Jargon

Overview

The Problem

Many tradespeople, especially newcomers and multilingual workers, face language barriers that make it difficult to understand and confidently use trade-specific terminology on job sites. These communication gaps can lead to lowered confidence and increased safety risks in high-pressure environments. They can also make it harder to fully grasp workplace guidelines, certification materials, and industry requirements.

Our Solution

Jargon is designed for tradespeople who want to build confidence with trade-specific terminology and ensure better safety on the job. It delivers short, interactive lessons, flashcards, and quizzes, with AI-powered support that lets users upload their own documents or manuals to generate personalized learning content, making it easier to strengthen vocabulary and communicate clearly and safely at work.

Research

Target Audience

Jargon is designed for immigrants in the trades, who make up 22.9% of the construction workforce, with 15–20% in specialized roles like plumbing and electrical. Language barriers are linked to 25% of workplace accidents, and newcomers face a 1.5× higher risk of injury on job sites in comparison to native English speakers.

To better understand our target audience and their challenges and needs I conducted some research before jumping into the design process.

User Survey

I conducted a user survey to better understand the real challenges tradespeople face with language, safety communication, and on-the-job learning. The goal was to validate assumptions, identify key pain points, and ensure the solution is grounded in actual user needs rather than assumptions.

Key Takeaways

Language barriers contribute to 25% of workplace accidents.
Newcomers face a 1.5× higher injury risk.
75% struggle to ask questions or clarify instructions.
Safety terms and workplace documents are hard to understand.
Users prefer practical tasks, short quizzes, and mobile learning.

User Personas

Research revealed two main groups: workers already in the trades and newcomers preparing to enter. Their needs overlap but differ in context, so I created two personas to help define solutions for both on-the-job communication and certification prep.

Action Points

Focus on safety and job-site vocabulary.
Design short, mobile-first lessons.
Use practical, task-based assessments.
Allow skill-specific practice.
Simplify manuals and training materials through AI support.

Design Process

User Flow

My team and I created a user flow to map out how users would move through the app. This helped us identify key touchpoints, reduce friction, and ensure the experience feels simple and intuitive. By visualizing the journey early, we were able to design a smoother, more user-centered experience.

Low-Fidelity Wireframes

Low-fidelity wireframes explored the layout and flow of Jargon, designed to help tradespeople learn and practice terminology in an engaging, game-like way. Rocky, our avatar, guided design decisions to ensure the experience is fun, motivating, and easy to navigate.

Style Guide

The logo combines a text bubble and a mechanical wheel, reflecting Jargon's focus on learning trade-specific language in a hands-on, practical way.

We chose a single, easily readable wordmark paired with industrial-inspired yet playful colors to balance clarity with a fun, approachable feel for users.

Revisions

I conducted multiple design revisions to refine Jargon's usability and engagement. Iterating through several versions and testing with users helped us identify pain points, improve clarity, and ensure the app meets learners' needs effectively.

AI Upload Feature Revision

We streamlined the AI Upload feature flow to make navigation quicker and more intuitive. By shortening steps, users can complete tasks with less friction, stay more engaged, and focus on learning rather than figuring out the process.

Community Revision

Originally planned as a community forum, feedback showed users wanted social interaction. We shifted to leaderboards to keep motivation high while staying true to Jargon's gamified learning focus.

Leaderboards drive motivation, while users can add friends, view profiles, and access AI-personalized lessons. Optional social links let connections extend beyond the app.
