Big Phone, Little Hands

on YouTube ↗11m

" summary

Phones double in size over 11 years while thumb reach stays ~70 mm for men and ~10% less for women so carers often must use one hand while holding a resident, and 80% of Australian aged care workers are female. Implemented a layout that puts the four primary actions in the bottom usable quarter, duplicated back button at bottom as well as top, stores a dominant-hand setting and supports shake-to-swap hand to flip the UI. Prototype exists and is under user testing and code/PDF live on the blog.
