Introduction

The Kivy framework is able to handle most common types of input and actions such as mouse, touchscreen, accelerometer, and gyroscope that will be reviewed in this chapter. It handles the native multitouch protocols on the following platforms: Tuio, WM_Touch, MacMultitouchSupport, MT Protocol A/B, and Android.

The class of all input events is motion event. It generates two kinds of events; one of them is touch events—a motion event that contains at least an x and y position. All the touch events are dispatched across the widget tree. The no-touch events are the rest. The accelerometer is a continuous event, without position. It never starts or stops. These events are not dispatched across the widget tree.
