Head-locked, world-locked, or conformal diminished-reality? An examination of different AR solutions for pedestrian safety in occluded scenarios

Many collisions between pedestrians and cars are caused by poor visibility, such as occlusion by a parked vehicle. Augmented reality (AR) could help to prevent this problem, but it is unknown to what extent the augmented information needs to be embedded into the world. In this virtual reality experiment with a head-mounted display (HMD), 28...

Share Your Reality: The effects of haptic feedback on virtual avatar co-embodiment

The advent of Virtual Reality (VR) technologies has begun a shift in communication between people and their interaction with 3D virtual environments. VR has great potential to provide high immersion to users, allowing designers to create vivid and impossible interactions. However, while software and technology play a crucial role in creating a...

Effects of Virtual Reality characteristics on collaboration between learners: Do visualizations of activities have an effect on an individual’s situational awareness when collaborating with others inside Virtual Reality?

Background<br/>This research explores the role of visualization tools in enhancing collaborative learning in virtual reality environments.<br/>Methodology<br/>An experiment was conducted, involving two groups of participants, each tasked with collaboratively solving a complex maze in a virtual reality environment. Both groups experienced two...

Using virtual reality to study pedestrian exit choice behaviour during evacuations

Exit choice is vital to pedestrians’ survival during evacuations. This paper presents the results of a VR experiment and a field experiment to study pedestrian exit choice behaviour during evacuations. Primarily, we compared pedestrian exit choice behaviour with a VR experiment and a field experiment to determine the ecological validity of a...

Overcome: Reducing ICU patients' anxiety through medical alarms feedback provision

In the Intensive Care Units (ICU) patients are exposed to many, continuous and highly stressors, such as medical alarms, which contribute to the development of psychological issues, such as delirium, anxiety disorders and post-traumatic stress disorders (PTSD). These psychological issues have a negative influence on the patients’ healing process...

Safety Margin Development for a Space-Time Reservation Traffic Control System: A Research considering the Hybrid Traffic Period

With the arrival of Connected and Automated Vehicles (CAVs) concepts for traffic control systems emerge that let CAVs weave over the crossing area of an intersection. However, in the current literature, the safety of these vehicles is generally an assumption rather than a certainty. Moreover, the time period where CAVs and Human-Driven Vehicles ...

Pedestrian exit choice behavior during an evacuation - a comparison study between field and VR experiment

Understanding pedestrian exit choice behavior during emergency situations is important for improving evacuation efficiency. Virtual Reality is a promising technique that can be used to study pedestrian evacuation behavior. However, studies comparing evacuation behavior in real and virtual environments are still scarce. This paper explores...
