This concept PC takes the idea of a cup of into a system of holographic touch screens and infrared communication.
The cup contains a holographic projector and serves as the main interface of the Cup PC. It uses other types of interactivity like stacking cups to share data, pouring data and other very farfetched features. The concept seeks to make computer use easy for everybody without the need to connect to a device such as USB.
According to the concept designers, everyone should be able to interact with other users, store and check information by physical behavior only such as grappin, filing and pouring etc. and the user interaction, store and check the information by only physical behaviors (grappling, filing up and pouring, etc). This is just a concept but it seems kind of far fetched to me right now.
