Researchers are set to present what they call an interactive flexible computer to a scientific conference on Tuesday, with the idea taking two forms: a 'PaperPhone' and a 'Snaplet' wristband computer.
The PaperPhone, pictured above, has a 3.7-inch flexible e-ink display. The researchers at the Queen's University Human Media Lab in Ontario worked with the E Ink Corporation, which provides the technology underpinning the screens of e-readers such as Amazon's Kindle, to develop the prototype computer.
According to the team, the flexibility of the display not only makes it easier to carry such devices in a pocket, but also allows for various new interactions with a smartphone.
The team collected 87 'bend gesture' pairs in total, with participants in trials recommending that three pairs — bending the side, the top corner and the bottom corner up and down — be standardised across applications. For example, bending the display upwards could be used to navigate left, while bending it down could be used to navigate right.
The team expects handheld mobile devices to provide the first commercial application for such technology, primarily because displays will be limited in size due to "technical reasons", but also because of the displays' portable nature.
According to a paper (PDF) that will be presented on Tuesday at the Association of Computing Machinery's Computer Human Interaction (CHI) 2011 conference in Vancouver, limitations of the prototype include the fact that it can only be bent on one side. The relatively slow refresh rate of flexible e-ink also makes real-time animations impossible.
The researchers published a video of the PaperPhone on YouTube on 3 May.
