pyspacenavigator

3Dconnexion Space Navigator in Python using raw HID (Windows only). Note: you don't need to install or use any of the drivers or 3Dconnexion software to use this package. It interfaces with the controller directly.

Implements a simple interface to the 6 DoF 3Dconnexion Space Navigator device as well as similar devices. The following 3dconnexion devices are supported:

• SpaceNavigator
• SpaceMouse Pro
• SpaceMouse Pro Wireless
• SpaceMouse Wireless
• 3Dconnexion Universal Receiver
• SpaceMouse Compact
• SpacePilot Pro

Requires pywinusb to access HID data -- this is Windows only.

Basic Usage:

import spacenavigator
import time

success = spacenavigator.open()
if success:
  while 1:
    state = spacenavigator.read()
    print(state.x, state.y, state.z)
    time.sleep(0.5)
  

State objects

State objects returned from read() have 7 attributes: [t,x,y,z,roll,pitch,yaw,button].

• t: timestamp in seconds since the script started.
• x,y,z: translations in the range [-1.0, 1.0]
• roll, pitch, yaw: rotations in the range [-1.0, 1.0].
• button: list of button states (0 or 1), in order specified in the device specifier

API

open(callback=None, button_callback=None, device=None)      
    Open a 3D space navigator device. Makes this device the current active device, which enables the module-level read() and close()
    calls. For multiple devices, use the read() and close() calls on the returned object instead, and don't use the module-level calls.

    Parameters:        
        callback: If callback is provided, it is called on each HID update with a copy of the current state namedtuple  
        button_callback: If button_callback is provided, it is called on each button push, with the arguments (state_tuple, button_state) 
        device: name of device to open, as a string like "SpaceNavigator". Must be one of the values in `supported_devices`. 
                If `None`, chooses the first supported device found.            
    Returns:
        Device object if the device was opened successfully
        None if the device could not be opened
    
read()              Return a namedtuple giving the current device state (t,x,y,z,roll,pitch,yaw,button)
close()             Close the connection to the current device, if it is open
set_led(state)      Set the status of the current devices LED to either on (True) or off (False)
list_devices()      Return a list of supported devices found, or an empty list if none found

open() returns a DeviceSpec object. If you have multiple 3Dconnexion devices, you can use the object-oriented API to access them individually. Each object has the following API, which functions exactly as the above API, but on a per-device basis:

dev.open()          Opens the connection (this is always called by the module-level open command, 
                    so you should not need to use it unless you have called close())
dev.read()          Return the state of the device as namedtuple [t,x,y,z,roll,pitch,yaw,button]
dev.close()         Close this device
dev.set_led(state)  Set the state of the LED on the device to on (True) or off (False)

There are also attributes:

dev.connected       True if the device is connected, False otherwise
dev.state           Convenience property which returns the same value as read()

Other devices

This seems to work with other 3D Connexion devices with some tweaking. This very helpful issue comment illustrates steps to get a new device working.
