Volume adjustment on hinged multi-screen device

A mobile computing device comprising:

• a housing having a first part and a second part, the first part including a first display and a first forward facing camera, and the second part including a second display and a second forward facing camera, wherein the first part and the second part are coupled by a hinge configured to permit the first and second displays to rotate between angular orientations from a face-to-face angular orientation to a back-to-back angular orientation;
• at least one speaker mounted in the housing;
• a sensor mounted in the housing and configured to detected relative angular displacement between the first and second parts of the housing;
• a processor configured to adjust a parameter of audio played back on the at least one speaker based upon the detected relative angular displacement;
• and
• wherein the audio includes a first audio stream and a second audio stream, and the parameter adjusted is a volume balance of the first audio stream associated with a graphical user interface element displayed on the first display and the second audio stream associated with a graphical user interface element displayed on the second display.

A method comprising:

• displaying a first graphical user interface element having an associated first audio stream on a first display included in a first part of a housing of a mobile computing device;
• displaying a second graphical user interface element having an associated second audio stream on a second display included in a second part of the housing, wherein the first part and the second part are coupled by a hinge configured to permit the first and second displays to rotate between angular orientations from a face-to-face angular orientation to a back-to-back angular orientation;
• capturing respective first and second images via a first forward facing camera included in the first part of the housing and a second forward facing camera included in the second part of the housing;
• performing face detection on the first and second images;
• adjusting an audio setting based on a result of the face detection;
• and
• playing the first and second audio streams out of at least one speaker mounted in the housing based on the adjusted audio setting.
