Abstract
The World Health Organization estimates that around 1.3 billion people worldwide are affected by some form of impairment. Ensuring accessibility of mobile applications has become imperative to meet the requirements of this group. Mobile accessibility involves the process of making mobile applications more inclusive for individuals with disabilities using mobile devices. This paper investigates the strong need for effective methodologies to evaluate the accessibility of mobile applications, particularly with the recent implementation of the Web Accessibility Directive in Europe. By reviewing existing research, analyzing monitoring reports from European Union Member States, and conducting interviews with mobile accessibility evaluators, this study identifies limitations in current evaluation methodologies and provides some insights into the challenges faced by evaluators. The findings reveal that there is no universally adopted methodology for evaluating the accessibility of mobile applications. Evaluators either adapt existing methodologies designed for web accessibility or develop their own approaches. The absence of specific guidelines for mobile accessibility poses a challenge, with evaluators often having to interpret web-focused documents. The lack of comprehensive automated tools for mobile accessibility evaluation further complicates the process. Through this research, it is anticipated that improvements in mobile application accessibility evaluations will contribute to creating more inclusive mobile experiences for all individuals.

Abstract
Content generation is a heavy task in virtual worlds design. Procedural content generation techniques aim to agile this process by automating the 3D modelling with some degree of parametrisation. The novelty of this work is the procedural generation of the marine alga (Asparagopsis armata), taking into consideration the underwater environmental factors. The depth and the occlusion were the two parameters in this study to simulate how the alga growth is influenced by the environment where the alga grows. Starting by building a prototype to explore different L-systems categories to model the alga, the stochastic L-systems with parametric features were selected to generate different alga plasticities. Qualitative methods were used to evaluate the designed grammar and alga's animation results by comparing videos and images of the Asparagopsis armata with the computer-generated versions. © 2022 University of West Bohemia.
