Your webcam could soon check your health: study tests video vital signs
NCT ID NCT04820387
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study from Johns Hopkins University is testing whether a video camera can accurately measure vital signs like blood oxygen levels. Researchers will record 94 healthy adults and compare video data with standard medical sensors. If it works, this technology could make telemedicine visits more effective by allowing doctors to check vital signs remotely.
