The use of gray tones and colors with low contrast were criticized. The positioning of elements outside one's line
of sight impairs the visualization of information, especially in the case of elderly people, who also have difficulty
perceiving temporary notices on the interface. The same occur on auto-complete functions. They confuse elderly
users who to understand how it operates and perceive secondary actions. The use of the "back" button is still
important due to the lack of function recognition and problems with system’s deep navigation.
We hope that the result of this research will contribute to the development of accessible interfaces with good
usability, compelling designers, developers and managers to take the experiences of elderly users into account, thus
improving access to information on the Internet, web services and mobile apps.
