Dr. Gerard Lacey

Associate Professor (Computer Science)

Dr. Lacey has an international research track record using sensors and machine learning to embed intelligence into everyday devices thereby creating new types of human-machine interaction. He has 87 publications including journals, conferences, patents, book chapters, and co-edited books. The majority of this research has been in the healthcare domain with technical contributions in Image Processing, Robotics and Human-Computer Interaction. Dr Lacey has won awards for innovation from Enterprise Ireland (2010) and Trinity College (2011) for various commercial ventures. In 2000 Dr. Lacey founded the TCD spin-off Haptica Ltd, which developed Augmented Reality surgical training products to hospitals and universities around the world. In 2010 he cofounded SureWash which sells hand hygiene training and assessment systems for hospitals and food service. His main research area is sensor driven human-machine interaction. The best know output of this research has been a novel robotic walking frame for the elderly. This research won several best paper awards and was featured on Tomorrows World 1999 and was the subject of a New Scientist article 1999. His main research topics are Computer Vision, Augmented Reality, Robotics and Decision Making in Uncertainty. In his academic carrier he has managed international EU research Projects (3), Enterprise Ireland Projects (2). In 1998-2000 he was leader of the Computer Vision and Robotics Research Group which comprised Post Docs (3), PhD Students (5), MSc Students (7) and visiting professors. His has been a reviewer for Enterprise Ireland 1999-2002, on the scientific review panel for SIRS, IROS, IMVIP, EAAI, RESNA, and reviewed papers for IEEE Neural Systems and Rehabilitation Engineering, Robotics and Autonomous Systems, and the International Journal of Robotics Research. He has been a visiting researcher at the Massachusetts Institute of Technology (MIT) Field and Space Robotics Lab (1999) and the University of Edinburgh, Dept of AI (1995).

My key research areas are Augmented Reality(AR) for healthcare applications, mobile service robots, gesture recognition and serious games. Augmented Reality for healthcare applications: This research is focused on analysis the images from endoscopes (Endoview) and augmenting these images with additional information to assist in clinical decision making or skills assessment. The main themes of the research are object recognition and tracking and accurate rendering of graphical overlays. This work also covers studying the human factors issues involved. Mobile Service Robotics: this work focuses on augmenting existing devices with advanced robotics technology to make these devices smarter. These devices typically have shared control with humans operators and therefore the relationship to the human is a critical element of the control interface. Examples include Robot Mobility Aids for the frail blind (PAM-AID), Aircraft ground collision avoidance (WingWatch). Gesture Recognition: The recognition of fast bimanual hand gestures, using 2D and 3D cameras, is an important interface mechanism for hands-busy, eyes-busy tasks. It is also important for developing tools for objective training and assessment of the many basic clinical skills in healthcare such as hand hygiene (SureWash), surgical skills (ProMIS) and other skills that are assessed via Objective Structured Clinical Exams (OSCEs). Serious games: Games techniques and structures are often useful when developing training and assessment tools for healthcare skills. These have been applied in Infection Control (Handy MD) and hand hygiene (surewash).
