Abstract:

Thirty-six websites designed for older adults were evaluated as to how well they complied to 25 'senior-friendly' guidelines recommended by the National Institute of Aging. Results indicate that a majority of the sites complied to guidelines related to basic navigation and content style but not for text size, text weight, or site map availability. Implications of compliance to these guidelines on user satisfaction and performance are discussed.
