Tian Zhou

Research Assistant
ISAT Lab, Purdue University

   I am currently pursing a PhD degree in the Intelligent Systems and Assistive Technologies (ISAT) Lab in the School of Industrial Engineering at Purdue University, under the supervision of Dr. Wachs. In the meantime I am pursing a MS dual-degree in the School of Electrical and Computer Engineering at Purdue University.

   My research interest lies in human robot interaction (HCI) and robot vision. More specifically, I desire to design innovative interaction and communication protocols between humans and robots, and develop new techniques leveraging on computer vision and artificial intelligence to enable an autonomous and efficient cooperation between humans and robots.

Research Experiences

Touchless telerobotic surgery–A comparative study

Teleoperated robot-assisted surgery (RAS) is becoming more popular in certain types of surgical procedures due to its dexterity, precision, high-resolution, accurate motion planning and execution capabilities, compared to traditional minimally invasive surgery which relies on hindered laparoscopic control. The most widely adopted system based on this paradigm is the daVinci robot (2014), in which the surgeon manipulates joysticks in a master console using 3D imaging for guidance. Then robotic arms mimic the surgeon’s movements on the patient’s side. Some of the drawbacks of this system are related with the user experience, since the surgeon has to retrain in order to learn how to operate cumbersome interfaces and in the process some of the intuitive hand gestures related with in situ surgery are lost.

To address this problem, we have developed an innovative system to involve touchless interfaces for telesurgery. This type of solution, when applied to robotic surgery, has the potential to allow surgeons to operate as if they were physically engaged with the surgery in-situ (as standard in traditional surgery). By relying on touchless interfaces, the system can incorporate more natural gestures that are similar to instinctive movements performed by surgeons when operating, thus enhancing the user experience and overall system performance. Sensory substitution methods are used as well to deliver force feedback to the user during teleoperation.







We conducted a comprehensive evaluation among sate-of-the-art touchless gaming technologies and the feasibility of their adoption into the surgical theater. The final experiment result indicates that all the touchless interfaces occur in the final optimal interface set, thus shows the potential of gaming technologies for being part of the clinical setting in the near future.
