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.
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.
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:
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.
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.
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.
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...
John's goal is to find out when trash pickup will be rescheduled. He knows that he can call the township, but he is unsure of what department. He prefers to find the information online.
|ACTION||Find township website||Navigate website||Vist contact page||Complete contact form|
|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|
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.
I am using a card layout to categorize the signs. The user can choose a category and browse the signs in the selected section.
An unmoderated usability study was conducted among 5 participants between 30 and 60 minutes. The study identified several areas of improvement for the design.
This design has mobile, tablet, and desktop versions for the primary pages of the application. By using a card layout, categories are easy to browse and enable users to pick the most popular sets of words to study. The design shows several examples of the 3D sign language hand that will be used in conjunction with three.js to animate the hand with WebGL.
