Persona development : Yun
I love all this new technology. It is great to be see my grandchildren. It takes me a bit to find all the controls and sometimes they are a bit of the small side, but I get there in the end
Yun had a long and successful career as an architect. He delayed retirement until he was in his 70's because work challenged him and as the senior architect in his firm, he was often sought after to mentor the new hires and guest lecture at local universities. Yun always wore glasses but over time, the demands of the close-up work necessary to render architectural drawings strained his eyes to the point that he could only work a couple of hours at a time. The final straw was when he developed a mild hand tremor and found it difficult to maintain the precision required in his line of work.
Currently, at age 85 Yun's vision has continued to deteriorate, his hand tremors have gotten worse, and his family has started to notice some short term memory loss. Even so, yun maintains an active interest in the history of architecture and is part of a small group of people who share his passion and write about it online. His blog has an active following and helps him feel like he can still contribute to the field.
Like many older people, Yun has difficulty reading small text. He stopped buying physical newspapers and now subscribes to an online version now because he is able to increase the size of the text to something he finds easier to read. However, he has had trouble on some sites where this doesn't work so well because either the text gets cut off or the larger text doesn't flow to the next line and he has to scroll horizontally. With his tremor, it's difficult to scroll across in a straight line. Still, however, it's easier than managing the large pages of a print newspaper.
For all of the benefits of using the computer to read the news and stay active in his field, Yun finds CAPTCHAs particularly difficult. These are common when he is signing up to new websites. If the CAPTCHA uses distorted text, he has trouble making it out and if it requires him to select certain images, the pictures are usually not clearly rendered. He's tried using the sound CAPTCHAs but finds them even more difficult even though he has no hearing loss. Yun prefers sites that send him a code that he needs to enter.

Inaccessible CAPTCHA : Problem: When I login to my online banking I need to complete a CAPTCHA but I can't really read it well. : Works well: My banking login sends me a text to with a code to confirm it is me.
Text doesn't reflow : Problem: When I resize a website using my browser some of the text disappears or is cut short and sometimes I have to scroll across the screen as well as down. : Works well: When I resize a website using my browser the text is all still available and is presented in a longer thinner column that doesn't need to be scrolled sideways.
Distracting animations : Problem: When my screen is magnified, animations are very distracting because I don't get the full context of what is going on. : Works well: Allow me to stop any animation on the screen so I can concentrate on what I'm looking at.
Tables don't zoom well : Problem: Online tables sometimes have a lot of space between the columns and when I'm zoomed it, I have scroll from left to right to see all of the content and I often miss the association from one column to the next. : Works well: Make tables to be compact so I can see the information in multiple columns at once without have to scroll horizontally.

Yun is an active 85 year-old with educed vision, hand tremors, and mild memory loss. He has an active interest in art history and is part of a small group who share his passion and write about it online. Yun likes to keep up-to-date with news and current affairs by reading websites. He has also been slowly drawn into different social media platforms that his children and grandchildren use to keep in touch and follow what they are up to.

He has had trouble on some sites where this doesn't work so well; either the text gets cut off or it doesn't reflow and he has to scroll horizontally. When shopping online, this sometimes means that Yun has to search around to find a site that sells what he needs and that he can read easily.
Yun finds CAPTCHAs particularly difficult. These are common when he is signing up to sites. The distorted text is difficult to read and any sound option is unclear. He has had more success with selecting images, but it is often difficult to make out what he is looking at because the image pixelates.
Small controls can be difficult for Yun to target because of his hand tremors. One of Yun's daughters give him a special mouse that helps. This is great when he is using his laptop but not much use when he is using his mobile.
