For people on-the-go, Voca lets them send text messages by voice, eliminating the need to type.
In phase 2 we implemented user feedback from phase 1 to refine the product. We also introduced features for a new kind of user: the driver.
The target users for Phase 2 were people that want to answer messages while On-the-Go, literally. We focused on truck drivers who are forced to spend long hours on the road, as well as busy professionals who have a long daily commute and want to put that time to better use.
The main challenge going from Phase 1 to Phase 2 was the user flow. Answering texts while driving called for a much simpler flow, one that did not require the user to squint at tiny font to read their incoming messages, or click five buttons before they could reply. In order to solve this problem we created another screen, one that would play incoming messages out loud, with a large button for responding easily.
The play message screen is simple on purpose. This is a screen that most likely will never be used except for driving, so it has a minimum number of options with extra large buttons that are easy to tap without requiring too much attention.
I experimented with other ways to allow the message to be played, but both the dictation screen and message thread had too much information already. Plus, we did not want to ruin the simple user experience for the users that were using the app only for its basic feature (texting by voice).
Other Changes: Motion Sensors
In order to make the contacts screen and dictation screen more appropriate for driving, the screens had to be responsive to when a person is driving. We developed Voca to detect the driving motion, which enlarges texts to make it easier to read while On-the-Go.
Voca's user base is varied, as well as their use of the product features. Some love it for driving, while others ask us to add more features suitable for driving, such as read-back before sending.
Looking back, one thing we could have improved on was to spend more time on the new user at the beginning of Phase 2.
