The device is comprised of a high-resolution, 7.5″ 2K resolution flexible display that can be rolled or unrolled around a central, 3-D-printed cylindrical body containing the device’s computerized inner-workings. 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.
