laser keyboard

Accessibility: The accessibility of this laser keyboard is similar to the normal keyboard, but the size of the key button is much bigger than the “actual” keyboard. (The size of key is adjustable.)

Aesthetic-Usability: I think this laser keyboard considered both aesthetic and usability. The projective keyboard looks really cool and high-tech. Just like the invention in the science fiction. Also, it is extremely saving place, as the projector is as tiny as a cell-phone.

Ockham’s Razor: I think this design is fitted in with “Ockham’s razor” theory. The design here is obviously aimed to fix the problem of placing space. The virtual feature of laser keyboard fixed this problem in the simplest way.

Performance vs. Preference: This keyboard is considered the habit of the “qwerty” keyboard-users and it is just changing the form of a keyboard from an actual piece of plastic to a laser beam. It is also a memorable design by the way it performs.
