Abstract: Provided herein in some embodiments is an apparatus including a rendered information-adjustment module configured to cooperate with a display interface to dynamically size-adjust rendered information displayed on the display screen, a distance module, a vision properties module, and a display modification module. The distance module can be configured to periodically determine a facial proximity to the display screen for the user in accordance with a periodic algorithm. The vision properties module can be configured to collect vision properties and store the vision properties in a vision record for the user. The display modification module can be configured to determine a direction and a magnitude for adjusting the rendered information to a new size. The periodic algorithm conserves the battery power by periodically invoking the one or more facial proximity sensors, which, in turn, reduces otherwise continuous battery power-draining size adjustments to the rendered information on the display screen.

Abstract: Provided herein in some embodiments is a system and a method including a first client-entertainment module of a first mobile-computing device and a first client-entertainment profile associated with the first client-entertainment module. The first client-entertainment module can be configured to cooperate with i) a server-entertainment module on a server computer or ii) a second client-entertainment module on a second mobile-computing device to provide a seamless continuation of entertainment content at a specific point in the entertainment content on the second mobile-computing device. The first client-entertainment profile can be configured to track user interaction with entertainment content and features thereof to provide the specific point for the seamless continuation of the entertainment content.
