چکیده (انگلیسی):

To be small and easy to carry, mobile devices cannot be equipped with large and highly capable
input/output devices. In order to overcome these limitations, this study proposes adaptive I/O
switching technique as a general solution for exploiting full features of various external input/output
devices in lieu of tiny input/output devices in a smartphone. Unlike existing physical-layer connection
based solutions or application-layer non-system solutions, we propose a generalized solution at the
mobile platform level. With this generalized solution, whatever activities of a smartphone can be
resolution-adaptively displayed in an external display device. Also, the generalized solution allows us
to use any kinds of external input devices for general mobile applications even if they are not designed
so. Adaptive I/O Switching technique is actually implemented on open source mobile platform and its
effectiveness is demonstrated with several example scenarios.
