Abstract
Virtual Reality (VR) has emerged as a powerful technology for creating immersive and engaging simulations that enable users to interact with computer-generated environments in a natural and intuitive way. However, the design and implementation of effective interaction methods in VR remain challenging. The lack of proper haptic feedback, and the need to rely on input devices such as controllers or gestures, for example, can result in awkward or unnatural interactions, reducing the perceived level of realism and the immersion related to the VR experience. At the same time, the employment of poorly designed interaction paradigms may impair usability, reduce the the sense of presence, and even cause unpleasant effects related to the so called cybersickness. This doctoral thesis, which covers a subset of the the research work performed in the three-year Ph.D. period, aims to address these challenges by investigating the role of interaction in VR simulations. The investigated topics range from the study of locomotion interfaces in VR, to the use of haptic interfaces for simulating passive and haptic tools applied to real life training use cases and the exploration of further forms of Human-Computer Interaction (HCI) and Human-Human Interaction (HHI) through voice and body gestures, also in the context of multi-user shared simulations. Results obtained in the considered case studies cover a wide number of relevant aspects, such as realism, usability, and engagement of VR simulations, among others, ultimately leading to a validation of proposed approaches and methodologies.In this way, the thesis contributes to the understanding of how to design and evaluate interaction paradigms in VR simulations in order to enhance aspects related to User eXperience (UX), with the goal of letting users successfully achieve the intended simulation objectives.
