The inner sleeve artwork, created by Emil Schult and photographed by Günter Fröhling, depicts four slightly robotic-looking mannequins (representing the band members engaged in studio activities: performing, recording, mixing), similar to the artwork of the previous album, The Man-Machine, also created by Fröhling.

In two photos, the mannequin representing Karl Bartos is seen playing a Stylophone, an instrument which is featured on the track "Pocket Calculator".

[11] The track "Computer Love" was released as a seven-inch single in the UK, in June 1981, backed with "The Model", from the group's previous album The Man-Machine.

"Pocket Calculator" was released as a seven-inch single in the USA by Warner Brothers in 1981, pressed on a fluorescent yellow/lime vinyl, matching the color of the album cover.

Kraftwerk issued several different versions of the single "Pocket Calculator" in different languages: namely, German ("Taschenrechner"), French ("Mini Calculateur"), and Japanese ("Dentaku", or 電卓).

Smash Hits reviewer David Hepworth described the content as "predictable" and "gimmicky" and not the presumed step forward by the group: "Kraftwerk are seemingly content to tootle around on their instrument panels in the service of a bunch of non-songs about pocket calculators and computers", Hepworth wrote, giving the album a 4 out of 10 rating.

In 1982, American DJ and rapper Afrika Bambaataa wrote the song "Planet Rock" and recorded chords inspired from Trans-Europe Express.

[29] Señor Coconut y su Conjunto, an electronic project of German musician Uwe Schmidt which initially covered Kraftwerk's songs, published a merengue-styled version of "It's More Fun to Compute" on their first LP El Baile Alemán, wrongly labeled as "Homecomputer" on the sleeve.

La Roux used the main riff from "Computer Love" in their song "I'm Not Your Toy" from their self-titled debut album.

Ulf Ekberg of Ace of Base, when asked what brought him to music, if he had to boil it down to one reason, responded with: "In one word: Kraftwerk.

Once Kraftwerk released their 1981 album Computerwelt it all became clear to me: they showed the world that you can combine music with technology and be successful with it — and that was exactly what I wanted to do.

"[34] The original 1981 sleeve notes are relatively unspecific regarding roles, merely listing all the equipment suppliers and technicians under the heading "Hardware" and the various other people involved, such as photographers, as "Software".
