Security Configuration

End users often find that security configuration interfaces are difficult to use. In this chapter, we explore how application designers can improve the design and evaluation of security configuration interfaces. We use IEEE 802.11 network configuration as a case study. First, we design and implement a configuration interface that guides users through secure network configuration. The key insight is that users have a difficult time translating their security goals into specific feature configurations. Our interface automates the translation from users’ high-level goals to low-level feature configurations. Second, we develop and conduct a user study to compare our interface design with commercially available products. We adapt existing user research methods to sidestep common difficulties in evaluating security applications. Using our configuration interface, non-expert users are able to secure their networks as well as expert users. In general, our research addresses prevalent issues in the design and evaluation of consumer-configured security applications.

This chapter proposes a way of informing creative design of mobile information systems by acknowledging the value of ethnography in HCI and tackling the challenge of transferring that knowledge to interface design. The proposed approach bridges the gap between ethnography and interface design by introducing the activities of field-data informed design sketching, on a high level of abstraction, followed by iterative development of paper-based mock-ups. The outcomes of these two activities can then be used as a starting point for iterative prototype development— in paper or in code. This is particularly useful in situations where mobile HCI designers are faced with challenges of innovation rather than solving well-defined problems and where design must facilitate future rather than current practice. The use of this approach is illustrated through a design case study of a context-aware mobile information system facilitating people socialising in the city.

GPS-enabled mobile maps are now commonly used to wayfind in urban locations. Though increasingly efficient and more widely available, little attention has been paid to how novel approaches to the design of the visual interface may support particular user-experiences. This article presents the results of a practice-based study focusing on the design of an interface which allows walkers to maintain an awareness of the surrounding environment as they wayfind. Through an iterative process, a mixed-fidelity working prototype was developed and tested in a field setting. Results indicate that the interface promoted a high level of awareness of the surrounding environment.

Abstract The most common reason for software product failure is misunderstanding user needs. Analysing and validating user needs before developing a product can allow to prevent such failures. This paper investigates several data-driven techniques for user research and product design through prototyping, customer validation, and usability testing. The authors implemented a case study software product using the proposed techniques, and analyses how the application of UX/UI research techniques affected the development process. The case study results indicate that preliminary UX/UI research before the development reduces the cost of product changes. Moreover, the paper proposes a set of metrics for testing the effectiveness of UX/UI design.

With the continuous development of digitization, the public's understanding of traditional Shu embroidery techniques is increasingly ignored. Through the combination of VR technology and Shu embroidery techniques, it needs to be deeply excavated and inherited. Based on the inheritance and development of Shu embroidery, literature research, user research and case study are used to collect and sort out the current situation of Shu embroidery and its digital inheritance. Around the semiotic characteristics and process flow of Shu embroidery techniques, the interface design and human-computer interaction experience are studied, and the Shu embroidery skill experience area and game interactive experience area are mainly designed. Conclusion the innovative inheritance method of Shu embroidery is developed from the transformation of intangible cultural heritage modernization, and VR advanced science and technology is used to provide reference for the design and research of digital protection platform of Shu embroidery. It is expected that Shu embroidery will inherit well following the development of the times, and then carry forward the traditional technology to the world. Doi: 10.28991/HEF-2020-01-04-01 Full Text: PDF

While the computer vision problem of searching for activities in videos is usually addressed by using discriminative models, their decisions tend to be opaque and difficult for people to understand. We propose a case study of a novel machine learning approach for generative searching and ranking of motion capture activities with visual explanation. Instead of directly ranking videos in the database given a text query, our approach uses a variant of Generative Adversarial Networks (GANs) to generate exemplars based on the query and uses them to search for the activity of interest in a large database. Our model is able to achieve comparable results to its discriminative counterpart, while being able to dynamically generate visual explanations. In addition to our searching and ranking method, we present an explanation interface that enables the user to successfully explore the model’s explanations and its confidence by revealing query-based, model-generated motion capture clips that contributed to the model’s decision. Finally, we conducted a user study with 44 participants to show that by using our model and interface, participants benefit from a deeper understanding of the model’s conceptualization of the search query. We discovered that the XAI system yielded a comparable level of efficiency, accuracy, and user-machine synchronization as its black-box counterpart, if the user exhibited a high level of trust for AI explanation.

Employees and employers are facing issues in work life balance. It has become a difficult domain now, because the work needs have increased due to an increase in work pressure and complexities in handling the technology. As there are drastic changes in the rules and regulations in the work scenario of the aviation industry, it makes work life balance of employees difficult and set more hurdles. Hence there are many distractions and imbalances in the life of women employees in the aviation industry working across all levels. This work pressure is creating high level of hurdles in maintaining a harmonious job and family life, especially for female aviation employees. Data is collected from 50 female crew members working at Cochin International Airport. The objective of this study is to analyze the work life balance of working females of Cochin International Airport and its influence on their personal and specialized lives. The result of the study shows that the management should frame certain policies which will help employees to have the balance among their personal and expert lives.

Building on the existing literature, this study examines whether specific drivers of forest fragmentation cause particular fragmentation characteristics, and how these characteristics can be linked to their effects on forest-dwelling species. This research uses Landsat remote imaging to examine the changing patterns of forests. It focuses on areas which have undergone a high level of a specific fragmentation driver, in particular either agricultural expansion or commodity-driven deforestation. Seven municipalities in the states of Rondônia and Mato Grosso in Brazil are selected as case study areas, as these states experienced a high level of commodity-driven deforestation and agricultural expansion respectively. Land cover maps of each municipality are created using the Geographical Information System software ArcGIS Spatial Analyst extension. The resulting categorical maps are input into Fragstats fragmentation software to calculate quantifiable fragmentation metrics for each municipality. To determine the effects that these characteristics are likely to cause, this study uses a literature review to determine how species traits affect their responses to forest fragmentation. Results indicate that, in areas that underwent agricultural expansion, the remaining forest patches became more complex in shape with longer edges and lost a large amount of core area. This negatively affects species which are either highly dispersive or specialist to core forest habitat. In areas that underwent commodity-driven deforestation, it was more likely that forest patches would become less aggregated and create disjunct core areas. This negatively affects smaller, sedentary animals which do not naturally travel long distances. This study is significant in that it links individual fragmentation drivers to their landscape characteristics, and in turn uses these to predict effects on species with particular traits. This information will prove useful for forest managers, particularly in the case study municipalities examined in this study, in deciding which species require further protection measures. The methodology could be applied to other drivers of forest fragmentation such as forest fires.

Abstract This paper reflects on a case study of a user-centred concept development process for a Machine Learning (ML) based design tool, conducted at an industry partner. The resulting concept uses ML to match graphical user interface elements in sketches on paper to their digital counterparts to create consistent wireframes. A user study (N=20) with a working prototype shows that this concept is preferred by designers, compared to the previous manual procedure. Reflecting on our process and findings we discuss lessons learned for developing ML tools that respect practitioners’ needs and practices.
