Accessible tourism has become relevant, generating significant economic and social impacts. Even though the accessible tourism market is rising and presents an excellent business opportunity, this market is largely ignored, as it is challenging to stimulate the flow of accessibility information. Accessible technologies, such as tourism information systems, can be a potential solution, increasing accessibility through communication. However, these solutions are few and tend to fail the integration of users upon development processes. This research aims to present a technological platform to improve accessibility in the tourism industry. The name of this accessible and adaptable technological solution is access@tour by action, and it was created following a user-centered design methodology. This development involved a requirement engineering process based on three crucial stakeholders in accessible tourism: educational institutions, supply agents, and demand agents. The design phase was achieved with the help of a conceptual model based on a unified modeling language. The initial prototype of the solution, created in Adobe XD, implements a wide range of informational and accessibility requirements. Some access@tour by action interfaces outline the design, content, and primary functionalities. By linking technological development, tourism, and social inclusion components, this study highlights the relevance and interdisciplinarity of processes in developing accessible information systems.

The right to tourism has become a crucial aspect of society. Through more accessible tourism, it is possible to improve travel conditions for people with disabilities. Nonetheless, barriers still exist, with the lack of information about accessibility conditions representing a main obstacle. Information systems can help overcome these hurdles. However, it is verified that methodologies to support the development of accessible IS are currently very scarce. Thus, this study intends to develop an accessible IS for accessible tourism and propose a roadmap to support the creation of accessible IS solutions. To obtain the intended accessible tourism solution, an action research methodology was followed, which involved adapting already established frameworks, that combine Agile development and user-centered design techniques. Following the methodology, a web application named access@tour by action was created. This mobile solution is capable of improving information management within the accessible tourism market. From this experimental study, a proposal for a methodological roadmap emerged. This roadmap helps to better understand how to develop accessible IS by demonstrating techniques for gathering accessibility requirements and validating them. The roadmap is adaptable and suitable for IS projects involving accessibility. Both results provide a better perspective on how to integrate accessibility during the development of IS, possibly supporting future researchers in creating accessible solutions.
