accelerometer readings

Android context data needs to be used recently. Context data needs to be obtained from a wide range of Android sensors. Before that, we should first understand the available Android sensors, and what are their functions? 1. an accelerometer senses the current acceleration of a mobile phone. It can be used to change the Instantaneous Acceleration of the mobile phone. In addition, by measuring the acceleration caused by gravity, you can calculate the ti

dealTouches: touches]; } The layer touch input is now mentioned here. Other advanced usage will be mentioned later. 2. Receive the accelerator Input By default, CCLayer does not receive the accelerator input. You must set isAccelerometerEnabled to YES explicitly. [Java]View plaincopy Self. isAccelerometerEnabled = YES; When isAccelerometerEnabled is set to YES, the corresponding method of the layer is called to process the accelerator input: This is the method defined in the UIAccelero

This article translated from: http://developer.android.com/guide/topics/sensors/sensors_overview.html Most Android devices have built-in sensors for measuring motion, direction, and various environmental conditions. These sensors provide raw data with high precision and accuracy that can be used to monitor the movement and position of a device in three dimensions, or to monitor changes in the environment around the device. For example, a game may have to read tracks from Gravity Sensors to dedu

For an accelerometer, we only need to know its three-axis data, while the android upper layer only needs data in a data structure. 1. About the Linux driver layer The driver registers the input device, reads the three-axis data in the sensor register through the I2C interface, and reports the three data. 2. About the Android hardware abstraction layer There is a sensors. h header file under hardware \ libhardware \ include \ hardware. Fill in a dat

support in UI. Adds smooth interial mouse scrolling. Adds keyboard event handling code that was missed on some UI containers and controls. Adds game accelerometer and gyro improvements. Adds Xbox 360 controller support to MacOS X. Adds renderstate Enum for supporting cull side definition for front, back and front-back culling. Adds a Lua function "convert (object, classname)" that will convert a gameplay userdata object to another class type by

iOS Learning Note (3)-screen rotationfirst, the screen rotation mechanism:iOS uses the accelerometer to determine the current device orientation and screen rotation. When the accelerometer detects a direction change, the screen rotation process is as follows:1. When the device rotates, the system receives the rotation event.2. The system notifies the current main window by appdelegate the rotation event.3.

What is the usual event in 1.ios? Touch events, accelerometer events, remote control events2. What is a responder object? Inherit the object of Uiresponds we call it the Responder object uiapplication, Uiviewcontroller, UIView inherit? From Uiresponder so they are both responder objects that can receive and handle events3. Why is it that inheriting uiresponder can handle events? Because the Uiresponder internally provides the following methods to hand

Getdefaultsensor (int type) returns the type of the specified sensor object, such as sensors accelsensor = Sensormanager.getdefaultsensor (sensor.type_ ACCELEROMETER); Gets the Accelerometer object Registerlistener (sensorlistener Listener, int sensors, int rate) Register Sensor listener Events Step two: Get the Sensor objectSensor accelsensor = Sensormanager.getdefaultsensor (Sensor.type_acce

, so there is no way to mount them. The reason for this error is because make will check each kconfig file, no option will automatically rate, so we also need to modify the Kconfig file. 5.

point to the center without my extra calculations. Another advantage of using matrices is that I can use the range and coordinates directly without excessive numerical calculations. After I finished the desktop side of the effect I suddenly realized that on the mobile side (even the smart phone) is not the same effect, because the mobile end has no mouse events. I decided to test the JS event "Devicemotion", which allowed me to determine the status of the
