Previous work has documented that limitations of current stereo display systems affect depth perception. We performed an experiment to understand if such stereo display deficiencies affect 3D pointing for targets in front of a screen and close to the user, i.e., in peri-personal space. Our experiment compares isolated movements with and without a change in visual depth for virtual targets. Results indicate that selecting targets along the depth axis is slower and has less throughput than laterally positioned targets.
