Multimedia languages for teleaction objects

A teleaction object (TAO) is a multimedia object with associated hypergraph structure and knowledge structure. The user can create and modify the private knowledge of a TAO so that the TAO will react automatically to certain events. The hypergraph structure supports the effective presentation and efficient communication of multimedia information. TAOs are extremely valuable since they greatly improve the selective access and presentation of relevant multimedia information. Following the ideas of Chang (1996), the authors show how visual languages can be extended to multimedia languages for production of TAOs.
