Abstract

In this thesis, we explore some of the effects of virtual environment displays, specifically
the head-mounted display (HMD) and the Cave Automatic Virtual Environment (CAVE),
on 3D interaction tasks involving selection and manipulation. The motivation for this
thesis comes from the lack of previous work that has studied the effects of differences
between the HMD and the CAVE on 3D interaction tasks. We conducted three user
studies to determine how the differences between these two displays affect selection and
manipulation in a 3D environment. Our first study demonstrates that 3D selection and
manipulation tasks can be affected by the display type. Our second user study shows that
task performance can suffer when a selection and manipulation technique is migrated to a
display for which it is not intended. The third user study we conducted suggests that we
can modify a selection and manipulation technique and improve its usability in the
display to which it is migrated. We conclude with a set of guidelines to ease the
migration of selection and manipulation techniques from the HMD to the CAVE while
trying to maintain usability.
