Multimodal Interfaces for Effective Teleoperation
Research in multi-modal interfaces aims to provide solutions to immersion and
increase overall human performance. A promising direction is combining
auditory, visual and haptic interaction between the user and the simulated
environment. However, no extensive comparisons exist to show how combining
audiovisuohaptic interfaces affects human perception reflected on task
performance. Our paper explores this idea. We present a thorough,
full-factorial comparison of how all combinations of audio, visual and haptic
interfaces affect performance during manipulation. We evaluate how each
interface combination affects performance in a study (N=25) consisting of
manipulating tasks of varying difficulty. Performance is assessed using both
subjective, assessing cognitive workload and system usability, and objective
measurements, incorporating time and spatial accuracy-based metrics. Results
show that regardless of task complexity, using stereoscopic-vision with the
VRHMD increased performance across all measurements by 40% compared to
monocular-vision from the display monitor. Using haptic feedback improved
outcomes by 10% and auditory feedback accounted for approximately 5%
improvement.Comment: 15 pages, 28 figures, 5 tables, 5 equation
