An iPad That Fits Your Pocket: a Roll-up Tablet With Flexible Screen Real Estate


Researchers at Queen's Human Media Lab have designed a flexible display into what they describe as a rollable touch-screen tablet.

Dubbed the MagicScroll, the design includes a 7.5" 2K resolution flexible display that can be rolled or unrolled around a central, 3D-printed cylindrical body containing the device's control electronics.

The rollable touch-screen tablet has been designed to capture the seamless flexible screen real estate of ancient scrolls in a modern-day device. Led by bendable-screen expert Dr. Roel Vertegaal, this new technology is set to push the boundaries of flexible device technology into brand new territory.

Two rotary wheels at either end of the cylinder allow the user to scroll through information on the touch screen. When a user narrows in on an interesting piece of content that they would like to examine more deeply, the display can be unrolled and function as a tablet display. Its light weight and cylindrical body makes it much easier to hold with one hand than an iPad. When rolled up, it fits your pocket and can be used as a phone, dictation device or pointing device.

"We were inspired by the design of ancient scrolls because their form allows for a more natural, uninterrupted experience of long visual timelines," says Dr. Vertegaal, Professor of Human-Computer Interaction and Director of the Queen's University Human Media Lab. Another source of inspiration was the old rolodex filing systems that were used to store and browse contact cards. The MagicScroll's scroll wheel allows for infinite scroll action for quick browsing through long lists. Unfolding the scroll is a tangible experience that gives a full screen view of the selected item. Picture browsing through your Instagram timeline, messages or LinkedIn contacts this way!"

Beyond the flexible display, the prototype also features a camera that allows users to employ the rolled-up MagicScroll as a gesture-based control device - similar to that of Nintendo's Wiimote. And the device's rotary wheels contain robotic actuators that allow the device to physically move or spin in place in various scenarios, like when it receives a notification for instance.

"Eventually, our hope is to design the device so that it can even roll into something as small as a pen that you could carry in your shirt pocket," says Dr. Vertegaal. |More broadly, the MagicScroll project is also allowing us to further examine notions that 'screens don't have to be flat' and 'anything can become a screen'. Whether it's a reusable cup made of an interactive screen on which you can select your order before arriving at a coffee-filling kiosk, or a display on your clothes, we're exploring how objects can become the apps.

Dr. Vertegaal's Human Media Lab collaborator Juan Pablo Carrascal will be presenting MagicScroll at MobileHCI, one of the leading international conferences on Human-Computer Interaction with mobile devices and services, in Barcelona, Spain on September 4, 2018.

The Human Media Lab is one of Canada's premier media laboratories. Its mandate is to develop disruptive technologies and new ways of working with computers that are viable 10 to 20 years from now.
