TH3D: A Two-Handed Interaction Framework for Desktop Virtual Environment
This paper describes a two-handed interaction framework for desktop virtual environment, called TH3D. The design goal of this framework is to support the device-independent, task-centered, and fast development of two-handed applications on desktop computers. Existing research on two-handed interaction focuses mainly on specific interaction techniques and fails to achieve this goal. The authors' framework is characterized by its multi-layer design applied to two-handed interaction, including the normalization of raw input data, interaction primitive and task construction, and an efficient, built-in, two-handed interaction technique that integrates the benefits of both egocentric and exocentric interactions.
