unity accelerometer

BIN CHEN May 23, 2012, Evening 10:34 12 Some mobile phone players and enthusiasts are interested in the components of some mobile phones and even want to know how they work. Now, both mobile phones and tablets are basically built-in acceleration sensors to identify the direction of the device's rotation. Bill Hammack, an engineer from Illinois University, briefed us on how this acceleration sensor works and is not a tedious sermon, but an animated film to help explain it.Bill Hammack used Andr

First, the conceptAccelerometer: Measures the acceleration in three directions of the x, Y, Z axis by sensing the total amount of inertial forces in a particular direction.Gyroscope: Measures the value of rotation around the x, Y, and z three directions. Feature: If you keep your phone flat while rotating it, the accelerometer value will not change, at which point the rotation value around the z axis is changed. Rotating the device clockwise generates

Cocos2d-x accelerometer instance: moving ball, cocos2d-x AccelerationNext we will use an example to describe how to access the accelerometer through layer-based accelerometer events. As shown in this example, there is a ball in the scene. When we place the mobile device horizontally, the screen is up, and then shake the mobile device left and right to change the

One accelerometer principleThe 1.1 accelerometer consists of a MEMS sensor and a signal processing chip.1.2 MEMS Accelerometer Working principleIt is composed of upper capacitance, medium capacitance plate (movable), lower capacitance plate, etc., when the acceleration reaches a certain value, the medium capacitance plate will move, and the distance from the uppe

Because the data acquisition station is basically installed in the field or the roof, the installation location and vibration have certain influence on the accuracy of the test data. So want to have a position state data, just found Kylin made on the ADXL345, such a digital output acceleration sensor. As shown in the red box:1 , ADXL345 OverviewADXL345 is a 3-axis, digital output accelerometer based on Imems technology from Adi. The characteristics of

First, the principle of introduction:The function of shaking in Android phone is already very common, recently contacted this function, the principle is very simple: using accelerometer, when shaking the phone, listen to the acceleration in all directions of change, when the acceleration value exceeds the set sensitivity, then trigger shake function.Second, the use of the class:SensormanagerSensoreventlistenerThird, the function realization:1, shake a

Android: Accelerometer Welcome to the sensor world.The sensor literally refers to the instrument that transmits the feeling. What is the feeling?Visual, auditory, taste, touch, and smell.Some people say that the existence and development of sensors allow objects to have the senses such as touch, taste, and smell, so that objects can gradually become active.At present, Android devices have been integrated into dozens of sensors, and we usually have acc

Acceleration Sensor Accelerometer The Android system supports powerful management services for sensors. The steps for developing sensor applications are as follows: (1) Call the getSystemService (Context. SENSOR_SERVICE) method of Context to obtain the Sensor Manager object. The SensorManager object represents the system's Sensor management service. (2) Call the getdefasensensor (int type) method of SensorManager to obtain the sensor of the specified

Symbol Description:T: The time between the measured value and the last measured value;RESTX (n-1), Resty (n-1), Restz (n-1): The optimal value vector for the position of the n-1 time;GRATEXZ (n), Grateyz (n): The value of the gyroscope, the value of the nth time after filtering alone.GRx (n), GRy (n), GRz (n): position vector fused to gyroscopeRAx (n), RAy (n), RAz (n): The nth-time vector of the measured value of the accelerometer;RESTX (n), Resty (n

Next we will use an example to describe how to access the accelerometer through layer-based accelerometer events. As shown in this example, there is a ball in the scene. When we place the mobile device horizontally, the screen is up, and then shake the mobile device left and right to change the position of the ball. Next let's take a look at the specific program code. First, let's take a look at the hellow

The example in this section is a tilt angle measurement application that accurately measures the tilt angle of your phone and the horizontal plane, using the acceleration sensor inside the Android sensor. The physical meaning represented by the various values of the accelerometer, coupled with a very simple algorithm, can be used to measure the tilt angle.The angle value is displayed exactly as the phone tilts and the effectNot much nonsense to say di

Recently engaged in a project related to the accelerometer, so contact with more sensors, now write a summary, to prevent the later and I like to walk so many detours.The first thing to see is the pin graph, if the driver should not first troubleshoot the hardware problem:SPI Connection methodIIc Connection method We then focus on a few registers: sensor Name (read/write) Register number function Chipid (R) 0x0

The coordinate system of the Android sensor is not the same as its 2D design, with coordinate systems such as:Once the sensor listener is registered with the Sensormanager object, an object of sensorevent can be obtained within the Onsensorchanged method.The Sensorevent object has an important member variable public final float[] values, which are defined as follows:Public final float[] valuesThe length and contents of the values array depends on which sensor type is being monitoredIf the regist
