designed to measure the rotating motion of a device. Better at the movements of devices. However, the location of the device cannot be determined.The advantage of a accelerometer is to measure the force of a device. Better at the movement of devices than external reference objects (such as the ground. However, it is not accurate to measure the placement posture of the device relative to the ground.The strength of a magnetic meter lies in positioning

A lot of sensors are built into the phone, such as: light sensor, humidity sensor, temperature sensor, distance sensor, etc.The development of sensor-related things must use the real machineIn the spiral and accelerometer all two ways push and pull, push way is always detected, pulling the way is required to obtain the detection value/*Steps to use the accelerometer push:1.

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 to be implemented is sensoreventlistener, whi

Afish-finder is a device used by anglers Tofindfish in a. If Thefish-finderfinds Afish, it would sound an alarm. It uses depth readings to determine whether to sound a alarm. For our purposes, Thefish-finder'll decide that Afish is swimming past if:
Fish-finder is a magical device for anglers who use the area in nursing fishing. If a f-f finds a fish, he will sound an alarm. It uses the depth of the fish to decide whether to ring th
Example 2. Collecting satellite readingsAs shown in Example 1, the sequence allows unique values to be generated across multiple tables. Sequences also allow for the automatic generation of their values for multiple columns in a table.For this example, consider a orbiting satellite orbiting a planet or moon. This particular satellite SAT1 is designed to capture data readings from 16 different points on its orbit. The table that collects the data has

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
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
Study on the feasibility of gravity induction gameA. Gravity sensing components in mobile phonesMany people know that the mobile phone has the function of gravity sensor, but what is gravity sensor is not very understanding. Gravity sensor is not a camera, people know how many pixels, not touch screen, people know whether it is capacitive screen or resistive screen, gravity sensor like shrouded in the fog of the valley, it is difficult to explore. The gravity sensing components are described in

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
