Development of AR System Using Hand Gesture

Taiji TSUCHIYA*, Kazuhiko TAKAHASHI**

(Received May, 22, 2009)

To achieve a wearable computing system without taking input devices, such as mouse and keyboard, this paper presents an augmented reality (AR) system utilizing hand gestures to control system and investigates its characteristics. The AR environment is composed by the simple technique that synthesizes a virtual object with the input image captured from a small CCD camera on the image plane. A gyro sensor mounted on HMD measures a user’s head movement information, and the processing method that controls the virtual object to make the same behavior of the real world scenery by using the head movement information is proposed. The control method of manipulating virtual objects by hand gestures is proposed and the experimental results of hand gesture recognition confirm feasibility and usefulness of the proposed method. Assuming a task of WEB browsing, human subjects evaluate the proposed AR system. Experimental results indicate that the proposed system is not required to carry any input device and the interface is hard to use but has entertainment characteristics.
