Sammanfattning: The unit of Cognitive Developmental Neuroscience at Karolinska Institutet have developed a method for measuring cognitive performance with handheld devices, which resulted in a mobile application for the iPod Touch. The application was previously used in a clinical trial with individuals suffering from chronic stress disorder, but had to be further developed. The application, which consisted of cognitive tests and questionnaires, required improvements that could be divided into three parts: (1) a long-term memory test, (2) presentation of results and progress, and (3) an interface comprehensible to individuals with cognitive impairments. The work of this thesis was to process a requirement specification and research the areas of long-term memory testing, data presentation, and usability. The findings were used to come up with design suggestions for the application, and eventually implement them. The application was developed using C# and the MonoTouch SDK, to make it run on the iPod Touch. Distributed to physical devices, the application was finally evaluated to make sure the requirements were satisfied. Presentation and evaluation of the application were done with people from Karolinska Institutet. The results from the long-term memory test suggested it was sometimes too easy remembering items, and in a few cases even a ceiling effect appeared. However, the future target group, which was individuals with cognitive impairments, would likely perform less well on the test, and the test was therefore kept after discussion with the unit of Cognitive Developmental Neuroscience. The presentation of results as well as the navigation system were received with positive feedback.
