Overview
Crafting a gesture-first mobile experience
Project Delta was a complete rethinking of the mobile experience — moving from a button-heavy interface to a fluid, gesture-first interaction model. The goal was to bring the speed and expressiveness of native iOS and Android patterns into a complex, multi-feature product that had historically prioritized desktop.
I led the interaction design work from concept through implementation, spending significant time with the engineering team to understand what was feasible at 60fps, and prototyping extensively in Origami Studio and SwiftUI to validate ideas before any production code was written.
The Challenge
Making complex power available through simple gestures
The core tension was between discoverability and efficiency. Gestures are fast for users who know them, but invisible to those who don't. We solved this by designing a progressive disclosure model: obvious affordances for new users that gradually fade into the background as gestures are learned. The transition felt natural rather than arbitrary, guided by behavioral triggers rather than arbitrary time thresholds.
[Process documentation and imagery to be added — gesture vocabulary documentation, prototypes, side-by-side comparisons, engineering collaboration notes, A/B test results.]
Outcome
Faster, more expressive mobile sessions
Post-launch analytics showed a significant increase in session depth on mobile — users were navigating deeper into the product and completing more tasks per session. Qualitative feedback praised the "speed" and "flow" of the new interaction model. App store ratings improved by half a star within two months of the release.
