Hiding Assistive Robots During Training in Immersive VR Does Not Affect Users’ Motivation, Presence, Embodiment, Performance, Nor Visual Attention

Combining immersive virtual reality (VR) using head-mounted displays (HMDs) with assisting robotic devices might be a promising procedure to enhance neurorehabilitation. However, it is still an open question how immersive virtual environments (VE) should be designed when interacting with rehabilitation robots. In conventional training, the...

Metaverse beyond the hype: Multidisciplinary perspectives on emerging challenges, opportunities, and agenda for research, practice and policy

The metaverse has the potential to extend the physical world using augmented and virtual reality technologies allowing users to seamlessly interact within real and simulated environments using avatars and holograms. Virtual environments and immersive games (such as, Second Life, Fortnite, Roblox and VRChat) have been described as antecedents of...

Conversational Crowdsourcing

Crowdsourcing has become a standard approach for the collection of the human input required by scientists and practitioners alike to execute their experiments, or to train, control, and verify the behavior of their intelligent systems. Despite years of successful research and industrial application, how to improve the engagement and satisfaction...

Designing and Evaluating Avatar Biosignal Visualization Techniques in Social Virtual Reality

Social VR is the application of virtual reality that supports remote social interaction in virtual spaces. Users communicate and interact with others in the social VR environment through avatars, which are virtual anthropomorphic characters that aim to represent humans in virtual worlds. In addition, the development of the HMD and commercially...

Using Worker Avatars to Improve Microtask Crowdsourcing

The future of crowd work has been identified to depend on worker satisfaction, but we lack a thorough understanding of how worker satisfaction can be increased in microtask crowdsourcing. Prior work has shown that one solution is to build tasks that are engaging. To facilitate engagement, two methods that have received attention in recent HCI...

Air-Centered Business Travel: Ecomobility 2035

How does business traveling look like in the future? This master project examines the todays travel landscape and uncovers issues business travelers are experiencing during their trips. With the stakeholder Embraer - an aircraft manufacturer from Brazil - the context of this project is very intentionally set to a door-to-door journey with...

Effects of Using Avatars in a Game-Based Learning Environment

Peer reviewing is an approach often used in digital (higher) education as it represents a possibility to provide feedback to large student groups. However, especially in digital learning contexts, students feel being disconnected from the anonymous group of learners, leading to low-quality feedback. When feedback is open, and counterparts are...

Dynamic Stall Modeling for Wind Turbines

Modern wind turbines frequently operate at off-design conditions during their life cycle. They undergo dynamic loads characterized by unsteady aerodynamics. Predicting these unsteady aerodynamic loads has been very difficult due to the non-linear nature of unsteady aerodynamics. Especially when operating near the stall region, these turbine are...

Design and Development of a Physical and a Virtual Embodied Conversational Agent for Social Support of Older Adults

Populations in developed societies show an increasingly higher life expectancy across the globe. To support older adults to live longer and healthier lives in the familiar surroundings of their homes, technological developments, such as robots and avatars, have a great potential. To investigate long-term interactions between older adults and a ...
