Quality of sound is one of the most important factors while choosing the perfect smartphone model. This article concerns about domestic sound testing of smartphones. Both ways of examining and the equipment used for it are discussed. These tests have been performed on popular models of smarphones: Galaxy S6, iPhone 6S and Lumia 950 to collect recent data and to achieve the essential aim: establishing the fact which model is the best in terms of sound processing.

During the motion registration using passive motion capture system in the marker’s trajectory a gap may appear, which in the data post-processing should be filled in. Various interpolation algorithms are used for this purpose. This article presents three different interpolation methods: linear, polynomial of Lagrange of second degree and fifth degree. In the original 3D data the holes have been created, which are then filled in by mentioned methods. Each method was evaluated by measuring the Euklides distance for three dimensions of the original and interpolated data. The article presents the program to interpolate gaps in the trajectory, implemented in C ++ language. The analysis concerns the interpolation of selected marker’s trajectory which belongs to the Plug-in Gait model while performing walking.

Article presents comparative analysis of jQuery Mobile library and Bootstrap framework in responsive site development. The comparative based on two websites, made in these technologies. Criterions of analysis are: compatibility of mobile devices, prepared components, loading speed on different devices, code size and compatibility with W3C and Google standards. Both technologies in a large degree helps in process of websites development, although jQuery Mobile is more expanded.

The subject of this article is a comparative analysis of some of the most popular frameworks, of JavaScript programming language, dedicated to creating Single Page Applications. There were four criteria accepted for the purpose of the research. The criteria are: difficulty of learning the given library, additional tools specific for given framework, performance on desktop devices and performance on mobile devices.

The paper presents research on the applying augmented reality technology in the process of knowledge assimilation by pupils. The study was conducted with the use of dedicated educational mobile application. The application takes the form of a quiz, where 3D objects represent answers. The aim of the analysis is to confirm the thesis that the augmented reality applied in mobile applications helps in learning new contents. Preliminary survey and the analysis of achieved users results confirmed the thesis.

This publication presents chosen forms of data persistence such as: Local Storage, Shared Preferences, flat files and SQLite in the context of two widely used mobile operating systems – Android and Windows Mobile. It also describes ways to connect to external database engines such as Microsoft SQL Server, PostgreSQL or MySQL and tries to answer the question which one of these data persistence forms makes the most sense and when. The arguments are based on performance tests that all of the described solutions were participants of.
