Design an app for elderly users to video call their family.
Model answer
Model answerThe key insight is that the user's definition of 'ease' is completely different from typical users. No app icons, no login, no settings. My design: one big button per family member with their photo. Press it, it calls. That's it. For setup, the family member does everything remotely. I'd measure success by call frequency and whether users can make a call independently after one week.
