Designing for ultra-mobile interaction: experiences and a method

The research for this thesis has been conducted in various business units of Nokia during the years 2003–2010

Usability methodology has matured into a well-defined, industrially relevant field with its own findings, theories, and tools, with roots in applying information technology to user interfaces ranging from control rooms to computers, and more recently to mobile communications devices. The purpose is regularly to find out the users’ goals and to test whether a design fulfils the usability criteria. Properly applied, usability methods provide reliable and repeatable results, and are excellent tools in fine-tuning existing solutions.

What’s the problem? Studies on identifying usability problems in user tests

This is the kind of muttering researchers in a usability lab often hear when users are having trouble performing a given task with the product or prototype being tested./strong>

The activity the researcher is performing in this situation is called conducting a usability test: a test to find out what difficulties people run into when they are trying to use a (newly designed) product. During the usability test and in inter views or analyses afterwards, the researcher will try to figure out why the user experienced a given difficulty and what product characteristics contributed to that. Once the problem is understood, a designer can attempt to redesign the product’s characteristics so that the chance of future users running into the same difficulty is minimized.
