From 24.01. to 29.01.2010, the Dagstuhl Seminar 10042 ``Semantic Challenges in Sensor Networks \u27\u27 was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

Usability analysis of contending electronic health record systems

In this paper, we report measured usability of two leading EHR systems during procurement. A total of 18 users participated in paired-usability testing of three scenarios: ordering and managing medications by an outpatient physician, medicine administration by an inpatient nurse and scheduling of appointments by nursing staff. Data for audio, screen capture, satisfaction rating, task success and errors made was collected during testing. We found a clear difference between the systems for percentage of successfully completed tasks, two different satisfaction measures and perceived learnability when looking at the results over all scenarios. We conclude that usability should be evaluated during procurement and the difference in usability between systems could be revealed even with fewer measures than were used in our study. © 2019 American Psychological Association Inc.

Identifying principles of human-computer interface in IOT devices : a South African context

Dissertation (MCom (Informatics))--University of Pretoria, 2022.With an increasing number of households implementing smart home technology in South Africa, it is important to understand if the Internet of Things (IoT) devices are enhancing the user’s quality of life as well as meeting their needs and expectations. Identifying and incorporating the Human–Computer Interaction (HCI) component when building an IoT device can assist with ensuring that the smart device meets the useability requirement and addresses the challenges and concerns raised by end users. As the end user is required to install and manage the smart device by themselves, the smart device manufacturers must ensure that these devices are easy to set up and can be managed by both technical and non-technical users. IoT devices require data to be fully functional and perform their necessary tasks. IoT data collection is an ongoing discussion as the end user might not be entirely comfortable with the collection and sharing of their personal home data with device manufacturers. HCI designers, therefore, are required to consider end users' emotions regarding their security concerns. Hence, the purpose of this research is to study the principles of HCI in an IoT device. The objective is to add to the existing body of knowledge related to building computation devices around HCI principles. This interpretive case study used two qualitative data collection methods to answer the research questions: a questionnaire and semi-structured interviews. The questionnaire focused on gathering insights into the current user experience with smart home devices and identifying challenges or concerns raised by the device users. The semi-structured interviews focused on gathering information on the inclusion of HCI when designing an IoT device, IoT data and the IoT security element, from the employees of the organisation in the case study. The research findings indicated that while the participants have adapted to installing and managing their smart home devices, there were several usage challenges and concerns Page 2 of 146 that need to be addressed. Several of the research participants were unaware of the smart device collecting usage data and therefore, the requirement to educate end users on data collection and usage is highlighted in the study. Key design components of the IoT were highlighted by the interview participants and several methods were also suggested to enhance the user experience of IoT devices.InformaticsMCom (Informatics)Unrestricte

Swarming Reconnaissance Using Unmanned Aerial Vehicles in a Parallel Discrete Event Simulation

Current military affairs indicate that future military warfare requires safer, more accurate, and more fault-tolerant weapons systems. Unmanned Aerial Vehicles (UAV) are one answer to this military requirement. Technology in the UAV arena is moving toward smaller and more capable systems and is becoming available at a fraction of the cost. Exploiting the advances in these miniaturized flying vehicles is the aim of this research. How are the UAVs employed for the future military? The concept of operations for a micro-UAV system is adopted from nature from the appearance of flocking birds, movement of a school of fish, and swarming bees among others. All of these natural phenomena have a common thread: a global action resulting from many small individual actions. This emergent behavior is the aggregate result of many simple interactions occurring within the flock, school, or swarm. In a similar manner, a more robust weapon system uses emergent behavior resulting in no weakest link because the system itself is made up of simple interactions by hundreds or thousands of homogeneous UAVs. The global system in this research is referred to as a swarm. Losing one or a few individual unmanned vehicles would not dramatically impact the swarms ability to complete the mission or cause harm to any human operator. Swarming reconnaissance is the emergent behavior of swarms to perform a reconnaissance operation. An in-depth look at the design of a reconnaissance swarming mission is studied. A taxonomy of passive reconnaissance applications is developed to address feasibility. Evaluation of algorithms for swarm movement, communication, sensor input/analysis, targeting, and network topology result in priorities of each model\u27s desired features. After a thorough selection process of available implementations, a subset of those models are integrated and built upon resulting in a simulation that explores the innovations of swarming UAVs

Cumulative index to NASA Tech Briefs, 1986-1990, volumes 10-14

Tech Briefs are short announcements of new technology derived from the R&D activities of the National Aeronautics and Space Administration. These briefs emphasize information considered likely to be transferrable across industrial, regional, or disciplinary lines and are issued to encourage commercial application. This cumulative index of Tech Briefs contains abstracts and four indexes (subject, personal author, originating center, and Tech Brief number) and covers the period 1986 to 1990. The abstract section is organized by the following subject categories: electronic components and circuits, electronic systems, physical sciences, materials, computer programs, life sciences, mechanics, machinery, fabrication technology, and mathematics and information sciences
