Abstract

"This thesis provides an insight into the design and development of a highly effective, low-cost motion tracking system comprised of off-the-shelf (OTS) hardware for virtual reality applications. Present-day motion tracking systems usually have a high cost associated with them. A capable yet affordable OTS motion tracking system is a key enabler to make motion controlled virtual reality an accessible and ubiquitous technology.

The motion tracking system developed in this study is used in conjunction with virtual reality software towards simple and natural human-computer interface solutions. It is developed with the budget of $1,000 per system. The cost includes 2 cameras each fitted with an infrared band-pass filter and several rigid body targets used to track the objects. Active markers are used because of the low cost in developing the system. The developed software supports interfaces for various types of cameras giving the user the ability to choose the camera based on his budget. The system is developed to work on a low-end workstation with all the processing done at the software level. It is designed to work at 60 frames per second with latency less than 30 ms and the ability to track at least 5 objects with 6 degrees of freedom. For the Firefly MV cameras used in this study, the average accuracy of the system measured is 0.649mm.

The developed system is interoperable with various simulation toolkits including WorldViz Vizard toolkit and Siemens NX CAD package. Various simulation samples have been created to demonstrate the functionalities of the system with multiple objects in motion"--Abstract, page iii.
