 We designed a mobile application that would help elder mall walkers to find a community meeting place. We created a persona, Bill, who wants to have companions while mall walking but has hard time keeping up with people with different paces and schedules. Mall-E allows Bill to join or create groups so that he can walk or eat together and make new friends at the mall.
