As a UX design intern at Sonova, I worked on several projects to improve the digital experience for hearing aid users. I led a project in which I designed and researched a feature for users to find lost hearing aids through bluetooth connectivity.

Build a feature within the existing Sonova app to help users find their lost hearing instruments (HIs) easily and efficiently.

I made the following assumptions for this project based on previous data about users...

1. User is not cognitively impaired

2. User is mobile

3. User is comfortable using a HI paired smart phone app

4. User wants to find HIs in a way that suits their needs and expectations

Meet Christopher

I created a persona of a typical HI user which includes an older adult who on average is above the age of 65 years. Given their age, they tend to be more forgetful and misplaces their HIs commonly. They have difficulty finding them and need a simple solution to their problem.

A Typical User Journey...

After creating a persona and user journey map based on the assumptions about an HI user, I determined certain technical requirements that would make the project feasible

Technical Requirements

1. Notifications

Should be sent to the user when the last known location of HIs has been different from their current location

2. Map View

Displaying the last known location on an interactive map like Google/Apple maps

3. Proximity Sensor

Have a salient signal displayed visually and haptically when the user is in close proximity to their lost HI

4. Custom Control

Have the ability to locate the left and right HI individually incase only one of them is lost

5. Displays

The following should be displayed in the app UI: HI battery level, disconnection status, last known location

Now for the Visuals!

I created several lo-fidelity iterations of the initial UI through wire-framing different screens and incorporating the technical requirements.

Iteration 1

Iteration 2

Iteration 3

After creating wireframes, I conducted internal validation with the design team and created a high fidelity prototype.

I used this mini brand guide and reference frames to design the new “find my HI” feature. The app did not have an official design system at the time therefore the screens were below were used as a primary reference to create cohesion
