The KiddiComp concept, envisioned by Alan Kay in 1968 while a PhD candidate, [2] [3] and later developed and described as the Dynabook in his 1972 proposal "A personal computer for children of all ages", [1] outlines the requirements for a conceptual portable educational device that would offer similar functionality to that now supplied via a laptop computer or (in some of its other incarnations) a tablet or slate computer with the exception of the requirement for any Dynabook device offering near eternal battery life. Adults could also use a Dynabook, but the target audience was children.
Part of the motivation and funding for the Dynabook project came from the need for portable military maintenance, repair, and operations documentation.[ citation needed ] The prospect of eliminating the need to move large amounts of difficult-to-access paper in a dynamic military theater led to significant US Department of Defense funding.
Though the hardware required to create a Dynabook is here today, Alan Kay still[ when? ] thinks the Dynabook hasn't been invented yet, because key software and educational curricula are missing.[ citation needed ] When Microsoft came up with its tablet PC, Kay was quoted as saying "Microsoft's Tablet PC, the first Dynabook-like computer good enough to criticize". [4]
Toshiba also has a line of sub-notebook computers called DynaBooks. In June 2018, Sharp acquired a majority stake in Toshiba's PC business including laptops and tablets sold under the Dynabook brand. [5] [6]
Describing the idea as "A Personal Computer For Children of All Ages", Kay wanted the Dynabook concept to embody the learning theories of Jerome Bruner and some of what Seymour Papert — who had studied with developmental psychologist Jean Piaget and who was one of the inventors of the Logo programming language — was proposing. This concept was created two years before the founding of Xerox PARC. The ideas led to the development of the Xerox Alto prototype, which was originally called "the interim Dynabook". [7] [8] [9] It embodied all the elements of a graphical user interface, or GUI, as early as 1972. The software component of this research was Smalltalk, which went on to have a life of its own independent of the Dynabook concept.
The hardware on which the programming environment ran was relatively irrelevant.
At the same time, Kay tried in his 1972 article to identify existing hardware components that could be used in a Dynabook, including screens, processors and storage memory. For example:
A standalone 'smart terminal' that uses one of these chips for a processor (and includes memory, a keyboard, a display and two cassettes) is now on the market for about $6000. [1]
The Dynabook vision was most fully laid out in Kay’s 1977 article "Personal Dynamic Media", co-authored with collaborator (and Smalltalk co-inventor) Adele Goldberg. [9]
In 2019, Kay gave a detailed answer to a question on Quora, about the origins of the Dynabook concept. [10]
Since the late 1990s, Kay has been working on the Squeak programming system, an open source Smalltalk-based environment which could be seen as a logical continuation of the Dynabook concept. [11]
He was actively involved in the One Laptop Per Child project, which uses Smalltalk, Squeak, and the concepts of a computer for learning. [12] [8]
Alan Curtis Kay is an American computer scientist best known for his pioneering work on object-oriented programming and windowing graphical user interface (GUI) design. At Xerox PARC he led the design and development of the first modern windowed computer desktop interface. There he also led the development of the influential object-oriented programming language Smalltalk, both personally designing most of the early versions of the language and coining the term "object-oriented." He has been elected a Fellow of the American Academy of Arts and Sciences, the National Academy of Engineering, and the Royal Society of Arts. He received the Turing award in 2003.
Smalltalk is a purely object oriented programming language (OOP) that was originally created in the 1970s for educational use, specifically for constructionist learning, but later found use in business. It was created at Xerox PARC by Learning Research Group (LRG) scientists, including Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Diana Merry, and Scott Wallace.
Squeak is an object-oriented, class-based, and reflective programming language. It was derived from Smalltalk-80 by a group that included some of Smalltalk-80's original developers, initially at Apple Computer, then at Walt Disney Imagineering, where it was intended for use in internal Disney projects. The group would later go on to be supported by HP Labs, SAP, and most recently, Y Combinator.
The Xerox Alto is a computer system developed at Xerox PARC in the 1970s. It is considered one of the first workstations or personal computers, and its development pioneered many aspects of modern computing. It features a graphical user interface (GUI), a mouse, Ethernet networking, and the ability to run multiple applications simultaneously. It is one of the first computers to use a WYSIWYG text editor and has a bit-mapped display. The Alto did not succeed commercially, but it had a significant influence on the development of future computer systems.
The Xerox Star workstation, officially named Xerox 8010 Information System, is the first commercial personal computer to incorporate technologies that have since become standard in personal computers, including a bitmapped display, a window-based graphical user interface, icons, folders, mouse (two-button), Ethernet networking, file servers, print servers, and email.
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is fitted inside the lower lid enclosure under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers.
Adele Goldberg is an American computer scientist. She was one of the co-developers of the programming language Smalltalk-80, which is a computer software that simplifies the programming language, and has been the basis of knowledge and structure for many other programming languages such as Python, C, and Java. She also developed many concepts related to object-oriented programming while a researcher at the Xerox Palo Alto Research Center (PARC), in the 1970s.
The office of the future is a collection of ideas for redesigning the office. As technology and society have evolved, the definition of the office of the future has changed. Current concepts, dating from the 1940s, are now known as the "paperless office".
Lawrence Gordon Tesler was an American computer scientist who worked in the field of human–computer interaction. Tesler worked at Xerox PARC, Apple, Amazon, and Yahoo!.
Daniel Henry Holmes Ingalls Jr. is a pioneer of object-oriented computer programming and the principal architect, designer and implementer of five generations of Smalltalk environments. He designed the bytecoded virtual machine that made Smalltalk practical in 1976. He also invented bit blit, the general-purpose graphical operation that underlies most bitmap computer graphics systems today, and pop-up menus. He designed the generalizations of BitBlt to arbitrary color depth, with built-in scaling, rotation, and anti-aliasing. He made major contributions to the Squeak version of Smalltalk, including the original concept of a Smalltalk written in itself and made portable and efficient by a Smalltalk-to-C translator.
Charles Patrick "Chuck" Thacker was an American pioneer computer designer. He designed the Xerox Alto, which is the first computer that used a mouse-driven graphical user interface (GUI).
The Xerox NoteTaker is a portable computer developed at Xerox PARC in Palo Alto, California, in 1978. Although it did not enter production, and only around ten prototypes were built, it strongly influenced the design of the later Osborne 1 and Compaq Portable computers.
Etoys is a child-friendly computer environment and object-oriented prototype-based programming language for use in education.
The Satellite Pro is a line of laptop computers designed and manufactured by Dynabook Inc. of Japan, which was formerly Toshiba's computer subsidiary. The Satellite Pro is currently positioned between their consumer E series and their business Tecra series of products.
Pen computing refers to any computer user-interface using a pen or stylus and tablet, over input devices such as a keyboard or a mouse.
The Portégé is a range of business-oriented subnotebooks and ultrabooks manufactured by Dynabook Inc. From 1993 to 2018, the Portégé was manufactured by Toshiba's computer subsidiary before Sharp Corporation purchased majority interest in it.
The history of tablet computers and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914. The first publicly demonstrated system using a tablet and handwriting recognition instead of a keyboard for working with a modern digital computer dates to 1956.

Ted Kaehler is an American computer scientist known for his role in the development of several system methods. He is most noted for his contributions to the programming languages Smalltalk, Squeak, and Apple Computer's HyperCard system, and other technologies developed at Xerox PARC.
Dynabook Inc., formerly Toshiba Client Solutions Co., Ltd., is a Japanese personal computer manufacturer owned by Sharp Corporation; it was owned by, and branded as, Toshiba from 1958 to 2018. It claims its Toshiba T1100, launched in 1985, as the first mass-market laptop PC. Toshiba had used "DynaBook" or "dynabook" as a sub-brand since 1989, but Dynabook became the worldwide brand in 2019.
