EmoFlowers

This Use Case enables users to create a virtual plant on a planet by performing facail expressions (as game input) and
to cooperate with the other players of the planet. The overall game design is composed of two modules: creation and
co-creation.

The players starts with the creation module by activating the emotion artefact and selecting one out of three seeds (joy/sadness/anger). Afterwards the player determines on which planet to plant his/her seed. When the seed is planted the actual growth phase of the plant begins by triggering Mini-Games that additionally serves as a tutorial to get accustomed to the new input method. Within the Mini-Game players have to react on environmental events, like sunshine for joy, rain for sadness and wind for anger, by performing the required emotional expressions (joy/sadness/anger).

In the next step the player can customize their plants. Branches and items can be attached to the plant. The items available are depending on the level of the plant. These items have an impact on the visual appearance and on the attributes of the plant (presence of joy/sadness/anger). These attributes grant a bonus on certain environmental events. During these events (Mini-Games) players have to reproduce a certain displayed facial expressions to gain growth points that are necessary to attach branches and items. If the required facial expression is not reproduced successfully than the plant will start to shrink.
If the flower has a dominant presence of joy the impact of the sunshine event will result in more growth points gained by reacting better to the environmental events.

In the co-creation module, not only one but multiple players play the game and have to work together to protect their planet and attack other ones. The main difference between creation and co-cCreation is that the existing plants of the player are placed on a new macro level, the world (planet), which represents a community.

In the co-creation module the players are enabled to get in contact with other players via a chat and a group pin board.
Each community has its own pin board, where the player of a community can leave comments, messages and notes. Only the community members can read and post on the pin board, which should also help to make decisions. The player have
the possibility to compare themselves with other players through the provided high score lists.

New are combo points, which can be collected by protecting the planet against outer-space weather events (attacks of other planets) by performing the required facial expression (joy/sadness/anger) or successfully attacking other planets.
These points, shown as a progress bar, are necessary to be able to attack other planets (collect bombs).
