Burn Taboos?
Many people with and without vision loss, felt they shouldn't talk about first and / or second degree burns they received while cooking since they didn't result in hospital trips or treatment.
Demographics
- Approximately 8.3 million Americans with vision loss are poor or near poor
- Of 21.2 million Americal adults, 12.5 million women and 8.7 million men report experiencing significant vision loss
- On average, 2/3 of people 65 and older report some vision loss
Nutrition
- A healthy died consists of vegetables and whole grains
- With the population of visually impaired poor or near poor as well as elderly, pasta, beans and vegetables are ideal, low cost, quick & easy to cook and provide needed nutrients
- Being able to steam and cook vegetables is key for older people who may also have teeth problems
User Interviews & Observational Research
Burns
"I haven't received a {bad] burn while cooking, just those ones that go aways in about 2 weeks."
Fatigue
"Forgetting which pots and pans are heated [can] be difficult, especially keeping track of hot handles."
"Draining water is so difficult, I just fish out my food and let the water cool."
Fear
"I don't cook very much because I am afraid of burns but I want to start cooking, it sounds fun and I think once I start, it won't be scary."
"It is scary to be near heat when you can't see"
Personal Experience
Cooking with safety glasses smeared in vaseline, for a month, to simulate low vision. Goal was to gain empathy and better understanding of physics and emotional hurdles associatied with cooking with low vision.
Key Takeaways
- Lack of depth of field made searching for handles, utensils and food difficult and nerve racking
- Getting hit with little bits of oil was not only painful but scary, not knowing how far away from the pot you are or where the handle is was never racking because you didn't want to knock over the pan or make sudden movements
- It was extremely difficult to know when the food was done, resulting over cooked, hard, crispy burnt food

FINAL DESIGN
Black shell & lid used on white stoves, white shell & lid used on black stoves for best contrast.
Various handle, lid & pot rim colors available.
Safe Cooking Cookware
A cooking pot for the visually impaired that promote self reliance and confidence.
This multi-functional cooking pot consists of 4 parts. There is a ceramic shell outside which limits surface heat and a metal pot insert with a silicon rim for safe touching. The vented lid helps contain boil overs. And the 2-in-1 steamer/ strainer allows users to cook a larger variety of food while reducing effort and utensils needed.
High contrast colors identify parts and the base of the ceramic shell helps lock the pot onto a stove burner. The large, round, easy grip handle makes transport easier and help prevent injury.
