    UIAAC: a method for design of graphical user interface for augmentative and alternative communication
    (SciTePress Digital Library (Science and Technology Publications, Lda), 2021) Prado Cabrera, Katerine Daniela; Cedillo Orellana, Irene Priscila; Sánchez Sánchez, William Andrés; Collaguazo Malla, Christian Xavier
    The world's population is aging, which is reflected in the increased proportion of older adults, both in developed and developing countries. In 2019, 1 in 11 people exceeded 65 years old; and it is projected that by 2050, this proportion will be 1 in 6 people. Among the most common problems older adults face are those linked to physical, auditory, and visual impairment and, affect, the way they communicate and interact with others. While the usual way of communication is through speech, 1.3% do not depend on verbal language, and as a result, their communication needs are not met. Therefore, it is necessary to search for other modes of communication (apart from speech), which are used to express thoughts, needs, desires, and ideas. An option is Augmentative and Alternative Communication (AAC), which presents methods and technology to help people develop or regain communication ability. Thus, this document presents a method called UIAAC, which aims to facilitate the design of graphical user interfaces for AAC systems oriented to older adults and incorporate pictograms as a means of communication. The presented method is aligned with usability standards and considerations of experts in AAC, gerontology, software quality engineers, and user-centered design. To assess the feasibility of the method, the design of a prototype interface and a case study that assesses the perception of the prototype's use is presented. The evaluation was developed from the point of view of the psychological area and the end-user (older adult)

    VitaApp: augmentative and alternative communication system aimed at older adults
    (Springer Verlag, 2021) Cárdenas Delgado, Paúl Esteban; Cedillo Orellana, Irene Priscila; Prado Cabrera, Katerine Daniela; Collaguazo Malla, Christian Xavier; Sánchez Sánchez, William Andrés; Cedillo Orellana, Irene Priscila
    Augmentative and Alternative Communication Systems (AACs) is an important study area for people who need alternative ways to communicate their ideas. An AAC web system based on pictograms for the elderly VitaApp is pre- sented in this paper. The system results from the implementation of the last phase of the UIAAC method, which guides the design and implementation of AAC systems aimed at older adults. VitaApp is based on a client-server architecture, divided into three roles: a) administrator, carer: these oversee customizing the interface and have dedicated web applications; b) elderly: they use the AAC application that their caregiver personalizes for them. The graphical interface of the AAC application is evaluated through a case study that was applied to an older adult, his caregiver, and a clinical psychologist; in this, the ease of use, usefulness, and future use of the web application were evaluated. The results show that its users perceive VitaApp as an alternative communication support tool, useful, easy to use, and considered to be used in the future. © 2021, Springer Nature Switzerland AG.
