Sites that I found interesting for July 7th 2009 through July 8th 2009:
- A Twitter Augmented Reality App for iPhone – There's a fascinating new Twitter app in development called TwittARound, an augmented reality Twitter viewer for the iPhone 3GS. With the app, you can see live tweets around your location and you can even see how far away they are. To accomplish this, TwittARound uses a combination of the iPhone's compass and its accelerator-enabled GPS to determine the location of tweets and then layers those on top of a live video feed. Cooool!
- Interplanetary internet gets permanent home in space – While the Earth-bound internet uses a protocol called TCP/IP to allow distant machines to communicate over cables, the ISS payload uses delay-tolerant networking (DTN), which is being developed to cope with the patchy coverage in space that arises when spacecraft pass behind planets or suffer power outages.
- Scientists Develop Echolocation In Humans To Aid The Blind – A team of researchers from the University of Alcalá de Henares (UAH) has shown scientifically that human beings can develop echolocation, the system of acoustic signals used by dolphins and bats to explore their surroundings. Producing certain kinds of tongue clicks helps people to identify objects around them without needing to see them, something which would be especially useful for the blind.
