A Virtual Environment Training System for Haptic Laparoscopic Surgery

Work from the collaboration between Dr Fengda Zhao  (Yanshan University, Qinhuangdao, P.R.China) and Dr Yinghui Zhang (Division of Computing, School of Science and Technology, University of Northampton, UK) is to be presented at  16th International Conference of Automation and Computing, University of Birmingham, Birmingham, UK, 11 September 2010.The work looks at developing a prototype haptics-based surgical training system


Most of the existing laparoscopic simulations which use simple objects are only for the purpose of the training of laparoscopic surgical skills. We have designed and developed an early prototype of a laparoscopic simulation system in which almost all of the soft tissue organs are modeled as deformable models which can be manipulated using a laparoscopic instrument with haptic feedback. Physics-based modeling is applied to realize collision detection, force rendering and elasticity deformation. A new mechanism to analyze and evaluate the injuries to the soft issues is introduced. Preliminary experimental results show that the simulator can meet the requirement of 1 kHz haptic loop update rate under complex virtual scene.


This collaboration was supported by a Leverhulme Fellowship .

Social Analysis of Publications

The Computing staff's network of co-authors, at the University of Northampton, based on the University's  research repository NECTAR - http://nectar.northampton.ac.uk/view/divisions/SSTCT.html on 12th November 2016. The data goes back to 2010.




The data was analysed using the software VOSviewer - http://www.vosviewer.com/ free software for visualising networks. Differences in colours represents, the clusters of publications with those authors picked out by the software. The relative size of the circles is the relative number of publications listed; so for the two biggest circles/hubs it relates to 55 and 34 publications in this time period. Some relatively new authors, to the University but not to research, explains some of the 'islands' and the number of publications within it - it only reflects publications whilst at the University of Northampton.

To dig a little deeper, going to  look at the two biggest 'hubs' through their NECTAR records, so potentially going …

Computer lecturer’s research helps improve the next generation of technology

Taken from: http://www.northampton.ac.uk/news/computer-lecturers-research-helps-improve-the-next-generation-of-technology/ A computing lecturer at the University of Northampton, who is researching into how the efficiency of our everyday devices, such as mobile phones, can be improved, has been awarded the best paper at two recent conferences. Dr Michael Opoku Agyeman has written several journal papers focusing on how the next generation of technology can meet the ever increasing demands from consumers. He was invited to present his work at the 19th Euromicro Conference on Digital System Design in Cyprus and the Institute of Electrical and Electronics Engineers’ 14th International Conference in Paris. Part of his research concentrates on whether several processing elements can be incorporated on a single chip, known as System-On-Chip, to improve the efficiency and speed of the computing systems that we use every day, from mobile phones to video-game consoles and even medical equipment…
