The Web can be understood as an ecosystem of interconnected technological resources organized by rules, strategies, organizational structures, and mainly people. Such ecosystem is improving the potential to access knowledge everywhere and at any time. However, for different reasons, this technological extension is not reaching everybody yet. Those without access to knowledge are mainly people with disabilities or living in underserved communities. Nevertheless, the extension of Web technologies to different types of devices (such as mobile phones, tablets, TV) and their connections have the potential to increase the solutions to reach people with different needs through different devices. For this reason, several research and industrial studies have been proposed to design interfaces for multiple devices considering differences among users. In this paper, we present results of a systematic review on literature to build a roadmap towards inclusive environments. Additionally, the study also suggests existing tools to support the design of accessible applications for multiple devices. A significant result of this review is the lack of studies addressing underserved communities.
