This paper presents a collaborative pointing technique for colocated multi-user interaction in projection-based virtual environments. Our approach uses bent pick rays to allow users to collaboratively work together without locking objects. Moreover, a user can manipulate distant objects in immediate reach, using a Scaled-Grab technique. The main purpose of the bent pick ray is to provide continuous visual user feedback, keeping a user informed about the collaborative manipulation.
