Então eu investiguei sobre o "opton" (mencionado por DVK) de Return from the Stars (1961), por Stanislaw Lem e acontece que ele usa uma interface de toque. Aqui está uma citação do livro, já que a resposta não mencionou:
Chapeter 3:
The bookstore resembled, instead, an electronic laboratory. The books were crystals with recorded contents. They could be read with the aid of an opton, which was similar to a book but had only one page between the covers. At a touch, successive pages of the text appeared on it. But optons were little used, the sales-robot told me
E eu encontrei um exemplo ainda anterior na Fundação de Issac Asimov (1951) com o "bloco de cálculo"
Capítulo 4:
"Before you are done with me, young man, you will learn to apply psychohistory to all problems as a matter of course. –Observe." Seldon removed his calculator pad from the pouch at his belt. Men said he kept one beneath his pillow for use in moments of wakefulness. Its gray, glossy finish was slightly worn by use. Seldon's nimble fingers, spotted now with age, played along the files and rows of buttons that filled its surface. Red symbols glowed out from the upper tier.
Também mencionado em uma das respostas (por DJClayworth) é um exemplo de não-ficção, o "memex", descrito em
And his trails do not fade. Several years later, his talk with a friend turns to the queer ways in which a people resist innovations, even of vital interest. He has an example, in the fact that the outraged Europeans still failed to adopt the Turkish bow. In fact he has a trail on it. A touch brings up the code book. Tapping a few keys projects the head of the trail. A lever runs through it at will, stopping at interesting items, going off on side excursions. It is an interesting trail, pertinent to the discussion. So he sets a reproducer in action, photographs the whole trail out, and passes it to his friend for insertion in his own memex, there to be linked into the more general trail.
