What is Space Mouse?SPACE MOUSEDept. of ISE,BRCE 3 4. SPACE MOUSEIntroduction: What is Space Mouse? Space Mouse is a professional 3D controllerdesigned for manipulating objects in a 3Denvironment.It has different modes of operation in which it canalso be used as a two-dimensional mouse.It serves as a man-machine interface , enables theuser to intuitively zoom, pan and rotate models.It can control 3D cameras at different angels toposition and view the objects.Dept. of ISE,BRCE 4 5. Inside a MouseSPACE MOUSEThe main goal of any mouse is to translate the motion ofyour hand into signals that the computer can use. Almost allmice today do the translation using five components:Fig.1 The guts of a mouseDept. of ISE,BRCE 5 6. 1.BALL SPACE MOUSEA ball inside the mouse touches the desktop and rollswhen the mouse moves.Fig .2 The exposed portion of the ball touches the desktopDept. of ISE,BRCE 6 7. 2.ROLLERS...SPACE MOUSETwo rollers inside the mouse touch the ball. One of therollers is oriented so that it detects motion in the X direction,and the other is oriented 90 degrees to the first roller so itdetects motion in the Y direction.Fig.3 The above image shows the two white rollers on mouse that touchthe ball and detect X and Y motionDept. of ISE,BRCE 7 8. 3.DISKSPACE MOUSEThe rollers each connect to a shaft, and the shaft spins adisk with holes in it. When roller rolls, its shaft and diskspin. The following image shows the disk:Fig.4 A typical optical encoding disk: This disk has 36 holes around its outeredgeDept. of ISE,BRCE 8 9. 4. SENSORSPACE MOUSEOn either side of the disk there is an infrared LED and aninfrared sensor. The holes in the disk break the beam of lightcoming from the LED so that the infrared sensor sees pulses oflight.Fig.5 There is an infrared LED (clear) on one side of the disk and an infraredsensor (red) on the otherDept. of ISE,BRCE 9 10. 5.PROCESSING CHIPSPACE MOUSEAn on-board processor chip reads the pulses from the infraredsensors and turns them into binary data that the computer canunderstand. The chip sends the binary datato the computer through the mouse's cord.You can also see the two buttonsthat detect clicks (on either sideof the wire connector).Fig.6 A small processor that reads the pulses coming from the infrared sensorsand turns them into bytes sent to the computerDept. of ISE,BRCE 10 11. Features Ease of use of manipulating objects in 3Dapplications.SPACE MOUSE Nine programmable buttons adjust sensitivity andmotion control to the users preference. Fingertip operation for maximum precision andperformance. Calibration free sensor technology for high precisionand unique reliability. Natural hand position (resting on table) eliminatesfatigue.Dept. of ISE,BRCE 11 12.

Origin of Space MouseAt the end of the seventies, theDLR (German AerospaceResearch Establishment) institutefor robotics and system dynamicsstarted research on devices forthe 6-dof control of robotgrippers in Cartesian space. It took until 1985 for the DLR'sdeveloper group to succeed indesigning a much cheaper opticalmeasuring system.SPACE MOUSEEg: JARVISDept. of ISE,BRCE 19 20.
