Ascertaining presentation format based on device primary control determination

A computationally-implemented system, comprising:

• means for determining which of a plurality of users detected in proximate vicinity of a computing device has primary control of the computing device, the computing device designed for presenting one or more items and configured to facilitate at least some of the plurality of users to jointly provide input at least in part via a shared input device associated with the computing device;
• means for ascertaining one or more particular formats for formatting the one or more items responsive, at least in part, to said means for determining, including at least:
• means for ascertaining the one or more particular formats by ascertaining that the one or more particular formats are associated with the user detected as having primary control of the computing device, including at least:
• means for ascertaining the one or more particular formats at least partially by ascertaining whether one or more presentation preferences are associated with the user detected as having primary control of the computing device, the one or more presentation preferences being one or more preferences for how the one or more items are to be preferably presented via the computing device, and the one or more presentation preferences defining the one or more particular formats;
• and
• means for presenting, via the computing device, the one or more items in the one or more particular formats.
