Document Summary
Threshold objects in the real world are like a tools that is used to effect work on an external object. Interaction in the digital medium there are actual interface devices that afford interaction with abstract process and data, such as a mouse, a game controller. With virtual, abstract materials, objects and data interaction is afforded in many cases by a virtual tool, device or object. In digital video editing, the editor can (cid:498)scrub(cid:499) across the stream of the video file using the time position indicator in red. There is no actual (cid:498)film(cid:499) it is a just data. )n the tape editing systems of previous technology, a (cid:498)pot(cid:499) was used to control advance the stream or reverse the stream. This is done with a mouse or with a the servo motors in the tape machine, to scrub across the physical tape. By using threshold objects, a tele-operator can control other systems.
