situation.It's obvious that the coordinates are flipped.While rotating the second 90 degrees, the coordinate system does not flip.Then, when the third 90 degree is rotated, the coordinate system has been flipped again.When the last rotation is 90 degrees, the coordinate system does not flip.At this point, we can directly observe that the machine (cell phone) has turned over over the first 90 degrees and th

Do gravity induction friends may be able to use, I write up here to sometimes forget that I can also look at, because I do not think that learning things can be a lifetime remember very well, so sometimes it is convenient for their own line, to write their own blog, haha.To do Unity's gravity-sensing game, we need to use a parameter like this: Input.acceleration, which is an Input attribute of type VECTORS3, which has three parameters in X, Y, Z. Next, I'm going to put a picture of me, so everyo

The phone sensor detects all the sensors available on the Android phone and graphically shows how they work. Cell phone sensors can also identify which sensors are supported by the phone's hardware and provide a sensing tool that plays an important role in our daily lives. T

First, the phenomenon is to call the phone, connect the phone, close the screen of the phone to the face, block p-sensor, the screen turns black, do not block p-sensor, the screen is lit up. Next let's take a look at the code process. Step 1: In the oncreate () method in th

Now there are all kinds of sensors in Android phones, such as accelerometers, gyroscopes and the like, I now use a total of nine sensors in the Vivo V3 phone:Lis3dh-accel : Tri-axis acceleration sensorTmd277x-proximity : Near distance sensorTmd277x-light : Light sensorYas533-orientation : Direction sensorYas533-pseudo-gyro : Motion sensorYas533-linear-acceleration : Linear acceleration SensorYas533-rotation-vector : rotational vector sensorYas533-grav

the right bottom of the cell phone that is placed horizontally. The x direction is the horizontal direction of the phone, rightThe y direction is the horizontal vertical direction of the cell phone, the front is positiveThe y direction is the

Motion sensors are useful for monitoring the movement of devices, such as tilt, vibration, rotation, and swing, which are the monitoring ranges of motion sensors. The movement of a device is usually a direct response to user input.All motion sensors return a value of three floating-point numbers, and for different sensors, the three values have different meanings. For example, for an accelerometer, the acceleration data for three axes is returned. For a gyroscope

In 2017, when the industry was excited about the big opportunities for the upcoming IoT industry, Gartner's latest survey poured a splash of cold water: Consumers were initially attracted by the novelty and appearance of wearables, However, nearly one-third of users are bored after a period of time and then abandon them, the smart watch deprecation rate of 29%, fitness class wearable device deprecation rate of 30%.In addition to wearable devices, smartphones and tablets are also entering a lackl
