US Patent 10448111 Content projection

One or more techniques and/or systems are provided for content projection. For example, a communication connection may be established between a primary device (e.g., a smart phone) of a user and a secondary device (e.g., a television). The primary device may identify an interest of the user to view content on the secondary device (e.g., photos for a recently attended concert). The primary device may retrieve the content (e.g., local photos on the smart phone and/or photos remotely retrieved from a social network). The primary device may project a rendering of the content onto a secondary display of the secondary device (e.g., the smart phone may send the rendering over the communication connection to the television for display).
