Target size guidelines for interactive displays on the flight dec

It was confirmed statistically that all flight modes are different in character. The potential impact of vibration, touch target size and placement was evaluated. All factors were found to have a significant impact. As shown in previous work the target size is the most significant factor, which may be utilised to minimise other degrading factors by selecting an appropriate target size. It was demonstrated that using touch-enabled devices that are fixed in place in vibrating environments produces significantly higher error rates than when the device can be held by the user.
