Knowledge Navigator (1987/88)

5 Replies

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.

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 reminiscent of the multitouch interface 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 written and conceived by Hugh Dubberly and Doris Mitsch of Apple Creative Services, and produced by The Kenwood Group in San Francisco. Director: Randy Field. Director of Photography: Bill Zarchy. As a vision statement the films were groundbreaking, as powerful a vision of the future of computing as 2001: A Space Odyssey. It may be useful to note that the video opened with the statement “In the year 2010.” Most viewers missed this indication that the Knowledge Navigator was a visitor from the future and wanted the features now.

The astute bow tie wearing software agent in the video has been the center of quite a few heated discussions in the domain of human-computer interaction. It was criticized as being an unrealistic portrayal of the capacities of any software agent in the foreseeable future, or even in a distant future. Some user interface professionals like Ben Shneiderman of the University of Maryland, College Park have also criticized its use of a human likeness for giving a misleading idea of the nature of any interaction with a computer, present or future.

Compared to recent research in the field of ubiquitous computing and augmented reality interfaces many of the aspects of the Knowledge Navigator seem a bit quaint. For some however this video prototype was and/or still is a source of motivation for their work. They see it as a goal set in a future they might help create one day. To some extent the concept was also used to position the Apple Newton handheld device. Newton was released before the technology was mature however, and proved to be a commercial failure. Eventually, the advent of the Internet and the World Wide Web and several devices marketed by Apple’s competitors would indeed fulfill some of the visions of the Knowledge Navigator.

Steve Jobs introduces the Think Different campaign (1997)

Leave a reply

In the video embedded below, the Apple CEO introduces the company’s 1997 Think Different campaign. A key quote:

[Our new ad campaign] honors those people who have changed the world. Some of them are living, some of them are not. But the ones that aren’t–you know that if they ever used a computer, it would have been a Mac.

And another:

This is a very complicated world. This is a very noisy world, and we’re not going to get a chance…to get people to remember much about us. No company is. And so we have to be really clear on what we want them to know about us.

And this is the famous commercial:

Guy Kawasaki: “The secret to Apple’s Success”

Question: What makes Apple revolutionary?

Guy Kawasaki: if you were to ask people in 1983, you know, what would you like in a personal computer? They would have said, bigger, faster, cheaper, MS-DOS machine, bigger, faster, cheaper Apple II. No one would have described the Macintosh. And so the genius of Steve Jobs is not that he listens to the marketplace, focus groups and marketing research and then he takes that research and he implements it, he does not believe in market research. Market research for Apple Computer is Steve’s left hemisphere is connected to his right hemisphere. That’s the focus group.

And so the lesson of Apple is, you know, you cannot necessarily just listen to what able are saying they need because they are going to define everything they need in terms they already know, bigger, faster, cheaper. The true revolutionary, then surely enchanting company creates a product or service before people can really define the need for that product or service. They anticipated where the market will go as opposed to simply reacting quickly to where the market is already going.

Did Steve Jobs steal everything from Xerox PARC?

It is claimed again and again that in the course of the Macintosh’s development, Apple just resorted to the ideas the research laboratory Xerox PARC had hatched before. Fact or Fiction?

The myth says, Apple CEO Steve Jobs saw Xerox PARC product, such as the GUI, either on a tour or at a trade show. He then used the PARC GUI implementation without permission, to create the Apple Lisa and the original Mac OS / Macintosh GUI.

The myth entwines about a late 1979 visit to Xerox PARC by a group of Apple engineers and executives led by Steve Jobs. Alex Soojung-Kim Pang, author of “Making the Macintosh”, writes:

According to early reports, it was on this visit that Jobs discovered the mouse, windows, icons, and other technologies that had been developed at PARC. These wonders had been locked away at PARC by a staff that didn’t understand the revolutionary potential of what they had created. Jobs, in contrast, was immediately converted to the religion of the graphical user interface, and ordered them copied by Apple, starting down the track that would eventually yield the Lisa and “insanely great” Macintosh. The Apple engineers– that band of brothers, that bunch of pirates– stole the fire of the gods, and gave it to the people.

It’s a good story. Unfortunately, it’s also wrong in almost every way a story can be wrong. There are problems with chronology and timing. The testimony of a number of key figures at Apple suggests that the visit was not the revelation early accounts made it out to be. But the story also carries deeper assumptions about Apple, Xerox PARC, computer science in the late 1970s, and even the nature of invention and innovation that deserve to be examined and challenged.

Let us take a closer look at what happend at Xerox PARC:

Entrance of Xerox PARC in the eighties

In the Untied States, the brand name “Xerox” denotes photocopying just as “Kleenex” stands for tissues or “Scotch tape” for adhesive film. After all, already in 1950, the Xerox Corp. was the world’s first company to actually transfer the “Xerography” invented by the American law student Chester Carlson into a functional product. Carlson received in 1937 a patent for a process that he called “electrophotography.” On 22 October 1938 followed the premiere in practice: With the help of a metal plate was coated with sulfur and a lamp Chester the lettering “10-22-38 Astoria” on a wax paper.

The first photocopy

By the end of the sixties, the Xerox management sensed the threat of Japanese companies catching up on Xerox’s technological advantage. Moreover, the Xerox head worried that the “paperless office” might emerge with the following computer generations, in which the Xerox would no longer have a place. Against this background, the Xerox Palo Alto Research Center (PARC) in California was founded in 1970. John Warnock, former researcher in the Xerox PARC and later one of the two founders of Adobe Systems, remembers: “The atmosphere was electric – there was total intellectual freedom. There was no conventional wisdom; almost every idea was up for challenge and got challenged regularly.”

Larry Tessler, who later took part in developing the Macintosh and the Newton PDA at Apple, also enjoyed the liberties the PARC provided in the seventies: “The management said go create the new world. We don’t understand it. Here are people who have a lot of ideas and tremendous talent, [are] young, energetic.” The problem, however, was that the company management at the East Coast of the USA did not [care a straw for] the PARC’s research results unless they were directly involved with photocopiers.

Within two years, the researchers at the PARC had designed the Alto, which was something like the first personal computer. The Alto did not feature character-oriented graphics, as did all the other computers of that time, but a bit-oriented version instead. A high quality printer could print exactly what the screen displayed.

A mouse. Removable data storage. Networking. A visual user interface. Easy-to-use graphics software. “What You See Is What You Get” (WYSIWYG) printing, with printed documents matching what users saw on screen. E-mail. Alto for the first time combined these and other now-familiar elements in one small computer.

Developed by Xerox as a research system, the Alto marked a radical leap in the evolution of how computers interact with people, leading the way to today’s computers.

By making human-computer communications more intuitive and user friendly, Alto and similar systems opened computing to wide use by non-specialists, including children.

People were able to focus on using the computer as a tool to accomplish a task rather than on learning their computer’s technical details.

However, this marvelous machine was not freely available on the market. Only small numbers were built initially, but by the late 1970s, about 1,000 were in use at various Xerox laboratories, and about another 500 in several universities. Total production was about 2,000 systems.

The revolutionary Alto would have been an expensive personal computer if put on sale commercially. Lead engineer Charles Thacker noted that the first one cost Xerox $12,000. As a product, the price tag might have been $40,000.

Commercial for the Xerox Alto (1972).

This commercial for Xerox’s Alto computer released in 1972 introduced the world to the first desktop computer with a graphical user interface. Named after Xerox PARC’s home city of Palo Alto, California, the computer introduced the world to the window-oriented mouse and keyboard interface we use today. The Alto also had a distinctive portrait screen — an idea that was well before its time.

The video showed how the computer could revolutionize your office life, with email, word processing and reminders all controlled by a cursor. It also shows the protagonist expressing his thoughts and actions out loud, as if in conversation with the Alto (which seems to be nicknamed “Fred”).

Some Apple engineers were already familiar with PARC, its work, or technologies like the mouse. Bill Atkinson had read about Smalltalk as an undergraduate. Some had worked at PARC: Jef Raskin spent time there during a sabbatical year at Stanford, and had a number of friends who were researchers there. Finally, there were even some Apple employees whose had learned about the mouse while working for Douglas Engelbart at SRI in the 1960s and early 1970s, or Tymshare in the later 1970s.

The making of Macintosh – An Interview with The Macintosh Design Team (Byte – Feb, 1984)

Bill Atkinson

Bill Atkinson nearly had his Ph.D. in neurochemistry before he admitted to himself that his real love was computers. He “got a quick E.E.” and started his own company. He was happily minding his own business when his friend ]eff Raskin asked him to come see what was happening at Apple, which was then six months old. Bill wasn’t really interested, but airplane tickets showed up in the mail, so he took a look. What he saw was “several years reaching into the future” of anything he could do where he was. He stayed to write Apple’s Pascal and later became Mr. User Interface for Lisa before he moved over to the Mac team.

 

 

Andy Hertzfeld

Andy Hertzfeld says, “The Apple II changed my life.” The computer people at Berkeley were a little narrow-minded about letting a grad student really get into the computer as Andy wanted to. So he spent nearly all the money he had in the world on an Apple II and had a computer he could control completely. He decided the Apple was more interesting than his classes and began writing programs for magazines. When Apple bought one of Andy’s programs, Steve Jobs offered him a job, which he took when he finished school. He worked on silent-type printers and Apple III demos until a shake-up in his part of the company shook him loose. He looked around and decided to go with Mac.

 

 

Larry Kenyon

Larry Kenyon arrived at Apple from Amdahl with a double degree in psychology and computer science. He was working on Apple III products when the same shake-up that shook Andy loose freed him, too. Andy asked Larry to join the Mac crew because he was one of the few people who understood the arcane art of making the Apple II work with printer peripherals, and anybody who can do that has to be good. No one in the company really believed that Mac was a product when Larry joined the Mac team. It was just a research effort, and there was some risk involved: would you still have your job in a few months?

 

 

Joanna Hoffman

Joanna Hoffman is still on leave from her Ph.D. program in archaeology at the University of Chicago. She has a background in anthropology, physics, and linguistics. She came to Apple because of Mac. After using her computer skills in the field of archaeology for so long, she was tired of looking at the past and turned to the future. She was Mac’s entire marketing department for more than a year. She wants to make Mac a tool that feels natural for international users by making it speak their languages.

 

 

Burrell Carver Smith

Burrell Carver Smith encountered the Homebrew Computer Club in 1975, got hooked on microprocessors, and moved to the Bay Area. Just riding around in a borrowed truck one day, he saw Apple and decided to drop in. The only job Apple had available was in the service department, repairing Apple IIs. He took the job and fixed at least a thousand Apple II boards and got involved in other projects before Jeff Raskin and Bill Atkinson recruited him for Mac. He talked the Lisa engineers out of some chips and stuff and got a prototype running over Christmas 1979. He was the first full-time Mac person after Jeff Raskin.

 

 

Chris Espinosa

Chris Espinosa says, There was no life before Apple.” At 13 years old he could be found cruising up and down the bus line in his home town, spending a few hours at each Byte Shop on the line until the owner threw him out. He discovered the way to keep from getting thrown out was to write demo programs for the machines, so he wrote for whatever was lying around: ”Altairs, IMSAIs, or this weird new machine called Apple I. His mom worried when he was offered a ride to the Homebrew Computer Club meeting with two scruffy characters named Jobs and Wozniak, but she gave in, and the rest is history. Chris spent a Christmas vacation debugging Apple’s BASIC in exchange for a whole row of 4K-byte RAM chips, which he thought was a pretty good deal. He worked part-time during college writing BASIC programs and reference manuals and signed on full-time when he graduated. He likes being in on the design process: ”If the machine is designed right in the first place, you don’t have to write a lot about it.”

 

 

Jerry Manock

Jerrold C. Manock was a freelance product-design consultant with a Stanford education who finally joined Apple when he saw that three-quarters of his billing was to Apple anyway. He worked on the Apple II, the Disk II, the III, and Lisa before designing Mac. In Macintosh, he says, “The outside matches the inside in elegant simplicity.”

 

 

 

 

Bruce Horn grew up at Xerox PARC, much the same way Chris grew up at Apple, and later attended Stanford. Bruce started working at Xerox when he was 14 years old: he was one of the kids Xerox brought in to test Smalltalk. Turns out he was brighter than most and became a systems wizard who actually implemented Smalltalk on a variety of different processors. Bruce is all of 23 years old now, but he spent seven years at Xerox PARC and brought Apple that perspective.
