Abstract

In recent years, the rapid aging of the Brazilian population has been verified, making the elderly an emerging age group. Parallel to this transformation, the spread of Information and Communication Technologies, particularly the use of mobile devices has been observed. This fact has raised a great interest in the elderly public regarding the use of these devices, considering the benefits they can provide to their lives. This research aims to evaluate the usability of the Siri virtual assistant, available on mobile iPhone devices, with elderly users. The method used in this research proposed three tasks and usability was investigated from the performance analysis based on time and perceptions of the volunteers through questionnaires. Age was found not to be the only factor influencing the usability of the Siri virtual assistant. Other factors, such as prior knowledge, education level and personal motivation, are capable of influencing the research results of usability criteria.
