A Liquid Crystal based Contact Lens Display

Switching of a contact lens shaped display. The contact lens is still transparent but is able to modulate the transmitted light using LCD technology. Direct applications could be medical, as an artificial iris, or cosmetic, as an iris with tunable color, or it just could serve as a gimmick. The dollar sign is a reference to the many cartoons featuring people/figures with dollars in their eyes 🙂

When worn, the image would only be visible to bystanders, since the eye cannot focus on objects in such a close proximity. Research is currently being performed to solve the focusing problem and to see whether an embedded contact lens display that can be seen by the lens wearer is feasible.

All work was performed in the Centre for Microsystems Technology, Ghent University, Belgium.

Enabling Concurrent Dual Views on Common LCD Screens

Can your laptop show you two different views simultaneously?

The answer is yes and here is how. Twisted Nematic (TN) is the most widely used LCD technology today, especially on laptop screens. Some color combinations may become indistinguishable when viewed at a certain angle. Exploiting this, we can hide and show information at different angles without special hardware. Two completely different images can be shown at different viewing angles by spatial multiplexing or by temporal multiplexing. Our method works across various TN-based LCD screens. Similarly, two movies or video games can be played simultaneously for different viewing angles, allowing people to watch different programs or play video games with personalized views.

Prismatica

Prismatica consists of an arrangement of pyramid-shaped crystals affixed to an LCD screen and illuminated with programmed geometric animation. The animated patterns are precisely mapped to the vertices of the crystals, illuminating them individually and in formation. The animations are further refracted through the geometry of the crystals in accordance with the shifting perspective of the observer, which in turn alters the way the illuminations appear and interact with reflections of surrounding lights within the space.

Microsoft Holoflector

Holoflector is a unique, interactive augmented-reality mirror. Graphics are superimposed correctly on your own reflection to enable a novel augmented-reality experience. Presented at Microsoft TechForum 2012, Holoflector leverages the combined abilities of Kinect and Windows Phone to infer the position of your phone and render graphics that seem to hover above it.
