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 GUIbased 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.

Future cockpits will likely include new onboard technologies, such as cockpit displays of traffic information, to help support future flight deck roles and responsibilities. These new technologies may benefit from multimodal feedback to aid pilot information processing. The current study investigated the effects of multiple levels of force feedback on operator performance in an aviation task. Participants were presented with two different types of force feedback (gravitational and spring force feedback) for a discrete targeting task, with multiple levels of gain examined for each force feedback type. Approach time and time in target were recorded. Results suggested that the two highest levels of gravitational force significantly reduced approach times relative to the lowest level of gravitational force. Spring force level only affected time in target.
