Abstract In this article, Keystroke Level Model and Touchless Hand Gesture Level Model were adapted, as well as Fitts’s law, to work with touch screens of the mobile devices. The article takes into account typical gestures that users most often perform in the process of interaction with touch screens of mobile devices (Tap, Pinch, Swipe, Pan, Drag-and-Drop), as well as time components of gestures (time for direct execution of a gesture, time for mental preparation for the gesture, time for the user to select the necessary grip on the mobile device, time to select the ‘dominant’ hand to perform gestures, the time to select the finger to perform the gesture, time to move the hand away from the touch screen). A method for determining the speed of user gesture interaction has been developed. The problem was formulated and an algorithm was developed. The details of the operation and use of the algorithm are considered. A list of arrays and variables used as initial data for determining the speed of the sequence execution of operations using gesture interaction has been developed. The preparation of the initial data for the operation of the algorithm provides for a research experiment to obtain average values of the temporal components of gestures. The developed algorithm is intended for use at the design stage of mobile software applications that will run on mobile devices with touch screens.

Requirement Prioritization

Mobile software application development process must be matured enough to handle the challenges (especially market related) associated with the development of high quality mobile software development. Ever increasing number of both mobile users and mobile applications had presented software engineers with the challenge of satisfying billions of users with high quality software applications to be delivered within deadline and budgets. Always there had been a lot of pressure to develop complex software categorized by thousands of requirements, under resource constrained environment. Requirement prioritization is one of the activities undertaken by software engineer to deliver partial software product to its customers such that most important requirements are implemented in the earliest releases. During next releases some changed and pending requirements are implemented, an activity that generates ripple effects. Such ripple effects need to be tested by executing modified source code against test cases of previous releases (regression testing). Regression testing is a very effortful activity that requires a software tester to select test cases that have high fault detection capability, execute the modified code against selected test cases and performing debugging. This regression testing activity can be lowered to the maximum extend by considering dependencies between requirements during the time of requirement prioritization. Thus requirement prioritization will be carried out not only against aspects like cost, time, risks, business values etc but against dependencies also. The aim is to implement almost all dependent highest priority requirements in current release so that implementation of new requirements is unlikely to have ripple effects. Changes in requirements might not be related to variable usage and definition and might not involve a change in functionality. In such cases there is no need to select already executed test cases of previous versions. Module dependencies can lead to test case selections of previous versions if changes of requirement lead to ripple effects. This paper aims to implement highest priority requirements such that regression testing is performed to minimum thereby improving development process of mobile applications. The proposed technique had been successfully evaluated on Android based notification software application that meets the specification of Aakash tablets.

The worldwide explosion in popularity of mobile devices has created a dramatic increase in mobile software (apps) that are quick and easy to find and install, cheap, disposable, and usually single purpose. Hence, teachers need an equally streamlined and simplified decision-making process to help them identify educational apps—an approach that differs from traditional technology decision-making approaches that are cumbersome and require significant time, resources, and effort. Project Software Identification and Evaluation for Decision-Making (SIED) attempts to fill this gap. In this article, we describe Project SIED, how we designed a series of professional development workshops for in-service special education teachers based on Project SIED, and the evaluation outcomes of the workshops. Results suggest that workshops were successful from in-service special education teachers’ self-reported confidence and comfort levels. Limitations and future plans are discussed.

The main objective of this article was to identify the conditions for the use of smartphones and mobile applications in Poland in the second half of 2018. The scope of the present analysis was limited to a selected sample of more than 470 respondents, and it examined the group of the most active users of smartphones and mobile applications. The author adopted the CAWI (computer associated web interview) method, which was previously verified by a randomly selected pilot sample, in his study. The obtained results were compared with the findings of other studies. They indicated that users of smartphones and mobile applications in Poland do not differ in their assessments from users in Europe and around the world. In this context, the key implication for researchers is the identified level of development of the use of smartphones and mobile applications in Poland at the end of 2018. The main limitation of the research was the selection of the research sample, which consisted only of members of the academic community. The scope of this article aimed to fill a gap in terms of the quantitative and qualitative methods that are applied to examine the use of mobile devices and mobile software. At the same time, this study creates the foundations for further research on intercultural differences. It is important to note that the present research sample needs to be extended beyond the academic community for the research results to be fully generalized.

The paper describes the application of augmented reality tools to create an auxiliary interactive tool in the field of design. To mediate it, an application with AR operation based on marker tracking has been designed. The created application works with the mobile devices platform. Two types of markers have been used in the application. To display basic information, buttons with functions are added to the scene, such as part information, rotation and change of position in the X, Y, Z direction. The application runs on a mobile phone, with a built-in camera. The marker is displayed in the drawing's lower left corner. The model is positioned so that it appears above the view of the part in the drawing. The task of the application is to support intelligent tools applicable in the design stage of production preparation, in the creation of drawing documentation.

In this paper a novel and significant study into the usability of carousel interaction in the context of desktop interaction is presented. Two equivalent prototypes in an e-commerce context were developed. One version had a carousel and the other version did not have a carousel. These were then compared with each other in an empirical experiment with 40 participants. The data collected were statistically analysed and overall results showed that in terms of performance the Web site version without carousel outperformed the version with carousel. Furthermore, the subjective preferences of the participants were strongly in favour of the without carousel version of the site. The results of this study make an important contribution to knowledge suggesting that in many cases implementing a carousel is not the best design decision. The results of this paper are particularly significant in relation to desktop versioned Web sites and goal-driven tasks. Serendipitous-type tasks and mobile versioned web sites used on mobile devices with touch screens were not part of the scope of this work.
