Not very many posts in 2019 but this does not mean that we have not conducted some really interesting research in our lab. On the contrary
So, over the next few weeks I will begin posting some of our most recent accomplishments.
Here is just one:

Understanding and Resolving Failures in Human-Robot Interaction
Posted by Tal Oron-Gilad in HRI, Human-Robot Interaction, News, robotics on June 2, 2018
Shanee Honig and I have just finished a literature review on resolving failures in HRI. The Full publication can be found in Frontiers .
We mapped a taxonomy of failures, separating technical failures from interaction failures [see 1].
After reviewing the cognitive considerations that influence people’s ability to detect and solve robot failures, as well as the literature in failure handling in human-robot interactions, we developed an information processing model called the Robot Failure Human Information Processing (RF-HIP) Model, modeled after Wogalter’s C-HIP (an elaboration of Shannon & Weavers 1948 model of communication), to describe the way people perceive, process, and act on failures in human robot interactions.
- RF-HIP can be used as a tool to systematize the assessment process involved in determining why a particular approach to handling failure is successful or unsuccessful in order to facilitate better design.
abstract
While substantial effort has been invested in making robots more reliable, experience demonstrates that robots operating in unstructured environments are often challenged by frequent failures. Despite this, robots have not yet reached a level of design that allows effective management of faulty or unexpected behavior by untrained users. To understand why this may be the case, an in-depth literature review was done to explore when people perceive and resolve robot failures, how robots communicate failure, how failures influence people’s perceptions and feelings towards robots, and how these effects can be mitigated. 52 studies were identified relating to communicating failures and their causes, the influence of failures on human-robot interaction, and mitigating failures. Since little research has been done on these topics within the Human-Robot Interaction (HRI) community, insights from the fields of human computer interaction (HCI), human factors engineering, cognitive engineering and experimental psychology are presented and discussed. Based on the literature, we developed a model of information processing for robotic failures (Robot Failure Human Information Processing (RF-HIP)), that guides the discussion of our findings. The model describes the way people perceive, process, and act on failures in human robot interaction. The model includes three main parts: (1) communicating failures, (2) perception and comprehension of failures, and (3) solving failures. Each part contains several stages, all influenced by contextual considerations and mitigation strategies. Several gaps in the literature have become evident as a result of this evaluation. More focus has been given to technical failures than interaction failures. Few studies focused on human errors, on communicating failures, or the cognitive, psychological, and social determinants that impact the design of mitigation strategies. By providing the stages of human information processing, RF-HIP can be used as a tool to promote the development of user-centered failure-handling strategies for human-robot interactions.
Towards Socially Aware Person-Following Robots

Here is a new publication from our lab. This is a literature review that is focused on person-following in robotics from the perspective of the user. Published in IEEE THMS.
Abstract:

Come meet us at Ro-Man 2017, where Dr, Vardit Sarne-Fleischmann and Shanee Honig will present our work on Gesture vocabulary for a person following robot.
Abstract— Robots that are designed to support people in different tasks at home and in public areas need to be able to recognize user’s intentions and operate accordingly. To date, research has been mostly concentrated on developing the technological capabilities of the robot and the mechanism of recognition. Still, little is known about navigational commands that could be intuitively communicated by people in order control a robot’s movement. A two-part exploratory study was conducted in order to evaluate how people naturally guide the motion of a robot and whether an existing gesture vocabulary used for human-human communication can be applied to human-robot interaction. Fourteen participants were first asked to demonstrate ten different navigational commands while interacting with a Pioneer robot using a WoZ technique. In the second part of the study participants were asked to identify eight predefined commands from the U.S. Army vocabulary. Results show that simple commands yielded higher consistency among participants regarding the commands they demonstrated. Also, voice commands were more frequent than using gestures, though a combination of both was sometimes more dominant for certain commands. In the second part, an inconsistency of identification rates for opposite commands was observed. The results of this study could serve as a baseline for future developed commands vocabulary promoting a more natural and intuitive human-robot interaction style.
