Intersectional HCI recognizes that humans' interconnected social identities shape their experiences with technology. However, intersectional HCI requires extensive resources, such as access to intersectional populations, which many HCI practitioners may lack. For these practitioners, we present an analytical approach to bring intersectional lenses to HCI practices. The approach uses types—not at the level of identities, but at the level of personal traits drawn from foundational research. We first formally prove that certain analytical methods for detecting inclusivity issues can be meaningfully composed to provide equitable consideration of typically overlooked populations; then present four design use-cases to illustrate what the approach brings to HCI practices; and then empirically investigated one of the four use-cases with 24 HCI participants. Results show that practitioners using the compositional approach detected even more intersectional inclusivity problems than those using a complementary intersectional approach.

Imbuing furniture with robot properties reduces the physical labor and time needed for arranging spaces, such as homes, classrooms, and offices. Outsourcing labor tasks to robot furniture requires users’ involvement with functional user interfaces. We performed a user study on multi-robot furniture and added additional features based on the study results. The study involved 12 participants rearranging multiple non-robotic and robotic chairs (ChairBots). Results from the video and interview analysis revealed five high-level features missing in the original ChairBot: dual screen-based user interface, the ability to save and to set arrangements, the ability to move in multi-robot formations, the ability to snap to angles/gridlines, and higher movement precision. The improved system allows users to control multiple furniture robots, both locally and remotely. Such improvement sets the baseline functionalities of robot furniture arrangement systems while extending the potential utilization of established robotic chairs.

Robots sometimes face hardware and algorithmic challenges that exceed their capabilities, e.g., an armless robot pressing an elevator button. Previous work suggests that rather than augmenting the robot capabilities, sometimes robots can simply ask for help. A central contribution of this paper is the discovery of how people's helping behaviors vary within local microcultures, i.e., shared patterns of behaviors and norms linked to local atmospheric conditions and situations. Our methods combine techniques from both social robotics research and ethnography to investigate how people's helping behaviors toward robots vary across six cafes on a single college campus. We deploy a simple robot to request help ordering items, analyzing the 268 interaction instances to find significant variations in both help and care behaviors toward the robot. Microcultural and situational factors influence this help, motivating the inclusion of cultural criteria into the behavioral predictions of human-robot interaction systems.

Over the summer of 2018, CHARISMA Robotics Laboratory at Oregon State University invited a Theater Artist to collaborate on two interdisciplinary robot theater productions using ChairBots and human performers. Both productions shared in a three-week development period, the same development team and performing robots, and culminated in live performances. This paper acts as a companion to the video documentation of these productions, addressing the novelty and contributions, both technical and creative, of dancing with robot furniture.

This paper consists of a failure analysis of two robot performance productions. Both productions included three-week rehearsal periods, and culminated in live performances including both robots and humans. To develop these productions, a theater artist collaborated with a robotics lab to develop, (1) a narrative dance performed live on stage and (2) an improvisational performance in a public space. While the interdisciplinary team did not set out to explore robot failures, failures played an ever-present role during the eighteen rehearsals and two live performances. This paper details strategies for addressing, planning for, and rehearsing responses to robot failures on stage, both technical and choreographic. In addition to scaffolding future robot theater performances, we discuss how these strategies apply to other customer- and audience-facing robots, including sponsor demos. The on-stage exploration of robot chairs and human performers also suggests that humans can conceptualize minimal robots as both characters and props, moving fluidly from one to the other. We hope these strategies ensure that future audiences will want the robot shows to go on, as well as expand ideas about the types of robots that can be cast in future human-robot productions.
