accelerometer compass

Since Andorid does not recommend the use of conventional directional sensors, it is recommended to use accelerometers and geomagnetic sensors to construct the data of the direction sensor, in fact the rotation angle of the z axis is the code example

iOS New Accelerometer Event"iOS New Accelerometer event "1, iOS5.0 before, you can use Uiacceleration to monitor the accelerometer event.2, after the Bug iOS5.0, Uiaccelerometerdelegate has been depreacated, as follows:　　Deprecated is not to say, but it means that in the future version will be deleted, so if you do not want to update knowledge, use Uiacceleromete

Cocos2d-x event distribution mechanism-accelerometer event monitoring, cocos2d-x Accelerometer Event monitoring mechanism In the previous article introduced the cocos2d-x touch event mechanism, this to introduce the next game is also often used in the accelerator events, these are the game is often used. An important input source on a mobile device is the device direction. Most devices are equipped with an

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

The compass module. The path of the compass import module. Compass Core ModuleReset: resets the CSS module. @import "compass/reset" Layout: Control of page Layout @import "compass/layout" Only these two modules need to be explicitly specified for introduction@ Import "

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

Use the Compass method in Vue, and use the compass method in vue. Motivation After a long delay, I finally made up my mind to write my own personal websites. Not only do I have to look so cool, but I also need to be OK with technology, so take this opportunity to exercise your unfamiliar technologies. The website plans to use Vue as the front-end framework, and Css uses Sass for writing. However, it suddenl

Reset can reset the default HTML style of the browser, because the parsing of some elements varies greatly from browser to browser. You can reset the style to make style browser compatibility easier. Easy to use @ Import "Compass/RESET" Layout has several common layout functions, which I think are quite useful. Others are used to write components that are very commonly used.Sticky footer This module provides a tool to layout your footer and stick it t

Compass module ---- Helpers, compass ---- helpers Color Stops: when using the CSS3 gradient attribute to generate an image, in addition to declaring the starting point and ending point of the gradient line, we also declare the Color values of some intermediate points, which we call Color Stops. Add the current vertex position to a color value. Color Stops helper function automatically calculates and outputs

This article mainly explains the content of compass, it is well known that compass is a SASS tool library, if the sass do not know the students can be sass and Compass Sass Chapter Sass itself is just a "CSS preprocessor", compass on its basis, Encapsulates a range of modules and templates to complement the sass functi

Source Address: http://www.geek-workshop.com/thread-1695-1-1.htmlThis post is translated from the IMU (accelerometer and Gyroscope devices) guide used in embedded applications.This article mainly introduces the mathematical models and basic algorithms of accelerometers and gyroscopes, and how to fuse the two, focusing on the discussion of algorithms and ideas.IntroductionThe purpose of this guide is to introduce inertial MEMS sensors, especially accel

Compass (Compass) is a custom view that inherits the view class, overriding the bounds (onmeasure) and content (OnDraw) of the views; As shown in figure: The following is the specific design of the compass: 1. Create Compassview class, compass view Location: Java->package->compassview Package Mzx.spike.compass.

The following are all converted from the android game programming entry-level classic. For more information, see the source. An interesting input method in the game is the accelerator. All Android devices require a 3D accelerator. Also, the compass function can sense the magnetic field direction and the mobile phone pitch angle. To obtain the accelerometer information, we register a listener. The interface

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

I haven't updated my blog for a long time. I don't want to write, don't want to get it, and I'm lazy. Today we will introduce the compass. Compass Obtain the current orientation of the device. The compass is a sensor that detects the direction or orientation of the device. The measurement unit is degree, and the value ranges from 0 degrees to 359.99 degrees

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

Final:Cocos2d-x, the inheritance structure of layer layers:As you can see from the image above:several direct sub-categories of emphasis are: Control, ScrollView, Menu, Layercolorwhere Layercolor can make a layer color the subclass of control, which is all the classes that interact with the user, such as: button, slider, etc.0. 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
