Audio fading is performed in order to smoothly modify over time the level of an audio signal. In particular, the fade-in audio effect designates a gradually increase in the audio volume, starting from silence. In practice, audio fading is mostly carried out within audio editors i.e. in off-line mode by employing various transcendental functions to enforce the fade profile. Taking into account the increasing demand for interactive media services requiring real-time audio processing, the present approach advances an effective method of constructing the audio fade-in shape with a view to real-time computing. The paper encompasses plain and straightforward implementations in pure JavaScript, prepared precisely to validate the method of audio volume processing proposed here.

The fade-out sound effect designates a strict decreasing of the volume of an audio signal, starting from the detected initial level down to silence. Audio fade-outs are usually processed in off-line mode that is within audio editors, by employing different transcendental functions to set the time-related evolution of the audio level. However, the proliferation of mobile devices as well as the increasing popularity of web applications, implemented in HTML5/JavaScript, press for computing techniques suitable for real-time processing. In this context, having in view that the computation of the outputs of transcendental functions is very time-consuming, in order to construct the audio fade-out profile, a technique suitable for real-time computing is developed in the present investigation. The suggested techni-que is validated by means of an implementation in pure JavaScript, put forward with the purpose of immediate testing.

Since paradigm shift from thick clients to thin ones and through growing requisition of remote services we have been facing continuous evolution of web applications. Standards and approaches of building HTML clients have been changing and now one of the biggest challenges for web application developers is issue related to clientside data storage. This paper applies to new technologies specified recently by World Wide Web Consortium. These specifications refer to new methods of storing data in web clients, which can be accessed via JavaScript in modern web browsers. In addition, the paper introduces a design and a reference implementation of a framework for Java language and Java Server Pages technology that simplifies implementation of web based applications with client-side storage. The framework is designed for integrating Java language with above mentioned new W3C specifications to create more powerful, modern, thin client web applications easily, without a need of knowledge of implementation details of JavaScript API for new technologies but using only Java language. The framework can be used to build thin clients, including mobile web-based clients that may replace not –portable, native mobile applications.

In the paper, the subsystem for graphical visualization of semantic messages has been proposed and configuration dataflow has been described. The key problem in 3D object rendering over video camera image is fusion of parameters collected during camera calibration and pose estimation with models of visualized objects. Pose estimation results and transformation matrix setup were described. Proposed system has been developed in HTML5 internet web page format that uses portable JavaScript language and WebGL library that make use of GPU device. Presented prototype can be used by a web browser on desktop PC as well as on mobile device. No third-party software is necessary.

Poziom rozwoju standardu HTML5 jest na tyle dojrzały, że coraz więcej przeglądarek WWW jest kompatybilnych, w różnym stopniu, z HTML5 i w ślad za tym rozwijane są aplikacje i treści w HTML5. W swych zapisach standard HTML5 wydaje się idealnym środowiskiem efektywnego tworzenia m.in. interaktywnych multimedialnych treści szkoleniowych dostępnych, po opublikowaniu, z różnych urządzeń mobilnych. Istnieją jednak bariery w zastosowaniu tych możliwości HTML5, które mogłyby ułatwić tworzenie interaktywnych szkoleń i umożliwić udostępnianie ich dla wszystkich platform mobilnych. Artykuł przedstawia potrzeby i oczekiwania rynku odbiorców szkoleń mobilnych, cechy i praktyczne możliwości HTML5 w porównaniu z Flash w odniesieniu do interaktywnych, multimedialnych szkoleń mobilnych. W artykule również zostały omówione stosowane obecnie techniki tworzenia i udostępniania interaktywnych szkoleń multimedialnych na urządzeniach mobilnych.

Level of development of the HTML5 standard is mature enough that more and more browsers are compatible, in different degrees, with HTML5. and consequently the applications are being developed and content in HTML5. From the specifications the standard HTML5 seems an ideal environment to efficiently create interactive multimedia mobile content available after publication on a different mobile devices. However, there are barriers to the use of these opportunities HTML5, which could facilitate the development of interactive video and allow them to share for all mobile platforms. This paper presents the needs and expectations of the market of mobile training audience, features and practical possibilities HTML5 compared do Flash for mobile multimedia content. The article also discusses the currently used techniques for development and sharing interactive training on mobile devices.
