Any possible movement of a rigid body, no matter how complex, can be expressed as a combination of three translations and three rotations, the basic six degrees of freedom (6DoF) [LM10]. Volume visualisation as exploited in tomography packages, (e.g. Avizo (FEI), ImageJ, Paraview TomVis or Drishti) allow for multiple other parameters and other rigid bodies to be changed. Current users of these systems often have to exploit a single mouse and contrived keystrokes for even the simplest of data exploration and animation task.
Using a hand, a user can send and receive information through force/torque and displacement/rotation; which are translated by drivers for interpretation by the application. HCI studies classified input devices into two groups: isotonic (senses displacement or free movement with zero or constant resistance; e.g. the mouse) and isometric devices (senses force without perceptibly movement; e.g. a joystick) [Zha95]. Recently a new 6DoF device (Wing [Wor14]), allows one hand to combine both of these.
A new python driver, with improved calibration, has been written to link with the Drishti package [Lim12]; which has been evaluated with XCT users. Results showed user preference and comfort criteria (included expected cost), as well as timed specific tasks for comparative XCT viewing - creating a system that has potential ease of use and speed up in exploration and discovery.
Future work is planned to include multiple Wing devices allowing then for simultaneous interaction; for example manipulating both light parameters and object position; or changing clipping plane and object transparency.
