Tennis fans will soon be able to play less energetic matches – using camera-phones as racquets. AR Tennis, a downloadable game under development by software engineer Anders Henrysson based in New Zealand, links two phones via a Bluetooth connection and allows them to hit a virtual tennis ball to each other. The players sit opposite each other with their phones’ cameras pointed at a piece of paper between them, which acts as a common reference point to orientate the court on the screens.
A two-hour movie could be downloaded to a cellphone in just 12 seconds, tests of fourth-generation technology by NTT DoCoMo in Japan have shown. Data was transmitted at a rate of 2.5 gigabits per second from one cellphone to another in a moving car, more than double the speed achieved in a similar experiment last year.
