Hand gesture is a new and promising interface for locomotion in virtual environments. While several previous studies have proposed different hand gestures for virtual locomotion, little is known about their differences in terms of performance and user preference in virtual locomotion tasks. In the present paper, we presented three different hand gesture interfaces and their algorithms for locomotion, which are called the Finger Distance gesture, the Finger Number gesture and the Finger Tapping gesture. These gestures were inspired by previous studies of gesture-based locomotion interfaces and are typical gestures that people are familiar with in their daily lives. Implementing these hand gesture interfaces in the present study enabled us to systematically compare the differences between these gestures. In addition, to compare the usability of these gestures to locomotion interfaces using gamepads, we also designed and implemented a gamepad interface based on the Xbox One controller. We compared these four interfaces through two virtual locomotion tasks. These tasks assessed their performance and user preference on speed control and waypoints navigation. Results showed that user preference and performance of the Finger Distance gesture were comparable to that of the gamepad interface. The Finger Number gesture also had close performance and user preference to that of the Finger Distance gesture. Our study demonstrates that the Finger Distance gesture and the Finger Number gesture are very promising interfaces for virtual locomotion. We also discuss that the Finger Tapping gesture needs further improvements before it can be used for virtual walking.

“…In contrast, the degree of embodiment in the locomotion interface seems to independently have a positive impact on the contribution to sickness. This is, compared to using, e.g., hand-based controllers, using more embodied locomotion interfaces, such as leaning-based paradigms that provide at least some vestibular cues during simulated accelerations, can help to reduce cybersickness [14,18,19], potentially due to the reduced inter-sensory cue conflict. This also illustrates that the effect of more embodied interaction is not merely generated by the pure amount of bodily movements and involved body parts, but that the movements necessary to use the interface have to match the simulated self-motions, or otherwise can have the opposite effect [20].…”

“…Providing at least some minimal physical motion cues (e.g., using motion cueing in vehicle simulation) and, in particular, vestibular cues have been shown to significantly enhance self-motion perception [39][40][41][42]. Although we are not aware of any published studies explicitly comparing vection in standing versus seated VR users, research has shown that leaning-based interfaces can enhance vection [19,[43][44][45]. Hence, we hypothesized that leaning-based interfaces that provide a larger leaning range could provide earlier and more compelling vection; thus, standing and other postures that provide more movement possibilities and embodied self-motion cues might also help to enhance vection, as illustrated in Figure 11.…”

Virtual Reality (VR) users typically either sit or stand/walk when using VR; however, the impact of this is little researched, and there is a lack of any broad or systematic analysis of how this difference in physical posture might affect user experience and behavior. To address this gap, we propose such a systematic analysis that was refined through discussions and iterations during a dedicated workshop with VR experts. This analysis was complemented by an online survey to integrate the perspectives of a larger and more diverse group of VR experts, including developers and power users. The result is a validated expert assessment of the impact of posture and degree of embodiment on the most relevant aspects of VR experience and behavior. In particular, we posit potential strong effects of posture on user comfort, safety, self-motion perception, engagement, and accessibility. We further argue that the degree of embodiment can strongly impact cybersickness, locomotion precision, safety, self-motion perception, engagement, technical complexity, and accessibility. We provide a compact visualization of key findings and discuss areas where posture and embodiment do or do not have a known influence, as well as highlight open questions that could guide future research and VR design efforts.

“…However, during prolonged use, the reference point can keep moving away from the center of the tracked space and eventually out of the tracking space. Hashemian et al (2020) developed a seated leaning-based interface, "HeadJoystick," with a virtual quadcopter model. In their model, a user freely rotates the swivel chair to control the simulated rotation.…”

When users in virtual reality cannot physically walk and self-motions are instead only visually simulated, spatial updating is often impaired. In this paper, we report on a study that investigated if HeadJoystick, an embodied leaning-based flying interface, could improve performance in a 3D navigational search task that relies on maintaining situational awareness and spatial updating in VR. We compared it to Gamepad, a standard flying interface. For both interfaces, participants were seated on a swivel chair and controlled simulated rotations by physically rotating. They either leaned (forward/backward, right/left, up/down) or used the Gamepad thumbsticks for simulated translation. In a gamified 3D navigational search task, participants had to find eight balls within 5 min. Those balls were hidden amongst 16 randomly positioned boxes in a dark environment devoid of any landmarks. Compared to the Gamepad, participants collected more balls using the HeadJoystick. It also minimized the distance travelled, motion sickness, and mental task demand. Moreover, the HeadJoystick was rated better in terms of ease of use, controllability, learnability, overall usability, and self-motion perception. However, participants rated HeadJoystick could be more physically fatiguing after a long use. Overall, participants felt more engaged with HeadJoystick, enjoyed it more, and preferred it. Together, this provides evidence that leaning-based interfaces like HeadJoystick can provide an affordable and effective alternative for flying in VR and potentially telepresence drones.
