Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/17680With the increase in life expectancy and the advancement of technology, the elderly public's access to the internet grows together as a means of entering the digital world, a movement accelerated by the COVID-19 pandemic. On the other hand, the conditions inherent to age, such as memory loss, low vision and reduced motor capacity that interfere with learning to use technologies, causing the need to adapt existing technologies in the market. Based on previous studies that analyzed the communicability of WhatsApp from the perspective of the elderly public, this work proposes a medium fidelity prototype of WhatsApp without the need for a final application built by the Figma tool to have the functionalities that allow simulate the necessary elements to evaluate the communicability between the user and the designee based on the Communicability Assessment Method - MAC of Semiotic Engineering to compare the results of the previous work done with the native application and the prototype.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/br/IdososComunicabilidadeWhatsAppRedesingElderlyCommunicabilityDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::METODOLOGIA E TECNICAS DA COMPUTACAO::ENGENHARIA DE SOFTWAREDESENVOLVIMENTO DE SISTEMASCOMPUTAÇÃO APLICADA
