Redirection or redirected walking is a software-based approach to addressing this problem 4. Because VEs are often larger in size than the available physical space, collisions with physical boundaries become an issue. Due to the HMD, the user is blind to real world obstacles like walls and other objects in the physical room. While this approach produces the exact sensation of real walking, a new problem arises. Position tracking technology offers the possibility to translate real walking movements into virtual movements 3. While such solutions made it possible to “walk” infinitely far in a VE, they are still a cumbersome approximation to real walking. This crude simulation of locomotion was quickly followed by more sophisticated solutions using treadmill-like devices that allow users to physically walk on the spot in order to move through virtual space 1, 2. Early attempts to overcome this locomotion problem made use of keyboards and joysticks thus engaging the hands for a task meant, in reality, for the legs. While virtual worlds can easily be expanded infinitely, physical locomotion remains constrained by the dimensions of the available room. It concerns the user’s navigation through large VEs. There is, however, one obstacle to a full-blown immersion, dubbed the “locomotion problem”. Virtual reality (VR) applications using head mounted displays (HMDs) allow users to deeply immerse in a virtual environment (VE). We discuss how future interdisciplinary studies, merging the fields of virtual reality and psychology, may help improving virtual reality applications and simultaneously deepen our understanding of how humans process multisensory conflicts during locomotion. This supports the interpretation of users’ neglect of redirection manipulations as a “visual capture of gait”. The performance in the rod-and-frame test, a classical measure of visual dependency regarding postural information, showed the strongest relation to redirection detection thresholds: The higher the visual dependency, the higher the detection threshold. We report relations between individual thresholds and measures of multisensory weighting (visually-assisted postural stability (Romberg quotient), subjective visual vertical (rod-and-frame test) and illusory self-motion (vection)). Addressing this question, we administered several perceptual-cognitive tasks to healthy participants, whose thresholds of detecting redirection in a virtual environment were also determined. An important yet unsolved question concerns individual differences in the ability to detect redirection. Apart from its applied relevance, redirected walking is an attractive paradigm to investigate human perception and locomotion. This is achieved by manipulating users’ walking trajectories through visual rotation of the virtual surroundings, without users noticing this manipulation. They're fast, professional and friendly.Redirected walking allows users of virtual reality applications to explore virtual environments larger than the available physical space. Thank you for your high-quality work, professionalism, and quick turn around!” Chrissy Kelleher Landlord and Property Manager The feedback that we received, and the preference for the properties with the video and photos was amazing! We just had them back out to photograph other properties and couldn't be more excited to start off the tourist season with a fresh look. “We first hired HouseLens (Baltimore) for our rental property two years ago. The photos and videos are always clear and pristine.” Mike & Tara EXP Realty I appreciate the care they demonstrate for the client’s personal property and the concern for producing the perfect photos. “HouseLens has been our number one strategy for getting homes SOLD for the past 9 years! We make it a practice to not put a home on the market without Houselens! They are efficient, knowledgeable, and helpful. Great feedback and easy to work with! Thank you for the consistency!” Angie Delboy Realtor & Consultant at RE/MAX Gateway “The walk-through video is so helpful! Even if people are local, everyone is busy so the Walk Through video allows potential home buyers to get an accurate picture of hallways, sunniness, which room opens to which room, etc.
