The study assesses the usability of Obi Gen 3 through quantitative surveys and qualitative interviews across three user groups: providers, caregivers, and patients. Measures include the System Usability Scale (SUS), questions based on the Matching Person \& Technology (MPT) assessment and framework, and a custom Obi Medical Device Needs Assessment (MDNA). Data collection includes pre-trial in-office screening and post-trial surveys gathered remotely using Qualtrics. Optional follow-up interviews gather further feedback. The study aims to verify that the Obi Gen 3 meets its intended use and user needs in real-world environments.
