We want to improve the experience of Facebook's Free & For Sale groups.
We want users to rely less on direct communication because the system can handle a lot of it automatically, i.e. the availability of an item.
We used React, Redux and Firebase to build this single-page web application prototype that supports
- Register
- Login
- Search
- Reserve an item
- Post an item
- View your items that are reserved by other users
- View other people's items that you reserve
- Cancel the reservation by other users
- Cancel the reservation by you
We applied many HCI principles to make our prototype easier to understand and use, including but not limited to
- contract
- error prevention
- grouping by proximity and similarity
- recognition instead of recall
