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.

5. Inside a Mouse…
SPACE MOUSE
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:

6. 1.BALL …
SPACE MOUSE
A ball inside the mouse touches the desktop and rolls
when the mouse moves.
Fig .2 The exposed portion of the ball touches the desktop

7. 2.ROLLERS...
SPACE MOUSE
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

8. 3.DISK…
SPACE MOUSE
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. The following image shows the disk:

edge

9. 4. SENSOR…
SPACE MOUSE
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
Dept. of ISE,BRCE 9

10. 5.PROCESSING CHIP…
SPACE MOUSE
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

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

19. Origin of Space Mouse…
At the end of the seventies, the
DLR (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.

20. Cont...
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.

25. CONCLUSION
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.
