Collaborative control is a teleoperation system model based on human-robot dialogue. With this model, the robot asks questions to the human in order to obtain assistance with cognition and perception. This enables the human to function as a resource for the robot and help to compensate for limitations of autonomy. To understand how collaborative control influences human-robot interaction, we performed a user study based on contextual inquiry (CI). The study revealed that: (1) dialogue helps users understand problems encountered by the robot and (2) human assistance is a limited resource that must be carefully managed.

The ultimate goal of human natural language interaction is to communicate intentions. However, these intentions are often not directly derivable from the semantics of an utterance (e.g., when linguistic modulations are employed to convey polite-ness, respect, and social standing). Robotic architectures withsimple command-based natural language capabilities are thus not equipped to handle more liberal, yet natural uses of linguistic communicative exchanges. In this paper, we propose novel mechanisms for inferring in-tentions from utterances and generating clarification requests that will allow robots to cope with a much wider range of task-based natural language interactions. We demonstrate the potential of these inference algorithms for natural human-robot interactions by running them as part of an integrated cognitive robotic architecture on a mobile robot in a dialogue-based instruction task.
The Curious Robot as a Case-Study for Comparing Dialog Systems

Modeling interaction with robots raises new and different challenges for dialog modeling than traditional dialog modeling with less embodied machines. We present four case studies of implementing a typical humanrobot interaction scenario with different state ...
The Role of Social Dialogue and Errors in Robots
Proceedings of the 5th International Conference on Human Agent Interaction, 2017
Social robots establish rapport with human users. This work explores the extent to which rapport-building can benefit (or harm) conversations with robots, and under what circumstances this occurs. For example, previous work has shown that agents that make conversational errors are less capable of influencing people than agents that do not make errors [1]. Some work has shown this effect with robots, but prior research has not considered additional factors such as the level of rapport between the person and the robot. We predicted that building rapport through a social dialogue (such as an ice-breaker) could mitigate the detrimental effect of a robot's errors on influence. Our study used a Nao robot programmed to persuade users to agree with its rankings on two "survival tasks" (e.g., lunar survival task). We manipulated both errors and social dialogue:the robot either exhibited errors in the second survival task or not, and users either engaged in an ice-breaker with t...
Human-robot interaction through spoken language dialogue
2000
Abstract The development of robots that are able to accept instructions, via a friendly interface, in terms of concepts that are familiar to a human user remains a challenge. It is argued that designing and building such intelligent robots can be seen as the problem of integrating four main dimensions: human-robot communication, sensory motor skills and perception, decision-making capabilities, and learning.
What the Robot Sees & Understands Facilitates Dialogue
The particular applications that interest us include search and rescue robotics, security, elder/disabled care or assistance, or service robotics. In all of these ap- plication areas, visual perception and internal represen- tations play a pivotal role in how humans,and robots communicate. In general, visual perception plays an important role in communicating,information amongst humans.,It is typically imprecise and humans,usu- ally use their cognitive abilities to interpret the in- tent. We explore real-time probabilistic visual percep- tion in three different roles: (1) the tracking of human limbs; (2) stereo vision for robot and human,naviga- tion; and (3) optical flo w,for detecting salient events and structure from motion. Our visual perception ef- forts are expressed in probability distribution functions (i.e., Bayesian). The robot requires to have this uncer- tainty propagated for any subsequent decision-making task. A related application we are also exploring is us- ing real...
