Ho Man Colman Leung

I am a first-year PhD student in Computer Science at Dartmouth College, working with Prof. Xia Zhou. Before that, I earned my BSc and MPhil in Computer Science at the Chinese University of Hong Kong under the supervision of Prof. Pheng-ann Heng and Prof. Chi-wing Fu.

My work focuses on making computers more accessible to users by understanding human behaviors from the computer's perspective and providing a tailor-made experience to users. This is done by combining sensing technology, ubiquitous computing, and aesthetics into novel interactive systems.

Research Associate

Department of Computer Science and Engineering, The Chinese University of Hong Kong

  • Developing a robust multi-camera multi-object 6DoF real-time tracking system for precise tangible interactions used in medical simulators.
  • Improved tracking performance by parallelizing the algorithms, accelerating with CUDA, and overlapping the operations with pipelining.
  • Currently achieved >60 frame rate for tracking two small objects accurately within a 60 x 60 cm2 area.
2012 - 2015

Software Engineer

Dracaena Life Technologies Co., Ltd., Hong Kong

    • Designed the system architecture and developed an anatomy visualization tool for educational purposes, featuring stereoscopic 3D visualization to create an immersive learning environment and mid-air gestures using Leap Motion for interactive navigation.
    • Deployed in School of Nursing of The Hong Kong Polytechnic University. User Study showed positive feedback from users.
  • Virtual Acupuncture

    • Developed a Traditional Chinese Acupuncture Simulation System based on the Interventional Sonography Training System.
    • Modified the original needle to measure the needle's rotation using rotary encoders and arduino microcontrollers.
  • Interventional Sonography Training System

    • Implemented new features including stereoscopic rendering and head tracking 3D simulation using Kinect.
