Simulation 3D Space Mouse

Process input from space mouse device

Renamed from Space Mouse Input in R2025a

Description

A space mouse is a device similar to a joystick in purpose, but it also provides movement control with six degrees of freedom. This block reads the status of the space mouse and provides some commonly used transformations of the input. The Simulation 3D Space Mouse block supports current models of 3D navigation devices manufactured by 3Dconnexion (https://www.3dconnexion.com).

Ports

Output

Translation — Status of object translation

1 or true | 0 or false

Status of object translation, returned as 0 or false if not pressed and 1 or true if pressed.

Data Types: Boolean

Rotation — Status of object rotation

1 or true | 0 or false

Status of object rotation, returned as 0 or false if not pressed and 1 or true if pressed.

Data Types: Boolean

Buttons — Status of button

1 or true | 0 or false

Status of button, returned as 0 or false if not pressed and 1 or true if pressed.

Data Types: Boolean

Parameters

Port — Serial port where mouse is connected

COM1 (default) | COM2 | COM3 | COM4 | USB1 | USB2 | USB3 | USB4

Serial port to which the space mouse is connected. Possible values are USB1...USB4 and COM1...COM4.

Output type — Type of output

Speed (default) | Position | Viewpoint coordinates

Specify how the inputs from the device are transformed:

• Speed — No transformations are done. Outputs are translation and rotation speeds.

• Position — Translations and rotations are integrated. Outputs are position and orientation in the form of roll/pitch/yaw angles.

• Viewpoint coordinates — Translations and rotations are integrated. Outputs are position and orientation in the form of an axis and an angle. You can use these values as viewpoint coordinates in a virtual world.

Dominant mode — Option to accept only prevailing movement and rotation

off (default) | on

If this check box is selected, the mouse accepts only the prevailing movement and rotation and ignores the others. This mode can be useful for beginners using Simulation 3D Space Mouse block.

Disable position movement — Option to fix rotations at initial values

off (default) | on

Select this check box to fix the rotations at initial values, allowing you to change positions only.

Disable rotation movement — Option to fix positions at initial values

off (default) | on

Select this check box to fix the positions at the initial values, allowing you to change rotations only.

Normalize output angle — Option to determine whether rotation angles should wrap in full circle

off (default) | on

Select whether the integrated rotation angles should wrap on a full circle (360°). The software ignores this parameter when you set Output Type to Speed.

Dependencies

To enable this parameter, set Output type to Position.

Limit position — Option to limit position of mouse

off (default) | on

Select whether to limit the upper and lower positions of the mouse.

Dependencies

To enable this parameter, set Output type to Position.

Position sensitivity — Mouse sensitivity for translations

0.0001 (default)

Mouse sensitivity for translations. Higher values correspond to higher sensitivity.

Rotation sensitivity — Mouse sensitivity for rotations

0.00001 (default)

Mouse sensitivity for rotations. Higher values correspond to higher sensitivity.

Initial position — Initial condition for translations

[0 0 0] (default)

Initial condition for integrated translations. The software ignores this parameter when you set Output Type to Speed.

Dependencies

To enable this parameter, set Output type to Position or Viewpoint coordinates.

Initial rotation — Initial condition for rotations

[0 0 0] (default)

Initial condition for integrated rotations. The software ignores this parameter when you set Output Type to Speed.

Dependencies

To enable this parameter, set Output type to Position or Viewpoint coordinates.

Lower position limit — Lower limit of mouse

[-100 -100 -100] (default)

Position coordinates for the lower limit of the mouse.

Dependencies

To enable this parameter:

• Set Output type to Position.

• Select Limit position parameter.

Upper position limit — Upper limit of mouse

[100 100 100] (default)

Position coordinates for the upper limit of the mouse.

Dependencies

To enable this parameter:

• Set Output type to Position.

• Select Limit position parameter.

Version History

Introduced in R2007b

R2025a: Renamed from Space Mouse Input

To reflect the Simulink^® library change, the Space Mouse Input block is now called Simulation 3D Space Mouse. The behavior remains the same.
