The Knowledge Navigator is a concept described by former Apple Computer CEO John Sculley in his 1987 book, ''Odyssey''. It describes a device that can access a large networked database of hypertext information, and use software agents to assist searching for information. ==Videos== Apple produced several concept videos showcasing the idea. All of them featured a tablet style computer with numerous advanced capabilities, including an excellent text-to-speech system with no hint of "computerese", a gesture based interface resembling the multi-touch interface later used on the iPhone and an equally powerful speech understanding system, allowing the user to converse with the system via an animated "butler" as the software agent. In one vignette a university professor returns home and turns on his computer, in the form of a tablet the size of a large-format book. The agent is a bow-tie wearing butler who appears on the screen and informs him that he has several calls waiting. He ignores most of these, from his mother, and instead uses the system to compile data for a talk on deforestation in the Amazon Rainforest. While he is doing this, the computer informs him that a colleague is calling, and they then exchange data through their machines while holding a video based conversation. In another such video, a young student uses a smaller handheld version of the system to prompt him while he gives a class presentation on volcanoes, eventually sending a movie of an exploding volcano to the video "blackboard". In a final installment a user scans in a newspaper by placing it on the screen of the full-sized version, and then has it help him learn to read by listening to him read the scanned results, and prompting when he pauses. The videos were funded and sponsored by Bud Colligan, Director of Apple's higher education marketing group, written and creatively developed by Hugh Dubberly and Doris Mitsch of Apple Creative Services, with technical and conceptual input from Mike Liebhold of Apple's Advanced Technologies Group and advice from Alan Kay, then an Apple Fellow. The videos were produced by The Kenwood Group in San Francisco and directed by Randy Field. The director of photography was Bill Zarchy. The post-production mix was done by Gary Clayton at Russian Hill Recording for The Kenwood Group. The product industrial design was created by Gavin Ivester and Adam Grosser of Apple design. The Knowledge Navigator video premiered in 1987 at Educom, the leading higher education conference, in a keynote by John Sculley, with demos of multimedia, hypertext and interactive learning directed by Bud Colligan. The music featured in this video is Georg Anton Benda 's Harpsichord Concerto in C. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「knowledge navigator」の詳細全文を読む スポンサード リンク
