HydroHaptics: High-Fidelity Force-Feedback on Soft Deformable Interfaces using Hydrostatic Transmission

Soft deformable interfaces offer unique interaction potential through input flexibility and diverse forms. However, force feedback on these devices remains limited, with pneumatic approaches lacking responsiveness and precision, while microhydraulic solutions are constrained to small form factors with limited input.…

RetroSketch: A Retrospective Method for Measuring Emotions and Presence in Virtual Reality

Virtual Reality (VR) designers and researchers often need to measure emotions and presence as they evolve over time. The experience sampling method (ESM) is a common way to achieve this, however, ESM disrupts the experience and lacks granularity. We propose RetroSketch, a new method for measuring subjective emotions a…

Sweating the Details: Emotion Recognition and the Influence of Physical Exertion in Virtual Reality Exergaming

There is great potential for adapting Virtual Reality (VR) exergames based on a user's affective state. However, physical activity and VR interfere with physiological sensors, making affect recognition challenging. We conducted a study (n=72) in which users experienced four emotion inducing VR exergaming environments…

Watch This! Observational Learning in VR Promotes Better Far Transfer than Active Learning for a Fine Psychomotor Task

Virtual Reality (VR) holds great potential for psychomotor training, with existing applications using almost exclusively a `learning-by-doing' active learning approach, despite the possible benefits of incorporating observational learning. We compared active learning (n=26) with different variations of observational…

Dancing with the Avatars: Minimal Avatar Customisation Enhances Learning in a Psychomotor Task

Virtual environments can support psychomotor learning by allowing learners to observe instructor avatars. Instructor avatars that look like the learner hold promise in enhancing learning; however, it is unclear whether this works for psychomotor tasks and how similar avatars need to be. We investigated `minimal’ custo…

FakeForward: Using Deepfake Technology for Feedforward Learning

Videos are commonly used to support learning of new skills, to improve existing skills, and as a source of motivation for training. Video self-modelling (VSM) is a learning technique that improves performance and motivation by showing a user a video of themselves performing a skill at a level they have not yet achieve…

Realism and Field of View Affect Presence in VR but Not the Way You Think

Presence is one of the most studied and most important variables in immersive virtual reality (VR) and it influences the effectiveness of many VR applications. Separate bodies of research indicate that presence is determined by (1) technical factors such as the visual realism of a virtual environment (VE) and the fiel…

Vergence Matching: Inferring Attention to Objects in 3D Environments for Gaze-Assisted Selection

Gaze pointing is the de facto standard to infer attention and interact in 3D environments but is limited by motor and sensor limitations. To circumvent these limitations, we propose a vergence-based motion correlation method to detect visual attention toward very small targets. Smooth depth movements relative to the u…

Imagine That! Imaginative Suggestibility Affects Presence in Virtual Reality

Personality characteristics can affect how much presence an individual experiences in virtual reality, and researchers have explored how it may be possible to prime users to increase their sense of presence. A personality characteristic that has yet to be explored in the VR literature is imaginative suggestibility, th…
