MEMS gyroscopes full time from the start-MEMS smartphone gyroscope – the electronics industry
Recent market there is an open secret, is the first built-in micro-electromechanical system gyroscope (MEMSgyroscope) mobile phone will be come out in June. Analysts speculated that support mobile phone supplier may be Apple (it is iPhone4G), High Tech Computer (HTC), is also possible that ST-Ericsson; and no matter who is the industry's first, is expected by 2012, each Smart phone maker will keep up this trend.
Analysts said gyroscope in the field of smart phones "everywhere", because this type of component will support the new user interface to enhance the online gaming experience, and by dead reckoning (deadreckoning) to provide indoor navigation; also can achieve the so-called "augmented reality (augmented-reality)" application, that is, the number of mobile phone cameras to point to a target, to show information about the object.

iSuppli analyst said, Apple's iPhone to various mobile phone supplier insight into the MEMS accelerometer can transform images through motion control display orientation (horizontal or straight) of the skill; Nintendo (Nintendo) for Wii games machine used MotionPlus joystick, then through proof of a "six-axis" solution axis accelerometers with three-axis gyroscope How to make a more smooth movement and accurate identification of interfaces to inspire the unlimited mobile phone manufacturers imagine.
MEMS gyroscopes supplier InvenSense games and 3D user interface operations Marketing Director DougVargha said, if only using the accelerometer: "You will not be responsive, but the larger the output noise is the slow response, but more pure output; but if the combination of accelerometers and gyroscopes, can be both pure Also responsive output. "
He explained that with the accelerometers alone can not determine the difference between movement and gravity, but with the gyroscope, we can immediately sense the occurrence of movement, so that the user interface more responsive, are not subject to blur (artifacts) Interference . InvenSense Wii's MotionPlus for the joystick device to provide additional Chip ; The kinds of attachments are deducted in the end joystick, 3D can detect the full range of angular momentum (angularmomentum). (Accelerometers measure linear acceleration only)
According to iSuppli's statistics, digital camera anti-shake function for the application of bulk, size in 2009 was 4.47 billion dollars in the overall MEMS gyroscope market, will grow in 2012 to more than 769 million US dollars. Another market research firm ForwardConcepts founder WillStrauss predicts the global mobile phone market with the MEMS gyroscope from the current 3,800 million in 2012 to 7,000 million U.S. dollars to expand the scale.
InvenSense MikeHousholder mobile business unit director of marketing, said, MEMS gyroscope market success the first digital camera in the field of application, current penetration rate of almost 100%: "At present, more than five megapixels digital camera and digital camera products, almost all built-in gyroscope. "
The situation in the mobile space is similar, MEMS gyroscopes is also being used to provide the first embedded digital camera anti-shake function: "As smart phones inherited higher pixel digital camera from 500, 8 100, from 10 million to 12 million have these phone cameras capture the image quality is very dependent on anti-shake function. "Housholder said.
But once stationed handsets, gyroscopes can also be used to strengthen the online gaming experience, indoor navigation, augmented reality and other functions, as well as significantly expanding the scope of action instructions; for example, can be adjusted by phone upside down Mute , shook his cell phone will be able to make a call, and even brought the phone in the air "signature" evidence such as transactions.
