Abstract

Accessibility is a central concept to enable people with different types of limitations to perceive, understand, navigate, interact and contribute in information systems. People with disabilities are generally weakened, or even unable to use computer systems in their fullness due to barriers in these systems. The context of socio-enactive systems represents a totally new and extremely complex scenario for treating accessibility by involving a multiplicity of devices and senses, combined in dynamic situations of use and effects of that use in an individual and social dimension. For example, scenario 1 described in the thematic project, related to the musical table, illustrates the case of a deaf student, in which the solution of the system should contemplate means to include this student and enable him to experiment and interact with the system through alternative media that explore their different senses. A key issue is to enable accessible interaction with systems including new modes of interaction (tangible, wearable and natural interfaces) in contexts of great diversity of people. Such an issue requires in-depth research and conceptual, experimental, and practical contributions. While the concept and techniques for designing more accessible systems have been extensively studied in the context of web systems that make use of simpler features, researches are less developed in complex scenarios that dynamically link human and technological processes. Our goal is to conduct a detailed research proposing a systemic approach to foster accessibility in socio-enactive systems. In our methodology, we first propose the effective participation of users in experiments to analyze several aspects related to accessibility in the use of socio-enactive systems. We will examine the limits of traditional accessibility recommendations in this context. Secondly, it is proposed to define a set of original recommendations based on new techniques and methods that guide the application of the recommendations in the design of accessible interactive mechanisms in socio-enative systems. We aim to study several aspects about how to integrate diverse media as a means of making accessibility possible and the effects of using them. This plan proposes to carry out experimental validations to evaluate the developed methods and prototypes implemented in scenarios of practical applications in socio-enative systems. It is expected to achieve relevant scientific and technological results, including advances in the knowledge about the problem, new recommendations, techniques, methods and computational mechanisms that will allow the interaction of users taking into account their differences, thus removing the barriers in the use of these systems by disabled people. Results achieved will be disseminated in periodicals and qualified scientific events. (AU)
