AR allows us to combine interactive computer graphics with real objects in a physical environment - in this case, the workspace of an industrial lathe. ASTOR is an autostereoscopic

It uses a transparent holographic optical element (HOE) to separate the views produced by two, or more, digital projectors. It is a minimally intrusive AR system that does not require the user to wear special glasses or any other equipment, since the user will see different images depending on the point of view. The HOE itself is a thin glass plate or plastic film that can easily be incorporated into other surfaces, such as a window. The technology offers great flexibility, allowing the projectors to be placed where they are the least intrusive. ASTOR's capability of sporadic AR visualization is currently ideal for smaller physical workspaces, such as our prototype setup in an industrial environment.

In this paper the experiences with the first prototype are described. The interaction table presents a computer-generated, autostereoscopic, three-dimensional image that can be viewed and interacted with.

Based on models and visualisation technologies, the appearance and behaviour of a technical system can be studied, simulated and viewed for different purposes, in different disciplines, and at different detailing levels. It forms the base for human communication

Some issues with large format displays of this kind are discussed, as well as their image quality, especially the contrast. The demands of some engineering applications are also described.

AR allows us to combine interactive computer graphics with real objects in a physical environment -in this case, the workspace of an industrial lathe. ASTOR is an autostereoscopic optical see-through spatial AR system, which provides real-time 3D visual feedback without the need for user-worn equipment, such as head-mounted displays or sensors for tracking. The use of a transparent holographic optical element, overlaid onto the safety glass, allows the system to simultaneously provide bright imagery and clear visibility of the tool and workpiece. The system makes it possible to enhance visibility of occluded tools as well as to visualize real-time data from the process in the 3D space. The graphics are geometrically registered with the workspace and provide an intuitive representation of the process, amplifying the user's understanding and simplifying machine operation.
