V1.0 Release Notes


The iSensor Lab is pleased to announce its first public release (version 1.0) of the android mobile application; CV19 SelfDefense. The CV19 SelfDefense mobile app is a research project funded by Florida State University Collaborative Collision Seed Grant (CC-045704, 5/11/20 – 8/18/20). Interested users may download this version on an android phone, register an account with the iSensor server, and login to their personal account with a dashboard of features and tools to begin utilizing the services provided that help users to defend themselves during the Coronavirus pandemic. Dashboard features include the following:

  • News Updates: Users will receive an RSS feed of recent postings from the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC) and Department of Health and Human Services (HHS).
  • Test Center Locator: Users can identify nearby test centers based on user’s current geo-location. There are approximately 4,700 test centers across 40 states in the current database. Please contact us at if you have comments.
  • Symptoms Checker: Users can assess development of their own symptoms based on CDC guidelines.
  • Social Distance ‘Nudge’: Adopting Bluetooth technology, users can scan the surrounding areas – via automated or manual scan – to get “nudges” (phone vibration and notification of other nearby devices). This feature also helps users to identify and remember contacts and safe devices of close interactions, and thus create a ‘safe social pod‘ when necessary.
  • Quarantine Monitor: This feature helps users to monitor and keep track of personal whereabouts during a self-quarantine period of 14 days. Multiple home locations – where users feel safe – can be added to assist users’ memory. A summary report will be generated at the end of the quarantine period.
  • Account Profile: Users can change passwords, login and logout of the app from the negation drawer by pulling from the left-hand side of the app.

We hope this tool can help users not only receive up-to-date information from the healthcare authorities, but also defend heir personal health against Coronavirus. Click here for the tutorial. We welcome your feedback.
