| Activity detection can be configured as referenced or absolute. |
| When using absolute activity detection, acceleration samples are |
| compared directly to a user set threshold to determine whether |
| motion is present. In many applications, it is advantageous for |
| activity detection to be based not on an absolute threshold, |
| but on a deviation from a reference point or orientation. |
