This paper investigates how a teleoperated surgical robot recongures teamwork in the operating room by spatially redistributing team members. We report on ndings from two years of eldwork at two hospitals, including interviews and video data. We nd that while in non-robotic cases team members huddle together, physically touching, introduction of a surgical robot increases physical and sensory distance between team members. This spatial rearrangement has implications for both cognitive and aective dimensions of collaborative surgical work. Cognitive distance is increased, necessitating new eorts to maintain situation awareness and common ground. Moreover, aective distance is introduced, decreasing sensitivity to shared and non-shared aective states and leading to new practices aimed at restoring aective connection within the team. We describe new forms of physical, cognitive, and aective distance associated with teleoperated robotic surgery, and the eects these have on power distribution, practice, and collaborative experience within the surgical team.

This paper explores how humans adapt to a conventional humanoid robot. Video data of participants playing a charade game with a Nao robot were analyzed from a multimodal conversation analysis perspective. Participants soon adjust aspects of turn-design such as word selection, turn length and prosody, thereby adapting to the robot's limited perceptive abilities as they become apparent in the interaction. However, coordination of turns-at-talk remains troublesome throughout the encounter, as evidenced by overlapping turns and lengthy silences around possible turn endings. The study discusses how the robot design can be improved to support the problematic taking of turns-at-talk with humans. Two programming strategies to address the identified problems are presented: 1. to program the robot so that it will be systematically receptive at the equivalence to transition relevance places in human-human interaction, and 2. to make the robot preferably produce verbal actions that require a response in a conditional way, rather than making a response only possible.

Smooth traffic presupposes fine coordination between different actors, such as pedestrians, cyclists and car drivers. When autonomous vehicles join regular traffic, they need to coordinate with humans on the road. Prior work has often studied and designed for interaction with autonomous vehicles in structured environments such as traffic intersections. This paper describes aspects of coordination also in less structured situations during mundane maneuvers such as overtaking. Taking an ethnomethodological and conversation analytic approach, the paper analyzes video recordings of self-driving shuttle buses in Sweden. Initial findings suggest that the shuttle buses currently do not comply with cyclists' expectations of social coordination in traffic. The paper highlights that communication and coordination with human road users is crucial for smooth flow of traffic and successful deployment of autonomous vehicles also in less structured traffic environments.

This paper explores how humans interpret displays of emotion produced by a social robot in real world situated interaction. Taking a multimodal conversation analytic approach, we analyze video data of families interacting with a Cozmo robot in their homes. Focusing on one happy and one sad robot animation, we study, on a turn-by-turn basis, how participants respond to audible and visible robot behavior designed to display emotion. We show how emotion animations are consequential for interactional progressivity: While displays of happiness typically move the interaction forward, displays of sadness regularly lead to a reconsideration of previous actions by humans. Furthermore, in making sense of the robot animations people may move beyond the designer's reported intentions, actually broadening the opportunities for their subsequent engagement. We discuss how sadness functions as an interactional "rewind button" and how the inherent vagueness of emotion displays can be deployed in design.

Conceptualizing agency is a long-standing theoretical concern. Taking an ethnomethodological and conversation analytic perspective, we explore agency as the oriented to capacity to produce situationally and sequentially relevant action. Drawing on video recordings of families interacting with the Cozmo toy robot, we present a multimodal analysis of a single episode featuring a variety of rapidly interchanging forms of robotic (non-)agency. We demonstrate how agency is ongoingly constituted in situated interaction between humans and a robot. Describing different ways in which the robot’s statuses as either an agent or an object are interactionally embodied into being, we distinguish “autonomous” agency, hybrid agency, ascribed agency, potential agency and non-agency.
