title: Improvement of rotary encoders in human-machine-interfaces through optimized acoustic feedback.
abstract: This work investigates the effect of the acoustic feedback of rotary encoders that are common in current human-machine-interfaces. The results are based on subjective trials in which the probands had to complete generic tasks using an encoder with programmable electro acoustic feedback. The tasks had to be performed with individually optimized feedback and two reference conditions. The results of the investigation showed the advantage of well-defined acoustic feedback on both accuracy and speed of task fulfillment.
