Human-centered: start from practices and (unmet needs):
What is interesting is how they started from observations of elderly relatives and their everyday practices, and how they might be impacted by old age:
"We started this project from personal experiences with our elderly relatives as well as observations stemming from them," the pair tells Co.Design. "For instance, Francesca’s grandmother could not bring the daily coffee to her grandfather when she lost some mobility, and it made her sad. So Francesca thought why not make a walking aid for her that allowed her to continue this life ritual."
Balancing functionality and needs:
This is an interesting quote about the balance between functionality and "not losing face" (emotions related to status and not looking old or infirm):
"We feel that the range of products should not be any different from the possessions that we have consciously selected according to our tastes and preferences up to the point of needing these aid objects"
Universal design principle: "In fact, the designers joke, "considering our acquired laziness from our increasingly sedentary lifestyles and bad eye sight from staring at our devices’ screens," one can appreciate them just as much in their 20s as in their 80s."
