A Single Camera Based Natural User Interface Engine Development
Song We · 2015
Natural user interfaces(NUI)are a novel way to provide human computer interaction(HCI)with natural and intuitive operation interfaces.This paper designs a single camera based NUI architecture using an inexpensive web camera as a means of input device for NUI applications.By integrating the CUDA toolkit and the DirectX software development kit(SDK),a real-time NUI engine system is developed.The system captures video via the web camera,implements real-time image processing using graphic processing unit(GPU)programming,and presents the NUI applications using the DirectX SDK.To verify the efficacy of the proposed NUI engine,this paper utilizes it in the development of several touch-less operation applications and mixed reality games.The experienmantal results confirm that the engine realizes real-time and intuitive interactive operations.
