The document summarizes the design process of a group of students creating a wearable tracking device for finding lost friends at music festivals. It describes conducting user research including interviews that identified trends around attending events in large groups and the challenges of losing cell service. The group then defined design challenges around finding lost people without relying on cell phones or internet. They created a mission statement and prototype design for a discreet, standalone Bluetooth tracking device that connects users by name for peace of mind in finding lost friends.

16. QUOTES
Chester: “I like to get lost in the music and enjoy the
moment, but at the back of my mind I’m always keeping tabs
on my friends. It really withdraws from the experience.”
Anisa: "I'm here to have a good time and bond with my
friends. I like to plan a lot in advance, but no matter how
organized my friends are it’s really easy to get lost."

17. Goal:
Find lost friends quickly
and easily

Challenge #2
ACCESS TO INTERNET OR
CELL PHONE SIGNAL

19. Chester: “Yes, it is difficult to find service when everyone’s
phone is trying to look for service too. This drains my battery
a lot, which is why I try to stay away from phone as much as
possible.”
Anisa: “A lot of the big festivals that my friends and I go to
are usually in the middle of nowhere. So finding cell phone
service in those areas is almost impossible.”
QUOTES

20. Goal:
Don’t rely on internet or
cell signal

Challenge #3
CARRYING OBJECTS

22. QUOTES
Chester: "Showing up to an event with a lot of things to carry
makes it difficult to dance and navigate crowds. I'd rather just
go without and ask one of my buddies to carry the important
things for me, like my phone or water."
Anisa: "I try to bring everything I could need with me. I would
hate to be hungry or thirsty and regret not packing
something."

23. Goal:
Small enough to not get
in the way

24. MISSION STATEMENT
Design a wearable tracking device that
is discreet, standalone, and does not
rely on the internet.
