Robots and Wizards: An Investigation Into Natural Human–Robot Interaction

Abstract

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

Robot System Assistant (RoSA): Towards Intuitive Multi-Modal and Multi-Device Human-Robot Interaction

“…In our earlier Wizard of Oz (WoZ) study [6], we reviewed different interaction modalities required for an intuitive HRI. The participants were permitted to use different features like gestures, speech, mimics, and gaze without any limitations to communicate with a cobot and execute different tasks like cube stacking.…”

“…With the aim of a better understanding of human behavior in robotic interaction scenarios, we carried out an extensive Wizard of Oz (WoZ) study [6] to examine common communication intuitions of untaught human interaction partners. In addition, we worked out human key actions to approach human-robot interactions.…”

Intuitiveness Level: Frustration-Based Methodology for Human–Robot Interaction Gesture Elicitation

“…Since this paper is focused on finding a set of intuitive gestures, the subconscious approach is adopted, and it is applied through the use of experiments that make the volunteer perform gestures in the most spontaneous way possible, a concept from psycholinguistics (see Section II-A. To do this, a common methodology is that of the Wizard of OZ (WoZ) [38], [39], where the volunteer interacts with a machine while thinking that it is acting in an autonomous manner, when in fact the machine is, without the volunteers' knowledge, being controlled remotely by another person. In this way, as the volunteers think that they are actually interacting with the machine, the interaction becomes more spontaneous and the volunteers tend to perform gestures that, subconsciously, are the most intuitive.…”

Human-Robot Interaction Review: Challenges and Solutions for Modern Industrial Environments

“…However, achieving natural interaction is not a simple task because it requires continuous monitoring of the surroundings and surveilling the communication flow direction to assure safety while interacting in the communication [58]. Researchers defend several approaches such as voice commanding, gesture recognition [59], collision avoidance and human-aware navigation, among other solutions to achieve natural interaction [1], [29], [60]- [62].…”
