System for anonymous communication via interactive surface

摘要

A system for anonymous communication between a user and a software application is provided, via interaction of an optical imaging device with an interactive surface to generate interaction data. The device has a unique identity which is associated with the user's identity. The interaction data includes data on the application and device identities. The system has a computer system which receives the interaction data generated by the optical imaging device, identifies the application and the device from the identity data included in the received interaction data, translates the identified application and device identities into an alias identity, sends the alias identity and interaction data to the identified application, receives information from the identified application addressed to the alias identity, and forwards the information from the application to the user via the alias identity.
