Certain aspects of a method and system for controlling a user interface of a device using human breath may include detecting 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 a device and may enable navigation and/or selection of components in the user interface. The generated one or more control signals may be communicated to the device being controlled via a wired and/or a wireless signal. The expulsion of the human breath may occur in open space and the detection of the movement caused by the expulsion may occur without the use of a channel. The detection of the movement and/or the generation of the control signals may be performed by a MEMS detector or sensor.
