Abstract:
An electronic book system provides interfaces particularly suited to students' use of textbooks. A finger press on a touch screen produces a contextual menu with user choices that relate to where the finger was pressed or what the user was recently doing with the book. A student provisionally navigates through a book by a specific gesture which, when it stops, returns the user to the previous position in the book. Annotations are displayed and hidden using specific gestures and through selective movement of the reader as sensed by its accelerometer.

Abstract:
A content hosting system allows content providers to create channels of video content and make them available to users in a marketplace. Users can search or browse for channels of interest, and selectively subscribe to channels. Users can also pay for the right to view premium videos in each channel. The system ranks channels according to the value provided. Generally, users will seek out and subscribe to the highest ranked channels that provide the greatest value. The ranking function allows different providers to compete for the subscriptions of users. Providers can observe their channel's reception in the market by analyzing rankings and usage statistics to adjust channels to maximize channel performance. The system operator can also create bundled channels containing videos from multiple providers, and the resulting subscription revenue can be distributed to the various providers of the videos in the channel.
