The present work proposes the use of information visualization techniques allied to an Augmented Reality user interface to provide in-formation that helps professionals to analyse data, however spatially situated where it was originally measured. This problem and the proposed solution may be adapted into different professional contexts. Three use case visualizations were designed, implemented and testedin the following task contexts: classroom seat analysis, GPS route following and EMC data extraction. Apart from visualizing the situated data, users may also interact with it to narrow down their search by switching the attributes being displayed, combining them together, applying filters, changing its formatting and extracting data from it. The approaches being proposed in this work were tested against each other in comparable 2D and3D interactive visualizations of the same data in a series of usability and performance assessments with users to validate the solutions. The goal was to ultimately expose whether AR can help users to perform better in different decision-making contexts. Our tests exposed relevant results in a series of the variables measured, such as accuracy, correctness, distance travelled and time taken.

Virtual reality (VR) is a fast-growing market that an increased number of organisations are trying to enter by bringing their products into the virtual world. Although extensive research has been done on the design of VR, less research is done on how to move an existing interface into the virtual world. This study aimed to answer the question of how an existing interface can be implemented into a VR environment. In collaboration with the consultant agency Decerno this study has been looking at how an operative system used by brokers can be transitioned. Using research through design methodology, the work has featured interviews with the system’s developers, designing a VR prototype of the operating system and an evaluation of the prototype with the experts. The result generated five guidelines that can be used when attempting to move a 2D interface into the VR world: Take advantage of the volume, Rely on consistency, Use a minimum font size of 23 dmm, 0.75-3.45m between user and screen and interaction using ray-casting.

An estimated 450 million people globally do not have access to a fixed or mobile broadband signal. Recently satellite communication companies announced the concept of Megaconstellations which are large networks of inexpensive low Earth-orbiting satellites. These constellations aim to provide internet access across the planet. Many people believe these constellations will offer an opportunity to bridge the digital divide between developed and developing countries. However, according to the UN development agenda, it is crucial to harmonize three core elements: economic growth, social inclusion, and environmental protection, while achieving the Sustainable Development Goals (SDGs). Although many are enthusiastic about the possibility of closing the digital gap, some researchers have concerns about the environmental impacts of these mega-constellations. Some studies explored howsatellites’ mega-constellations would increase the collision rate among space objects. This by increased amount of space debris which would negatively impact the Low Earth Orbit and the planet and thereby would be inconsistent with environmental sustainability. This study aims to investigate this claim by examining the impacts of future capabilities of satellites on offering inclusive healthcare and education systems while investigating their environmental impacts.

This study discusses the behavior of people towards natural language interfaces. It draws parallels to the behavior of people towards other people, and discusses how far these parallels can be stretched. A small experimental study of users performing tasks using a natural language interface to a database is presented, and the results related to the discussion. The main points made are 1) that new modalities like the one used in typical human computer interaction - written interactive communication - are problematic for new users, from lack of conventions; and 2) that users' attitudes towards computers and of the system's linguistic and other competence shape much of the interaction, and that these attitudes change, and that thus the important factor to take into account in system design is not what the initial attitudes are but rather what the process of changing them is and how to utilize the process of change to teach the user the system language and interaction modality. / <p>QC 20160530</p>

Receiving personal recommendations has today become very common in digital environments. However, little is yet known about how these are perceived by the users directly affected. Previous studies have indicated that attitudes towards personalized content on the internet varies depending under which circumstances they occur. Although people perceive personalization online as beneficial in some cases, there is still a widespread dissatisfaction with the collection of private data. A greater transparency of the gathering and usage of sensitive data has been designated as a necessary step in order for the user to gain more control and increase digital integrity. This study aimed to investigate how increased transparency of private data affects the acceptability of personal recommendations online, that are based on AI-assisted systems. In the current study three chosen domains have been studied: Amusement &amp; entertainment, News &amp; politics and Health &amp; medical care. Potential impact of underlying emotional mechanisms has also will been examined. The participants (N = 498) completed an online survey where transparency of sensitive data was manipulated in two groups as the main independent variable. Acceptance was then measured in subsequent questions, as well as standpoints of emotional and ethical statements related to scenarios for each domain. The hypothesis predicted that the acceptance would increase with added transparency due to more visibility and control of how private data is utilized. However, there will still be a difference between domains where highest acceptance will be measured for amusement &amp; entertainment in relation to news &amp; politics and health &amp; medical care. Based on multiple mixed ANOVAs it can be stated that transparency seems to have a negative effect on acceptance, where acceptance level decreases in all instances with higher transparency for private data. Transparency appears to have the most impact on health and &amp; medical care. The results indicate that emotional reactions follow the same pattern as acceptance, with greater negative feelings for increased transparency and higher positive feelings for low transparency etc. This research reveals interesting relationships between transparency, acceptance and emotional reactions toward personal recommendations which ought to be studied profoundly in the future.

There is a well-known expression that reads: “Communication is key”. That applies to our everyday life, work, relationships and more. Communication helps to make sure everyone is informed, and by doing so, avoiding misunderstandings. Effective and valuable internal communication is also a success factor and an essential part of an organizations’ structure. This study aimed to help staff at the Intensive Care Unit (ICU) at Örnsköldsvik hospital. This paper presents results from a study performed, with the objective to investigate how a digital dashboard should be designed to make management and responsible specialist feel confident that they reach out to all team members and also receives communicated information in a hospital environment. This was done by conducting a user-centered design process to analyze, design and implement a digital dashboard that later on was used in a final study including a test period and evaluation. For a period of 2 weeks, the implemented digital dashboard was tested at the ICU in a hospital. After that period, the dashboard was evaluated by the staff members using a questionnaire, and an interview with the responsible administrator of content. The result suggest that the management and responsible specialist felt that the digital dashboard makes them reach out to all other team members better, compared to their current communication channels. In addition, the vast majority of team members felt that they receive communicated information better. By using a digital dashboard as an internal communication platform, information exchange within the staff at the ICU was improved. / <p></p><p></p><p></p><p></p><p></p><p></p><p></p><p></p><p></p><p></p>
