Principles established to narrow down options.
With Data Science, created a progressive experiment plan to test the hypothesis. First, reverting to the original design before the dip in engagement, then tested incremental changes until the desired result.
Step 1: Revert to original design
Step 2: Move important actions to the right
Step 3: Remove and reorder actions
Step 4: Move voice action outside of input box
Step 5: Visually group actions
Step 6: Apply color to send action
Step 7: Taller container
The effort included both a phased design and testing approach, resulting in recovered metric losses and increased voice message usage by 5.7%.
Additionally, having a taller text input box, support for more text, and bold coloring of the Voice / Send buttons created brand differentiation from competitors, a priority for Google.
