Studies on Throttle sticks in high speed crafts - haptics in mechanical, electronic and haptic feedback interfaces

The haptic properties of the throttle sticks in the Hauk-class Fast Patrol Boat of the Norwegian Navy have been changed due to digitalization and automation of the engine control. This is an example of how haptic qualities in general are lost in the transition from mechanical to electronic interface controls. Haptic feedback is a potential way of returning the sense of touch to the interface. In order to design meaningful haptic feedback we need to understand the role haptics take when people interact with technology. This article discusses the possibilities of haptic feedback in applications such as high speed crafts through studying the effect of a change in throttle sticks on the naval ships.
