For example, when a PaperTab is placed beyond reaching distance, it reverts to a thumbnail overview of the document, like icons on a desktop computer. When the tab is picked back up or touched, it switches back to a full screen view, like opening a new window.
Additionally, PaperTab's interface allows functions simply by tapping tabs together. For example, a photo can be sent via email simply by tapping a tab of a draft email together with a tab of a photo. Even cooler, when that email is ready to go, it can be sent by bending the top corner of the display. Also, placing tabs side by side can create a larger display surface.
Designers say these functions emulate the natural handling of multiple sheets of paper. This may sound like a cluttered step back, but think how long it takes to back track through a tablet to close out or switch apps as opposed to picking up a piece of paper that's right in front of you.
"Using several PaperTabs makes it much easier to work with multiple documents," Roel Vertegaal, Director of Queen's University's Human Media Lab said on the university's website. "Within five to ten years, most computers, from ultra-notebooks to tablets, will look and feel just like these sheets of printed color paper."
