“…Moreover, the forward viewpoint movement is updated only one time for each step by one predefined length. User testing with this system revealed that WIP can increase presence compared to classical joystick-based interaction [7], which is similar to the conclusion reached by Razzaque et al [9]. In that study, it was suggested that WIP might also increase cybersickness [7].…”

Abstract. Walking in Place (WIP) is an important locomotion technique used in virtual environments. This paper proposes a new approach to WIP, called Speed-Amplitude-Supported Walking-in-Place (SAS-WIP), which allows people, when walking along linear paths, to control their virtual speed based on footstep amplitude and speed metrics. We argue that our approach allows users to better control the virtual distance covered by the footsteps, achieve higher average speeds and experience less fatigue than when using state-of-the-art methods based on footstep frequency, called GUD-WIP. An in-depth user evaluation with twenty participants compared our approach to GUD-WIP on common travel tasks over a range of short, medium and long distances. We measured task performance using four distinct criteria: effectiveness, precision, efficiency and speed. The results show that SAS-WIP is both more efficient and faster than GUD-WIP when walking long distances while being more effective and precise over short distances. When asked their opinion via a post-test questionnaire, participants preferred SAS-WIP to GUD-WIP and reported experiencing less fatigue, having more fun and having a greater level of control when using our approach.

“…However, true physical locomotion, like walking and running, is a compelling feature in training environments because there is a direct correspondence to the locomotion and physical coordination required in real world tasks. Furthermore, true physical locomotion can provide better spatial cognition since it provides spatial cues missing from simulated movement techniques [13].…”

New opportunities emerge when mixed reality environments are augmented with wide field of view displays and full body, realtime tracking. Such systems will allow users see a correctly tracked representation of themselves in the virtual environment, and allow users to "share space" with other virtual humans in the virtual environment. Furthermore, such systems will be able to use tracking data to identify opportunities when a user's perception of the environment can be altered. This would be helpful in situations where redirection or reorientation of the user might be done to "stretch space," i.e. imperceptibly rotating the environment around the user, so that a straight-line walk becomes a curve, preventing the user from ever encountering walls in the physical space. We believe that allowing users to co-inhabit virtual spaces with virtual humans and decoupling physical size constraints from these virtual spaces are two important building blocks for effective mixed reality training experiences.

Haptics: Perception, Devices and Scenarios

View full text Add to dashboard Cite

Abstract. Potential applications of online virtual worlds are attracting the interest of many researchers around the world. One and perhaps the most famous example of such systems is Linden Lab's Second Life. Last year, sources for its client application have been released under the GPL license, allowing anyone to extend it building a modified client. This work presents an effort to explore the possibilities that haptic technologies can offer to multiuser online virtual worlds, to provide users with an easier, more interactive and immersive experience. A haptic-enabled version of the Second Life Client, supporting major haptic devices, is proposed. Two haptic-based input modes have been added which help visually impaired people to navigate and explore the simulated 3D environment by exploiting force feedback capabilities of these devices.
