Precedent Research:

In our precedent research we found people are more likely to do something when given the ability to say no. Therefore, the giving portion of this is not mandatory. But we are placing the donation box in a public place which allows there to be a social aspect to the donation box. In motivational apps, they found the ones that were the most successful had a social aspect where people would hold each other accountable and give each other praise. By having the donation box where everyone could see a person putting money into the donation box and seeing the actual impact of putting money into that environment, it would cause people to give more often. 

Additionally we used BJ Fogg’s Model where we change behavior through motivation, ability and triggers. We make it easy for people to do an activity, give them the motivation through the information our display is showing and give them the trigger through the public affirmation. Therefore, people who just bought their coffee could easily give their left over change to the drought stricken community.
