Moving Towards Generally Applicable Redirected Walking
نویسندگان
چکیده
Walking is the most natural way of moving within a virtual environment (VE). Mapping the user’s movement one-to-one to the real world clearly has the drawback that the limited range of the tracking sensors and a rather small working space in the real word restrict the users’ interaction. In this paper we introduce concepts for virtual locomotion interfaces that support exploration of large-scale virtual environments by redirected walking. Based on the results of a user study we have quantified to which degree users can unknowingly be redirected in order to guide them through an arbitrarily sized VE in which virtual paths differ from the paths tracked in the real working space. We describe the concepts of generic redirected walking in detail and present implications that have been derived from the initially conducted user study. Furthermore we discuss example applications from different domains in order to point out the benefits of our approach.

In immersive virtual environments (IVEs) users can control their virtual viewpoint by moving their tracked head and by walking through the real world. Usually, movements in the real world are mapped one-to-one to virtual camera motions. With redirection techniques, the virtual camera is manipulated by applying gains to user motion so that the virtual world moves differently than the real world....
متن کاملGeneralised Algorithms for Redirected Walking in Virtual Environments
Several authors have identified benefits from allowing users to move through a virtual environment (VE) by walking in the real world. However implementation of this approach can be problematic, particularly for largescale VEs, primarily because of the need to avoid the user colliding with real-world obstacles. 'Redirected walking'[1] offers a possible solution to this problem — this algorithm d...
متن کاملVelocity-dependent curvature gain and avatar use for Redirected Walking
We investigated in a study whether humans’ sensitivity to curved walking is affected by their walking velocity. Amongst other techniques, redirecting users of an immersive virtual environment on a curved path is part of the so-called ’Redirected Walking’. We conducted an experiment in which 12 participants walked specific curvatures at given speeds in a VR. We found that people are significantl...
