Managed Forgetting to Support Information Management and Knowledge Work

Trends like digital transformation even intensify the already overwhelming mass of information knowledge workers face in their daily life. To counter this, we have been investigating knowledge work and information management support measures inspired by human forgetting. In this paper, we give an overview of solutions we have found during the last five years as well as challenges that still need to be tackled. Additionally, we share experiences gained with the prototype of a first forgetful information system used 24/7 in our daily work for the last three years. We also address the untapped potential of more explicated user context as well as features inspired by Memory Inhibition, which is our current focus of research.Comment: 10 pages, 2 figures, preprint, final version to appear in KI - K\"unstliche Intelligenz, Special Issue: Intentional Forgettin

Ethics and Design in the Brazilian Context

Often driven by practical and immediate requirements, more and more people are incorporating technology into a variety of aspects of their lives, often without reflecting on the consequences of using them. On the other hand, studies on interactive system development that lead to behavioral change have been gaining ground on the agenda of large HCI conferences. This movement brings to the forefront the fundamental issues of ethics in design and technology use. A designer’s intentions, when directing certain actions or behaviors, are not always explicit or desired by the stakeholders affected by the use of the technology. Systems that induce an undesired purchase, or even those that use conditioning strategies to cause a behavioral change are examples of such intentions. The challenge proposed is therefore about the relationship between design and personal freedom in a way that these technology users do not become victims, either passively or submissively, of the effects of its use. This advance allows for the redefinition of the relationship between man and technology, and the application of new forms of designing and developing interactive systems that take into account the ethical aspects of this relationship

Training of future teachers of natural sciences for the use of information and communication technologies in their professional activities

Today, an important aspect of future teachers training, in particular, natural sciences, is the usage of innovative technologies and approaches in the educational process of higher education institutions. The features of training future teachers of natural sciences using information and communication technologies are considered. The general global trends in the development of informatization of education are highlighted: expansion of the scope of use new information technologies.The principles of using information and communication technologies in the educational process are highlighted: the principle of visibility; the principle of expediency; the principle of systematicity and consistency; the principle of strength of knowledge; the principle of accessibility; the principle of individualization; the principle of connecting theory with practice; the principle of multimedia; the principle of interactivity. Online tools are highlighted to enable the use of innovative technologies for teaching future teachers of natural sciences. It is noted that in the educational system there are applications and information and communication technologies that widely used in the education system: word supercomputers, databases, demonstration programs, catalogue organization schemes, planners, graphic packages, etc

A Short Message Service (SMS) Based Inquiry System

The arduous tasks of the registrars cause them to overlook undergraduates that inquires in their office – may it be subject deficiencies or requirements. In this study, the researchers developed a software application that can automatically cater inquiries of a student’s status if they have any impending deficiency, and to be able to message students about the precise time of the document’s completion that they have requested. The evaluation result is calculated using Cronbach's Alpha, which displays a value of 0.9053, equivalent to excellent. The ? is determined with the use of the calculated mean of functional sustainability (4.03), reliability (3.88), performance efficiency (3.80), usability (4.03), and security (3.82). The result shows that the system is operational and possesses a quick response that highly benefits the students and the registrar’s office

Evaluating indoor positioning systems in a shopping mall : the lessons learned from the IPIN 2018 competition

The Indoor Positioning and Indoor Navigation (IPIN) conference holds an annual competition in which indoor localization systems from different research groups worldwide are evaluated empirically. The objective of this competition is to establish a systematic evaluation methodology with rigorous metrics both for real-time (on-site) and post-processing (off-site) situations, in a realistic environment unfamiliar to the prototype developers. For the IPIN 2018 conference, this competition was held on September 22nd, 2018, in Atlantis, a large shopping mall in Nantes (France). Four competition tracks (two on-site and two off-site) were designed. They consisted of several 1 km routes traversing several floors of the mall. Along these paths, 180 points were topographically surveyed with a 10 cm accuracy, to serve as ground truth landmarks, combining theodolite measurements, differential global navigation satellite system (GNSS) and 3D scanner systems. 34 teams effectively competed. The accuracy score corresponds to the third quartile (75th percentile) of an error metric that combines the horizontal positioning error and the floor detection. The best results for the on-site tracks showed an accuracy score of 11.70 m (Track 1) and 5.50 m (Track 2), while the best results for the off-site tracks showed an accuracy score of 0.90 m (Track 3) and 1.30 m (Track 4). These results showed that it is possible to obtain high accuracy indoor positioning solutions in large, realistic environments using wearable light-weight sensors without deploying any beacon. This paper describes the organization work of the tracks, analyzes the methodology used to quantify the results, reviews the lessons learned from the competition and discusses its future

Communicating Augmented Reality Devices Improving Technology Acceptance Among Electric Utility Field Workers

Augmented Reality (AR) is very useful for many different fields and purposes such as entertainment, education, military, navigation, industrial, or electric utility. Electric utilities find use in AR due to the flexibility of location and the real-time information sharing with visuals to keep employees safe and efficient. This exploratory study investigated the use of infographic templates as a way to introduce this new technology to line workers in the electric utility field. Infographics were used as a way to prime workers to be more aware of the technology and its possible uses as well as usefulness. Through the use of Communication Accommodation Theory and the Technology Acceptance Model, the researcher found evidence indicating that presenting information in a clear and interesting way increased electric utility workers desire to adopt the new technology through perceived ease of use and perceived usefulness (Davis, Bagozzi & Warshaw, 1989)
