“…Nilsson et al [16] performed a study investigating how three different forms of gestural input for controlling WIP locomotion compared to one another in terms of naturalness, presence and positional drift [16]. The compared gestures were: 1) The gesture most commonly used in relation to WIP, namely, a gesture where the user alternately lifts each foot off the ground by raising the thighs in front of the body.…”

If Walking-in-place (WIP) techniques are to be considered a useful way of facilitating virtual locomotion, it is crucial that the user remains stationary with respect to the physical environment. However, it has recently been documented that WIP locmotion may lead to Unintended Positional Drift (UPD). Users walking in place while wearing a head-mounted display tend to physically drift in the direction which they are headed within the virtual environment. This paper details a within-subjects study evaluating different methods for minimizing UPD. The study included 14 conditions: 13 different types of feedback informing the user that a certain amount of drift had occurred and a control condition devoid of feedback. The feedback differed in terms of sensory modality (auditory, visual or audiovisual), onset mode (gradual or sudden) and presentation mode (either the feedback constituted a warning or a deprivation of the stimuli used to represent the virtual world). Finally, a condition providing passive haptic feedback (a circular carpet) was included. The types of feedback were assessed in terms of how effectively they reduced UPD as well as how helpful and intrusive they were perceived. The results suggest that both passive haptic feedback and feedback types with gradual onset are the most efficient at controlling the user's physical movement. However, the passive haptic feedback was regarded as more helpful and perceived as less disruptive than some of the feedback types with a gradual onset.

“…Generally it is possible to distinguish between systems that detect discrete gait events (e.g., foot-ground contact) and systems that track continuous movement (e.g., foot position and velocity) [14]. Physical walking platforms fall into the former category.…”

“…The direction of heading can either be derived from the data used for proxy step detection, as was the case in relation to the physical platforms described in subsection 3.1, or it can be obtained from additional trackers mounted on the user. At least five different approaches to steering during WIP locomotion have been used: joystick-controlled steering, gaze-directed steering, torso-directed steering, hip-directed steering, and feetdirected steering [9,14,33,34]. A potential limitation of using joysticks or similar peripherals for steering is that this will deprive the user of the proprioceptive and kinesthetic feedback produced by whole body turns [28].…”

“…This motivated us to perform two within-subjects studies exploring alternative gestural input for WIP locomotion. The first study (n=27 ) [14] compared three gestures: the common WIP gesture, Wiping (alternately bending each knee as if wiping the feet on a doormat), and Tapping (alternately tapping each heel against the ground). The second study [15] (n=20 ) was focused on gestures devoid of explicit leg motion and compared four gestures: the common WIP gesture, Hip Movement (alternately swinging the hips to the left and right), Arm Swinging (alternately swinging each arm back and forth), and keyboard input (while standing the user pressed a button to move).…”

“…These techniques enable user's to travel through virtual worlds by performing stepping-like moments on the spot that serve as a proxy for real steps. Particularly, we present a taxonomy of virtual travel tecniques, review past work on WIP locomotion, and summarize our recent work which has sought to increase the perceived naturalness of WIP locomotion [14][15][16][17][18][19][20].…”

There are many techniques for locomotion and navigation that can support the exploration of large virtual environments in a limited physical area. Previous studies focused on measuring curvature gains and bending gains applied to the walking direction in the real world. However, the effects of different moving techniques and their relationship with shapes and patterns of virtually moving paths have not been studied extensively before. In this study, we present our experimental results on how users perceive two different traveling-in-place techniques with different bending gains of moving paths using a hybrid electric bike simulator. Moreover, the impact of different factors including road textures, road widths, and road curve directions and their relationships with the techniques are investigated. Generally, users could travel along a curve without noticing with a point of subjective equality (PSE) at bending angle β = 1.42 o , and a just-noticeable difference (JND) of 0.75 o for a movement at around 20 km/h during 5 seconds. In addition, movement technique, curve direction, and future travel path significantly affected how they perceived the curvature of their travel path.
