Your requirement for water quality？
Take water from home
Which way you prefer to get water？
Through the questionnaire survey of the target users, sort out the pie chart up there. From the graphics we can see that target users tend to play basketball with about 500ml of water, when the bottle is empty, they prefer to buy some bottled water from the small store nearby, meanwhile they have no regular drinking habits.
Field investigation on campus, trying to obtain the users’ characteristics and pain points. As it shows in pictures, discarded bottles and some personal stuff are placed on the bottom line edge and site perimeter randomly. Moreover, I conduct some survey on users’ habits, court map and competitors close-by.

1 Interview
2 Second interviewee Senior class height 5’10
First interviewee Senior class height 5’11
Do you take some waters to the court regularly?
Main Question No.
Yeah，I got 2 bottle, each of them 500ml.
How’s your frequency of baketball? And how long each time? hmm...twice a week, 3 to 4 hours each time.
3 times a week, 1～2 hours each time.
Did you have strong desire for water immediately after exercise? I found 2 man playing basketball in our campus. With their permission, I conducted a interview, and then recorded the answers. After summary, I sorted out the basically same conclusion and verified previous conclusion from questionnaire.
Usually I drink in 5～6mins.
Yeah,extremely thirsty and drink immediately.
Q:Would you prefer to use the water device instead of go to small store (if the device exist)? I dont think so,it is unsanitary for many people to use.
No...worry about poor quality and still don’t know how to use it.
