Here are a few samples of early prototypes that I would share with the design team. They are created mostly in Principle. Most are interactive to convey specific flows or behaviors. In most cases the low to mid fidelity prototypes would focus on a specific aspect of the interaction mechanics of each feature. They are incredibly useful in design reviews and documents to the designers and engineers. along with the typical flow diagram, the prototype gives the team the complete picture of the feature.
This prototype is meant to communicate the mechanics of a new Customize mode in the Player fort. When a purchased item placed in the fort is removed by the player, the item would then be added to the “Saved Item” palette for easy tracking as opposed to sending it back to the original category tab. The Customize mode in Fort Editor also served as the edit mode where the player would rearrange their fort.
The prototype sold the idea and the implemented in-game version did as well.
A few examples of flow boards I share with the teams. The one page design of the feature is typically created in photoshop.
