This struck me as a very interesting quote from Steve Jobs
There are no â€œverbsâ€ in the iPhone interface, he said, alluding to the way a standard mouse or stylus system works. In those systems, users select an object, like a photo, and then separately select an action, or â€œverb,â€ to do something to it.
That is a very good way of thinking about next generation user interfaces, no verbs, just objects you can use.
Funnily the same happened with adventure games. In early adventures you always had an object and a verb, like “Use ‘Key’ on ‘door’ “. With time it simplified to dragging the key onto the door. Sometimes even just walking through the door ( your character is by now clever enough to try to use the key ) works.
