Aims to replace paper with touchscreen e-ink display for note taking
Sony has been working on a device for using e-ink as digital paper in an educational setting. Aimed at universities as a replacement for pen and paper-based notetaking by students, the prototype is a 13.3-inch, 1200x1600-resolution, 16-level gray scale e-ink display-as-tablet with touchscreen capabilities, as well as stylus input for drawing and writing.
Similar in size to an A4 sheet of paper, the 6.8mm (0.26-inch) device weighs 358 grams (12.6 ounces), making it a lighter and larger alternative to using a tablet for the same purpose. The slate is able to use PDFs for reading and editing, with notes able to be applied to documents and saved to its 4GB of internal memory or a microSD card. While it can connect to a Wi-Fi network, when it is switched off it is capable of being used for up to three weeks.
Currently, the e-ink slate is being tested in three Japanese universities, with the company hoping to commercialize it in the 2013 fiscal year.
