Architecture is taking off. Much of this is now coming off the drawing board. See if you can recognise any buildings being constructed now.

Watch please.

MIT’s Technology Review magazine featured 10 technoloical trends I'll be addresssing over the coming weeks.

They're interesting in as much as their title, as their content and context.

Peering into Video's Future. The Internet is about to drown in digital video. Hui Zhang thinks peer-to-peer networks could come to the rescue.

Nanocharging Solar. Arthur Nozik believes quantum-dot solar power could boost output in cheap photovoltaics.

Invisible Revolution. Artificially structured metamaterials could transform telecommunications, data storage, and even solar energy, says David R. Smith.

Personalized Medical Monitors. John Guttag says using computers to automate some diagnostics could make medicine more personal.

Single-Cell Analysis. Norman Dovichi believes that detecting minute differences between individual cells could improve medical tests and treatments.

A New Focus for Light. Kenneth Crozier and Federico Capasso have created light-focusing optical antennas that could lead to DVDs that hold hundreds of movies.

Neuron Control. Karl Deisseroth's genetically engineered "light switch," which lets scientists turn selected parts of the brain on and off, may help improve treatments for depression and other disorders.

Nanohealing. Tiny fibers will save lives by stopping bleeding and aiding recovery from brain injury, says Rutledge Ellis-Behnke.

Digital Imaging. Reimagined Richard Baraniuk and Kevin Kelly believe compressive sensing could help devices such as cameras and medical scanners capture images more efficiently.

Augmented Reality. Markus Kähäri wants to superimpose digital information on the real world.

Augmented Reality

Click title for video.

Augmented Reality is a specialization of computer vision that attempts to extract the 3D structure of a scene from video and then insert with high precision virtual or 3D objects into the scene. AR can be useful in many applications including entertainment, heads-up displays, tourism and surgical visualization.

Consider for example visiting a foreign country and not having a map. If you want directions to your hotel from any location in the city then you can just take a photo with your cell phone camera and using the phone’s build-in AR software determine your location; the AR software would then retrieve directions wirelessly from a large database and present them to you by annotating the original photo. Another application would be retrieving information about a historical monument that you are looking at. An example of AR is shown in the following video from related research at the University of British Columbia.
