As stated by the Brazilian Computer Society, the ‘participative and universal access to knowledge’ is one of the grand challenges in computer science research. In this work we describe our attempt to address this challenge of designing automated digital solutions in the environment of a public agency of an electric energy utility company. The potential users include the blind, deaf, low vision, low literate, elderly, young, and digital experts or not. The main contribution of this paper is the proposal of a participatory practice that anticipates the communication problems that might occur when this diversity of users are gathered to interact collaboratively in a same activity. We point out the lessons learned from this experience, which might guide other practitioners and designers.
