Kleurenfoto's van het Tsarenrijk

Tussen 1904 en 1916 maakte Sergej Prokoedin-gorski (1863-1944) kleurenfoto's van het groot Russisch rijk. Indrukwekkend.

Maar naast het feit dat er geen spijkerbroeken te zien zijn bij de mensen op de foto's en dat er geen asfalt ligt (bijna geen enkele verharde weg), is toch wel dat er geen auto's op de foto's staan. Geen enkele auto wel te verstaan...

The Display That Watches You

For decades, engineers have envisioned wearable displays for pilots, surgeons, and mechanics. But so far, a compact wearable display that's easy to interact with has proved elusive.

Researchers at Fraunhofer Institute for Photonic Microsystems (IPMS) have now developed a screen technology that could help make wearable displays more compact and simpler to use. By interlacing photodetector cells--similar to those used to capture light in a camera--with display pixels, the researchers have built a system that can display a moving image while also detecting movement directly in front of it. Tracking a person's eye movements while she looks at the screen could allow for eye-tracking control: instead of using hand controls or another form of input, a user could flip through menu options on a screen by looking at the right part of the screen. The researchers envisage eventually integrating the screen with an augmented-reality system.
