An important input source on a mobile device is the device direction. Most devices are equipped with an

Yesterday, Ti made a shock to the electronics industry, announced the latest release of Sitara am335x arm Cortex-A8 microprocessor, the bulk price of only 5 dollars, at the same time, it also launched an easy-to-use open-source hardware platform and a free software development kit at an ultra-low price of $89. Both prices can be said to have broken the current industry's gaming rules. This message was sent by Chang Xu on Weibo, attracting an exclama

Coremotion is a framework dedicated to motion, which contains two parts of accelerometers and gyroscopes, before iOS4 the accelerometer is the Uiaccelerometer class responsible for collecting data, Now generally use coremotion to deal with the acceleration process, but because Uiaccelerometer is relatively simple, the same people are used. Accelerometer is determined by three axes, the user's most common op

ObjectiveBefore someone made a mobile phone anti-theft app through the iphone's accelerometer, and it was through this anti-theft app to get Angel investment. From then on gorgeous turn, the company develops the vivid. Although this project is not very good at the end, but it is really a nice idea.Maybe you don't know, every iphone has an accelerometer built in. This allows the built-in

Transfer from http://blog.csdn.net/a345017062/article/details/6459643A gyroscope is an internal gyroscope, whose axis is always parallel to the initial direction due to the gyro effect, so that the actual direction can be calculated by deviations from the initial direction. The gyroscope in the cell phone is actually a very sophisticated chip with ultra-tiny tops inside.Accelerometers are used to detect the size and direction of the acceleration that the phone is subjected to, while the mobile p

Cclayer OverviewA game can have a lot of scenes, each scene may contain more than one layer,The layers here are generally cclayer objects. The cclayer itself has almost n

This article is from: http://ucdchina.com/snap/9797,thank you! In June 8 last year, the Great Apple company released the latest iPhone 4G, which has many hardware upgrades. For gamers, the largest "Three-Axis Gyroscope "! The first time I heard that this "Three-Axis Gyroscope" was a time ago, I occasionally found that Apple players were testing the positioning function of the iPod Touch. For details, see "location offset problem of different mobile devices ".It seems very novel-Because iPod touc

Acceleration SensorThe acceleration sensor of the mobile phone is calculated by the offset of the x, Y, z three axes.The basic API in code is mainly focused on the Accelerometer typeThe main thing is to use this type of object to capture readingchanged events to monitor the change in acceleration values.X, Y, Z acceleration sensing values1 StackPanel>2 TextBoxx:name= "Txtx"Header= "X:"/>3 TextBoxx:name= "Txty"Header= "Y:"/>4

example a delegate to the accelerator, the program example for declaring an example is as follows: UIAccelerometer *accelerometer = [UIAccelerometer sharedAccelerometer]; You can set the update rate of the instance. You can use the following program to set the update rate, which indicates that the update is performed once every 30 seconds. accelerometer.delegate = self;accelerometer.updateInterval = 1.0f / 30.0f ; After setting the delegate, you m

This paper introduces the characteristic principle and application scenario of the-LIS3DH accelerometer sensor for wearable devices. ST's LIS3DH is widely used in smart wearable products such as smart hand loops and smart step shoes.LIS3DH has two ways of working, one of which is that it has built-in algorithms to handle common scenarios such as standstill detection, motion detection, screen flipping, weightlessness, position recognition, click and do

Memsic2125 Acceleration Meter MEMSIC2125 is a two-axis accelerometer that can measure the acceleration of positive or negative 2g in two directions (g represents the gravitational acceleration). Its pin design is simple: Only two data output pins, one for the x axis and one for the Y axis. Its data output pins will output different pulse widths according to the size of the acceleration (do not know what the pulse width is please see this article). The

An accelerometer is a sensor that can sense the linear acceleration of a device. It is widely used in guidance and control of aviation, navigation, aerospace and weapons. There are many types of linear accelerometer. Currently, three-axis accelerometer is used in mobile devices such as IOS. It can be used to sense the linear acceleration changes in the direction

Recently before the improvement of the visual fixed-point algorithm, there was only one location ring, now ready to cascade a series of speed loop, but to solve the drone translation speed is still quite a headache, the online information is very small, we need to move our own brain to solve this problem.The first step is to measure the level of speed, the traditional method is GPS, I designed the UAV in the application scene of the GPS signal although there is, but not so stable, followed by th

One, the "filter" of the dataThe raw data obtained directly from the accelerometer is often not used directly, but some disturbing data needs to be removed, a process called "filtering". The word "filter" is derived from the process of radio signal processing in radio technology. In fact they are the same from the mathematical point of view, they are some kind of sampling signal, this "filtering" process is very complex, to achieve "filter" by Fourier

I. INTRODUCTION of COREMOTION FrameworkWe know that there are some iOS apps that have special requirements, such as:1. E-Compass Compass application: Let us know the direction.2. Sport type Software: Let us know how many kilometres we run.3. Shake and shake function in social software.4. Play in the role class in the game according to the device's shaking and so on operation.In fact, they're mostly using a core motion framework in iOS.CoreMotion.framework Use the framework that iOS prov
