The meaning of HAL has been given both as "Heuristically programmed ALgorithmic computer" and as "Heuristic ALgorithmic computer". The former appears in Clarke's novel of "2001" and the latter in his sequel novel "2010". In computer science, a heuristic is a programmable procedure not necessarily based on fixed rules, producing informed guesses often using trial-and-error. The results can be false such

Rudimentary voice-controlled computing began in the early 1980s with the SoftVoice Computer System and existed in more sophisticated form by the early 2000s, although not as sophisticated as depicted in the film. The first picture phone was demonstrated at the 1964 New York World's Fair; however, due to the bandwidth limitations of telephone lines, personal video communication did not succeed commercially and has only been practical over broadband internet connections. Personal (audio) wireless telephones were ubiquitous in 2001, and
