Overview

Demonstrates accurate manual tracking in participants relying on extraretinal information while tracking targets.

Key Points

  • This research aims to examine the role of extraretinal signals during manual tracking in comparison to retinal inputs.
  • Conducted a study with 26 participants to compare eye and hand tracking performance.
  • Participants tracked targets under three conditions: SINGLE, DOUBLE, and FIX.
  • Analyzed tracking performance to assess the impact of congruence between eye and hand movements.
  • Manual tracking performance was significantly better in the DOUBLE condition compared to FIX.
  • Tracking in the DOUBLE condition was nearly equivalent to the SINGLE condition.
  • Smooth pursuit contributed more than saccades to the overall eye movements, indicating its primary role in providing extraretinal information.
