Ownership

UX vision and interaction model

End-to-end experience definition and UI direction

Product trade-offs and implementation alignment

Engineering feasibility and constraints

Responsibilities

Led the core capture and scanning experience

Defined AI-assisted and bulk-scan interaction patterns

Drove UX strategy across key features

Worked with PM and Eng to balance usability and performance

Context & Problem

Adobe Scan is used by over 100M users to capture documents in real-world, often imperfect conditions.

As user needs evolved, the scanning flow became slower and more fragmented.

Mobile Usability

Primary actions were placed in the top bar, making one-handed use slower and less comfortable during capture and review. This added friction to frequent, time-sensitive actions.

Multi-page Scanning

The flow wasn’t optimized for multi-page scanning, despite growing demand.

Over 30% of users scanned three or more pages, yet the experience remained tuned for single-page use.

Fragmented Editing

Editing a scanned PDF required switching to Acrobat and returning to Scan.

This broke the flow and introduced unnecessary friction during common post-scan tasks.

Insights

Speed Is Shaped by Interaction

Action placement directly impacts speed, comfort, and confidence on mobile.

Scanning Isn’t Just One Page

Scanning has evolved into multi-page tasks, not single captures.

Editing Is Part of the Flow

Breaking the flow to edit elsewhere disrupts completion and momentum.

Design Principles

Proximity Over Reach

Place primary actions close to where attention and hands already are.

Continuity Builds Momentum

Treat scanning as a continuous experience rather than a series of discrete steps.

Focus PreservesFlow

Preserve user focus by minimizing unnecessary shifts in tools or mental state.

These principles guided how we restructured the capture and scanning experience.

From Principles to Decisions 

Each principle informed concrete design decisions across the scanning experience.

Focus Preserves Flow

By bringing text editing directly into the scanning flow, users could review and edit documents without breaking context—preserving focus and increasing completion across post-scan tasks.

Reflection

Adobe Scan was a strong example of what’s possible when design, product, and engineering operate as a true team. Working closely across disciplines allowed us to move quickly, stay grounded in real user needs, and ship meaningful improvements at scale.

Given more time, I’d continue exploring:

  • Proactive AI suggestions that anticipate user intent
  • Automated organization driven by document content
  • Adaptive UI for challenging capture conditions

These represent natural next steps toward a more intelligent, context-aware scanning experience.
