Close but Not Too Close: Distance and Relevance in Designing Games for Reflection
Sign Up to like & getrecommendations! Published in 2022 at "Proceedings of the ACM on Human-Computer Interaction"
DOI: 10.1145/3549487
Abstract: Reflection is an important precursor to attitude and behavior change, but existing advice on designing for reflection in games is mixed and requires further empirical investigation. We report on the design and evaluation (n=32) of… read more here.

DOI: 10.2528/pierb17012701
Abstract: In this paper the results of the estimated electric field associated with tortuous lightning paths at close distance (50 m to 500 m) are shown. Such results are compared with experimental data available in the… read more here.
