Temporal Sensitivity and Latency During Teleoperation: Using Track Clearance to Understand Errors in Future...

Area of Science:

• Human-Computer Interaction
• Robotics
• Psychology

Background:

• Teleoperation tasks are hindered by communication latency, impacting operator performance.
• Individual differences in time perception have previously predicted performance in latency-affected tasks.
• This study extends this by examining how time perception relates to movement over/underestimation in varying route widths.

Purpose of the Study:

• To investigate the impact of individual time perception differences on task performance during teleoperation with induced latency.
• To determine if time perception predicts movement over/underestimation in routes of varying widths under latency.

Main Methods:

• Participants performed a time estimation task with short visual stimuli (≤2s).
• Participants completed a route navigation task using a virtual cube under varying latency conditions.
• Route navigation trials included different horizontal clearance widths (4-10m).

Main Results:

• Latency interacted with time estimation and route clearance on trial-level performance (e.g., completion time).
• Interactions were also observed at the action-level (e.g., time spent moving per move event).
• Observed effects were not consistently in the predicted direction.

Conclusions:

• Route clearance and timing significantly affect teleoperation performance at both trial and action levels.
• The study highlights the complex interplay between latency, environmental factors, and individual perception.
• Further research is needed to understand how these factors influence movement strategy selection.
