A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

2017

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…

How to get things done in social virtual reality : A study of team cohesion in social virtual reality–enabled teams

2022

Social virtual reality (SVR) enables teams to operate in a virtual environment that simulates and enhances real-world interactions. However, there is an absence of empirical analysis of how SVR can affect the performance of virtual teams. This paper documents how SVR affects the formation of team cohesion (i.e., task cohesion and social cohesion), which is a critical success factor for team performance. To address this gap in the research, we conducted a qualitative study by interviewing 20 members from virtual teams assigned to perform a challenging collaborative task in SVR. As a contribution, our study identifies five primary affordances and 11 sub-affordances for team cohesion in SVR. W…

Video projection mapping e arti performative. Una nuova macchina scenotecnica della visione per generare nuovi spazi aumentati

L’oggetto principale della dissertazione è il video projection mapping, un’applicazione di realtà aumentata che utilizza le tecniche di videoproiezione digitale non su tradizionali schermi di proiezione ma sulla realtà stessa, sugli oggetti fisici, ai quali si adatta e si lega in maniera inestricabile, ibridando il livello fisico-reale e il livello digitale. Al contrario di come spesso è stato considerato, il video projection mapping non è solo un gadget tecnologico dei nostri tempi; quando si ibrida con altri media, come le arti performative, diviene linguaggio metaforico, oltrepassando il suo livello tecnologico per produrre significati, per mediare idee. Considerando il suo uso nello spe…
