Motion -sensing now on Mobile phones
Sunday, March 25th, 2007 
The technology used in Nintendo’s popular Wii video game console with the help of which bowl strikes and hit tennis volleys is now eyeing towards mobile handsets. Responding to a flick of the wrist or sweep of the arm, tiny sensors called accelerometers, which measure linear acceleration in the Wiimote game controller, translate motion into action on the screen, CNET NEWS says.
When the technology is used in a cell phone, the functionality of the gadget becomes multi-purpose. It can function as a motion-sensing mouse that helps in browsing mobile Internet. It also allows you to monitor a fitness workout by measuring the number of steps you take, your speed and the calories burned. As accelerometers advanced from one-axis to two-axis to three-axis measurement capabilities, their accuracy has improved dramatically.
The report says Analog Devices, one of the largest manufacturers of accelerometers, has already supplied more than 300 million of the devices to consumer electronics makers over the past decade and Christophe Lemaire, the company’s marketing manager, opines that the market is set to explode as more of these components make their way into cell phones.
