Interface design for an inexpensive hands-free collaborative videoconferencing system

Abstract

In this paper an interaction framework for AR enhanced video conferencing is presented. The goal is to provide a cheap and portable system based on a combination of commodity Kinect cameras and regular computer screens. These conditions necessitate the use of contact free interaction methods. The interaction framework presented in this paper is specifically suited for remotely presenting, sharing and annotating visual data such as images, presentation slides and 3D objects. In the proposed system all data is represented by freely manipulable 3D objects which are augmented into the camera views. These representations are integrated into a differentiated ownership scheme, allowing for operations such as spatially managed data sharing. The suitability of different interaction paradigms with regards to this usage scenario is examined. Furthermore, occlusion and collision management between virtual objects and real obstacles is enabled by integrating basic models of the environment.

Developing an AR Lecture Recording System with Direct Manipulation of Virtual Slides by Physical Objects

“…Some studies use AR and 2D CG technologies and develop expressive and graphical user interactions in various situations such as educational support [9], video conference [10], and collaborative work [11]. User-friendly methods, such as a direct manipulation interface, for controlling visual effects based on gestures and postures of a presenter [12] or simple teaching motions [13] have been proposed.…”

DigiLog Space Generator for Tele-Collaboration in an Augmented Reality Environment

“…In 2.5-D display environment, users can collaborate in a limited 3-D environment using a curved screen that has been installed in a fixed location [4]. On the other hand, multiple cameras or depth cameras are used in a 3-D display environment [5][6][7], but tele camera or screen. So we ne perfect 3-D interaction.…”
