Comm.unity is a platform that implements a wireless, device-to-device information system that bypasses the need for any centralized servers, coordination, or administration. A key feature of the platform is that it combines knowledge, awareness, and learning of the user's social relationships and integrates this information into the communication protocols and network services. Comm.unity is designed to work on as many devices as possible, and with as many different radios as possible (WiFi, Bluetooth, IR). It is designed as a platform over which many different networked applications could be developed with ease. SnapN�Share and additional applications in development are intended to be used in upcoming field studies to collect information about user behavior and their social interactions, and aid in fine-tuning the platform�s learning capabilities.
