Towards developing an interface for human-robot interaction, this paper proposes a two-level approach to recognise gestures which are composed of trajectories followed by different body parts. In a first level, individual trajectories are described by a set of key-points. These points are chosen as the corners of the curvature function associated to the trajectory, which will be estimated using and adaptive, non-iterative scheme. This adaptive representation allows removing noise while preserving detail in curvature at different scales. In a second level, gestures are characterised through global properties of the trajectories that compose them. Gesture recognition is performed using a confidence value that integrates both levels. Experimental results show that the performance of the proposed method is high in terms of computational cost and memory consumption, and gesture recognition ability. (C) 2009 Elsevier B.V.

QoS metrics-in-the-loop for endowing runtime self-adaptation to robotic software architectures

A. Romero-Garces, R. Salles De Freitas, R. Marfil, C. Vicente-Chicote, J. Martinez, J. F. Ingles-Romero, A. Bandera

Summary: This paper proposes an approach to self-adaptation in robots by modeling behavior variability at design-time and allowing the robot to configure its behavior at runtime based on contextual information. This approach is supported by a model-based framework that allows robotic engineers to specify behavior variation points, contextual information, and non-functional properties for measuring Quality-of-Service (QoS) of the robot. The framework automatically generates the runtime infrastructure for the robot to adapt its behavior and achieve the best QoS according to its current context.

Still room for improvement in traditional 3D interaction: selecting the fixed axis in the virtual trackball

Daniel Gonzalez-Toledo, Maria Cuevas-Rodriguez, Luis Molina-Tanco, Arcadio Reyes-Lecuona

Summary: Virtual trackball techniques are widely used for 3D interaction through interfaces with limited degrees of freedom. This study conducted an experiment using a mouse and touch device to investigate the effects of selecting different fixed axes based on the user's mental model. The findings suggest that consistency between the fixed axis and the object's intrinsic axis positively impacts usability. The study highlights the importance of considering implementations that allow for selecting different fixed axes for specific objects in future reduced-DoF interaction interfaces.

Extending the Evaluation of Social Assistive Robots With Accessibility Indicators: The AUSUS Evaluation Framework

Ana Iglesias, Javier Garcia, Angel Garcia-Olaya, Raquel Fuentetaja, Fernando Fernandez, Adrian Romero-Garces, Rebeca Marfil, Antonio Bandera, Karine Lan Hing Ting, Dimitri Voilmy, Alvaro Duenas, Cristina Suarez-Mejias

Summary: The introduction of robots in the real world requires evaluation of factors like usability, user experience, social acceptance, and societal impact. This article proposes an extension of a popular HRI evaluation framework to include accessibility as a new evaluation factor. The proposed AUSUS approach considers Accessibility, Usability, Social acceptance, User experience, and Societal impact, and was tested in a use case with a socially assistive robotic platform for comprehensive geriatric assessment.

On Managing Knowledge for MAPE-K Loops in Self-Adaptive Robotics Using a Graph-Based Runtime Model

Adrian Romero-Garces, Alejandro Hidalgo-Paniagua, Martin Gonzalez-Garcia, Antonio Bandera

Summary: Service robotics involves designing robots that work in dynamic and open environments, and the MAPE-K loops are a popular real-time self-adaptation scheme that coordinates multiple loops to solve complex problems. This paper describes the use of a graph-based representation, the Deep State Representation (DSR), as the knowledge component in the MAPE-K scheme applied in robotics, which has been successfully applied in a retail intralogistics scenario.

Vision-based techniques for automatic marine plankton classification

David Sosa-Trejo, Antonio Bandera, Martin Gonzalez, Santiago Hernandez-Leon

Summary: Since the 19th century, scientists have tried to quantify species distributions using techniques such as direct counting and microscopes. Automatic image processing and classification methods are now being utilized to avoid manual procedures for classifying marine plankton. This article summarizes the techniques proposed for classifying marine plankton from the beginning of this field to the present day, focusing on automatic methods that utilize image processing.

Evolution of Socially-Aware Robot Navigation

Silvia Guillen-Ruiz, Juan Pedro Bandera, Alejandro Hidalgo-Paniagua, Antonio Bandera

Summary: In recent years, there has been growing commercial and research interest in service robots operating in everyday environments. These devices are expected to autonomously navigate in crowded environments while taking into account movement efficiency, safety, and social acceptability. Incorporating socially aware criteria into traditional path planning modules to react to human behavior without causing discomfort presents a complex challenge. This review explores approaches to socially aware navigation and categorizes them based on the strategies adopted by robots to manage interaction or cooperation with humans.

Inner Speech: A Mechanism for Self-coordinating Decision Making Processes in Robotics

Adrian Romero-Garces, Alejandro Hidalgo-Paniagua, Pablo Bustos, Rebeca Marfil, Antonio Bandera

Summary: The experience of inner speech is common and plays a relevant role in generating spontaneous responses to the context, as well as regulating thoughts and behaviors. Intimately tied to our sense of self, inner speech provides a continuous monologue of thoughts through internalization, which is essential for structuring and regulating activities. This paper emphasizes the specific aspect of inner speech and demonstrates examples in the CORTEX software architecture, where semantic tokens are used for internalizing the world and regulating decision making activities.

Summary: This paper describes the embedding of an eye detection system on a Zynq XCZU4EV UltraScale+ MPSoC. The system is used in a remote iris recognition application, requiring high resolution images and the ability to detect only focused eye images. By utilizing the neural network's multi-channel input advantage, the system uses grayscale images and high-pass filtered versions as inputs to the CNN. Experimental validation demonstrates the effectiveness of the system.
