Making intelligent systems team players: Case studies and design issues. Volume 1: Human-computer interaction design

Initial results are reported from a multi-year, interdisciplinary effort to provide guidance and assistance for designers of intelligent systems and their user interfaces. The objective is to achieve more effective human-computer interaction (HCI) for systems with real time fault management capabilities. Intelligent fault management systems within the NASA were evaluated for insight into the design of systems with complex HCI. Preliminary results include: (1) a description of real time fault management in aerospace domains; (2) recommendations and examples for improving intelligent systems design and user interface design; (3) identification of issues requiring further research; and (4) recommendations for a development methodology integrating HCI design into intelligent system design

Open plan and academe: pre- and post-hoc conversations

There now exists a strong body of evidence that creative workplaces can, in certain circumstances, exert beneficial influences on organisational cultures and outputs. Academia tends to resist such spaces and faculty buildings. The reasons are explored but the reactions of staff are not found to be different from those reported in the literature on general creative spaces. The success or failure of team oriented workspaces is in large part a socially constructed perception influenced by the manner of implementation and management. As elsewhere new workplaces are about new conversations. The cases studied lead to a model of the tensions inherent in workplace redesign.</p

Managerial learning and development in small firms: implications based on observations of managerial

In this study we set out to examine the conditions for managerial learning in small firms and the implications it gives for how to facilitate and support work-based management development in this context. Empirically, we conduct structured observations of the daily work activities performed by small business managers. A framework based on experiential learning theory is developed and used as an analytical tool to assess the extent to which these work activities provide them with opportunities for work-based learning and development. In short, the results show that small business managers experience a fragmented working day with frequent and different forms of interruptions and unexpected problems during the course of their working day. These interruptions and unexpected problems are something that leaves little time for engaging in reflective observation to effectively learn from their daily work practices. We discuss the implications of our results for theory and research on managerial learning in small firms as well as for the design of university-led management development programs aimed at supporting the experiential learning process of small business managers.academic Experiential learning; managerial learning; managerial work; management development; small firms; structured observations

AwareNotifications: Multi-Device Semantic Notification Handling with User-Defined Preferences

With the increase of connected devices and online services, the number of notifications received by each person is growing. Although notifications are useful to inform users about important information such as new messages and events, the continuous interruptions, the notification duplication, and the rigid delivery can be sources of discomfort. To overcome these issues, we present AwareNotifications, an intelligent system based on user-defined preferences to manage multi-device notifications. AwareNotifications is powered by Semantic Web technologies. By directly exploiting user preferences in the semantic reasoning process, the system is able to identify suitable device(s), modality, and moment(s) to deliver the incoming user notifications. We evaluated AwareNotifications in a user study with 15 participants, in which we compared our system with the "traditional" notification delivery system. The study confirms the perceived effectiveness of AwareNotifications, and provides insights to further improve the system

Reasoning about ideal interruptible moments: A soft computing implementation of an interruption classifier in free-form task environments

Current trends in society and technology make the concept of interruption a central human computer interaction problem. In this work, a novel soft computing implementation for an Interruption Classifier was designed, developed and evaluated that draws from a user model and real-time observations of the user\u27s actions as s/he works on computer-based tasks to determine ideal times to interact with the user. This research is timely as the number of interruptions people experience daily has grown considerably over the last decade. Thus, systems are needed to manage interruptions by reasoning about ideal timings of interactions. This research shows: (1) the classifier incorporates a user model in its’ reasoning process. Most of the research in this area has focused on task-based contextual information when designing systems that reason about interruptions; (2) the classifier performed at 96% accuracy in experimental test scenarios and significantly out-performed other comparable systems; (3) the classifier is implemented using an advanced machine learning technology—an Adaptive Neural-Fuzzy Inference System—this is unique since all other systems use Bayesian Networks or other machine learning tools; (4) the classifier does not require any direct user involvement—in other systems, users must provide interruption annotations while reviewing video sessions so the system can learn; and (5) a promising direction for reasoning about interruptions for free-form tasks–this is largely an unsolved problem

Developing Best Practices for Securing VoIP Communication for a non-profit Organization

Voice over Internet Protocol (VoIP) is the most widely used service around the world. The proficiency of it utilizing the web has increased awesome ubiquity in the current years. With this notoriety, there is expanding worry about the wellbeing of the system. The robbery or loss of the information being exchanged is great concern. For example, a basic problem for researchers who are developing safeguards for VoIP systems is the level of threats and other issues experienced by the non-profit organizations while implementing VoIP communication. This problem originated when non-profits received pressure from their donors not to implement VoIP communication because it will record important and valuable information of their bank account, including their bank balance, and consequently, exposing them to the public. Other dangers include safeguarding secrecy, respectability, and accessibility of the system, known as CIA. dangers. To battle these dangers, some security conventions and calculations have been produced. For example, the H.235 has been investigated, their calculations updated, and it is currently regarded as the most recent and effective system for security of the VoIP system. Another method for battling issues and concerns, and one that is the most proficient due to bigger budgets than non-profits, is VoIP being utilized in new structures and the IT work force. Fortunately, the expanding interest of VoIP has guaranteed and emphasized the requirement for more research to build up the effective security structures and countermeasures of CIA threats. This investigation examines the methods by which such security issues concerning VoIP can be set out to give an appropriate, secure and effective method for correspondence and data trade. In this postulation, the analyst will profoundly examine the relief of VoIP security issues

Improving availability awareness with relationship filtering

Awareness servers provide information about a person to help observers determine whether a person is available for contact. A trade -off exists in these systems: more sources of information, and higher fidelity in those sources, can improve people’s decisions, but each increase in information reduces privacy. In this thesis, we look at whether the type of relationship between the observer and the person being observed can be used to manage this trade-off. We conducted a survey that asked people what amount of information from different sources that they would disclose to seven different relationship types. We found that in more than half of the cases, people would give different amounts of information to different relationships. We then constructed a prototype system and conducted a Wizard of Oz experiment where we took the system into the real world and observed individuals using it. Our results suggest that awareness servers can be improved by allowing finer-grained control than what is currently available
