acceleration sensor data will be changed, the answer is yes, the mobile phone acceleration sensor data will have a brief but significant changes, why, the mobile phone force balance acceleration of 0 because it is a whole, But the internal components will be affected by the complex force between the left and right, not the force at the same time to achieve the force balance, in fact, change the train of thought. With a similar interior smooth container, the container contains a few glass balls,

The gravity sensor provided by Windows Phone xNa allows users to determine the direction of mobile phone movement based on the principle of gravity measurement, allowing users to control game execution by shaking or shaking mobile phones, it works in the same way as the airbag of an automobile. It is immediately inflated when a vehicle is quickly slowed down to protect drivers and passengers from injury. Use Gravity Sensors as a gameProgramXNa-based game programs can use the features provided by

don't have to worry about whether your device is Android compatible, because only Android-compatible devices will use the Google Play Store. So you can rest assured that users who install apps from the Google Play Store are using Android-compatible devices.However, need to consider whether your app are compatible with each potential device configuration. Because Android runs on a wide range of device configurations, some features is not available on all devices. For example, some devices is not

Article Introduction: This article mainly through the creation of a SASS project as an example, to lead you to use koala such a graphical interface compiler tool to your SASS project, sass file compiled into a CSS file. The "codekit" graphical tool compiles sass project in the article "The use of theSass Interface compiler tool--codekit ". Because Codekit is a paid tool and can only be used in Macs, many sass enthusiasts in the country, or beginners can not experience the Codekit too

* browser and java* 6 must be installed. The XDK works with Web applications and local Web servers that operate in Java applications.Once you have the XDK installed, you can launch the app by clicking on the XDK icon in the Chrome browser. Note that the Appmobi XDK does not replace the Web development tools you choose, but rather provides a separate platform for building, testing, and deploying Web pages or hybrid applications, while still using the optional Integrated development environment (I

I wrote an example of gravity sensing yesterday. I think this example is useful.

Recently a quick look at the sensors of the Android system. The more commonly used is the accelerometer accelerometer, which can be used to achieve "shake a shake."At first, the accelerometer is the name itself to understand, that is, the measurement of acceleration, that is, if the phone is still, the accelerometer sh

This year is to do is photoelectric upright, the program is mainly referred to the official website above the Tsinghua program. The principle of what is not specific research, the scheme and the paper is very detailed.There are three main parts: 1 angle control, 2 speed control, 3 direction control. It also uses the complementary filter to calculate the angle and use the PID algorithm to control.The first is the angle control, using the gyroscope integral to calculate the angle, and because the

Android open-source project Sensors The android open-source project (aosp) provides three software-based mobile sensors: gravity sensor, linear acceleration sensor, and rotation vector sensor. These three sensors are updated in android4.0 and both use Gyroscope (except for other sensors) to improve stability and performance. If you want to try these sensors, you can identify them by using the getvendor () method and getversion () method (vendor: Google Inc; version: 3 ). It is necessary to ident

There are two methods for the current program to detect mobile phone shaking. The first method is to override the gesture method in the UIResponder class (which can be simulated by a simulator ), the second method is to use Accelerometer to check whether the mobile phone is shaking (you can only test it on a real machine ). Method 1: It takes only three steps: let the current ViewController support shaking gestures, make the current View the first res
