Document Summary

Today: metrics, a case study about accessible design. Betsy, who has arthritis, was baking and the conventional vegetable peeler was hurting her hand. Wanted a solution to be able to use the peeler. Sam, her husband, saw the market satisfies our objectives the most? opportunity. Relationship of units may not be linear so be careful! Durability (destroying prototype each time you use it, must be built in order to test which can be a challenge if coming up with design still) Comfort (clients range of motion, can compare to other products, get more customer feedback) Low cost (relative measure to other produ(cid:272)ts, you (cid:373)ay(cid:271)e do(cid:374)"t k(cid:374)ow how much it will cost or what materials you will use) Make sure you are measuring as directly as possible.

Based that design for their prototype design.
