WebCall - A Rich Context Mobile Research Framework.

The ever-increasing capability of mobile devices enables many mobile services far beyond a traditional voice call. In this paper, we present WebCall, a research framework on how to share and utilize the rich contextual information about users, such as phonebook, indoor and outdoor location, and calendar. WebCall also demonstrates a few services (e.g. human powered questions and answers) that can be built on top of user context. Third-party services can be integrated with WebCall through a simple API and potentially benefit from context filtering. An invitation mechanism is introduced to enable boot-strapping user base. Privacy concern is addressed by giving full control to users on how to share their information.
