Abstract

When developing our Immersive Virtual Environment Rehabilitation Treadmill (IVERT) system (Figure 1), we observed the well known phenomenon of visuals feeling "too slow" compared to walking speed (Durgin 2005). The work reported here was motivated by needing a factor, the optical flow multiplier (OFM), to multiply by the treadmill speed to generate a viewpoint/visual speed that "felt right" to the IVERT users. Our most frequent use case will be the therapist setting the treadmill speed and then the program multiplying treadmill speed by the OFM to generate the viewpoint speed.

Walking in Virtual Reality: Effects of Manipulated Visual Self-Motion on Walking Biomechanics

Walking constitutes the predominant form of self-propelled movement from one geographic location to another in our real world. Likewise, walking in virtual environments (VEs) is an essential part of a users experience in many application domains ...
Controlling the Walking Speed in Limit Cycle Walking

“Limit Cycle Walking” is a relatively new paradigm for the design and control of two-legged walking robots. It states that achieving stable periodic gait is possible without locally stabilizing the walking trajectory at every instant in ...
Effects of Virtual Reality Immersion and Walking Speed on Coordination of Arm and Leg Movements

The present study focused on the impact of immersive virtual reality (VR) technology on the coordination dynamics of walking, because of VR-induced symptoms and effects (e.g., motion sickness, postural instability, and disorientation) reported in the ...
