    Operation manual for Acceleration Measurement Web App with rotation correction† without installation
    † Rotation correction: conversion from acceleration in a device-fixed coordinate system to acceleration in a stationary coordinate system (detail)
    
■ Overview
This application is an acceleration measurement web application that simultaneously acquires the acceleration generated in the device and the Euler angles of the device, and converts the acceleration in a coordinate system fixed to the device to that in a stationary coordinate system. The ability to obtain acceleration in a stationary coordinate system facilitates measurement and analysis of 2-D and 3-D motion. This is a web application that runs in a web browser and does not require installation.
