What computer accessory was the result of the work on human-computer interaction by the creator of hypertext?
Purple Numbers Purple Numbers is a suite of tools that allows one to address paragraphs of HTML content. It was originally conceived by Douglas Engelbart for his creation of hypertext. The name comes from the faint, purple numbers at the end of each paragraph, which represent the link to that paragraph. The name was coined by Christina Engelbart, Doug's daughter.
Rick Gates Rick Gates (born October 18, 1956) is an Internet pioneer mostly known because he organised The Internet Hunt and raised the ideas of Interpedia. He studied at the Graduate Library School at the University of Arizona. In 1992 he started the monthly competition "The Internet Hunt" where questions had to be answered exclusively using sources on the Internet. Utilities of investigation were Usenet, FTP, Gopher and Telnet (NCSA Mosaic, the first popular Web browser was first published in April 1993). When the World Wide Web became more popular, the competition was closed in October 1994.
