Following Angle of a Human-Following Robot

Human-following capabilities of robots may become important in assistive robotic applications to facilitate many daily tasks (e.g. carrying personal items or groceries). Robot’s following distance, following angle and acceleration influence the quality of the interaction between the human and the robot by impacting walking efficiency (e.g., pace, flow and unwanted stops), user comfort and robot likability.

ICR Our team gave a presentation at the ICR 2016 conference focusing on Subjective preferences regarding human-following robots: preliminary evidence from laboratory experiments.

The Influence of Following Angle on Performance Metrics -

Following Angles of a human-following Pioneer LX Robot (Honig, Katz, Edan & Oron-Gilad)

  • This research effort is led by our graduate student Shanee Honig
  • For the person-tracking and following algorithm (Dror Katz & Yael Edan, work in progress) we use the Pioneer LX Robot’s built in camera and a Microsoft Kinect.
  • Currently we focus on 3 angles of following: back following (0 degree angle), a 30 degree angle, and a 60 degree angle.
  • We use a personal item manipulation (e.g., wallet) to examine how participants engage with the robot. Naturally when participants place a personal item on the robot, they become more engaged with it.
  • Come see us at the HCII 2016 where we will present a poster on sensitivity of older users (68 and above) to the quality of interaction, depending on robot’s following distance and acceleration, and the context of walk – Follow Me: Proxemics and Responsiveness Preferences of Older Users in a Human-Following Robot.

Human-Robot Interaction (HRI) in future military operations – The book

For those of you who are interested in the role of Human-Robot Interaction (HRI) in future military operations, Mike Barnes and Florian Jencth have recently edited a handbook titled “Human-Robot Interactions in Future Military Operations“. The book is a collection of chapters written by well recognized researchers in the area. It provides a wide range of topics from operators interacting with small ground robots and aerial vehicles to supervising large, near-autonomous vehicles capable of intelligent battlefield behaviors.

I was honored to contribute a chapter to this book. Together with my colleague and former student Yaniv Minkov we discuss the issue of “Remotely Operated Vehicles (ROVs) from the bottom-up operational perspective“.

Robotic Displays For Dismounted Warfighters: A Field Study

Here is the abstract of one of my latest studies. It appears in a special issue of JCEDM “Improving Human-Robot Interaction in Complex Operational Environments: Translating Theory into Practice”

* Oron-Gilad, T., Redden, E.S. and Minkov, Y. (2011). Robotic Displays for Dismounted Warfighter Situation Awareness of Remote Locations: A field study, Journal of Cognitive Ergonomics and Decision Making. Accepted November 2010.Volume 5, Number 1, March 2011, pp. 29–54.
This study investigated scalability of unmanned vehicle displays for dismounted warfighters. Task performance, workload and preferences for three display devices were examined in two operational settings: tele-operation of an unmanned ground vehicle and intelligence gathering from a remote unmanned vehicle. Previous research has demonstrated variability in operational needs with regard to active tele-operation versus passive intelligence gathering. Thus, it was important to identify whether there was actually a dichotomy between the two in terms of screen space requirements and whether this difference stems from task differences or other factors.  Thirty-one soldiers participated in a field study at Ft. Benning, GA. They were required to perform tele-operation and intelligence gathering tasks. Results reconfirmed our hypothesis that display type influences performance in intelligence-related tasks that require the use of video feed and digital map. No significant differences among display types were found in the UGV tele-operation task. In conclusion, dismounted warfighters can adequately perform both active and passive duties with a hand held device where the video window is as small as 4.3 inches in diameter. However, monocular HMDs for robotic displays can be problematic and should be carefully assessed before use in dismounted warfighters missions.
