Smart doorbell: An ICT solution to enhance inclusion of disabled people

In daily life, people have the need to know the identity of a visitor who comes to their homes, regardless of whether they are there at that time. This need is even greater for people who suffer from some kind of disability that prevents them from meeting the visitor. To provide a solution in this sense, this paper proposes a smart model that performs the task of a doorbell, which should recognize the visitor and alert the user. To achieve that, this proposal incorporates technologies for facial recognition of people, notifications to users and management of their responses. The process to solve the problem was divided into interrelated stages and standardization issues are discussed later. Finally, to test the effectiveness of the model, three scenarios were simulated; each one was composed by different households over which the recognition of known and unknown individuals was analyzed.
