In this study, we introduce a novel shared-control system for key-hole docking operations, combining a commercial camera with occlusion-robust pose estimation and a hand-eye information fusion technique. This system is used to enhance docking precision and force-compliance safety. To train a hand-eye information fusion network model, we generated a self-supervised dataset using this docking system. After training, our pose estimation method showed improved accuracy compared to traditional methods, including observation-only approaches, hand-eye calibration, and conventional state estimation filters. In real-world phantom experiments, our approach demonstrated its effectiveness with reduced position dispersion (1.23 $\pm$ 0.81 mm vs. 2.47 $\pm$ 1.22 mm) and force dispersion (0.78 $\pm$ 0.57 N vs. 1.15 $\pm$ 0.97 N) compared to the control group. These advancements in semi-autonomy co-manipulation scenarios enhance interaction and stability. The study presents an anti-interference, steady, and precise solution with potential applications extending beyond laparoscopic surgery to other minimally invasive procedures.

Tracking forearm movement via measured physiological signals is crucial for understanding human motor control mechanism. Current methods mainly use muscle-derived signals to predict arm movements while often overlooking the potential role of gaze attention, which is important for hand-eye coordination and instant and continuous motion planning and execution. In this study, we explored the impact of gaze on motion tracking.

Augmented reality (AR) has significant potential to enhance the identification of critical locations during endoscopic surgeries, where accurate endoscope calibration is essential for ensuring the quality of augmented images. In optical-based surgical navigation systems, asynchrony between the optical tracker and the endoscope can cause the augmented scene to diverge from reality during rapid movements, potentially misleading the surgeon-a challenge that remains unresolved. In this paper, we propose a novel spatial-temporal endoscope calibration method that simultaneously determines the spatial transformation from the image to the optical marker and the temporal latency between the tracking and image acquisition systems.
