Exploring Technical and Behavioral Aspects for Public Motion Controlled Applications’ Development Using 3D TOF Camera

Abstract

Context: Remarkable advances in multimedia games can be seen during recent years. In this thesis a novel way of playing games, merely using human body parts, is under consideration just like XBOX Natal concept [2]. To implement this idea, a newly made 3D Time-Of-Flight (TOF) camera is used to capture the motions i.e. gestures and postures of moving objects. Objective: In this thesis two major research questions are addressed. One is to find out the possible usages and limitations of three dimensional (3D) motion controlled interfaces for Public Interactive Application (PIAs). Second one more technological question is to find out possible and feasible solutions and programming techniques to capture motion using 3D TOF camera. Method: Qualitative research method along with Contextual Inquiry is used to gather and analyze data. Literature study, interviews and some explorations on relevant technology blogs (and forums) were made. Some inspirations were taken from Grounded theory method to analyze collected data. Results: This thesis explores possible usages of TOF camera to develop motion controlled PIAs along with limitations with respect to the potential users. A detailed solution for 3D motion capturing is suggested, which consists of the Visual C++.NET, Win32 Application and OpenCV libraries synchronized by EmguCV wrapper. Conclusion: This report provides a detailed study about the possibilities and limitations of using motion controlled interfaces in public areas. Valuable ideas providing extensive usage and future fertility of this nascent technology have also been described. Findings in this report can provide constructive principles for development of public interactive applications.
