Certain aspects of a method and system for controlling a user interface of a device using human breath may include a device having an embedded micro-electro-mechanical system (MEMS) sensing and processing module. The MEMS sensing and processing module may detect movement caused by expulsion of human breath by a user. In response to the detection of movement caused by expulsion of human breath, one or more control signals may be generated. The generated control signals may control the user interface of the device and may enable navigation and/or selection of components in the user interface.
