Taxonomy Motivation

· A taxonomy can provide developers with a (more) objective framework within which to make choices about locomotion

· Bowman’s taxonomy (Direction/Target selection, Velocity/Acceleration, Input conditions)

· New taxonomy, main difference from Bowman – the VR system must be integral to the taxonomy, because virtual locomotion always occurs in a VE.

· Most prominent features of the VR system are input devices and output devices

· These should be considered because they can lead to fundamentally different experiences for the user

· Include translational and rotational aspects of movement separately

· Rotation and translation are divided into virtual and physical sub-categories
