Introduction to Magellan/SPACE MOUSE

Magellan/SPACE MOUSE is a 3D input device
that is used to control the position and
orientation of 3D graphical objects in virtual
space. The device controls three translational
degrees of freedom (X, Y and Z) and three
rotational degrees of freedom (A, B and C).
How Magellan/SPACE MOUSE Controls
Six Degrees of Freedom
Moving the onscreen object is as easy as
moving the Magellan/SPACE MOUSE cap. Shift
the cap right or left to move the onscreen
object horizontally through space. Pull the cap
up or press it down to move the object
vertically through space. Pull the cap toward
the user or press it away to zoom in and out.
Rotate the cap about the desired axis to rotate
the onscreen object.
Note that the values input by Magellan/SPACE
MOUSE are not interpreted as absolute
position commands but as velocity commands.
When the cap is displaced translationally or
rotationally by a constant amount (a distance
measurement), the graphical object is
assigned a continuous speed in the same
direction (a velocity measurement). The
magnitude of the cap's displacement
determines the magnitude of the onscreen
object's velocity.
Two Hands for Intuitive Control
Magellan/SPACE MOUSE allows for
simultaneous control of six degrees of freedom
with only one hand. When used in conjunction
with a 3D CAD application, it takes over the
functions of the viewing and supply hand (e.g.
for a right-handed person this is the left hand).
The working hand (e.g. the right hand)
operates the conventional 2D mouse. This
corresponds to the natural way of working
with real objects and therefore supports
intuitive creativity when generating and
manipulating 3D objects in a CAD application.
How to Optimally Handle Magellan/
SPACE MOUSE
Spread three or four fingertips around the cap
and gently shift and twist it. Apply only light
fingertip pressure to the cap. DO NOT grasp
the entire cap in your hand. It does not matter
whether the right or left hand is used. No
shoulder or wrist movement is necessary. The
ergonomic design allows the hand to rest on
the device without fatigue.
Displacement Range
The cap may be shifted up to ±1.5 mm in the
translational directions. The cap may be
rotated up to ±4 degrees about the rotational
axes.
Magellan/SPACE MOUSE Measurement
System
The cap movements are measured inside the
cap by a worldwide-patented, optoelectronic
measuring system. The cap is suspended by
springs and always returns to its initial
position.
