Ghost Hunter: A Handheld Augmented Reality Game System with Dynamic Environment

Abstract

Abstract. The progress of handheld devices has encouraged many researchers to make efforts to use handheld devices as an augmented reality platform. However, one of the important problems is a lack of immersion and reality due to small display. To overcome this problem, we introduce dynamic environment which consists of some movable structures and their controller that enable changes of virtual world to affect the real world. It has an effect on expanding the user's view limited by the small display of the handheld device. We have also developed the game content, 'Ghost Hunter', which is suitable for this platform.

Vision-Based Markerless Gaming Interface

“…Examples of videogames built on top of optical marker trackers have been growing steadily in recent years. Cho et al [2] described an augmented reality shoot-em-up game in which players aim at virtual opponents rendered on a game board filled with optical markers. Oda et al [17] developed a racing game where users steer their virtual cars using controllers stuck with markers monitored with cameras.…”

“…Despite many advances have been recently reached in the field of human gesture, motion and behaviour understanding [10,20,11], engineers have been mostly focusing on marker-based tracking systems for humancomputer interaction applications. The gaming industry is recently showing a deep interest in vision based interfaces, with many proof of concepts developed so far [7,21,2,17]. As a matter of fact visual markers can be reliably tracked [5] at low computational costs, nonetheless game boards or game controllers must be instrumented with them.…”

Fear Inducer: A Mixed Reality Audio Experience

“…Most of the mixed reality systems however are focussed on visual effects [3] [4], but audio has much potential as well. In this project the use of mixed reality in audio is investigated through the design of a product for a specific target group.…”
