“…Several virtual walking systems that do not necessitate active leg movements have been developed using vection (Lécuyer et al, 2006;Terziman et al, 2012;Ikei et al, 2015;Kitazaki et al, 2019). Integrating simulated camera motions (similar to perspective jitter) with the vection stimulus, such as an expanding radial flow, improves the walking sensation of seated users (Lécuyer et al, 2006).…”

“…Integrating simulated camera motions (similar to perspective jitter) with the vection stimulus, such as an expanding radial flow, improves the walking sensation of seated users (Lécuyer et al, 2006). By conveying tactile sensations to the feet in addition to vection, the pseudo-sensation of virtual walking sensation can be induced (Terziman et al, 2012;Ikei et al, 2015;Kitazaki et al, 2019). Kitazaki et al (2019) demonstrated that foot vibrations that were synchronous to the oscillating actual optic flow induced not only the sensation of self-motion but also the sensations of walking, leg action, and telepresence.…”

Walking is a fundamental physical activity in humans. Various virtual walking systems have been developed using treadmill or leg-support devices. Using optic flow, foot vibrations simulating footsteps, and a walking avatar, we propose a virtual walking system that does not require limb action for seated users. We aim to investigate whether a full-body or hands-and-feet-only walking avatar with either the first-person (experiment 1) or third-person (experiment 2) perspective can convey the sensation of walking in a virtual environment through optic flows and foot vibrations. The viewing direction of the virtual camera and the head of the full-body avatar were linked to the actual user's head motion. We discovered that the full-body avatar with the first-person perspective enhanced the sensations of walking, leg action, and telepresence, either through synchronous or asynchronous foot vibrations. Although the hands-and-feet-only avatar with the first-person perspective enhanced the walking sensation and telepresence, compared with the no-avatar condition, its effect was less prominent than that of the full-body avatar. However, the full-body avatar with the third-person perspective did not enhance the sensations of walking and leg action; rather, it impaired the sensations of self-motion and telepresence. Synchronous or rhythmic foot vibrations enhanced the sensations of self-motion, waking, leg action, and telepresence, irrespective of the avatar condition. These results suggest that the full-body or hands-and-feet avatar is effective for creating virtual walking experiences from the first-person perspective, but not the third-person perspective, and that the foot vibrations simulating footsteps are effective, regardless of the avatar condition.

“…Lécuyer et al [29] simulated camera motion as perspective jitter to induce a walking sensation, and Terziman et al [30] utilized artificial visual and tactile vibrations corresponding to footsteps during virtual walking (the "King-Kong effect"). The FiveStar or Five Senses Theatre system [32] presents proprioceptive and tactile sensations of the body passively evoked by actuators, in addition to multisensory stimuli, such as vision, audition, air flow, and smells. Electrical stimulation of the muscles of the legs [33] and small motions of the lower limbs [34] or the entire body [35] by mechanical actuators can elicit a virtual walking sensation.…”

“…Rhythmic stimulation to the feet may induce spinal central pattern generators to produce an active walking sensation, which is expected to contribute to walking rehabilitation (Chéron et al., 2012; Gravano et al., 2011). A VR system was developed by utilizing rhythmic stimulations on the feet and small movements of the feet, legs, and trunk enforced by actuators with multisensory presentations of airflow, smell, changing sounds, and three-dimensional video images (Ikei, Abe, Hirota, & Amemiya, 2012; Ikei et al., 2015). However, there is no psychological evidence on the strength of sensory perception of walking by users and the critical factors affecting the walking sensations.…”

This article reports the first psychological evidence that the combination of oscillating optic flow and synchronous foot vibration evokes a walking sensation. In this study, we first captured a walker’s first-person-view scenes with footstep timings. Participants observed the naturally oscillating scenes on a head-mounted display with vibrations on their feet and rated walking-related sensations using a Visual Analogue Scale. They perceived stronger sensations of self-motion, walking, leg action, and telepresence from the oscillating visual flow with foot vibrations than with randomized-timing vibrations or without vibrations. The artificial delay of foot vibrations with respect to the scenes diminished the walking-related sensations. These results suggest that the oscillating visual scenes and synchronous foot vibrations are effective for creating virtual walking sensations.
