As a personal project, I did all of the research, design and testing for this project on my own.

15-20% of the world's population has a form of dyslexia.

The world has roughly 7.8 billion people living on it, which means anywhere from 1 to 1.5 billion people have dyslexia (Source).

Long emails are especially difficult.

Reading and writing long blocks of text in (often boring) emails is painful for anyone, but it's especially hard for people with dyslexia. However, Gmail is one of those places where you will frequently read and write long blocks of text, and often such text is full of important information.

I spoke directly to people with dyslexia.

To identify the specific pain points of this group and find solutions, I interviewed and surveyed people with dyslexia who use Gmail. Here are some of the questions I asked:​

- As someone with dyslexia, what are some of the difficulties you face reading emails on Gmail?
​- Do you ever experience difficulty typing out email responses on Gmail? If so, please explain.

I identified 2 places to improve Gmail's accessibility.

These are the primary places on Gmail's mobile/web experience that could be made more accessible for people with dyslexia:

1. Long and condensed text blocks.

Blocks of text with a small text size and short line height are more difficult for people with dyslexia, especially if the text is very long. As one of my interviewees said, they tend to re-read emails over and over again before interpreting all of the words correctly, so this can be a very tedious process.

The email sender is responsible for their formatting. However, Gmail could make the reading process easier nonetheless.

2. Stuck on a blank email draft.

Many emails require a complex or wordy reply. For people with dyslexia, this can be a challenge. As noted above, one of my interviewees said that they spend a long time staring at a blank draft. Gmail currently has Smart Compose, where suggestions will appear as you write, but this doesn't help with a blank slate.

Here's how to make Gmail more accessible.

After researching some of the best practices for UI/UX design for people with dyslexia, I designed some solutions.

Smart reading in smaller chunks.

I designed a feature called Easy Reader that allows the user to read long, plain text with a larger font and higher line height.

If an email is detected to be especially long, then the app would prompt you to try Easy Reader to raise awareness of the feature (testing would be needed to determine what is "especially long", but I would try 500 characters or more). The text is then broken up into shorter, more manageable chunks that the user can navigate through using the buttons at the bottom.

An idea to break up the text chunks in the implementation would be to create a new chunk when there is a new line, a sentence ends, or a character limit is reached, in which case a "..." would be added before the chunk ends; whichever of the three comes first.

An option to listen while you read.

With the option to read aloud, the user will see the word that is being read highlighted in blue.

​This way, the user can listen and read at the same time, making it much easier to follow along and comprehend.

This also has an added bonus of benefitting users with difficulty seeing, or who just wish to multitask while listening to an email.

AI-assisted email drafting. 

Based on my research, many people with dyslexia struggle to start writing an email, often staring at a blank email draft.

To solve this, I chose to add a "Generate a Sample Reply with AI" button to the blank email reply screen. When clicked, the AI would read the email sent to you and write an example reply.

This gives the user a baseline from which they can just make edits as needed.

I created this example by giving Chat GPT the original email, and then asking it to create an example reply.

If I were to design this same feature for new email threads, I would simply add an input box where the user can feed the AI a concept before writing.

Live prototype in action.

Would people with dyslexia actually use these?

For each feature (Easy Reader, Read Aloud, and AI-Assisted Email Drafting), I asked five survey respondents who have dyslexia, ​"If Gmail added this feature, would you use it?"
All three scored a 4/5.

All respondents who said they would not use one of the features said that they would use both of the other features.

A more accessible Gmail is a better product for all users.

A more inclusive Gmail experience would help the 15-20% of the population who have some form of dyslexia. With help reading and writing emails, people with dyslexia can get on more even footing with others in the workplace and elsewhere. However, it wouldn't just help those with dyslexia.

All users would benefit from a smoother, smarter reading experience and faster email drafting. With these enhancements, perhaps even more users would switch away from the likes of competition like Microsoft Outlook.

Why stop there?
