 8 and an old version of Photoshop.

Heuristic Evaluation

Yesterday we evaluated the interface design of some of the tools that UHI provides for their students through a heuristic evaluation. In both individual and group sessions we gathered a lot of information about possible usability problems within these tools.

Heuristic evaluation (Nielsen and Molich, 1990; Nielsen 1994) is a usability engineering method for finding the usability problems in a user interface design so that they can be attended to as part of an iterative design process. Heuristic evaluation involves having a small set of evaluators examine the interface and judge its compliance with recognized usability principles (the "heuristics").

More info about this method can be found on: http://www.useit.com/papers/heuristic/
