Evaluation of a new virtual reality micro-robotic cell injection training system

This study considers a virtual reality (VR) micro-robotic cell injection training system developed to reduce the time and cost required for a trainee to become proficient in cell injection. The VR environment replicates a micro-robotic cell injection setup to be interacted with and controlled using either a keyboard or haptic device. Using these two input control methods, user training evaluation experiments were designed and conducted to evaluate trainee performance. The performance improvement of 13 participants after undergoing training was analyzed. Results demonstrate that the participants attained higher accuracy and success rates when utilizing the haptic device control method than when applying the keyboard control method. All participants successfully performed the required task when employing the haptic device control method with haptic guidance enabled.
