In order to develop a memory visualisation tool for older users that provides cognitive assistance, our first goal is to design, implement and test an appropriate memory visualisation tool. Two user studies were conducted in order to allow for iterative system development and involvement of participants with different ages.
Both experiments aim to answer three general research questions:
RQ1. How usable do participants find the memory visualisation tool?
RQ2. How useful do participants find the development and use of such a tool?
RQ3. What type of modifications to the visualisation tool do participants suggest?
