Virtual Object Position Manipulation Using ARToolKit

Virtual Chopsticks: Object Manipulation using Multiple Exact Interactions

A technique is proposed for object manipulation with a virtual tool using multiple exact interactions. Exact test is introduced that uses real-time collision detection for both hand-and-tool and tool-and-object interactions. Chopsticks are adopted for one of the trials of our technique; although they have a very simple shape, they do have multiple functions. Here, a virtual object is manipulate...

Student projects using ARToolKit

In this paper we would like to describe three student projects developed at the University of Applied Science at Hagenberg (Media Technology and Design) using ARToolKit. All projects were implemented by students during their semester projects or during their master thesis. MusicAR is the first application presented in this paper. It describes the master thesis of B. Hauser and shows a nice musi...

Cooperative Object Manipulation in Immersive Virtual Environments

Interactive Multi-object Tracking for Virtual Object Manipulation

We present an interactive system to manipulate a virtual object by tracking multiple hands in 3D space using a Kinect device. The system segments hand shapes from a captured 3D scene by using depth information and active contours. A hand shape is recognized by a trained naive Bayes classifier, whether it belongs to a palm, a pointing hand form or both hands with simple occlusion. A plane is app...

Using ARToolKit for 3D Hand Position Tracking in Mobile Outdoor Environments

Introduction This poster presents how we have used the ARToolKit to develop a cheap and low cost 3DOF (degrees of freedom) hand tracker, allowing us to use a video camera (see figure 2) mounted on the head to track the motion of the hands of the user (see figure 1) as real world X, Y, Z values. This tracker is most useful when working in mobile outdoor environments, as traditional tracking tech...
