We call this multi-mobile computing. However, the tremendous device, hardware, and software heterogeneity of mobile systems makes this difficult in practice. We present M2, a system for multi-mobile computing across heterogeneous mobile systems that enable new ways of sharing and combining multiple devices. M2 leverages higher-level device abstractions and encoding and decoding hardware in mobile systems to define a client-server device stack that shares devices seamlessly across heterogeneous systems. M2 introduces device transformation, a new technique to mix and match heterogeneous input and output device data including rich media content.
