  • Publication number: 20190163154
    Abstract: A device recommendation system includes an environmental monitoring module, a device monitoring module, an abnormality monitoring module and a decision module. The environmental monitoring module receives environmental data obtained by environmental sensors and generates environmental history data accordingly. The device monitoring module retrieves enablement counts from electronic devices and generates enablement history data accordingly.
