Justification
● Why Dementia?
○ What is dementia?
○ Why is it important for me?
○ Why is it important in the field of accessible computing?
Analysis
● How did I perform the analysis?
○ ISO/FDIS 9241-171 - Guidance on software accessibility
○ “Issues with Designing Dementia-Friendly Interfaces” - Ancient and Good (2013)
○ “Putting Dementia Into Context” - Vogt et al. (2012)
○ “Research-Derived Web Design Guidelines for Older People” - Kurniawan and Zaphiris
(2005)
○ Other papers
Implementation
● Guidelines from papers and ISO/FDIS 9241-171
○ Based on analysis
○ Regarding people with dementia
○ Some guidelines are left out - Why?
Results
● Guidelines to make systems accessible for people with dementia
● 40 guidelines are established
Some of the important guidelines:
● “The system should provide cues to support recognition rather than
unassisted recall”
○ NOTE Recognition involves the process where the user has seen the feature before
○ NOTE Recall involves fewer cues for memory retrieval, it has to retrieve information from
Results
● “The information on the screen should involve rearranging the information
so that it comes in blocks of one screen’s worth”
○ Avoidance of scroll bars
● “When it is hard for the user to operate with a mouse, the application or
assistive technology should be available on a device that uses touch
screen”
Results
● “The system should increase the readability”
○ Text should be left justified
○ Text lines should be short in length
● “The system should schedule the daily events or activities of the user in
the interface and display reminders, where the reminders are based on the
location where the user is”
Results
● “The system should not be stigmatizing the user”
● Evaluation
○ Based on the teacher’s comments
○ Self-evaluation
○ Examples for the guidelines
Conclusion & Recommendations
● More research is needed
○ Different requirements and different symptoms
● User testing
● Research for guidelines on different platforms
● Artificial Intelligence will help people with dementia
