sigInterface: a personalized interface for intelligent services.

We present sigInterface, a personalized interface, which provides intelligent services based on user interests across smart devices (i.e., smartphones, smart TVs, or smart cars). sigInterface understands user interests from the usage data inside a smart device. It enables the device or connected devices to provide intelligent services. Note that sigInterface works in a privacy-protecting manner without sending out usage data to the service provider's server. We implement an intelligent service using sigInterface to confirm its feasibility.
