INTELLIGENT HANDHELD INSTRUMENT FOR MICROSURGERY & BIOTECH MICROMANIPULATION
To enhance human positioning tasks requiring micro level accuracy (e.g. microsurgery and cell micromanipulation). The intelligent instrument will detect motion, distinguish undesired and intended motion and provide real-time active error compensation by deflecting its tip to compensate physiological tremor and other erroneous movement components.

Assessment and Training System for Micromanipulation Tasks in Surgery
Human accuracy limitations due to physiological tremor is a concern in microsurgery (e.g., eye, hand and neuro-surgery). This restricts the types of feasible microsurgical procedures, making it necessary to train apprentice surgeons and assess their performances. This project will investigate the causes of non-voluntary deviations hindering the quality of interventions, and develop a virtual reality based training system for training microsurgeons to perform manipulation tasks under a microscope.

OPTICAL MICRO-MOTION TRACKER
Detecting micro motion of a microsurgical instrument in real time to aid training of new surgeons and discover more findings about tremor nature of human's hand. [read more ...]
