The Method of Loci (MOL) is a mnemonic strategy to memorize declarative knowledge. In the late 90s researchers started to experimentally analyze the MOL by providing their participants a virtual world. This digital environment was meant to serve the users as a template for their personal memory palace. Past studies differed in central aspects of their experimental design. One difference is that earlier studies integrated the learning content in multiple and different ways. The design of the learning content is an essential aspect and should make a difference based on cognitive theories. This study analyzes if participants perform better with virtually presented learning content or if the MOL works better when users have to imagine the content. Results encourage future concepts of the virtual MOL to implement the learning content in the environment.

The Method of Loci (also memory palace) is the most powerful mnemonic strategy and was widely analyzed over the last twenty years. Especially, the approach to combine this ancient learning method with modern technology got more and more into the focus of an interdisciplinary research community. Researchers presented their students virtual environments via computer screen or head-mounted displays and instructed them to use these virtual worlds as a template for a memory palace. However, most studies did not investigate the users' attitude to actually use such a tool in everyday situations. This study addresses this research gap by an experiment and a correlation and regression analysis. Results show significant correlations between the learning success and important factors of the users intention to use a virtual memory palace.

This paper presents a systematic literature review of mission management user interfaces for UAVs, with the aim of providing insight into the current state of research in this area. A total of 25 relevant publications were identified, and an overview of their content is provided. The review also discusses multimodal interaction approaches presented in these papers and highlights an emerging trend towards a more usercentric design process for UAV user interfaces. The findings of this review contribute to the understanding of existing research and offer guidance for future developments in the design of mission management user interfaces for UAVs.
