Intro

Intro

Over 21% of U.S. households speak a language other than English, yet many bilingual parents struggle to maintain their child’s mother tongue. Ages 0–5 are critical for language development, making early exposure essential (Kuhl, 2010). Toys to Stories helps by turning everyday toys into interactive companions, making bilingual storytelling easy and playful for busy parents.

Parents aim to nurture bilingualism by actively integrating their heritage language into daily life, hoping to pass down culture, identity, and connection to family roots.

Pain Points that Parents Struggle With:

😵‍💫

Hard to Maintain Mother Tongue

In an English-dominant environment, parents find it hard to maintain consistent use of their heritage language.

😮‍💨

Too Tired to Be Creative

After a long day, they often lack the time or energy to create engaging, spontaneous stories for their children.

Research Insights

Lack of Time, Engagement & Ease

Lack of Time

Parents are mentally and physically drained after work and household responsibilities, leaving little bandwidth to come up with a story.

"After finishing work, cooking dinner, and doing housework, I just don’t have the energy or mental bandwidth to come up with stories." -P1

🧸

Lack of Engagement

Children often found existing bilingual resources boring or disconnected from their interests, making it difficult to maintain their attention.

"We’re trying to raise our daughter bilingual, but she only speaks English...I even had to hide English version of Dragons Love Tacos so she’d choose the Spanish version just to encourage her to engage with Spanish." -P2

✍🏻

Lack of Ease

Some parents already use ChatGPT for making stories, but without prompting skills, results were inconsistent and frustrating to repeat.

"I already use ChatGPT to tell my son stories based on his favorite toys, but it’s such a redundant process...I have to start from scratch every time." -P3

Opportunity

Opportunity

Opportunity

Language learning is more effective when built on toys children already love.

Children are emotionally attached to their favorite toys. Turning these toys into bilingual stories helps them learn through comfort and play. Storytelling is effective for language learning because it is already part of their daily routine (Fortuna et al., 2014; Grolig et al., 2020).

Designing Prompts for Purposeful Learning & Play

Final Prompt Design

Improved Prompt Accuracy and Output

🎯

More Accurate: Each step stays focused, reducing errors.

Cleaner Context: Keeps inputs clear and avoids mixing stages.

🐛

Easier to Debug: Fix or improve one section without affecting the rest.

Here's the Process

Goal of Prompt

Our First Attempt at Story Generation

🧸

Create imaginative, toy-based stories using uploaded images as inspiration for characters.

📚

Teach language and a life lesson that has a valuable moral or social skill to young children.

Usability Test

Prompt Usability Findings

Focused on:

  • Story quality

  • Emotional tone

  • Usability

  • Desirability


Findings:

  • Story Structure: Needed preview, adjustable length, and word customization

  • Guardrails: Block child-face uploads

  • IP Sensitivity: Avoid references to famous characters like Winnie the Pooh

Potentially Infringed Laws

Staying Legally Safe with AI-Generated Content

I discovered the prompt could potentially violate copyright or trademark laws. To better understand the risks, I interviewed an expert in IP law, who explained that using characters like Winnie the Pooh could create unauthorized derivative works and lead to brand confusion.

Prompt Design Improvements 

Refining the Prompt for Kids, Parents, and AI

Based on the feedbacks, I improved the prompt to generate better-structured stories, designed to simplify language, avoid legal risks, and support language learning. Parents get a preview, and kids learn vocabulary and values through playful stories.

Prompt Structure Overview:

Goal: What the model should do.

🔹

Return Format: What to return and how to structure it.

⚠️

Guardrails: Avoids errors, sets legal and safety boundaries.

🚫

IP Safety: Prevents use of copyrighted or branded content.

🖌️

Storytelling Principles: Guides story flow (Character → Problem → Emotion → Resolution).

📄

Context Dump: Explains the prompt’s purpose and audience.

Prompt Implementation

Prompt Chaining for More Accurate Output

Working with the UX Engineer, the original single prompt worked in GPT playground but didn’t perform well in the app. We split it into four prompts to improve accuracy, handle inputs better, and control the output flow. We later switched to the Gemini 2.0 model due to better cost-effectiveness.

Designing the App That Makes AI Feel Magical

Overview of App

Quick Demo of Prototype

I collaborated with UX engineer to map out a system diagram. This clarified what the prompt needed to extract from the JSON file and at which step of the user flow that data would be used.

To minimize the effort of story creation for busy parents, we structured the app into three simple sections: Onboarding, Preview, and Story Mode and Library.


Onboarding: Helps parents start quickly by guiding through language selection, reading level and toy upload.

Preview: Gives a quick look at the story setup, allowing parents to make small adjustments.

Story Mode: Final output for storytelling with their child.

Library: Stores previously scanned toys and generated stories for easy reuse and quicker access.

Here's the Process

Usability Test

Seeing the Magic Firsthand Through Testing

The team conducted 3 rounds of testing with bilingual parents and their children, observing how they used the app. We focused on engagement, learning value, and where they wanted more control.

During testing, we saw the power of design when the child lit up with joy as she experienced her toy coming to life in the story.

Feedbacks & Iterations 1: Cultural Sensitivity

🌎 Flags Didn’t Feel Inclusive for Multilingual or Diaspora Communities.

Initially, I used flags to reduce cognitive load by providing familiar visual cues, especially for parents scanning quickly or with limited literacy.


Iteration: Replaced flags with native language labels (e.g., “Español”, “中文”) to shift focus from national identity to language itself, and changed "Others" to "More Languages"


Why: This promotes cultural sensitivity, avoids political assumptions, and feels more inclusive for multilingual and diaspora communities.

✅ Benefits of the Change

  1. More Inclusive: Avoids political associations and better reflects global, multilingual communities

  2. Culturally Sensitive: Doesn’t favor one region for widely spoken languages.

  3. Focuses on the language, not the flag.

⚠️ Trade-offs

  1. Less Instant Visual Recognition: Flags are faster to identify, especially for unfamiliar scripts.

  2. Slightly Higher Effort: Some parents may take longer to read native labels.

But with only 5 options, this has little impact

Feedbacks & Iterations 2: Personalized Vocabulary Learning

📚 Parents Loved the ‘Words to Learn’ Section, but Wished They Could Customize.

Iteration: Added the option for parents to swap out vocabulary words during story preview, letting them replace words their child already knows.

Why: This feature gives parents more control, personalizes the learning experience, and supports different developmental stages, especially valuable in bilingual homes.

To get to this, I explored these 2 designs:

Exploration 1: “Re-Choose” Button


✅ Lower effort, supports quicker decisions.

✅ Can use reading level from onboarding to improve accuracy.


⚠️ Less predictable, parents may not trust the output.

Exploration 2: Select Words Directly from the Story


✅ Gives parents full control to choose relevant words.


⚠️ Increases cognitive load, requires reading the entire story first.

Feedbacks & Iterations 3: Enhancing Story Engagement

🧸 Let More Toys Come Together to Make the Stories More Dynamic

Iteration: Expanded story generation to include multiple toy characters for group adventures.


Why: Supports richer storytelling, encourages social behaviors like teamwork, and reflects how children naturally play with multiple toys.

Concerns and Considerations

Concerns in Using AI for Storytelling

🧠

Loss of Cultural and Emotional Nuance

AI-generated stories may miss the depth, humor, and traditions that make heritage storytelling meaningful.

Consideration: Can AI capture dialects and storytelling styles that resonate emotionally across cultures?

🤖

Over-Reliance on AI for Language Learning

While AI can assist, it risks displacing meaningful parent-child interactions if overused.

Consideration: How do we design AI tools to enhance, not replace, human connection?

🎯

Accuracy and Bias in AI-Generated Content

Training data often reflects dominant cultural norms, leading to oversimplified grammar or inaccurate cultural representations.

Consideration: How can we introduce parent oversight and cultural context without overwhelming the user?

Embed data tracking to measure early engagement and learning impact, focusing on:



  • Story completion rate.

  • User retention (Day 1, 7, 30).

  • Number of stories generated / user

📔

Diary Study Testing

Conduct a 2–4 week diary study with bilingual families using the prototype, to gather insights on:

  • Effectiveness on language learning: How often the child interacts with their mother tongue and do they remember the vocabulary.

  • Child Engagement Over Time: Whether initial excitement fades or deepens.

📱

UXUI Refinement

Iterate on story creation flow, visuals, and voice tone based on feedback, to improve usability, engagement, and ensure the experience is intuitive for both children and parents.

Utilizing AI in a Meaningful Way

Not Just Designing Prompts, But Designing Prompt Strategy

The order and structure of prompts affect how the AI answers. Breaking complex prompts, chaining, and few-shot learning improved story flow, vocabulary, and accuracy.

Balancing AI Creativity with User Control to Keep Stories Personal and Easy

Effective AI storytelling balances creative automation with parent input. Too much automation feels impersonal, and too much manual effort creates friction.

When You Design for Kids You Also Design for Parents

Though designed for children, parents guide the experience. The design must address both the parent’s needs and the child’s learning experience, ensuring both find value and ease in the interaction.
