Trio allows people with essential tremors to do tasks that would otherwise not be possible. Users regain the freedom to type on a computer or smartphone, write a letter, hold a cup of coffee and do many other tasks that require fine motor skills.

To treat essential tremors effectively, users need more than a mass-prescribed medication. They need a personalized solution that targets the source of their tremor. Trio is the first FDA approved, wrist-worn essential tremors therapy device that is calibrated and prescribed specifically to the patient's condition.

The discrete, yet familiar form factor is easy to use and contributes to the success of the Trio therapeutic wearable.

Docking the Trio for charging was a key interaction. Through extensive user studies, we discovered that aligning charging contacts was a challenge for users. Through an empathetic and iterative design approach, we carefully modeled a base that funneled the wristband into the docking position. The addition of magnets guaranteed good contact every time.

Nested cable management allows users to easily travel with Trio anywhere without having to worry about lost cables.
