A Cognitive Architecture for Robotic Hand Posture Learning
2005
This paper deals with the design and implementation of a visual control of a robotic system composed of a dexterous hand and video camera. The aim of the proposed system is to reproduce the movements of a human hand in order to learn complex manipulation tasks or to interact with the user. A novel algorithm for robust and fast fingertips localization and tracking is presented. A suitable kinematic hand model is adopted to achieve a fast and acceptable solution to an inverse kinematics problem. The system is part of a cognitive architecture for posture learning that integrates the perceptions by a high-level representation of the scene and of the observed actions. The anthropomorphic robotic…
Moving RTS/CTS to the frequency domain: an efficient contention scheme for 802.11ax networks
2019
In this paper, we propose a contention mechanism based on the execution of multiple contention rounds in the frequency domain (ReCHo), which is designed to offer high throughput performance and robustness with respect to imperfect carrier sensing. The main idea is using narrow tones as signalling messages for performing channel access contentions and allowing the Access Point (AP) to echo these signals, in order to extend the sensing capabilities to all the stations associated to the AP. In particular, we refer to the emerging IEEE 802.11ax standard, showing how our scheme can boost performance of random access with respect to the current version of IEEE 802.11ax OFDMA Back-Off (OBO), even …
Effects of menu structure and touch screen scrolling style on the variability of glance durations during in-vehicle visual search tasks.
2011
The effects of alternative navigation device display features on drivers' visual sampling efficiency while searching forpoints of interest were studied in two driving simulation experiments with 40 participants. Given that the number of display items was sufficient, display features that facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations. As predicted, compared with a grid-style menu, searching information in a list-style menu while driving led to smaller variance in durations of in-vehicle glances, in particular with nine item displays. Kinetic touch screen scrolling induced a greater number of very short in-v…
Dual Information Systems : A Review Of Factors Affecting Their Use
2019
More and more information systems (IS) are designed to address a blend of hedonic and utilitarian purposes, and hence become what information system scholars call today “dual systems.” The aim of this research is chiefly to provide a holistic perspective for research done regarding dual IS (i.e., what factors affect users’ adoption and post-adoption of these systems) in order to assess the state of knowledge in this area and to provide a reference point for system designers. To achieve this goal, we started out with a systematic literature review (35 articles), and analyzed the articles in terms of their theoretical background, constructs and findings. The results suggest that there is an i…
Common Misunderstandings of Deterrence Theory in Information Systems Research and Future Research Directions
2022
In the 1980s, information systems (IS) borrowed deterrence theory (DT) from the field of criminology to explain information security behaviors (or intention). Today, DT is among the most commonly used theories in IS security research. Our review of IS research applying DT highlights that many fundamental assumptions of DT are unrecognized and therefore unexamined. This may have resulted in misunderstandings and conceptual confusions regarding some of the basic concepts of DT. For example, some IS studies confuse general deterrence with specific deterrence or do not recognize the difference between the two. Moreover, these fundamental assumptions, when directly examined, may provide importan…
A Knowledge Interface System for Information and Cyber Security Using Semantic Wiki
2018
Resilience against information and cyber security threats has become an essential ability for organizations to maintain business continuity. As bulletproof security is an unattainable goal, organizations need to concentrate to select optimal countermeasures against information and cyber security threats. Implementation of cyber risk management actions require special knowledge and resources, which especially small and medium-size enterprises often lack. Information and cyber security risk management establish knowledge intensive business processes, which can be assisted with a proper knowledge management system. This paper analyzes how Semantic MediaWiki could be used as a platform to assis…
Information Systems Architecture and Technology: Proceedings of 38th International Conference on Information Systems Architecture and Technology – IS…
2018
This three-volume set of books presents advances in the development of concepts and techniques in the area of new technologies and contemporary information system architectures. It guides readers through solving specific research and analytical problems to obtain useful knowledge and business value from the data. Each chapter provides an analysis of a specific technical problem, followed by the numerical analysis, simulation and implementation of the solution to the problem. The books constitute the refereed proceedings of the 2017 38th International Conference “Information Systems Architecture and Technology,” or ISAT 2017, held on September 17–19, 2017 in Szklarska Poręba, Poland. The con…
Towards an Internationalization of the Information Systems Curriculum
2012
Globalization has changed the requirements to professionals and students in all branches and sectors significantly in the past decade. However in the domain of Information Systems, these changes have not yet found their way into current study programs and curricula. We identify and validate core internationalization competences and their relation to IS specific competences based on an initial set of competence categories. This is the basis for designing learning services of the future. The presented study aims at validating both and identifying additional categories and competences. In this paper, we present the first results of this study focusing on the internationalization and knowledge …
