DEVELOPMENT OF AN APPLICATION WITH 3D INTERACTION - KINECTCITY

Abstract

Human-computer interaction is a discipline intended to examine and define safe, intuitive and flexible means for human users to issue instructions to computers, and for computers to inform about outcomes. 3D interaction is a special kind of interaction where the position (in 3D space) of objects involved in interaction is of great importance. Traditionally, the user issues his/her requests through a sequence of commands on input devices, such as mouse or keyboard, and the computer displays the results on an output device, such as monitor. Recent advances in technology resulted in wide availability of inexpensive devices that can detect and track human body in 3D space. This opens a possibility to establish 3D interaction with computers, even in casual conditions. This paper presents the development of a 3D application KinectCity, in which the user establishes interaction with body gestures and spoken commands. The application was developed in Unity3D. Kinect was used for body detection and tracking. in presence of adequate hardware, the application can present stereoscopic viewing, which significantly increases the 3D interaction experience with the virutal world.
