旋转矢量传感器

Question

I want to know how to use rotation vector sensor in android development. I couldn't understand how to do this from the android developer official website. I need any book or video that explains this topic for the beginners.

Answer 1

A good introduction outlining the various sensors under android is the devolopers site . After this you could go on reading about position , motion or environmental sensors, depending on what you want. Pictures of the two coordinate systems related by the rotation vector:

• smartphone-fixed frame
• android-refrence frame

The code examples are basic, so in case you find it hard to comprehend, there might be lacking knowledge in Java itself or the mechanical background. The Java beginners guide could be a starting point or tutorialspoint to go straight for the sensors. More about mechanics on wikipedia
