The Nunchi patent portfolio describes foundational technologies of mobile devices, cloud computing and adaptive computing enabling mobile devices to function introspectively, adaptively, and anticipatorily, providing new user experiences, new revenue models and adding value for mobile communications. The technology behind e.Digital’s Nunchi, gathers sensor and user data from enabled mobile devices. Cloud based advanced signal processing is used to combine sensor and user information, interpret surroundings, activities, conditions and the social situation of the user and act on that understanding. The greatest impact of e.Digital’s technology is achieved when all of the layers of local sensor, historic data, group interaction and world information are integrated together to deliver greater levels of social, business, lifestyle, personal safety, and market intelligence functionality.

The Nunchi technology enables applications in the areas of health, wellness, emergency response, personal safety, social and professional networking, user diaries, communication screening and time management. The Nunchi technologies enable enhanced levels of privacy protection by reacting to context changes in a manner providing the best privacy and security for users.

These new technologies apply to smartphones and tablets as they are currently fielded and take advantage of existing communication infrastructures and network systems.
