In this Covid-19 pandemic situation, more than 57 million college students are living in shared apartments or college dormitories. 
In a shared apartment, people not only worry about safety problems but also need high-efficiency service provided by apartments.
As some universities resume the fall semester, more and more college student apartments have experienced serious virus transmission incidents.

Check out our vision movie! The insights from our research indicate that we need to establish a platform between residents and apartment service providers, so we created an app that would help them do exactly that.

COSAFE, our apartment service, is sustained by the active participation of a diverse group of stakeholders. At the heart of our operation are our residents, who are our core stakeholders. Their experience, feedback, and satisfaction are crucial to our service's success and continuous improvement. Direct stakeholders such as office staff, maintenance workers, and administration managers. The indirect stakeholders include property owners, government and regulatory authorities.

Reflecting on this project, the collaboration with my three designer colleagues was instrumental in successfully conceiving and realizing our community security app. Our collective efforts in research led to a multitude of insights, opening up a vast array of design opportunities. The challenge was to design a cohesive system that would serve both users and administrators, and I am proud to say that we have achieved this balance.

Recognizing the expansion of our target audience, we dove even deeper into our research to ensure the robustness and versatility of our design. To further enhance user engagement, we integrated an incentive mechanism into the app, encouraging active participation. We envision partnering with local stores as reward providers, thus creating a synergy that not only bolsters community security but also rejuvenates the local economy. The experience of co-creation in this project has been highly enriching and rewarding.
