A loud clatter of gunk music flooded through the Heart of Gold cabin as Zaphod searched the sub-etha radio wave bands for news of himself. The machine was rather difficult to operate. For years radios had been operated by means of pressing buttons and turning dials; then as the technology became more sophisticated the controls were made touch-sensitive—you merely had to brush the panels with your fingers; now all you had to do was wave your hand in the general direction of the components and hope. It saved a lot of muscular expenditure, of course, but meant that you had to sit infuriatingly still if you wanted to keep listening to the same program.

The Hitchhiker’s Guide to the Galaxy

Tiba-tiba saja ketemu kutipan dari buku The Hitchhiker’s Guide to the Galaxy dari penulis Douglas Adams. Kutipan tersebut menceritakan tentang Radio yang sudah bertahun-tahun dioperasikan menggunakan tombol, lalu diganti dengan kontrol berupa sentuhan, dan akhirnya cuma diganti dengan gestur.

Sangat mirip dengan keadaan hari ini, padahal ini buku terbitan tahun 1979 🙂
