The eTRV product team questioned the wording that should be used in the menu on a new electronic thermostatic radiator valve (eTRV). Two sets of words were proposed. I conducted remote, unmoderated A/B testing with users in Europe to help the team decide which set of temperature terms to use.

Goal: Determine the wording that users comprehend and expect in an eTRV menu

Role: Sole researcher - worked with product management, interaction design, and industrial design to determine the research goals and outcomes

Research Questions:

• Can users successfully complete tasks within the thermostatic radiator valve (TRV) menu?

• Which of 2 sets of temperature terms did users expect to see in an eTRV menu when creating a schedule?

Method:

• Planned and analyzed unmoderated A/B usability sessions through usertesting.com using a digital, clickable prototype of the eTRV

• Designed study tasks and questions that gain users expectations for temperature names

• Triangulate: observe users complete the task, ask them what they expect temperatures to be called, have users choose their preferred set of temperature words

Insights: Name of the 3 temperatures users expected and understood to be used in scheduling

Impact: The team could use names that users expect and understand to lessen a hard task on an eTRV.
