'In-between,' 'hover,' 'unfixed.'

'In-between,' 'hover,' 'unfixed.' These words remind me the cursor on the display. I took up them from the book about "Window｜Interface." We often consider about what the window is, but we have to consider about what the cursor is. I think that the cursor is the representation of our age, especially latest 30years,1980-2010.

The absolute thin electric device

I'm interested in the absolute thin for the electric device, especially touch interface one like iPhone. What is the thin for the interface? The thin is not the plane but the object. For example, even though the card is the plane when we look at it, it changes to the object when we touch it. Can we decide the point between the plane and the object? The electrical device becomes thinner and thinner, at last it will get absolute thinness. What will we feel this absolute thin electrical device? Is it the plane or the object? Is it only the display or not? Is it the only image or not?
