The Need for Verbal Robot Explanations and How People Would Like a Robot To Explain Itself

Robot explanation, robot failure

Although non-verbal cues such as arm movement and eye gaze can convey robot intention, they alone may not provide enough information for a human to fully understand a robot’s behavior. To better understand how to convey robot intention, we conducted an experiment (N = 366) investigating the need for robots to explain, and the… Continue reading The Need for Verbal Robot Explanations and How People Would Like a Robot To Explain Itself

Reasons People Want Explanations After Unrecoverable Pre-Handover Failures

Codes for explanation reasoning. Shown are those that appeared more than 12 times.

Most research on human-robot handovers focuses on the development of comfortable and efficient HRI; few have studied handover failures. If a failure occurs in the beginning of the interaction, it prevents the whole handover process and destroys trust. Here we analyze the underlying reasons why people want explanations in a handover scenario where a… Continue reading Reasons People Want Explanations After Unrecoverable Pre-Handover Failures

The Effects of Proactive Release Behaviors During Human-Robot Handovers

4 Baxter robot released the object and the participant took it

Most research on human-robot handovers focuses on how the robot should approach human receivers and notify them of the readiness to take an object; few studies have investigated the effects of different release behaviors. Not releasing an object when a person desires to take it breaks handover fluency and creates a bad handover experience.… Continue reading The Effects of Proactive Release Behaviors During Human-Robot Handovers

Investigating Human-Robot Handover Release Behaviors

Human-Robot Handover

Introduction Most human-robot handovers focus on how to approach human receivers and notify the readiness, few have investigated the effects of difference release behaviors of objects. The whole handover process consists of three phases: the approach phase, the signal phase, and the transfer phase. Failures during the transfer phase have serious consequences: Early releases lead… Continue reading Investigating Human-Robot Handover Release Behaviors
