Context-Based Interface Prototyping and Evaluation for (Shared) Autonomous Vehicles Using a Lightweight Immersive Video-Based Simulator

Making emergent technologies more tangible - Effects of presentation form on user perceptions in the context of automated mobility

“…Another commonly used presentation form in user research on emergent technologies is simulations. Most simulations display computer-generated virtual environ ments (Flohr et al 2020), which can easily be manipulated by researchers to alternate individual variables while keeping everything else constant (Pan and Hamilton 2018), thus maximising experimental control. In the con text of research on automated mobility offerings, various simulation platforms are being used, including CAVE-like setups, driving simulators, and VR headsets (so-called head-mounted displays, HMD) (Hoggenmueller et al 2021), while research on human-robot interactions typi cally resorted to the use of HMDs (e.g.…”

“…Compared to computer-generated environments, realworld videos can ensure higher visual realism and famil iarity (Gerber et al 2019). Notably, real-world videos can represent not only the subject of investigation but also a rich context at a higher level of realism (Flohr et al 2020). This is particularly helpful in scenarios where context and environment are highly complex and dynamic, such as driving scenarios.…”

“…Additionally, real-world videos can represent not only the subject of investigation, e.g. the automated vehicle, but also a more detailed context at a higher level of realism (Flohr et al 2020). This may be beneficial in cases where not only a specific object, like a product or prototype, is to be evaluated, but rather an experience, which requires more contextual information.…”

“…Immersive visual projections and sound are also increasingly being used to prototype and evaluate "context-based interfaces" (Flohr et al, 2020;Hoggenmueller et al, 2021) for autonomous vehicles. Flohr et al (2020) demonstrate the value of room-scale immersive video and sound in providing a sense of presence and realism.…”

“…Immersive visual projections and sound are also increasingly being used to prototype and evaluate "context-based interfaces" (Flohr et al, 2020;Hoggenmueller et al, 2021) for autonomous vehicles. Flohr et al (2020) demonstrate the value of room-scale immersive video and sound in providing a sense of presence and realism. Building on this work Hoggenmueller et al (2021) compared user interactions with prototypes using 360-degree real world video or computer-generated images on virtual reality (VR) headmounted displays or a PC monitor.…”
