# Understand Accuracy

## How Moasure Works

Moving slowly might seem like it would increase accuracy. However, Moasure uses advanced motion sensors that continuously measure during movement and records data every time the device stops moving. 

With motion-based measuring, error increases over time, not over distance so quicker movements lead to more accurate results.

Using advanced inertial sensors, accelerometers, and gyros, Moasure captures X, Y, and Z (elevation) coordinates when the device is moved from one place to another. 

To ensure optimal accuracy, it’s important to pause at regular intervals to record data points, since measurement error accumulates over time, not over distance. Additionally, gently placing the device is crucial to avoid shocking the sensors and to maintain precise measurements.

### Measurement Data

When placed gently and kept completely still, Moasure calculates and records a point with X, Y, and Z values.

The first point recorded in a measurement is always the 0 point (X:0, Y:0, Z:0). 

Subsequent X, Y and Z (elevation) coordinates are calculated and displayed relative to this origin.

Advanced algorithms compute the overall linear distance and area based on these points.

## How to Maximise Measurement Accuracy

To achieve maximum accuracy in motion-based measurements, follow these three key techniques:

1. **Pace**: Walk at a fast pace between measurement (pause) points.
2. **Placement**: Place the Moasure device down quickly and gently without hovering.
3. **Rotation**: Rotate the device gradually, not abruptly, to avoid shocking the sensors.

By adhering to these techniques, you can ensure the highest possible accuracy in your Moasure measurements.
