In the 1960s, Douglas Engelbart developed features of modern computing, like the mouse and hypertext, now standard. His 1968 demo, “The Mother of All Demos,” showcased groundbreaking innovations in computing. Engelbart’s interface, the keyset, allowed for typing without moving one’s hand by pressing multiple keys simultaneously. Despite its unique design, the keyset failed to catch on. In connecting the keyset to a modern computer via USB, the process involved overcoming challenges to mimic keyset functionality. However, user feedback on the physical difficulty of using the keyset was mixed. The legacy of Engelbart’s work continues to influence modern technology developments.
