Vocabulary of computer interaction may still be nascent
Computer have a Language of interaction—clicking, scrolling, dragging, typing are some of the core "verbs" in the proto-language that is digital interfaces. However these are just the building blocks upon which more complex words and structures of interaction can evolve.
Some neologists of computer interaction:
An interesting project would be to document both well-established and experimental forms of interaction to map out the possibility space and begin to see the interconnections between different experiments in interfaces. I would call this: Encyclopedia Interactica.
Side note: Dreaming of high tech HCI such as brain-computer interfaces where we can control computers with our thoughts is like dreaming about telepathic communication instead of figuring out how to use the language of today to better express your thoughts.
