Thesis Question

How might we increase representation of ASL in messaging platforms?

So what is existing out there that’s in ASL? 

Out of the entire iOS App Store, there were only 2 viable products that communicate ASL. The feedback were as follows: limited options, laddy, too yellow, really questioning about the celebrity prescence there.

So for my proposed solution, I designed Sign’o and had it launch on the App Store. It’s targeted towards deaf young adults whose native language is ASL and its dialects and whom primarily uses iMessage as main tool for communication.


Can it survive the roast? especially when you’re a hearing designer?

Some reddit research

This idea was validated via interviews as well as deaf subreddit groups (why Reddit? cuz people are more honest and direct when they’re anonymous)

Aside from Reddit, I did spoke with a few deaf individuals to attempt to validate the idea. There was definitely interest to see how it would turn out!

Design & Iteration

Bringing it to life from sketch

1) It started off with a video of a sign (in this case, its “No”). Then, after identifying important frames, I traced them out on Illustrator.

2) The tracings are then imported into After Effects for animation and video export. Once exported, the video is then broken up into frames in Photoshop to create GIFs.


Series of initial design drafts

Sign exploration ranging from “No,” “Wow!” and “Whatsup?”

3) Here’s the overall set for the initial design.

Super technical looking with zero personality

After receiving feedback from peers, faculty, and the Deaf, I started reviewing all of them and taking account the fact that this is designed and catered for the deaf. The one key feedback I got was that the stickers looked too realistic to be friendly, cartoonish, and usable as stickers.

Final Design

A slim, bouncy, rubbery cartoon

So... a few sketches and tweaks later, I landed on this final design.

Final design

It’s also important to highlight that color, texts and complicated designs were forfeited for the sake of higher frames per second (fps) that gives the sticker its fluid motion. Restrictions were set by Apple.

The final design, as a master, was used to design other signs and letters.

And repeated the whole cycle again...

And after a successful upload onto Xcode and a whole lot of blind debugging...

It’s live on the App Store!
