An assisted navigation method for telepresence robots
Telepresence robots have emerged as a new means of interaction in remote
environments. However, the use of such robots is still limited due to safety
and usability issues when operating in human-like environments. This work addresses
these issues by enhancing the robot navigation through a collaborative
control method that assists the user to negotiate obstacles. The method has been
implemented in a commercial telepresence robot and a user study has been conducted
in order to test the suitability of our approach.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tech
A Low-Cost Tele-Presence Wheelchair System
This paper presents the architecture and implementation of a tele-presence
wheelchair system based on tele-presence robot, intelligent wheelchair, and
touch screen technologies. The tele-presence wheelchair system consists of a
commercial electric wheelchair, an add-on tele-presence interaction module, and
a touchable live video image based user interface (called TIUI). The
tele-presence interaction module is used to provide video-chatting for an
elderly or disabled person with the family members or caregivers, and also
captures the live video of an environment for tele-operation and
semi-autonomous navigation. The user interface developed in our lab allows an
operator to access the system anywhere and directly touch the live video image
of the wheelchair to push it as if he/she did it in the presence. This paper
also discusses the evaluation of the user experience
Brain-Computer Interface meets ROS: A robotic approach to mentally drive telepresence robots
This paper shows and evaluates a novel approach to integrate a non-invasive
Brain-Computer Interface (BCI) with the Robot Operating System (ROS) to
mentally drive a telepresence robot. Controlling a mobile device by using human
brain signals might improve the quality of life of people suffering from severe
physical disabilities or elderly people who cannot move anymore. Thus, the BCI
user is able to actively interact with relatives and friends located in
different rooms thanks to a video streaming connection to the robot. To
facilitate the control of the robot via BCI, we explore new ROS-based
algorithms for navigation and obstacle avoidance, making the system safer and
more reliable. In this regard, the robot can exploit two maps of the
environment, one for localization and one for navigation, and both can be used
also by the BCI user to watch the position of the robot while it is moving. As
demonstrated by the experimental results, the user's cognitive workload is
reduced, decreasing the number of commands necessary to complete the task and
helping him/her to keep attention for longer periods of time.Comment: Accepted in the Proceedings of the 2018 IEEE International Conference

Healthcare Robotics
Robots have the potential to be a game changer in healthcare: improving
health and well-being, filling care gaps, supporting care givers, and aiding
health care workers. However, before robots are able to be widely deployed, it
is crucial that both the research and industrial communities work together to
establish a strong evidence-base for healthcare robotics, and surmount likely
adoption barriers. This article presents a broad contextualization of robots in
healthcare by identifying key stakeholders, care settings, and tasks; reviewing
recent advances in healthcare robotics; and outlining major challenges and
opportunities to their adoption.Comment: 8 pages, Communications of the ACM, 201
Gaze and Gestures in Telepresence: multimodality, embodiment, and roles of collaboration
This paper proposes a controlled experiment to further investigate the
usefulness of gaze awareness and gesture recognition in the support of
collaborative work at a distance. We propose to redesign experiments conducted
several years ago with more recent technology that would: a) enable to better
study of the integration of communication modalities, b) allow users to freely
move while collaborating at a distance and c) avoid asymmetries of
communication between collaborators.Comment: Position paper, International Workshop New Frontiers in Telepresence

Physical Telepresence: Shape Capture and Display for Embodied, Computer-mediated Remote Collaboration
We propose a new approach to Physical Telepresence, based on shared workspaces with the ability to capture and remotely render the shapes of people and objects. In this paper, we describe the concept of shape transmission, and propose interaction techniques to manipulate remote physical objects and physical renderings of shared digital content. We investigate how the representation of user's body parts can be altered to amplify their capabilities for teleoperation. We also describe the details of building and testing prototype Physical Telepresence workspaces based on shape displays. A preliminary evaluation shows how users are able to manipulate remote objects, and we report on our observations of several different manipulation techniques that highlight the expressive nature of our system.National Science Foundation (U.S.).
