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

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

Well, thanks to the recent development requirements for smart hardware, so the recent days to share the blog is roughly linked to intelligent hardware, like a piece of Bluetooth sharing, I believe that many readers have seen, then today I bring you the knowledge of the Android sensor introduction and use of methods, for the use of sensors , different versions of the Android phone may have larger hardware differences, but same, this article will be through the most common sensors, the infiltratio

usually obtain data by measuring attributes of special environments, such as changes in gravity acceleration, geomagnetic intensity, or azimuth angle. Software-based sensors do not rely on physical devices, though they mimic hardware-based sensors. Software-based sensors usually obtain data through one or more hardware sensors, and sometimes call virtual sensors or artificial sensors, linear accelerometer and gravity sensor are examples of software-b

1. Cell phone's coordinate chart The Core Motion Motion Manager lets you specify how often (in seconds) to receive updates from the accelerometer and gyroscope, and lets you specify a handler block directly (handle block), which executes the handler block whenever the update is ready. The actual acceleration is broken down into two parts in core motion: Gravity and Useracceleration. Gravity represents gravity 1g in the distribution of equipment, us
