The driver class for the Locograph will be a Python class called "Locograph". Locograph will handle connecting to the USB device using libusb, meaning a user of this class merely needs to instantiate one and start asking it for values.
Here is something like a UML diagram for Locograph:
Locograph A Locograph has the following attributes: [*] position: A tuple of length three - (x, y, z) - expressing coordinate change relative to the laptop in the global Cartesian space. [*] bearing: A number - 0 to 1 - expressing how much of a rotation the laptop has completed in the global Cartesian space.
A Locograph offers the following methods: [*] getPosition(): returns self.position [*] getBearing(): returns self.bearing [*] _updateFromDevice(): polls the USB device for new values. [*] _mapDevice(): sets up the USB device originally. [*] reset(): client asks for coordinate reset. [*] _reset(): ask USB device for coordinate reset.
