Conference paper (peer-reviewed)abstract
- A major challenge for the European electronic industry is to enhance productivity while reducing costs and ensuring quality in development, integration and maintenance. Model-Driven Engineering (MDE) principles and techniques have already shown promising capabilities but still need to scale to support real-world scenarios implied by the full deployment and use of complex electronic components and systems. Moreover, maintaining efficient traceability, integration and communication between two fundamental system life-time phases (design time and runtime) is another challenge facing scalability of MDE. This paper presents an overview of the ECSEL project entitled "MegaModelling at runtime -- Scalable model-based framework for continuous development and runtime validation of complex systems" (MegaM@Rt2), whose aim is to address the above mentioned challenges facing MDE. Driven by both large and small industrial enterprises, with the support of research partners and technology providers, MegaM@Rt2 aims to deliver a framework of tools and methods for: 1) system engineering/design & continuous development, 2) related runtime analysis and 3) global model & traceability management, respectively. The diverse industrial use cases (covering domains such as aeronautics, railway, construction and telecommunications) will integrate and apply such a framework that shall demonstrate the validation of the MegaM@Rt2 solution.

Journal article (peer-reviewed)abstract
- The informational age is marked by the Internet and the media as key factors, with complex mutual interactions. However, they are recognized to increasingly produce negative consequences, such as Problematic Internet Use (PIU) and its inadequate media portrayal. This study represents a comprehensive approach on the media portrayal of PIU via content analysis of national daily newspapers in eight countries from the Eurasian continent. The cross-sectional research included predefined intervals in 2014 and 2018. The search retrieved 212 articles with balanced distribution for designated periods, and predominant publishing in the largest countries. The results revealed that the articles with neutral narratives and national scopes are the most frequent, while the coverage on youth risks (like cyberbullying and excessive social media use) is predominant. This study is a pioneer attempt to give multinational and multi-layered portrayal on the stories that grab the media attention, dictate public interest and guide health policies.

Design of the Human-Robot Interaction for a Semi-Autonomous Service Robot to Assist Elderly People
- 2015
-
In: AMBIENT ASSISTED LIVING, AAL 2014. - Cham : Springer Berlin/Heidelberg. - 9783319118659 - 9783319118666 ; , s. 15-29

Conference paper (peer-reviewed)abstract
- Service robots could support elderly people’s activities of daily living and enable them to live in their own residences independently as long as possible. Current robot technology does not allow reliable fully autonomous operation of service robots with manipulation capabilities in the heterogeneous environments of private homes. We developed and evaluated a usage concept for semi-autonomous robot control as well as user interfaces for three user groups. Elderly people are provided with simple access to autonomous robot services through a handheld device. In case of problems with autonomous execution the robot contacts informal caregivers (e.g. relatives) who can support the robot using semi-autonomous teleoperation. To solve more complex problems, professional teleoperators are contacted who have extended remote access.

Semi-Autonomous Domestic Service Robots : Evaluation of a User Interface for Remote Manipulation and Navigation With Focus on Effects of Stereoscopic Display
- 2015
-
In: International Journal of Social Robotics. - : Springer Netherlands. - 1875-4791 .- 1875-4805. ; 7:2, s. 183-202
-
Journal article (peer-reviewed)abstract
- In this article, we evaluate a novel type of user interface for remotely resolving challenging situations for service robots in domestic environments. Our focus is on potential advantages of stereoscopic display. The user interface is based on a control architecture that allows involvement of a remote human operator when the robot encounters a problem. It offers semi-autonomous remote manipulation and navigation with low-cost interaction devices, incorporates global 3D environment mapping, and follows an ecological visualization approach that integrates 2D laser data, 3D depth camera data, RGB data, a robot model, constantly updated global 2D and 3D environment maps, and indicators into a single 3D scene with user-adjustable viewpoints and optional viewpoint-based control. We carried out an experiment with 28 participants in a home-like environment investigating the utility of stereoscopic display for three types of task: defining the shape of an unknown or unrecognized object to be grasped, positioning the gripper for semi-autonomous reaching and grasping, and navigating the robot around obstacles. Participants were able to successfully complete all tasks and highly approved the user interface in both monoscopic and stereoscopic display modes. They were significantly faster under stereoscopic display in positioning the gripper. For the other two task types, there was a tendency for faster task completion in stereo mode that would need to be verified in further studies. We did not find significant differences in perceived workload between display types for any type of task. We conclude that stereoscopic display seems to be a useful optional display mode for this type of user interface but that its utility may vary depending on the task.

Teleoperation of Domestic Service Robots : Effects of Global 3D Environment Maps in the User Interface on Operators’ Cognitive and Performance Metrics
- 2013

In: Proceedings of the 5th International Conference, ICSR 2013, Bristol, UK, October 27-29, 2013. - Cham : Springer. - 9783319026749 - 9783319026756 ; , s. 392-401
-
Book chapter (peer-reviewed)abstract
- This paper investigates the suitability of visualizing global 3D environment maps generated from RGB-D sensor data in teleoperation user interfaces for service robots. We carried out a controlled experiment involving 27 participants, four teleoperation tasks, and two types of novel global 3D mapping techniques. Results show substantial advantages of global 3D mapping over a control condition for three of the four tasks. Global 3D mapping in the user interface lead to reduced search times for objects and to fewer collisions. In most situations it also resulted in less operator workload, higher situation awareness, and higher accuracy of operators’ mental models of the remote environment.

Teleoperating Assistive Robots : A Novel User Interface for Remote Manipulation and Navigation Relying on Semi-Autonomy and Global 3D Environment Mapping
- 2014
-
Other publication (other academic/artistic)abstract
- Despite remarkable progress of service robotics in recent years, it seems that a fully autonomous robot which would be able to solve everyday household tasks in a safe and reliable manner is still unachievable. To overcome thisproblem, we present solution for a semi-autonomous robot where a remote human operator may take over the robot control from an autonomous system to quickly asses the situation and carry out subtasks which cannot be finishedautomatically. A key component of our solution is the user interface based on a mixed reality 3D environment and fused sensor data which provides a high level of situational and spatial awareness for teleoperation as well as for telemanipulation. The robot control is based on low-cost commodity hardware, optionally including a 3D mouse and stereoscopic display. The interface requires only a brief training and allows short task completion times even when operated by novice users. Its usefulness was verified in two controlled experiments.

Towards Robust Personal Assistant Robots: Experience Gained in the SRS Project
- 2012
-
In: IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2012. - : IEEE. - 9781467317375 ; , s. 1651-1657
-
Conference paper (peer-reviewed)abstract
- SRS is a European research project for building robust personal assistant robots using ROS (Robotic Operating System) and Care-O-bot (COB) 3 as the initial demonstration platform. In this paper, experience gained while building the SRS system is presented. A main contribution of the paper is the SRS autonomous control framework. The framework is divided into two parts. First, it has an automatic task planner, which initialises actions on the symbolic level. The planner produces proactive robotic behaviours based on updated semantic knowledge. Second, it has an action executive for coordination actions at the level of sensing and actuation. The executive produces reactive behaviours in well-defined domains. The two parts are integrated by fuzzy logic based symbolic grounding. As a whole, they represent the framework for autonomous control. Based on the framework, several new components and user interfaces are integrated on top of COB's existing capabilities to enable robust fetch and carry in unstructured environments. The implementation strategy and results are discussed at the end of the paper.
