Usable privacy and security has become a significant area of interest for many people in both industry and academia. A better understanding of the knowledge and motivation is an important factor in the design of privacy and security tools. However, users of these tools are a heterogeneous group, and many past studies of user characteristics in the security and privacy domain have looked only at a small subset of factors to define differences between groups of users. The goal of this research is to critically look at the difference between people, their opinions and habits when it comes to issues of privacy and security. To address this goal, 32 in-depth qualitative interviews were conducted and analyzed to look at the heterogenous nature of this community. The participant’s attitudes and actions around the dimensions of knowledge about tools and of motivation for self-protection were used to cluster participants. The traits of these participant clusters are used to create a set of privacy and security personas, or prototypical privacy and security tool users. These personas are a tool for incorporating a broader understanding of the diversity of users into the design of privacy and security tools.

The rapid economical and social changes in Lithuania induce the changes of professional life: the increase of planning need in professional career, professional activities changes, the demands for worker’s personality. Democratic society needs professionals, who gal quickly adapt to changeable conditions, full of initiative, self-confidant, seeks for higher professional standards, are responsible, expand or extend their professional know ledges and abilities. (Navaitiene, 2000). The aim of our work was to investigate the competence of technology teachers, training critically thinking user. The investigation took place in 2005 February – March, in Vilnius (In teacher’s professional development center), in Trakai and Vilkaviskis districts schools. 120 technology teachers took part in the investigation. The analysis of literature showed that the training of users takes important place in technology training; there is still duration of competence teachers, who can train nowadays user. The competence of a teacher in science literature is shown as an ability to influence the conditional knowledge of individuals, skills, practices, points of view, personal qualities and values. In the work of a competence teacher exposes natural and acquired characteristics, general skills (such as: intellectual, communicational, abdicated, empathic, diagnostically, organizational, expressive) importance. The training of users induces the rational choice and constructive... [to full text]

One of main task in information system development is to project good graphical user interface. It is used many different methods, tools and princess for automatic user interface generation. ODRES (output driven requirements engineering) method witch is developed in the department of information system has an ability to generate graphical user interface from its user developed specifications. These specifications are stored in specification storage – database and they are strictly defined. The tool used to generate graphical user interface from selected ODRES storage reads those specifications and transforms them into graphical elements. An engineer can change those elements. At the end of generation user interface prototype is saved in the same specifications storage.

Mobile devices are frequently used to view rich content while on the go. However, they have a tradeoff between increased screen size and portability; mobile devices, by definition, are constrained to a fraction of a desktop computer’s display area. This constraint means a user has to frequently navigate to content that lies outside the display. We present FlexView, a prototype system and set of interaction techniques, which allows users to navigate through depth-arranged large information spaces using display curvature as an additional input channel. FlexView augments the planar (X-Y) navigation currently performed by touch input with two forms of bend input to navigate through depth (Z). With leafing, the user holds one side of display and bends the opposite side. Squeezing involves gripping the display in one hand and applying pressure on both sides to create concave or convex curvatures, and supports concurrent interaction with touch input. We performed two evaluations to investigate the performance of FlexView’s interaction techniques. In Experiment 1, we measured the efficiency of participants when searching through pages of a document, and compared touch input to squeezing and leafing used in isolation. Experiment 2 introduced X-Y navigation in a pan-and-zoom pointing task where multi-touch pinch gestures were compared against squeezing and leafing for zoom operations. Panning, across all conditions, was performed with touch input using the index finger. Our experiments demonstrated that touch and bend interactions are comparable for navigation through depth-arranged content, and squeezing to zoom recorded the fastest times in the pan-and-zoom pointing task. Overall, FlexView allows users to easily browse depth-arranged information spaces without sacrificing traditional touch interactions. / Thesis (Master, Computing) -- Queen's University, 2012-09-10 13:28:18.984
