Evaluation of User Interfaces for Three-Dimensional Locomotion in Virtual Reality
SUI '22: Proceedings of the 2022 ACM Symposium on Spatial User InteractionArticle No.: 8, Pages 1–9https://doi.org/10.1145/3565970.3567693Locomotion is an essential factor for interaction in virtual environments. Virtual reality allows users to move freely from the constraints of gravity or the environment, which is impossible in the real world. These experiences, in which users can move ...

Estimation of wakefulness in video-based lectures based on multimodal data fusion
UbiComp/ISWC '20 Adjunct: Adjunct Proceedings of the 2020 ACM International Joint Conference on Pervasive and Ubiquitous Computing and Proceedings of the 2020 ACM International Symposium on Wearable ComputersPages 50–53https://doi.org/10.1145/3410530.3414386In distance learning contexts, drowsiness is a major factor which disturbs learning. However, it is not easy for instructors to monitor students' wakefulness. In order to improve learning efficacy, accurate estimation of wakefulness is needed. In this ...
