We introduce Glassified, a modified ruler with a transparent display to supplement physical strokes made on paper with virtual graphics. Because the display is transparent, both the physical strokes and the virtual graphics are visible in the same plane.
A digitizer captures the pen strokes in order to update the graphical overlay, fusing the traditional function of a ruler with the added advantages of a digital, display-based system. We describe use-cases of Glassified in the areas of math and physics and discuss its advantages over traditional systems.
The Ruler is embedded with -> TOLED display, Digitizer to track pen input.
Source code for Glassified 0.1 is released. Its kind of messy right now but you should be able to compile it with VS2010 . Instructions to replicate the system will be up soon.
Moving forward we explored the LittleAR, paper bookmark form factor.
LittleAR was motivated by the observation of users who have held on to paper, despite powerful incentives to adopt electronic devices such as Kindle, tablets, etc.
LittleAR is a 2-inch transparent OLED and a mouse sensor combined in a form similar to a paper bookmark. The design naturally affords translation on paper such that the user can move it along paper similar to a magnifying glass.
The advantage of using a thin OLED display is that it allows graphical augmentations to be almost in the same plane as the paper, which creates a seamless fusion of the virtual and real world. This preserves the aesthetics of the printed books while giving the user an option to see the printed text/image augmented with dynamic text and graphics.
