Autoethnographic Close Reading of Self-transcendent VR Experiences

Sipping the Virtual Elixir: An autoethno­graphic close read­ing of Ayahuasca Kosmik Journey a self-transcendent vir­tual expe­ri­ence. Recently self-transcendent experiences are gaining interest in the research community because of their ability to support wellbeing. Experiences of self-transcendence can be transformative, leading to a diminishment of self/ego and the feeling of unity with n...


Telepresence

How can we improve telepresence systems (such as conference robots) so they are not just "zoom on wheels" but actually allow users to feel more present and navigate more easily around remote environments?" FeetBack: Augmenting Robotic Telepresence with Haptic Feedback on the Feet Telepresence robots allow people to participate in remote spaces, yet they can be difficult to manoeuvre with people ...


HyperJump flying to combat motion sickness

HyperJumping in Virtual Vancouver: Combating Motion Sickness by Merging Teleporting and Continuous VR Locomotion in an Embodied Hands-Free VR Flying Paradigm Motion sickness, unintuitive navigation, and limited agency are critical issues in VR/XR impeding wide-spread adoption and enjoyable user experiences. To tackle these challenges, we present HyperJump, a novel VR interface merging advantages ...


Concurrent locomotion and interaction in VR

Can more embodied and leaning-based interfaces help support concurrent locomotion and interaction in VR when physical walking isn't feasible? Physical walking is often considered the gold standard for VR travel whenever feasible. However, especially for larger-scale virtual travel the free-space walking areas are typically too small, thus requiring handheld controllers to navigate, which ...


SIRIUS - Virtual Earthgazing to mitigate effects of sensory isolation

SIRIUS (Scientific International Research in Unique Terrestrial Station) is a series of on-land isolation experiments modelling long-term spaceflight in order to assess the psychophysiological effects of isolation on a crew and prepare for long-duration spaceflights, such as a trip to Mars. An 8-month-long isolation study commenced in Moscow on Nov 4th, 2021, where a crew of 6 people (from Roscosm...


Leaning-based interfaces improve ground-based VR locomotion

Hand-held VR controllers are widely available and used, however they can contribute to unwanted side-effects, such as increased cybersickness, disorientation, and cognitive load. Here, we show how a leaning-based interfaces ("HeadJoystick") can help improve user experience, usability,and performance in diverse ground-based navigation including three complementary tasks: reach-the-target, follow-th...


Integrating Continuous and Teleporting VR Locomotion into a Seamless "HyperJump" Paradigm

Here we propose a hybrid interface that allows user to seamlessly transition between a slow 'continuous' mode and a fast 'hyperjump' mode. The interface aims to maintain the immersion, presence, accuracy and spatial updating of continuous locomotion while adding the travel efficiency and minimizing the cybersickness. Continuous locomotion in VR provides uninterrupted optical flow, which mimics re...


Embodied & Intuitive Flying for VR, Gaming, and TeleOperation

Flying has been a dream for mankind for millenia - but flying interfaces for VR, gaming, and teleoperation (e.g., drones) typically rely on cumbersome double-joystick/gamepads and do not allow for intuitive and embodied flying experiences. Here, we develop low-cost embodied flying interfaces that adapt leaning-based motion cueing paradigms thus freeing up hands for additional tasks beyond just na...


NaviBoard: Efficiently Navigating Virtual Environments

Here we propose a novel and cost-effective setup of a leaning-based interface ("NaviBoard") that allows people to efficiently navigate virtual environments - with performance levels matching the gold standard of free-space walking, without any increase in motion sickness Abstract Walking has always been the most common locomotion mode for humans in the real world. As a result, it has also been co...


Gamified Research

Gamifying Research - Researchifying Games While traditional experimental paradigms offer tight stimulus control and repeatability, then tend to be a bit boring and removed from many real-world situations, which can limit real-world transferability of results. How can we bring together the methodological strenghs of research with the intrinsic motivation of playfulness and gaming? The ...
