3D Interaction Techniques for Bimanual Haptics in Virtual Environments

Bimanual haptics is a specific kind of multi-finger interaction that focuses on the use of both hands simultaneously. Several haptic devices permit this form of interaction, but they are subject to a certain number of limitations for interacting with virtual environments (VEs), notably workspace size issues and manipulation difficulties with single-point interfaces. Interaction techniques exist to overcome these limitations and allow users to perform specific two-handed tasks, such as the bimanual exploration of large VEs and grasping of virtual objects. These interaction techniques will be reviewed in this chapter.
