While the tool we made is accessible, testing them with users gave us further insight into how we can make our prototype better. Due to time constraints, however, we had to stop prototyping at this stage. We would like to make a note of additional points and improvements that we collected through the project. These include:

• Allow users to upload their own datasets.

• Enable users to tab through data points more efficiently.

• Build the app to be generalizable to data beyond stock prices.

• Deploy this proof of concept as a fully functioning product on the app store.

And in spite all of all the remaining work to be done, the last few testing sessions gave us confidence that our proof of concept is on the right track!

We are proud to say that we have achieved our goal of helping users with visual impairments gather the gist of a line graph. The implications are far reaching. Bloomberg can pioneer this technology among clients, enabling those with with visual impairments to get the information they need. The technology can also be used by sighted clients who seek an alternative way to consume data. As one sighted participant in our study said, it would be cool to be able to listen to stock chart data while driving. And beyond that, Bloomberg's efforts in this space would positively benefit the potentially 39 million people worldwide who have visual impairments. The technology would empower such individuals to pursue careers in finance and other STEM fields that they would not ordinarily pursue.

To help you understand the real and significant impact of what Bloomberg has accomplished by supporting the development of this technology, we’d like to share the closing thoughts of one of our blind participants.
