Contribution

Designed and prototyped Paper, a lightweight note-taking experience focused on improving pen adoption and engagement, while exploring AI-powered voice and search capabilities to inform future pen-centric experiences across Lenovo tablets and alternate form factor devices.

Opportunity

Despite years of investment in pen hardware, pen adoption remains limited on PCs

Pen Adoption Challenges

Often perceived as a niche tool
Most pen-dedicated apps feel tablet-oriented, heavy, cluttered, and built for power users, packed with features designed for artists or students with complex workflows.

Pen - OSK switching is not fluid and natural
Switching to the OSK and trackpad becomes clunky the moment the pen is in hand. Without fluid transitions, the pen feels limited, useful only in certain moments

Why now? | The Opportunity

New form factors make pen interactions more practical and visible, while AI PCs enable multimodal interaction, assistance and contextual understanding.

Alternate form factors with input planes
Dual‑screen and foldable laptops create dedicated space for quick capture, markup, and note‑taking, naturally encouraging pen use and expanding where and how the pen can be used.

Emerging Multimodal AI PCs
Emerging AI PCs create opportunities for multimodal interactions with voice, camera, etc. along with contextual understanding and assistance that enhnace traditional pen experiences.

A Pen becomes far more than a niche input when it moves seamlessly across contexts and input methods, evolving into a natural, versatile tool that supports a broader range of tasks

UX Strategy

North Star Strategy for Pen UX

Expand Pen Value with Capture & Act |
Systemwide capture and action workflows make the pen useful across contexts, not just within a single app.

Future Opportunity

Differentiate with Pen + Voice |
Pairing pen and voice creates a multimodal, complementary input system that enables faster and more natural workflows.

Anchor Pen Adoption with Everyday Notes |
A lightweight note-taking experience gives users an immediate, everyday reason to pick up the pen through quick capture and thinking.

For this project, I focused on the first two pillars: everyday note-taking as the anchor experience and exploring Pen + Voice as the primary differentiator.

Everyday Note-taking

What the experience needs to enable?

Snapshot of the brainstorming process

A lightweight set of foundational capabilities established a complete note-taking experience, allowing exploration to focus on AI concepts that most directly supported pen adoption and multimodal interaction.

Foundational Capabilities

Introducing the "Paper" App

Paper is a lightweight, low-friction note‑taking app designed to let users create, capture and edit content instantly as well as access, search and organize them easily.

Core Use Cases
- Capture ideas and reflections instantly
- Maintain a quick, handy journal or a to-do list
- Mark up documents/ create doodles or quick sketches with a few focused tools

Paper is not a replacement for full-featured sketching programs like Procreate, or whiteboarding apps like Miro

Beyond the foundations

Beyond delivering a lightweight note-taking experience, Paper served as a platform for exploring how AI could enhance pen workflows.

AI opportunity space: Concepts explored

#1. Ink and Talk
Using voice to add or edit text

Create

#2. Smart Finder
AI powered search

Find

#3. Smart Select
Context aware options

Assist

Future Opportunity

Ink and Talk, and Smart Finder were selected as the initial focus areas because they form the foundation of the note-taking experience and align most closely with the Pen UX strategy.

#1 Ink and Talk : Deep Dive

  1. Input switching Journey / Pain Points

Entering text remains a keyboard-dependent workflow, even when users are actively working
with a pen.

Design Q: How might voice complement the pen to create a more fluid note-taking experience?
  1. What is Ink and Talk?

  1. Voice and Pen Principle

Pen
- Placement
- Control
- Navigation
- Selection

Pen ≈ Trackpad / mouse
Voice ≈ OSK

Voice
- Text entry / Dictation
- Assistive commands

  1. Interaction Journey for Ink and Talk

Trigger

Pen button
- Long press to activate text tool and listening
- Double press for AI assist

Control

Pen Tip
- Placement of Textbox on the canvas
- Pen to double and select text

Feedback

Color, Icons and Gradient
- Icon above the textbox
- Change in textbox outline/stroke

  • Pen and voice as an alternative to trackpad and keyboard

  • Easily switch between “Draw” and “Dictation” mode

#2 Smart Finder : Deep Dive

  1. Key Insights and Pain Points + Design Principles

1

Users often remember Context

Users often remember a conversation, or where the information is located, rather than the exact words written in their notes.

Traditional search requires users to know what they're searching for and often relies on exact keywords or close matches.

2

Search Should be Conversational

People naturally think in complete thoughts and questions.

Users have to often translate their thoughts into keywords.

3

Users Want Answers, Not Results

Users are trying to find information, not browse search results.

Users have to Scan results in a list, detached from context, open a result, navigate within the note and then locate the relevant content

Design Principles
  • Preserve spatial memory and context

  • Support intent-based search

  • Allow users to search the way they naturally think.

  • Bring users directly to the information they need.

  1. Ideal User Flow

  1. What is Smart Finder?

Smart Finder shifts search from a keyword-and-results model to an intent-and-navigation model, helping users find information the way they naturally remember it

Natural language search that understands contextual queries such as "Where are my notes from Alice's interview?"

Voice-powered search that enables conversational queries instead of keyword construction.

Navigate directly to the relevant area and the result is highlighted within the canvas, in context.

Highlight results

Carousel navigation

Natural language + voice

  1. Design Flow: Smart Finder

Within in a File
Across Folders
  1. Prototype Video Demo: Smart Finder

Search
Typed and handwritten notes, simple drawings
  • Enables the ability to use natural language querying both within individual files and across multiple files

  • It also parses the content for semantic understanding, effectively allowing the user to locate different types of content that don’t directly match the wording of their initial query.

  • Explored cloud vs. local AI processing models

Conclusion

What is Paper unlocking? What's next?

1 | Focus Area
Natural input
Exploring pen and voice as a fluid, natural alternative to keyboard and mouse across the device.
2 | Focus Area
Smart Select
Developing contextual selection as an independent concept beyond Paper across the device.
3 | Process
Collaborative prototyping
Expanding the sandbox model so teams can prototype different ideas in parallel and bring them together in one experience.
