"Books use folding as both a navigational and space saving technique, and paper maps have malleable display sizes.
"The PaperFold smartphone adopts folding techniques that makes paper so versatile, and employs them to change views or functionality of a smartphone, as well as alter its screen real estate in a flexible manner. PaperFold demonstrates how form could equal function in malleable mobile devices," Vertegaal said.
The PaperFold was unveiled at the ACM CHI 2014 conference in Toronto.
