Evaluation of human performance using touch screen displays in cockpit environment

Touch screen technologies are making their way into aircraft flight deck as a means to the pilot to view and interact with flight data. The usability of touch screens is challenging in this environment: The device is fixed on the cockpit, it is located at arm-length from the pilot and is the subject of vibration, making it harder to select the intended interactive control. In this project, we evaluate human performance and error rate when using touch screens in the flight deck and propose design solutions to improve human's efficiency and satisfaction. Test conditions are the location of the display, vibration profile, use of palm rest, gloves and touch screen technology. 20 participants seat on a vibrating chair configured to be representative of a flight deck and complete the multidirectional selection task defined in the standard ISO 9241 to measure human performance. Results found are compared to existing performance data for non-touch screen interactions. Based on the findings of the experiment, assistive technologies are implemented to mitigate the performance impact of vibration on the pilot, for example algorithm for smart selection based on multi-touch inputs or adaptative button size.
