Strategies and Good Examples of Multiscreen UX

In last blog post, I talked about some basic principles to follow when designing for multi-screens. There is 3Cs Framework (Consistent, Continuous, Complementary) I found extremely helpful when analyzing the strategies of multiscreen design.

However, there are more specific strategies could be discussed which I believe can also fit into the 3Cs Framework. The book Multiscreen UX Design provides 17 strategies of multiscreen UX, and I tried to categorize them into the 3Cs Framework:

  • Consistent

    • Mobile First: Concentrate on the smallest device first, which forces a meaningful structure of information
    • Coherence: Individual features are optimized for device capabilities
    • Fluidity: The display is switched between the screens involved
  • Continuous

    • Device shifting: The display of information or content is shifted to a separate device by the user
    • Synchronization: Information is kept in sync and up-to-date across devices.
