In an interdisciplinary cooperation with colleagues from the chair of Computer Engineering and the chair of Computer Graphics and Visualization at the TU Chemnitz, we developed a computer-based memory training. It is operated via spoken dialogues, teaches the well-known “method of loci” (also known as “memory palace technique”) and features a virtual agent as a trainer. It served as a use-case for testing effects of system-induced delays on cognitive performance, which have been explored in two Wizard-of-Oz studies with students and elderly participants.
Results indicate a trade-off between individual preferences and cognitive effects when obtaining optimal system response times. Potential next steps involve the test of alternative training scenarios, the technical implementation, and comprehensive user tests with the working system.
