PhD (Computer Engineering)
Dr. Shahzad Rasool joined the Research Center for Modeling and Simulation (RCMS), National University of Science and Technology (NUST) as an Assistant Professor at in August 2016. Previously, he worked as a Research Fellow at the Immersive Mathematics Lab of Fraunhofer IDM @ NTU, Singapore from 2014 to 2016. He received his Ph.D. from Nanyang Technological University (NTU), Singapore in 2014, M.Sc. degree in Communication Engineering from Technische Universität München (TUM), Germany in 2009 and B.Sc. in Electrical Engineering from University of Engineering and Technology (UET), Taxila, Pakistan in 2006. In 2008, he worked as a research intern at DOCOMO Communications Laboratories Europe, Munich. His research interests include haptics, virtual reality and HCI.
Haptic interaction is typically based on detecting collisions of the haptic interaction point with physical models of the virtual objects comprising polygon meshes, point sets, or procedural models topologically collocated with the geometric models of the object in the modeling space. Traditional polygon-based modelling representation yields large sized files and time consuming visual rendering to achieve photorealistic quality. This deficiency could be overcome by employing image-based representations. Based on the paradigm ‘what we see is what we touch’, tangible images present a set of techniques for making two dimensional images tangible. Algorithms for haptic geometry rendering, haptic rendering of surface texture and physical properties are devised.
Interaction with hybrid scenes composed of 3D models and 2D images is also explored. Visible 3D models are used to simulate editable parts of scene while low resolution invisible 3D models are used as haptic containers to augment the visual interaction experience. These haptic models have simplified geometry and are additionally capable of representing non-visual force effects such as wind, flow, magnetism, etc.
Image-based virtual arthroscopy training
Virtual simulation of minimally invasive arthroscopic surgery procedures including triangulation of the surgical tools and treating meniscus injury. A set of training exercises for learning basic skills required for such minimally invasive surgery are simulated. A panoramic image of the knee cavity is constructed from representative frames of a real arthroscopic surgery video. The oblique-viewing camera is modelled to display the respective part of the image based on the manipulation of a haptic device. A second haptic device controls the arthroscopic tools used for various surgical procedures. 3D objects defined by mathematical functions are superimposed to the image to simulate deformable and modifiable parts of the scene.
Tangible video communication
In this research we explore methods of making audiovisual communication across the network more immersive. Different interaction devices are used by the local user to control a remote haptic devices operated by the remote user. The aim of the project is to minimize the amount of information exchanged and reduce the network transmission delay so that seamless interaction can be achieved. Executed concurrently with any video chat application, immersive tangible experience is produced.
