Arjan at the Mobile Games Blog has posted about a story on Cnet regarding motion sensors in mobile phones.
The technology is based on accelerometers, which measure acceleration, and gyroscopes, which measure rotation. These tiny sensors already power the Nintendo Wii’s Wiimote, and the addition of them to handhelds could see use in a wide variety of applications, including gaming.
“My sense is we are on the edge of seeing an explosion of more and more devices using motion sensors, and specifically MEM (micro-electromechanical) accelerometers,” said Christophe Lemaire of Analog Devices, which is one of the largest manufacturers of accelerometers. “We are already working with all the tier-one phone manufacturers as well with other third-party application developers to fuel this explosion.”
The sensors are already used in some phones. Apple’s iPhone, one of the first to use them in the US, detects when the phone is titled and changes the display accordingly, amongst other things. The Samsung SCH-S310, released in Asia in 2005, allows users to write numbers in the air with the phone to dial them. On the gaming side, Vodafone’s Sharp V603SH allows users in Japan to use the phone as a controller for mobile games, such as swinging it like a golf club.
The full article goes more in-depth on the technology, with quotes from a number of people in the industry.
