Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: This paper proposes a system that controls an image shown on a screen through hand information extracted from a depth camera. The proposed method extracts the hand region from the distance information obtained from the depth camera, and employs outline extraction and convex hull to locate the fingertips. An image output on a screen was controlled by the velocity of the fingertip information using current and previous frames, and an application program was written to verify the level of control
