Abstract

The Augmentative and Alternative Communication Systems (AACS), by means of symbols selections, help to develop communication and reduce the frustration of those people who have difficulty in speaking. In order to inspect the usability of this type of system, it can be used the Nielsen's Heuristics. However, these are for general use and do not consider the peculiarities of this class of systems. In this context, since no related proposals were found, the customization of the Nielsen's Heuristics for the domain of AACS is presented in this article. That is, a guideline of 69 (sixty-nine) good practice of usability for AACS has been produced. This guideline can be used by professionals (researchers and practitioners) who need to inspect existing AACS, or to design new AACS. The proposed guideline were produced and evaluated by 05 (five) AAC professionals, who were guided by 01 (one) usability professional. The results obtained reinforce the hypothesis that, although the Nielsen's heuristics consider important criteria of usability, they do not address specific problems of the AACS, which can compromise the usability inspection of this class of systems.

自定义可用性启发式辅助和替代通信系统

辅助和替代沟通系统(AACS)通过选择符号，帮助发展沟通，减少说话困难人士的挫折感。为了检验这类系统的可用性，可以使用尼尔森启发式。然而，这些都是通用的，并没有考虑这类系统的特性。在这种情况下，由于没有找到相关的建议，因此本文提出了针对AACS领域的尼尔森启发式定制。也就是说，已经为AACS提供了69(69)个可用性良好实践的指导方针。本指南可供需要检查现有AACS或设计新AACS的专业人员(研究人员和从业人员)使用。建议的指南由05(5)名AAC专业人员制作和评估，他们由01(1)名可用性专业人员指导。获得的结果强化了假设，尽管尼尔森启发式考虑了可用性的重要标准，但它们没有解决AACS的具体问题，这可能会损害这类系统的可用性检查。
