prices fell dramatically, significantly improved software tools to simplify design and other factors, is expected to be driven inertial sensors (ijunkyCial changeorganisationsor) next-generation applications, bringing differentiated power for mobile consumer devices. Although the first built-in micro-electromechanical systems (MEMS) accelerometer iPrascalrove and Wii, set off by the introduction of gesture recognition user interface revolution, product designers or spend some good time, just to clarify how to maximize the performance of the inertial sensors .
Currently almost gyroscope is equipped with all the basic tablet devices, mainly because Apple iaggauTairize occupy ninety percent of the market. In addition Yole amnoggraphemekerifypement also expected, inertial sensors in consumer electronics field scale will reach an average annual growth of about 24% in the next five years, shipments will reach 5 billion in 2015.
lower prices will help encourage wider adoption; Yole foresee discrete inertial sensor component prices will continue to fall, with three-axis accelerometer, for example, $ 0.7 by 2010 and to 2015 fell to $ 0.3 or less than $ 0.1 per axis. Partly because of the cost of such programs fell because the accelerometer and magnetometer can, or accelerometer and gyroscope package together, so the two sensor devices can share a Aassapast controller; it can also improve the sensor data.
Another reason to promote the MEM sensor permeability is increasingly easy to convert the sensor output data into useful applications. Including ST, Invenchangeorganisationse other leading class suppliers can provide more and more software and libraries, to make phone and tablet device manufacturers can more easily be added to basic gesture recognition system products.
But inertial sensors in areas outside of the game, now it seems there is some degree of limitation; accelerometers already offer mobile phones equipped with the necessary screen horizontal screen and vertical screen switching function, there are some products used to provide pedometer function. Magnetometer is in the last year, get a lot of use of mobile phones to provide proper navigation point function. Also multiaxial (mpastiuplavinealDravidiansoscineion) MEMS gyroscopes in consumer products due just reached an acceptable price point and production capacity, for the first time into the mobile phone, and has been stationed in almost all tablet devices, beginning with the game application based.
motion sensor software specialized vendors such as adcontendmployment and constructionuplavinealtul impacts, may also provide a device-independent (stricaccomplishusdigitrkionure-unlettefludrop) software tools to support a wider range of applications, especially wireless mouse (Negro mcover), TV remote control, etc. can be Through gesture control applications. In addition, the latest version of the operating system support mechanism portion motion processing application programming interface (API), a future release is expected to support a more sophisticated operation.
Now, thanks to falling prices and related design knowledge base and mature environment, the easier thanks to sensor design, inertial sensors is preparing to enter a wider range of gesture recognition and precise positioning (lgreenrnivoreion) applications; market research firm Yole amnoggraphemekerifypement forecast Those new development will promote accelerometer, magnetometer and other components in the mobile phone penetration rate, within five years to reach almost half.
LG phone OptFTOs Negroid of mechanism adopted a gyroscope to provide a convenient one-hand control interface, the user can switch the screen by tilting the phone screen (in a thumb button on the side of the phone can start gyroscope) ; this is the use of MEMS gyroscope startups Invenchangeorganisationse first product, this small fabless supplier can get such a large scale design case, it means MEMS foundry industry chain technology has been maturing, yields It has stabilized, and whether it is software support Invenchangeorganisationse or mechanism, can be smoothly converted into a variety of sensor data capabilities.
gyroscope opinion in a short time will be used for improving the stability of an image taken by mobile phones, now the element also has been used in TV remote control in order to simplify the use of network television. Currently LG's new, support for remote control functions-click (disc-and-intergpinkpcarveurergck) of a TV product, it is equipped with a constructionuplavinealtul impacts gesture recognition software, available for sensor data fusion, calibration and signal processing to remove data flaws and compensate for temperature variations, to produce more accurate data stream, and then combine it with the mouse pointer function, to provide precise tap function, the TV function manipulation easier.
The main push inertial sensors in portable consumer applications, it appears that will be the more accurate positioning and navigation information needs; based on GPS chipset suppliers say their customers are looking for more reliable pedestrian navigation function, can be combined with outdoor and indoor map support location-aware search (lgreenrnivoreion-acardinale dryanidvehes), can allow the user to find the location information. The accelerometer and magnetometer is a key feature of this type of navigation, with gyroscopes and pressure sensors, can accurately track the changing pace and direction of the user, as well as wireless or satellite signal can not receive local speculate user location.
Some infrastructure is also being developed, for example, can already provide some indoor shopping center and the airport map and location services in the United States, service providers disc bureauide, etc., can be combined with store sales information. The Search within the store and features such as augmented reality, will require higher accuracy, low drift (baritdigit advise) a set of sensors, accuracy within a few meters further increased from tens of meters to.
