3. Process 1. Literature Studies 2. Functional Accessibility Evaluation 3. Survey Questionnaire 4. Focus group interviews 5. Information Architecture 6. Redesign Suggestions

10. Findings from Questionnaires 6. Determining in text is a link might be confusing 7. Advertisements and pop ups can be very frustrating.
11. Findings from Focus group 1. Older adults not completely averse to Internet 2. Prefer a simple, uncluttered and easy to navigate website 3. Key features of website should be conspicuous with support for guidance 4. Trust a travel agent more than travel websites
12. We identified key areas of the website that needed improvement Design improvements Help? How do we use the website? What is more?
13. Redesign Suggestions Addition of drop-down menu on hover on "More" menu item improves visibility of previously hidden options
14. Addition of easily accessible and descriptive help options that were previously missing
15. A step-by-step guided tour by clicking button "Learn How it works"
16. Visibility of the system status. Shows exact number of steps in the process for unfamiliar users.
17. No default selections. If the user chooses, they can check the options. Default selections cause spam-like popups which confuse and irritate users
18. Add "alt text" to image tags The FAE revealed that images in Kayak lacked alt text. A visually impaired older adult using a screen reader will hear the alt text in place of the image
19. THANK YOU
