Douglas Engelbart: Augmenting Human Intellect and Bootstrapping

The Roaring Twenties witnessed fast economic growth until the Wall Street Crash of 1929. Before finally bottoming out in 1932, the Dow Jones Industrial Average would lose 89% of its value.1 Growing up during this time period meant a more simplified view of one’s needs. This led to a definitive moment that occurred in Douglas Engelbart’s life when he was just 25 years old. During the December of 1950, after taking stock of his current life, with his job at the National Advisory Committee on Aeronautics, and figuring out that he had achieved the goals he had set forth as a kid growing up during the Great Depression to “get an education, get a steady job, get married”, he discovered that he “no longer had any goals.”2 On a drive through Northern California, being an electrical engineer at Ames Research, he actually calculated that he had roughly 5.5 million more minutes to work during his life. He had to figure out what to do with this precious time.
With no particular designs on getting rich or changing careers, he though about saving the world. And while pondering about how to fulfill this need after several months he came up with the following insight:
FLASH-1: The difficulty of mankind’s problems was increasing at a greater rate than our ability to cope. (We are in trouble.)
FLASH-2: Boosting mankind’s ability to deal with complex, urgent problems would be an attractive candidate as an arena in which a young person might try to “make the most difference.” (Yes, but there’s that question of what does the young electrical engineer do about it? Retread for a role as educator, research psychologist, legislator...? Is there any handle there that an electrical engineer could...?
FLASH-3: Aha - graphic vision surges forth of me sitting at a large CRT console, working in ways that are rapidly evolving in front of my eyes (beginning from memories of the radar-screen consoles I used to service.)3
After working through some details regarding the implementation of such a device where a “general-purpose, computer-powered information environment”4 would assist with network-based collaborations between colleagues, he dubbed this new route in his career “augmenting the human intellect.” However, it wouldn’t be so easy to get others to share in his vision or to provide funding for this lofty endeavor.
Within the context of 1950’s technological ability, this vision still seemed unattainable to others in his department or in the business world. Afterall, the leading edge in technology was the IBM 704, capable of executing up to 40,000 instructions per second. So instead of developing the idea of augmenting human intellect for his PhD, he wrote his dissertation on bi-stable gaseous plasma digital devices. After graduating, he tried to find a more “congenial” environment for his augmentation work, but found out that he had to subsume his intentions even at the Stanford Research Institute where he began working in October 1957.
When he was finally able to work on augmentation in 1959 after receiving funding from the Air Force’s Office of Scientific Research, it was difficult to get intellectual backing for his project because he had to place his augmentation research squarely in the realm of other’s disciplines in order for them to be responsive to his message. In general, his augmentation environment was written off “as just another information-retrieval system.” So, in order to be taken more seriously, he decided to create a manifesto, taking him almost two years to write.
“Augmenting the Human Intellect: A Conceptual Framework” was finished in 1962. Engelbart believed technology could augment human intellect by developing “an integrated hierarchy of cooperative mancomputer process capabilities.” This would “step-up” the mental abilities of a person level by level to be able to handle more complex thought processes. He also explains that, “We refer to a way of life in an integrated domain where hunches, cut-and-try, intangibles, and the human ‘feel for a situation’ usefully coexist with powerful concepts, streamlined technologies and notation, sophisticated methods, and high-powered electronic aids.”5
In his paper, Engelbart writes that two people during the previous two decades had “speculated upon the possibilities of close manmachine cooperation.” Those influences were Vannevar Bush and J.C.R. Licklider. Bush coined the term Memex to describe a system where items were categorized by associative indexing and then searched for using a specialized workstation. Licklider (1960) defined a concept called “man-computer symbiosis”, a system whereby humans and computers work in conjunction to “think as no human brain has ever thought and process data in a way not approached by the information-handling machines we know today.”6 Engelbart also placed his aspirations within the context of work being done by Vazsonyi, Morse, Teager, Culler and Huff. One amongst his list would prove to be a powerful supporter and ally.
While Engelbart attempted to figure out how human beings have so far evolved to deal with complex situations, he tried to receive funding from various sources. His proposal for creating an “interdisciplinary Knowledge Augmentation Laboratory that could pursue the technology of human augmentation as quickly as possible”7 finally came across the desk of J.C.R. Licklider at ARPA.
By 1963, Engelbart had funding. Later he would explain, “Lick was the first person to believe in me. And he was the first person to stick his neck out and give me a chance. In fact, if he hadn’t done that, if he hadn’t stuck his neck out and given me money, I don’t think anybody ever would have done so. That was why I trusted him. Lick was like my big brother.”8
While working towards augmenting human intellect, he would invent the mouse, work on “hypertext systems as part of the NLS” (oNLine System), and work towards his “vision for a personal workstation that can legitimately be thought of as one of the sources of ideas for the personal computer.”9
The NLS was first publicly demonstrated at the 1968 Fall Joint Computer Conference during a 90-minute multimedia presentation where Engelbart debuted the mouse, hypermedia, and on-screen video teleconferencing. In 1989 he founded the Bootstrap Institute, with its main focus being to create high-performance organizations that include “pro-active participation from stakeholders” in all realms of influence including government, industry, and society.
Engelbart, with his evolving pursuits, realizes that with the quick development of technology coming to surpass the development of human intellect, certain adjustments must be made. As the sophistication of technology increases, society has to continually revise it’s methods of information appropriation to accommodate these changes. Engelbart (1998) has conceded this need for modification in the following quote:
Real social danger today is that the technology is erupting and moving so much faster than it ever ever ever has in all of our historical experience ... [It’s] time to start adapting society to this revolution in the technology. There’s a lot of potential dangers ahead if we don’t adapt it successfully.10
Stated more succinctly as the Law of Disruption, Downes and Mui in Unleashing the Killer App (2000) write that “[s]ocial, political and economic systems change incrementally, but technology changes exponentially.”11
The bootstrapping approach is being developed upon currently by the Doug Engelbart Institute. Additionally, in 2005 Engelbart received funding for the HyperScope project from the National Science Foundation. Once again, we find that time often leads to newer technology that is more easily capable of achieving previously stated goals. In this case, Hyperscope uses Ajax and DHTML to recreate the abilities of the NLS and the renamed software Augment that can link within and across documents in order to “engage a wider community in a dialogue of collaborative software and services.”12
Augmenting human intellect as a theory and aspiration has itself been further augmented to suggest that all facets of society must come together and work towards a common goal. As coined by Engelbart, organizations can improve the process they use for improvement, thereby iteratively compounding the effect. As a goal for HCI, iterative progress towards making information more usable, intuitive, and effective would be the perfect compliment to Engelbart’s dream. It seems that intellect’s final compatriots would be responsibility and compassion, and if this has not yet been addressed, perhaps it will be in the next iteration.

Hypertext – Links from the past


Introduction

Clickable text is so ubiquitous in everyday life that the concept of ‘linking’ to content is second nature. Hypertext has shaped the way that we think of the organization of information and the way we think of the information itself. Hypertext has been instrumental in the development of the individual nature of the personal computer, and the integration of massive amounts of people.

Definition

Hypertext is “ … text, distributed to a set of discrete sections, with referential links in between.”[ Müller-Prove] The most typical manifestation of hypertext is through World Wide Web, which
typically presents hypertext ‘links’ as underlined, blue text in order to separate it from the rest of the content on a web-page. When a person selects a link, they are re-directed to the information at the ‘target’ of the link.

Hypertext is essentially an expansion on the concept of reference. Precursors of hypertext include: Table of Contents, Footnotes, and Bibliographies. In a Table of Contents, one needs only find the page number associated with the chapter that you are interested in and turn to that page in order to access the content. Footnotes allow the author to refer to items that support their argument without breaking the flow of the document. Bibliographies ‘links’ to other
documents referenced in the creation of a document.

Bush and the Memex

Hypertext was conceived of very early. The ‘backbone of the web’ began in the mind of a man
named Vannevar Bush. Bush was the Director of the Office of Scientific Research and
Development which coordinate scientific research during World War II. In an article entitled “As
We May Think” published in the Atlantic Monthly in July 1945, Bush outlined his ideas for the future of the organization of knowledge:

“A special button transfers him immediately to the first page of the index. Any given book of his library can thus be called up and consulted with far greater facility than if it were taken from a shelf. As he has several projection positions, he can leave oneitem in position while he calls up another. He can add marginal notes and comments, taking advantage of one possible type of dry photography, and it could even be arranged so that he can do this by a stylus scheme, such as is now employed in the telautograph seen in railroad waiting rooms, just as though he had the physical page before him.” [Bush]

Bush envisioned the his information device as an item shaped like a desk with screens that the user can read from and some controls, such as a keyboard and sets of buttons and levers. This device would be “… a device in which an individual stores all his books, records and communications and which is mechanized so that it may be consulted with exceeding speed and flexibility.” [Bush] Bush saw into the future and predicted, to some extent, the personal computer.

Engelbart’s Expansion

The memex was never created. Douglas Engelbart took the concept of Bush’s memex and took
steps toward making it a reality [Simpson]. In his 1962 paper, “Augmenting Human Intellect: A Conceptual
Framework” Engelbart described a system that allowed a
professional to navigate cross-linked data [Engelbart]. Engelbart’s ideas were somewhat difficult for the rest of the
scientific community to stomach because computers were gigantic number-crunching
machines that
performed relatively simple number-related tasks.

On December 9, 1968, Douglas Engelbart made a bold move.
In a session of the Fall Joint Computer Conference held at the Convention Center in San Francisco, Engelbart presented was has been described as “The mother of all demos” to an
audience of 1000 computer professionals. In the demo Engelbart presented the Online System (NLS) for the first time. NLS was full of ‘firsts’, including the mouse, hypermedia, computer-aided meetings, and document version control system. [Engelbart, Christina]


Nelson and Project Xanadu

The word ‘hypertext’ was coined by Ted Nelson and was first published in a paper for th
e Association for Computing Machinery (ACM) in 1965 [Nelson 1]. Nelson has also been credited with the first use of the term ‘hypermedia’. While Nelson had also been greatly influenced by
Bush’s “As We May Think” paper, his approach was vastly different from Engelbart’s. Where Engelbart and Bush approached the problem of knowledge organization from a practical, mechanical perspective, Nelson came from a background of philosophy and sociology.

In 1960, Ted Nelson founded Project Xanadu [Xanadu] , which was the first ever hypertext project. In ‘Weaving the Web’, Tim Berners-Lee and Mark Fischetti stated [Berners-Lee 1]

“Ted Nelson, a professional visionary, wrote in 1965 of "Literary Machines,"computers that would enable people to write and publish in a new, nonlinear format, which he called hypertext. Hypertext was "nonsequential" text, in which a reader was not constrained to read in any particular order, but could follow links and delve into the original document from a short quotation. Ted described a futuristic project, Xanadu[®], in which all the world's information could be published in hypertext. For example, if you were reading this book in hypertext, you would be able to follow a link from my reference to Xanadu to further details of that project. In Ted's vision, every quotation would have been a link back to its source, allowing original authors to be compensated by a very small amount each time the quotation was read. He had the dream of a utopian society in which all information could be shared among people who communicated as equals.”
Nelson collaborated with Andries van Dam at Brown University in 1987 on the Hypertext Editing System, which was designed to produce printed documents nicely and efficiently on the IBM/360 system, but primarily to explore the hypertext concept. The Hypertext Editing System is described as “a pointer-rich data structure on arbitrary-length pages.”[Van Dam]

Nelson believes that his original ideas for hypertext have yet to be fully implemented. On its home page, the Project Xanadu website boldly states
“Today's popular software simulates paper. The World Wide Web (another imitation of paper) trivializes our original hypertext model with one-way ever-breaking links and no management of version or contents.
WE FIGHT ON.”[Xanadu]
Hypertext Explosion

Interest in hypertext finally exploded in 1987, due to the earlier release of Apple Computer’s of HyperCard , the release of Peter J. Brown’s GUIDE and Brown University’s Intermedia software. In November 1987, the first Association of Computer Machinery’s hypertext academic conference took place at the University of North Carolina. It was a huge success. According to Jakob Nielson’s 1987 Hypertext Bulletin ,

“When the workshop was originally planned in the fall of 1986, the planners were not sure whether they would be able to get a large enough set of papers and participants. But they had ended up having 500 people compete for the 200 seats at the
workshop.” [Nielsen]

Andries Van Dam presented the keynote address to the crowd about his earlier work in on the 1968 Hypertext Editing System. Ted Nelson and Douglas Engelbart were among the illustrious speakers at the 1987 Hypertext Conference.

Berners-Lee and the Web

In May of 1990, Tim Berners-Lee of CERN proposed the World Wide Web as a solution to the
communication problems of the widely-distributed CERN scientists. In his paper “Information Management: A
Proposal” Berners-Lee proposed a ‘Mesh’ that would solve CERN’s ‘information loss’ problem.
“Meanwhile, several programs have been made exploring these ideas (referring to an earlier discussion of hypertext), both commercially and academically. Most of them use "hot spots" in documents, like icons, or highlighted phrases, as sensitive areas. touching a hot spot with a mouse brings up the relevant information, or expands the text on the screen to include it. Imagine, then, the references in this document, all being associated with the network address of the thing to which they referred, so that while reading this document you could skip to them with a click of the mouse.”[Berners-Lee 2]

In a section entitled “What will the system look like?” Berners-Lee included the following diagram, which demonstrated the centrality of ‘hypertext’ to his idea of the ‘Mesh’.


Paradigm Transformation

Hypertext represented a radical departure from all textuality before its advent. In the time Vannevar Bush, the very idea seemed fanciful, yet inspiring. The exponentially increasing amount of information available after World War II made Bush keenly aware of the necessity of reducing the amount of time to locate information.

In addition to their technical and textual contributions to the concept of hypertext, Douglas Engelbart and Ted Nelson championed a vital part of Bush’s vision. In “As We May Think” the Memex that was proposed was a personal device in which “… an individual stores all his book, records, and communications”[Bush]. The Memex was a personal device. Engelbart and Nelson focused their research on the communication and record-keeping of individuals.

Hypertext simultaneously breaks language and unites people. The World Wide Web connected scientists initially and now connects the world. Instantaneous access to arcane information is possible by merely “Touching a hot spot with a mouse” in Berners-Lee’s words. Ted Nelson argues that hypertext breaks allows for escape from the tyranny of sequential text. An hypertext user can follow Alice down the rabbit hole and end up immersed in the saga of the origination of photography as a an art form .

Throughout the history of hypertext, you can catch glimpses of the extraordinary sparks of foresight that individuals have had. No one visionary can really claim the credit for what has become the modern concept of hypertext, yet the combined brilliance of its inventors has created something that we do not yet fully grasp.
