In this work we present how Augmented Reality (AR) can be used to create an intimate integration of process data with the workspace of an industrial CNC (computer numerical control) machine. 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.

We present a novel autostereoscopic optical see-through system for Augmented Reality (AR). 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.

We have identified the need for, and started development of, a new tool we call an interaction table. 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.
