Sleep Wearable

Tatch Health is a health technology startup tackling accessible sleep diagnostics. As their sole UX Design intern, I conducted two rounds of user tests, identified usability issues in their product, suggested solutions, and designed future product materials and packaging.

OVERVIEW

Tatch Health has designed an at-home smart patch for sleep metrics such as oxygen level, heart rate, and snore.

As the UX designer, my goal was to identify design flaws in the Tatch sleep test and improve the user experience of their product while maintaining their brand identity.

RESEARCH & MARKET ANALYSIS

Existing consumer health products appeal to users based on convenience, price, and need.

To start, I researched existing products related to sleep testing and sleep metrics. I looked at a mix of sleep tests and sleep trackers in the form of physical products, apps, and the combination of both, like Tatch.

I tested the patch and app at home to familiarize myself with the product experience.

The most glaring issue concerned a lack of information—when users first opened the product package they had little instruction on how to begin with the test. I created a one-page “quick start guide” to succinctly explain to individuals what the product is and how to get started.

USABILITY TESTING

Usability tests with open-ended questions helped me hone in on how users felt about sleep in relation to the sleep test.

I came up with a condensed, easy-to-read test plan to present to the rest of the team. I then wrote out a user test document with questions such as the following:

- Before taking this test, how interested were you in understanding if you are at risk for sleep apnea? How likely were you to search for information or ask your doctor about sleep apnea? How has that changed since taking this test?

- Tell us about your experience applying the patches. Did anything go wrong? How well did you understand all of the instructions? How could this experience be improved?

I identified 29 design problems with the screens and patch in test one, and 25 design problems in test two.

When the tests were returned, I transcribed the voice recordings and performed a heuristic analysis of the results. I made sure to present the design problems and solutions in a way that the rest of the team, who were non-designers, would understand. I identified 29 design problems with the screens and patches in test one, and 25 design problems in test two.

USER INSIGHTS & DESIGN SOLUTIONS

Users felt like the product lacked data transparency and they wanted to know more about their test.

A particularly salient issue during the user tests was a lack of explanatory information. Users were intimidated by their unfamiliarity with the sleep test and sleep apnea. To remedy this, I focused on providing more information throughout the entire experience for the next iteration of changes.

After discussing with the CEO and selecting which design changes we wanted to make, I adjusted the prototype screens to reflect the changes. I translated each change into an agile task with acceptance criteria and assigned them to the developers on Jira.

UPDATING PRODUCT MATERIALS

They also wanted a sleep report to continue being connected in the process.

The user tests revealed that people were interested in a sleep report, regardless of whether or not they were at risk or had sleep apnea or other disorders. I designed a template for this report to provide users with information about their sleep.

Packaging was a significant part of their product experience, and it needed improvement.

The user tests also revealed information about packaging. Users value good packaging as part of their product experience. Since it’ s important that the product is not damaged in the mail, I designed a product box and an outer shipping box. I wanted both to reflect the Tatch brand, with the inner product box having a sleek and professional look.
