    The autonomous mobile robot SENARIO: A sensor-aided intelligent navigation system for powered wheelchairs

    No full text
    The SENARIO project is developing a sensor-aided intelligent navigation system that provides high-level navigational aid to users of powered wheelchairs. The authors discuss new and improved technologies developed within SENARIO concerning task/path planning, sensing and positioning for indoor mobile robots as well as user interface issues. The autonomous mobile robot SENARIO, supports semi- or fully autonomous navigation. In semi-autonomous mode the system accepts typical motion commands through a voice-activated or standard joystick interface and supports robot motion with obstacle/collision avoidance features. Fully autonomous mode is a superset of semi-autonomous mode with the additional ability to execute autonomously high-level go-to-goal commands. At its current stage, the project has succeeded in fully supporting semi-autonomous navigation, while experiments on the fully autonomous mode are very encouraging

    ASPIDA: An Observatory for Security and Privacy in the Greek e-Business Sector

    Modern e-business policy aims to better frame and steer progress and advancements towards a legal and security aware framework. However, a large percentage of cases neglects the adoption of good security practices, exposing customers to potential risks. In this work, we present a hybrid approach upon self-assessment, self-improvement and self-regulation motivation, offered by the observAtory for Security and PrIvacy DAta (ASPIDA) system. To address privacy and security weaknesses we monitor and analyze a set of security and privacy metrics and indicators. The evaluation of the aforementioned criteria drives an outcome in the form of a digital badge of good practices for the specific website. This digital badge is a recognition and can be used by the e-business owners as an attraction that frames the services and content they offer to the public. © 2021 ACM

    The PAM-AID project aims to build an intelligent, indoor mobility aid for frail and elderly visually impaired people which will provide both physical and navigational support for walking. The objective is to allow users to retain their personal autonomy and also to take independent exercise. The project involves ongoing user involvement and evaluations of the developing product. The project has five distinct phases: (1) user requirements elicitation, (2) rapid prototyping, (3) construction of a demonstrator, (4) user and carer training, and (5) system validation. This paper reports on the first two phases of the project
