Interaction style and specification of the occasional user of digital interfaces: perspectives from interdisciplinary assessment of virtual agent spatial guidance
… target items inside a Ul. Dynamically animated virtual agent (VA) gaze and head cues were found to guide eye gaze and button presses faster than 1-image and 2- image agent cues. When these cues were animated using the principles of animation, they introduced a substantial increase in the …

Evaluation of the implementation of a psychological behaviour change model to promote energy saving behaviour. Implementation of a mobile app with the virtual robotic head Floka
… the desired effects on the users' behaviour. The virtual agent Floka was integrated into the app as an interaction partner that is supposed to contribute to the app's persuasive effect through its socio-emotional expressiveness. In addition, various gamification elements support the motivation for …
