Designing universal solutions for touchscreen interfaces that are accessible to the greatest extent of the population as possible constitute a challenge for most designers. In this paper we discuss an interaction model that addresses this challenge in a universal and participatory way. In the context of public self-service kiosks, we combined two successful solutions -- CPqD Alcance and STID -- into one to make touchscreens accessible in the universal design.
