Input/Manipulation in 3D Environments



Motivated by applications in telerobotics, virtual reality and interactive 3D computer graphics, this research programme investigates human factors issues associated with 6 degree-of-freedom (DOF) input techniques for object manipulation in 3D environments. A review of a large body of literature, covering research in teleoperation and virtual environments, human computer interaction, manual control and tracking, motor behaviour and experimental psychology, has indicated that many theoretical and practical issues remain inconclusive. To conceptually classify 6DOF controllers, we propose a design space model with three taxonomic dimensions: mapping relationship (position vs. rate control), sensing mode (ranging from isotonic to elastic to isometric) and degree of integration. A series of experimental studies have been conducted on the basis of this taxonomic framework. See following publications for the details of this project.
