SUMMARY:The Continuity of Locomotion: Rethinking Conventions for Locomotio
 n and Its Visualization in Shared Virtual Reality Spaces
DESCRIPTION:Technical Papers\n\nThe Continuity of Locomotion: Rethinking C
 onventions for Locomotion and Its Visualization in Shared Virtual Reality 
 Spaces\n\nFreiwald, Schmidt, Riecke, Steinicke\n\nNatural interaction betw
 een multiple users within a shared virtual environment (VE) relies on each
  others' awareness of the current position of the interaction partners. Th
 is, however, cannot be warranted when users employ noncontinuous locomotio
 n techniques, such as teleportation, which may cause confusion among bysta
 nders.\n\nIn this paper, we pursue two approaches to create a pleasant exp
 erience for both the moving user and the bystanders observing that movemen
 t. First, we will introduce a Smart Avatar system that delivers continuous
  full-body human representations for noncontinuous locomotion in shared vi
 rtual reality (VR) spaces. Smart Avatars imitate their assigned user's rea
 l-world movements when close-by and autonomously navigate to their user wh
 en the distance between them exceeds a certain threshold, i.e., after the 
 user teleports. As part of the Smart Avatar system, we implemented four av
 atar transition techniques and compared them to conventional avatar locomo
 tion in a user study, revealing significant positive effects on the observ
 ers' spatial awareness, as well as pragmatic and hedonic quality scores.\n
 \nSecond, we introduce the concept of Stuttered Locomotion, which can be a
 pplied to any continuous locomotion method. By converting a continuous mov
 ement into short-interval teleport steps, we provide the merits of non-con
 tinuous locomotion for the moving user while observers can easily keep tra
 ck of their path. Thus, while the experience for observers is similarly po
 sitive as with continuous motion, a user study confirmed that Stuttered Lo
 comotion can significantly reduce the occurrence of cybersickness symptoms
  for the moving user, making it an attractive choice for shared VEs. We wi
 ll discuss the potential of Smart Avatars and Stuttered Locomotion for sha
 red VR experiences, both when applied individually and in combination.\n\n
