RESUMO:

Technological solutions have increasingly been incorporated into our daily lives and our homes. Such technologies have included smart devices and more advanced appliances, including equipment supporting IoT (Internet of Things). Smart homes consist of home control technologies that seek to automate daily activities, such as turning on lights and controlling equipment. Smart homes have the potential to provide greater accessibility to perform tasks by people with disabilities.

Among these people, visually impaired people substantially benefited by smart homes.
With smart homes, people with visual impairments can obtain detailed information about the
environment and easier control of activities. Considering the limitations in the use of visual
elements, multimodal interfaces can further improve the accessibility of smart homes to people
with visual impairments. With diverse modes of interaction, the system user can adapt the
controls to users’ needs and provide for a better experience. Thus, this project aimed to explore
the multimodality of interaction in smart homes accessible to people with visual impairments,
to extract design recommendations for the development of smart home interfaces. For that, the
research followed the methodology of Quiñones et al. to generate the design recommendations.
The research encompassed three data sources to inform the process of generating the recommendations:
1) a systematic mapping of studies about the accessibility of smart homes to people
with visual impairment; a survey of requirements for smart home systems through awareness
videos and interviews with visually impaired people; and exploratory usability evaluation on a
prototype smart home with ten visually impaired users. The results of the mapping study revealed
a low number of studies involving exclusively visually impaired users, in addition to the
lack of guidelines for the development of smart homes. The requirements survey revealed the
obstacles and challenges encountered by people in their daily activities. Several appliances do
not have accessibility for use, which makes users find it difficult to use. It also highlighted the
preferences and desires with smart home technologies, such as low cost, basic accessibility and
ease of learning. The results of the usability evaluation of the prototype showed which practices
and strategies allowed the user to have a better user experience. They also demonstrated
the need for systems with minimalist, self-explanatory interfaces and navigation shortcuts for
users. With the data from these studies, it was possible to extract eight design recommendations
relevant to the development of multimodal smart homes for people with visual impairments.
The recommendations defined in this study are of great importance to assist in the development
of more accessible multimodal applications for the control of smart homes by people with visual
impairments.
