Identificando barreiras de acessibilidade web em dispositivos móveis: resultados de um estudo de caso orientado pela engenharia de requisitos

The growing demand for mobile devices such as tablets and smartphones, and dissemination of new interactive media through these devices, reveals a new scenario in information access and knowledge. These devices have special features, with challenges regarding accessibility that are present only on these platforms. Requirements Engineering can contribute in this context, identifying requirements that promote accessibility, overcoming currently existing barriers. This paper presents the results of a case study oriented by Requirements Engineering, showing some of these difficulties and how they can be overcome.
