The instructor of the fetc project proposed a new requirement. He wanted to show the user's current movement direction in the game map. If he used GPS, it was obviously unreliable, so he thought of the powerful Android sensor... Many mobile devices have built-in sensors. Android abstracts these sensors through the sensor and sensormanager classes, and these sensors can be used by Android devices. 1.

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

This paper introduces the characteristic principle and application scenario of the-LIS3DH accelerometer sensor for wearable devices. ST's LIS3DH is widely used in smart wearable products such as smart hand loops and smart step shoes.LIS3DH has two ways of working, one of which is that it has built-in algorithms to handle common scenarios such as standstill detection, motion detection, screen flipping, weigh

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 pre

I. INTRODUCTION of COREMOTION FrameworkWe know that there are some iOS apps that have special requirements, such as:1. E-Compass Compass application: Let us know the direction.2. Sport type Software: Let us know how many kilometres we run.3. Shake and shake function in social software.4. Play in the role class in the game according to the device's shaking and so on operation.In fact, they're mostly using a core motion framework in iOS.CoreMotion.framework Use the framework that iOS prov

In general, getting the location information of the phone in the Android system has the Type_orientation constant in the API, which can be obtained as the accelerometer sensor Sm.getdefaultsensor (sensor.type_ ORIENTATION); However, we do so in the latest version of the SDK will see this sentence: "Type_orientation this constant is deprecated. Use Sensormanager.getorientation () instead. "That way also expi

Recently before the improvement of the visual fixed-point algorithm, there was only one location ring, now ready to cascade a series of speed loop, but to solve the drone translation speed is still quite a headache, the online information is very small, we need to move our own brain to solve this problem.The first step is to measure the level of speed, the traditional method is GPS, I designed the UAV in the application scene of the GPS signal although there is, but not so stable, followed by th

Sensor introduction: Speaking of sensors, I believe everyone will be familiar with it. For example, an acceleration sensor is u

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 Imem

An accelerometer is a sensor that can sense the linear acceleration of a device. It is widely used in guidance and control of aviation, navigation, aerospace and weapons. There are many types of linear accelerometer. Currently, three-axis accelerometer is used in mobile devices such as IOS. It can be used to sense the

The following are several constants defined in the API that represent sensor. Int Type_accelerometer A constant describing an accelerometer sensor type. Acceleration Sensor Int Type_all A constant describing all sensor types. All Types A constant describi

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 ang

This article illustrates how Android uses the sensor sensor to get the direction of a user's movement. Share to everyone for your reference, specific as follows: Today continue to share a second important sensor, in fact, to get the direction of the things should be very simple, in the previous article to see that there is a type_orientation keyword, you can dir

in turn.1 Acceleration sensorThe accelerometer is also called G-sensor, which returns the acceleration values for the X, y, and Z axes.This value contains the effect of gravity, in units of m/s^2.Put your phone flat on the desktop, the X axis defaults to the 0,y axis default 0,z axis default 9.81.Place your phone face down on the desktop with a Z axis of-9.81.Tilt the phone to the left and the x-axis as p

The Android platform provides several sensors that can monitor the movement of devices. Two of them are hardware-based (accelerometer and gyroscope). Three sensors can be hardware-based, it can also be software-based (Gravity Sensors, linear acceleration sensors, and rotating vector sensors ). For example, some software sensor-based devices extract their data from the a
