“…Within HCI, this has focused on haptic illusions [3,8] and walking illusions [21,47], with the intention of enhancing the haptic or spatial richness of the virtual environment. We believe the moment of exit in these illusions is especially interesting, as it corresponds to the moment that users realize they faced an illusion, and must quickly re-orient themselves within the real environment.…”

Research on virtual reality (VR) has studied users' experience of immersion, presence, simulator sickness, and learning effects. However, the momentary experience of exiting VR and transitioning back to the real-world is not well understood. Do users become self-conscious of their actions upon exit? Are users nervous of their surroundings? Using explicitation interviews, we explore the moment of exit from VR across four applications. Analysis of the interviews reveals five components of experience: space, control, sociality, time, and sensory adaptation. Participants described spatial disorientation, for example, regardless of the complexity of the VR scene. Participants also described a window across which they exit VR, for example mentally first and then physically. We present six designs for easing or heightening the exit experience, as described by the participants. Based on these findings, we further discuss the 'moment of exit' as an opportunity for designing engaging and enhanced VR experiences.

“…There can be many different experiences bound to the realization of this deception. For example, participants may exhibit surprise [8], or mild-discomfort [21]. The way in which these experiences arise remains unclear, however.…”

“…The workshop consisted of four steps: instruction, brainstorming, synthesizing, and voting. In the instruction step, we first introduced the VPPMs in VR by presenting examples in HCI and VR research, such as Haptic Retargeting [3], Body Follows Eye [53], and redirected walking [21,61]. Next, we presented our goal -speculate on the potentially abusive VPPMs that could manipulate the VR user's body motions to induce physical harm.…”

“…A popular example of such technique is redirected walking [44,60,61], steering the VR user's physical walking path by interactively and imperceptibly rotating the virtual scene. One can use slow-speed translation/rotation gain below the user's perception threshold or manipulate the stereo image in a see-through HMD [21] to achieve the effect. Redirected touching [23] and redirected haptics [3,13] re-purpose the VR user's hand to a passive haptic prop by manipulating the visual of the user's arm or the virtual scene.…”

“…We used a Metronome to help participants maintaining walking speed during experiments. Participants practiced using metronome before the experiments [21], [22]. As further (A) case 1 and 3 0.928 (B) case 1+2 and 3+4 0.798 orientation, the ground was marked with a tape in distances of 1 meter and 50cm between transmitter and receiver.…”

While most RF-sensing approaches proposed in the literature rely on short-distance indoor point-to-point instrumentations, actual large-scale installation of RF sensing suggests the use of ubiquitously available cellular systems. In particular, the 5th generation of the wireless communication standard (5G) is envisioned as a universal communication means also for Internet of Things devices. In this paper, we investigate environmental perception capabilities in cellular systems, with special focus on the upcoming 5G communications standard. In particular, we analyze the perception capabilities of existing cellular installations in the GSM band, which is expected to be used for 5G IoT. Our instrumentation exploits a passive system capitalizing on environmental RF-noise. In addition, utilizing a prototypical 5G system with 52 OFDM carriers over 12.48 MHz bandwidth at 3.45 GHz, we consider the impact of the number and choice of channels and compare the recognition performance with acceleration-based sensing. Our results in realistic settings with five subjects suggest that accurate recognition of activities and environmental situations can be a reliable implicit service of future 5G installations.
