3. Introduction: What is Space Mouse?
 Space Mouse is a professional 3D controller
designed for manipulating objects in a 3D
environment.
It has different modes of operation in which it can
also be used as a two-dimensional mouse.
It serves as a man-machine interface , enables the
user to intuitively zoom, pan and rotate models.
It can control 3D cameras at different angels to
position and view the objects.

4. Inside a Mouse…
Mice first broke onto the public stage with the introduction
of the Apple Macintosh in 1984, and since then they have
helped to completely redefine the way we use computers.
The main goal of any mouse is to translate the motion of your
hand into signals that the computer can use. Almost all mice
today do the translation using five components:

5. 1.BALL …
A ball inside the mouse touches the desktop and rolls
when the mouse moves.

6. 2.ROLLERS...
Two rollers inside the mouse touch the ball. One of the
rollers is oriented so that it detects motion in the X direction,
and the other is oriented 90 degrees to the first roller so it
detects motion in the Y direction.
Fig.3 The above image shows the two white rollers on mouse that touch
the ball and detect X and Y motion

7. The rollers each connect to a shaft, and the shaft spins a
disk with holes in it. When roller rolls, its shaft and disk
spin. This disk has 36 holes around its outer edge
3.DISK…

8. 4. SENSOR…
On either side of the disk there is an infrared LED and an
infrared sensor. The holes in the disk break the beam of light
coming from the LED so that the infrared sensor sees pulses of
light.
Fig.5 There is an infrared LED (clear) on one side of the disk and an infrared
sensor (red) on the other

9. 5.PROCESSING CHIP…
An on-board processor chip reads the pulses from the infrared
sensors and turns them into binary data that the computer can
understand. The chip sends the binary data
to the computer through the mouse's cord.
You can also see the two buttons
that detect clicks (on either side
of the wire connector).

and turns them into bytes sent to the computer

10. 10
In this optomechanical
arrangement , the disk
moves mechanically, and an
optical system counts
pulses of light.
On this mouse,the ball is 21
mm in diameter. The roller
is 7mm in diameter.the
encoding disk has 36
holes.So if the mouse moves
25.4 mm (1 inch)
The encoder chip detects 41
pulses of light

11. Features…
Ease of use of manipulating objects in 3D
applications.
15 programmable buttons adjust sensitivity and
motion control to the users preference.
 Fingertip operation for maximum precision and
performance.
Natural hand position (resting on table) .
Calibration free sensor technology for high
precision and unique reliability.

12. Cont……
Settings to adjust sensitivity and motion control to the
users preference.
Any computer whose graphics power allows to update at
least 5 frames per second of the designed scenery, and
which has a standard RS232 interface, can make use of the
full potential of Magellan spacemouse.

21. Origin of Space Mouse…
At the end of the seventies, the
DLR-(Deutsches zenturum far
Luft und Raumfahrt ) German
Aerospace Research
Establishment institute for
robotics and system dynamics
started research on devices for
the 6-dof control of robot
grippers in Cartesian space.
 It took until 1985 for the DLR's
developer group to succeed in
designing a much cheaper optical
measuring system.

25. The basic principle behind its construction was
“MECHATRONICS ENGINEERING”.
Mechatronics is concerned with the design automation
and operational performance of electromechanical
systems.
Mechatronics is a blending of Mechanical engineering,
Electronics engineering and Computing.

26. FUTURE SCOPE
 Magellan's predecessor, DLR's control ball, was a
key element of the first real robot in space,
ROTEX- (3), which was launched in April 93.
 A most intuitive controlling device would be a
system that can be instructed by watching and
imitating the human user, using the hand as the
major controlling element. This would be a very
comfortable interface that allows the user to move
a robot system in the most natural way. This is
called the visual space mouse.
26

27. Advantages…
Drawing times is reduced by 20%-30% increasing overall
productivity.
Going back and forth to the menu is eliminated.
Natural hand position (resting on table) .
Allows the user to move a robot system in the
most natural way.

29. Disadvantages…
Too expensive (nearly $8000 earlier now reduced
to about $3000 even though manufacturing cost is
less than $1000).
works only if RS232 interface is provided

31. The features of a space mouse are not only
applicable to the graphic simulation and 3D
objects but they will strongly change the whole
world of manufacturing and constructing
technology.
It is also applicable to other areas of science
like chemistry ,biology and also entertainment.
No other technology can beat the SPACE
MOUSE in its simplicity and yet high precision.
