Learn Sign Language Case Study for Google UX Certificate

My Role UX Designer, Researcher

This project designs an interactive tool for users to learn American Sign Language through modern technologies

What is the project goal?

Existing tools that teach American Sign Language utilize short videos to demonstrate signs. These videos are not interactive and usually only teach from a single angle. My goal is to create an interactive platform that teaches American Sign Language using 3D hands that offers games, quizzes, and more.

Who is the target audience?

My target audience would be any user who wants to learn ASL, this could be a person who is deaf, a parent wanting to communicate with their baby, or a relative who wants to communicate with a family member. There are many reasons to learn American Sign Language and this would be an excellent tool to get started.

Key Challenges and Constraints

I want to make sure that our application is useable by a wide range of people. The township census data reports a population of 20,000 residents with an average age of 43; approximately 20% of the population is under 18 years old. Based on these statistics, I am identifying the following challenges:

Accessibility

Residents who are disabled should be able to consume the information and features in this application. Any video must have a transcript and/or closed captioning.

Cost and Time

There are several thousand signs used in the American Sign Language system. I must group these signs into categories and offer the most useful first, slowly growing our library over time.

Performance

I will have to ensure that the app is properly optimized since we will be using 3D models rendered with WebGL and three.js. Continuous testing will enable us to develop a responsive application.

Research Study

My research used data on study habits for language learning in addition to a competitor analysis. This data helped me determine what I could do better and motivate users to be consistent with their progress. There were several monetized competitors and only one competitor that used 3D models to translate words into sign language. Let's meet our persona...

Improvement Opportunities Physical displays on township property advertising the website Add a quick links section for residents to quickly get to important pages Provide an interactive component to try to deal with common issues without the need to contact the township John has to wait for a response but would prefer a quicker answer

Design Concepts

My ideation phase focused on ways to provide a learning experience that was fun. I added multiple ways to practice new skills and keeping the learning process fresh and interesting.

Goals of the Design Concepts

  • Use quizzes, exercises and games to keep things interesting.
  • Separate
