[WEB SITE] Johns Hopkins taps Apple Watch, ResearchKit for upcoming epilepsy study with eye on seizure prediction

Seeking deeper insight into epileptic seizures and their effect on the human body, Johns Hopkins’ ResearchKit study will collect heart rate sensor and accelerometer data from Watch, gyroscope data from iPhone and dynamic user feedback to track a variety of biometric measurements during a seizure episode, according to a source familiar with the project. The iPhone and Watch apps, now in beta testing, are slated to go live on Sept. 18.While sensor readings are automated, like many current iPhone-based ResearchKit initiatives, other metrics are not so easily ascertained. Activating the test process and measuring lucidity, for example, require some form of direct user interaction, a steep demand considering the extremely stressful nature of a seizure event. To help participants complete individual sessions they are given physical cues to answer contextual onscreen survey questions via Watch’s Taptic Engine. Alternatively, a caregiver might be able to initiate the testing process if present, the person said.
