DeFT-Net: Dual-Window Extended Frequency Transformer for Rhythmic Motion Prediction
Enabling online virtual reality (VR) users to dance and move in a way that mirrors the real-world necessitates improvements in the accuracy of predicting human motion sequences paving way for an immersive and connected experience. However, the drawbacks of latency in networked motion tracking present a critical detriment in creating a sense of comp...
VR-based body tracking to stimulate musculoskeletal training
Published in Current Directions in Biomedical Engineering
Training helps to maintain and improve sufficient muscle function, body control, and body coordination. These are important to reduce the risk of fracture incidents caused by falls, especially for the elderly or people recovering from injury. Virtual reality training can offer a cost-effective and individualized training experience. We present an a...
Gamified Virtual Reality Training for Visuospatial Ability in Neuroradiology
Published in Current Directions in Biomedical Engineering
During neuroradiological interventions such as treating intracranial aneurysms, neuroradiologists have to navigate a catheter in the 3D anatomy while watching a 2D projection of the vessels. To train this visuospatial ability, we present a virtual reality application where the user has to identify anatomically relevant positions on the Circle of Wi...
Virtual Crowds Rheology: Evaluating the Effect of Character Representation on User Locomotion in Crowds
Crowd data is a crucial element in the modeling of collective behaviors, and opens the way to simulation for their study or prediction. Given the difficulty of acquiring such data, virtual reality is useful for simplifying experimental processes and opening up new experimental opportunities. This comes at the cost of the need to assess the biases i...
Enhancing Operating Theatre Conduct through Virtual Reality Simulation
Published in Current Directions in Biomedical Engineering
In hospital operating theatres, inadvertent violations of behavioural rules by novices may increase risk. Virtual reality (VR) can provide a training environment to ease the burden for healthcare professionals. Our work develops and tests a VR training program for correct operating room (OR) etiquette. The VR simulator incorporates realistic 3D mod...
Does Multi-Actuator Vibrotactile Feedback Within Tangible Objects Enrich VR Manipulation?
Rich, informative and realistic haptic feedback is key to enhancing Virtual Reality (VR) manipulation. Tangible objects provide convincing grasping and manipulation interactions with haptic feedback of e.g., shape, mass and texture properties. But these properties are static, and cannot respond to interactions in the virtual environment. On the oth...
Ecotourism as an effective direction for a healthy lifestyle
Published in BIO Web of Conferences
Ecotourism is one of the effective ways to ensure a healthy lifestyle. The paper is devoted to the study of the possibilities of developing ecotourism at the Crimean resorts in the northern Black Sea region of Russia. Today, eco-tourism is becoming increasingly popular. Every year more people are looking for outdoor recreation, away from noisy citi...

A Comparative Study Between a Large-Screen and a HMD using Wind Representations in Virtual Reality
In this study, we investigated the representation of wind in urban spaces through computational fluid dynamics simulations in virtual environments (VE). We compared wind perception (force and direction) as well as the sense of presence and embodiment in VE using different display technologies: Head-Mounted Displays (HMD) and large-screens, and with...
