We understand that our clients come to us at various stages of the medical device and Software as a Medical Device (SaMD) design and development process looking for varying levels of guidance. That’s why we develop a unique human factors testing (HF), User Experience (UX) and User Interface (UI) package for each of our clients, customizing our services to meet their specific needs.

Improvita UX-UI Design for medical software

UI / UX Design Research & Testing

We will help you make sure the right decisions are being made early on in your product development process. We do this through usability testing and analysis.

  • UX Testing to evaluate a user’s emotions and attitudes about using any device.
  • UI Testing to evaluate the visual / graphic presentation of a digital device and its intended user.
  • Usability testing to test the ease of use and satisfaction of the user. Using a SUS (system usability scale), we will score your device so you know if it will pass Ease of Use requirements.

We use a variety of research tools and methodologies to uncover unmet needs and to identify user interface issues and opportunities.

  • In-depth interviews
  • Gap analysis to regulatory standards
  • Ethnographic research: The study of people through observation and point of view of the subject.
  • Contextual inquiry
  • User needs identification
  • Focus groups: in person, digital

Usability & Human Factors Testing

To assure the optimization of your device while also meeting FDA testing guidelines, we use a variety of testing processes and methods.

  • Human factors formative (verification) is early stage testing to identify problems.
  • We will set up criteria through risk management activities to identify areas where participants would fail, pass or have a “slip-up” or “close call” while using your product.
  • Instructions for use (IFU) design
  • Human factors summative (validation) is validation testing as mandated by the FDA
  • SaMD / Clinical validation testing (plan and execute)
    • Model training & validation: pattern recognition, neural networks, algorithm, machine learning, artificial intelligence (AI), data mining, problem solving
    • AI and Machine Learning analytical testing (plan and execute)
