Picture This is a game that encourages people to explore their
environment and go places they have not gone before. The game consists
of challenges where the challenger takes a picture at a specific
location and sends it to one or multiple other users, who have
downloaded the app and are currently in the challenger's Google+
circles. Given a hint regarding where the challenge picture was taken,
the challenged user(s) must venture out to find the place and reply
with their own picture, matching the original as closely as
possible. This response can either be approved or declined by the
challenger. If the response is approved, the challenged user wins the
challenge and is rewarded with points; if the response is declined,
the challenged user can try again, until someone wins the
challenge. Each user's points are tracked using Google Games, which
also grants them achievements based on specific actions. They can
access their achievements and the leaderboard form a side tab on the
homepage.
The app has five screens: Login, using Google+; Challenges Home, where
the user can see the challenges they have sent and received; View
Challenge, where the user can view the challenges they have received;
View Response, where the user can see the responses to the challenge
they have issued; Create Challenge, where the user can create a
challenge; and Challenge Map, where the user can view a circle around
the location where the picture was taken. Parse is used to store and
access the data. Material Design is used to make the layout more
appealing and user-friendly. Embedded Google maps are used to display
a radius around the location where the picture was taken. Users get
push notifications when they receive a challenge or a response and
when their responses are accepted or declined.
