Because 3D input devices are mainly used for special applications, they
will not be described here in detail. Nevertheless, some devices will be
- A device which provides three translational and three
rotational degrees of freedom (DOFs). It can be used in CAD and robotic
applications, for instance. Typical representatives are the SPACEMASTER and the SPACEMOUSE (see also
section 3.4.4 ).
- Data glove
- The data glove is a glove which is equipped with a
tracking sensor. The (unconstrained) movements of the user's hand in 3D
space are sensed and used to control the application. Data gloves are
most often used in VR applications. They might be equipped with tactile
feedback capabilities, see the Teletact on page 2.2.4 .
- The tracker is very similar to the data glove, but instead
of a glove it has to be held with the hand. Therefore, no feedback can be
applied. The most popular one is the PolhemusTracker which is used for in
VR applications. Both, data glove and tracker, are often used in
combination with head-mounted displays (HMDs).
