Playbook: Revision Control & Comparison for Interactive Mockups

When designing interactive interfaces and behaviors, interface designers compare and contrast multiple design ideas, often creating and testing many intermediate user interface prototypes before deciding on a final design. However, existing interface prototyping and creation tools do not effectively let designers explore, compare, or keep track of older versions of interface mockups, implicitly making the assumption that the users of these tools will work with one design alternative at a time. To explore how to enable designers to work with multiple designs in a prototyping tool, we created Playbook, a new system oriented towards helping interface designers keep track of, compare, and create interactive mockups. In this paper, we describe Playbook and discuss ways that future prototyping tools can better support the workflow of designers.
