In this paper, we present a framework for the integration of force feedback information in a NASA NextGen Volumetric Cockpit Situation Display (CSD). With the current CSD, the user retrieves operational information solely through visual displays and interacts with the CSD tools through using a mouse. The advanced capabilities of the CSD may require complex manipulation of information which may be difficult to perform with input devices found in today's cockpits. Performance with the CSD could benefit from a new user input device and enhanced user feedback modalities that can be operated safely, effectively, and intuitively in a cockpit environment. In this work, we investigate the addition of force feedback in two key CSD tasks: object selection and route manipulation. Different force feedback models were applied to communicate guidance commands, such as collision avoidance and target contact. We also discuss the development of a GUI-based software interface to allow the integration of a haptic device for the CSD. A preliminary user study was conducted on a testbed system using the Novint Falcon force-feedback device. A full experiment, assessing the effectiveness and usability of the feedback model in the CSD, will be performed in the next phase of our research.
