Robots and wizards : an investigation into natural Human–Robot Interaction

Abstract

The goal of the study was to research different communication modalities needed for intuitiveHuman-Robot Interaction. This study utilizes a Wizard of Oz prototyping method to enable a restriction-free,intuitive interaction with an industrial robot. The data from 36 test subjects suggests a high preference forspeech input, automatic path planning and pointing gestures. The catalogue developed during this experimentcontains intrinsic gestures suggesting that the two most popular gestures per action can be sufficient tocover the majority of users. The system scored an average of 74% in different user interface experiencequestionnaires, while containing forced flaws. These findings allow a future development of an intuitiveHuman-Robot interaction system with high user acceptance.
