## Introduction

Contactable component is the component with which ContactDetection interacts. Contactable component acts as a View as it only exposes properties and events that are safe to be accessed by any other object in the scene. However, it is not an HPTK module as it has no business logic or behaviour (Controller) and, therefore, it does not need variables to control that behaviour (Model).

ContactableView requires to be attached to a Pheasy object.
