This paper describes the work-in-progress of an online multimedia tool employing the sense of touch in exploring and learning sculpting techniques to be used over the Internet. Many game applications use haptic devices as a control mechanism, yet little has been documented on the use of this controlling procedure in an educational setting. The internet based instructional device presented here has a single modeling tool accessed by a customised interface designed with widely accessible software (Macromedia Director MX™). This will be extended to a small suite of modeling tools, in progress at this time. It makes use of a simple force-feedback joystick to control a spherical tool which makes changes to the surface of a 3D model represented onscreen. It is proposed that by using this device with Flash Web Server and the Internet, the system is able to support a collaborative environment encouraging interaction between student and tutor. It is hoped this system will become a research and development tool in online education.
