SHAKE TO CHANGE

WHAT

Rapidly moving an object back and forth changes its state or triggers an action.

USE WHEN

Use Shake to Change for very simple actions that have little nuance, usually with objects that can be held in the hand easily.

WHY

This is a simple action that most people can perform. Also, it has an element of fun and delight to it.

HOW

Shake to Change requires an accelerometer to detect motion. When enough vibration is detected, the action triggers.
