A Concept of Usability Assessment for User-Centered Multimedia Applications

Abstract—User-centered activities related to multimedia include production and organization of multimedia content, filing, retrieval, sharing and multimedia communications. Today, there is a growing body of development teams and companies, that work to enable users to perform these activities in various technological ways. Integrating media functions into handheld devices, mobile phones, set-top boxes, and different “wearable ” consumer electronics products, makes users affected in different ways. This paper emphasizes the effects of multimedia applications, which are always on users ’ disposal, on users ’ habits and their regular activities. We argue that application usability is inversely proportional to its usage interference with regular activities of people as users. We introduce novel metrics to capture the amount of this interference, and likewise introduce a measure for multimedia software usability, contributing to software usability assessment processes (SQA).

Methods of implementation of context-aware platforms and context-aware user interfaces for applications in consumer electronics

U okviru disertacije predstavljene su metode realizacije kontekstualnih platformi i kontekstualnih korisničkih sprega za uređaje potrošačke elektronike. Predloženi su algoritmi semantizacije konteksta i procene zauzetosti korisnika, arhitektura rešenja i rezultati evaluacije.  In this dissertation methods of implementation of context-aware platforms and context-aware user interfaces for applications in consumer electronics are presented. The work includes the proposition of algorithms for context semantization and user availability estimation, architecture of the solution as well as the results of evaluation experiments
