Refer to GR2 for an explanation of what each screen is for. Refer to the end of this document for a summary of design choices from GR2 incorporated into this prototype.
These photos are of Version 2 of our prototype.
Timeline
Two elements of the UI: a chronological list of journal entries, with the "new entry" button always positioned as the most recent entry, and a map that automatically re-sizes and moves to include all posts currently visible in the entry list. A prominent arrow is loosely fit to the entry points on the map to indicate a rough direction of travel. The arrow is animated as the user scrolls the entry list. Entries in the list accept right clicks (click & hold) to share, edit, or delete the entry.

- One user recommended that we toggle the share/edit/delete buttons by tapping on the screen. After they disappear, the user can tap once on the screen to get them back, and again to make them disappear. This seemed more useful than having them appear when the user scrolls, since the user may want to view the entire post cleanly while they are scrolling.
Prototype Iteration
Testing Version 1
Our first prototype was the Timeline screen of the second design mixed with the View/Edit screen of the first design. After the first round of testing, we made a few big changes to improve the visibility of some features and to improve the learnability of our UI:
...
- We added a set of buttons at the bottom of the screen (share/edit/delete) to allow users to interact with the post they are looking at. So as not to clutter the view screen, we decided to make these buttons disappear after a few seconds. They would reappear for a few seconds when the user scrolls then disappear again. We decided to make them temporary because if the user wanted to perform any of those tasks, they likely came to the view screen with that task in mind, so would press the button for that task right when they enter the view screen.
Testing Version 2
After testing with the second prototype, we decided to make a few more changes to our UI:
