Location sensors

6.1 INTRODUCTION
6.1.1 Spatial location
This chapter describes the sensors that capture the real-time location of any object to
know its position and (or) to follow its path. These motor interfaces are indispensable
in virtual reality techniques. In this field, the object to be located is often a body part,
the entire body or an object handled by the user. These devices, motor interfaces for
virtual reality, can also be used in other sectors like metrology, robotics, etc. When
they are used in virtual reality, we call them “trackers’’. These sensors are designed to
measure only the spatial position ...
