The Camera Mic App offers the ability to take pictures using the iPhone or iPod Touch (4th Gen) microphone. The mic from the headset that comes standard with most devices can also be used to operate the camera. Located behind the volume and play buttons of the headset, the circular mic has some tangibility and texture to it allowing a user to "feel" and tap it like a physical button. Similarly, the mic on the iPhone can be touched off the frame of the device, located on the bottom-left side of the home button. Once the mic is touched, the app detects the resulting audio level spike and triggers the camera to take a picture. The sensitivity of the audio levels which activate the camera can be adjusted, allowing users to optimize the app for different environments and scenarios.
