1960s

In the 1960s Dartmouth BASIC programming language [7] was designed and implemented at Dartmouth College by John Kemeny and Thomas Kurtz. Over time BASIC became a popular language for home users, and business use, it introduced many people to programming as a hobby or career. Many of the modern concepts of computer graphics, dynamic objects and object oriented programming were prototyped by Ivan Sutherland in 1963 in Sketchpad [13][14]. In the mid 1960s Seymour Papert, a mathematician who had been working with Piaget in Geneva, came to the United States where he co-founded the MIT Artificial Intelligence Laboratory with Marvin Minsky. Papert worked with the team from Bolt, Beranek and Newman, led by Wallace Feurzeig that created the first version of Logo [25] in 1967. In the late sixties Alan Kay [2][3][17] used the term ‘personal computer’ and created a concept prototype, the FLEX Machine, he also envisaged a ‘Dynabook’ machine, the sketches for this look very similar to the laptop computers of recent years. The Simula [28] language was developed by Ole-Johan Dahl and Kristen Nygaard and this included Object-Oriented concepts. Douglas Engelbert’s worked on a project to augment the human intellect, as part of the Augment [8] project he demonstrate Hypertext and video conferencing.

1970s

Alan Kay joined the Xerox Palo Alto Research Center (PARC) [17][19] California in 1971. Throughout the seventies the group at PARC led by Dr. Kay developed an integrated programming language and programming environment called Smalltalk [10]. In the early seventies the Alto personal computer was created at the PARC. The Alto eventually featured the world’s first What-You-See-Is-What-You-Get (WYSIWYG) editor, a commercial mouse for input, a graphical user interface (GUI), and bit-mapped display, and offered menus and icons, and linked to a local area network. The Alto provided the foundation for Xerox’s STAR 8010 Information System. There was still a need to find a common use for a personal computer that would increase the demand for it. In 1978, Harvard Business School student, Daniel Bricklin, came up with the idea for an interactive visible calculator. Bricklin and Bob Frankston then co-invented the software program VisiCalc [1]. VisiCalc was a spreadsheet, and the first ‘killer’ application for personal computers as this application provided a justification for using personal computers as a productive tool.

1980s

During the 1980s ownership of personal computers became increasingly popular and many home users programmed using BASIC. In the early eighties IBM developed the first personal computer built from off the shelf parts (called open architecture) [15]. This included a command line operating system written by Microsoft and the Microsoft BASIC programming language. Apple developed the GUI further for the Lisa [5] that later became the Macintosh (Mac). The IBM style PC became most popular for business applications, while the Apple Mac was often used for Desktop publishing.

1990s

End User Programming research has continued to the present day. Research has continued in techniques of Visual Programming [9] e.g. Alice [4], Programming by Example [2][21], programming with automated assistance [20], and Natural Language Programming [27]. Squeak and Croquet[6] have developed from the early work in Smalltalk.

Tim Berners-Lee [23] developed HyperText Markup Language (HTML), and has been involved with the World Wide Web Consortium (W3C) [29] in developing standards base languages for the Web. This has encouraged the growth of the ‘Semantic Web’ [11] which allows both humans and computers to search and interact with pages more and so encouraged the development of interactive web pages and communities.

2000s

Recent, present and future research can enable the use of semantic web technologies, (developed from HTML by Tim Berners-Lee [23] and others), to enable End User Programming. This fusion of research and technologies is illustrated by Henry Lieberman’s home page [12] which has explanations of both areas of research. Examples of this fusion include Protégé [22], Jena [16], TopBraid Composer [24], and OpenCyc [18]. Information about these technologies is available in my semantic web page - http://www.cems.uwe.ac.uk/amrc/seeds/PeterHale/RDF/RDF.htm. A related development is that of web 2.0. Visual development environments based on AJAX (Asynchronous JavaScript And XML) [26] aim to reproduce on the web, the functionality provided by office tools such as Excel (which is often used as an End User Programming Environment). Information about Ajax and Web 2.0 is available in my Ajax/web2.0 page - http://www.cems.uwe.ac.uk/amrc/seeds/Ajax/ajax.htm.

I am a Researcher in the final year of my PhD. I specialise in applying Semantic Web techniques. My current research is on a technique of ‘User Driven Modelling/Programming’. My intention is to enable non-programmers to create software from a user interface that allows them to model a particular problem or scenario. This involves a user entering information visually in the form of a tree diagram. I am attempting to develop ways of automatically translating this information into program code in a variety of computer languages. This is very important and useful for many employees that have insufficient time to learn programming languages. I am looking to research visualisation, and visualisation techniques to create a human computer interface that allows non experts to create software.

I am a member of the Institute for End User Computing - http://www.ieuc.org/home.html.
