Mapping visual display screen to portable touch screen

摘要

A content player transmits a screen image to a display. The screen image includes an active region, which may be a portion that may be manipulated. The player determines active region information for the active region and transmits such to a portable device. The portable device receives the active region information as well as information regarding any inactive regions, which may be portions that may not be manipulated. The portable device utilizes the information to present a simulated version of the screen image on a touch screen. The portable device may then receive manipulation information via the touch screen and transmit such to the player. In response, the player may generate and present an updated version of the screen image, determine updated information, and transmit such to the portable device. The portable device may utilize the updated information to present a simulated updated version of the screen image.

主权项

1. A method executable by a content player device to map visual display screens to touch screens, the method comprising:
providing, by the content player device executing a graphical API, a screen image to a first display associated with the content player device, wherein the screen image includes at least one active region generated by the graphical API in response to a call from the at least one content player that corresponds to a portion of the screen image that is operable to be manipulated by a user input received from a user; identifying, by the processing of the screen image by the graphical API of the content player device, the portions of the screen image that are operable to be manipulated by the user to thereby automatically determine active region information describing the at least one active region, the active region information determined by the graphical API of the content player device including position information about the portion of the screen image that is operable to be manipulated by the user; and transmitting the active region information from the content player device to a portable touch screen device wherein the portable touch screen device presents a simulated version of the screen image on a touch screen display that is different and separate from the first display, wherein the simulated version of the screen image presented on the touch screen display of the portable touch screen device comprises input regions that are mapped to the active regions of the screen image presented on the first display based upon the active region information that was automatically determined by the graphical API of the content player device, and wherein the at least one portable touch screen device accepts the user input corresponding to the active regions from the touch screen display and provides information about the user input accepted from the touch screen display to the content player device so that the user is able to manipulate the portions of the screen image on the first display by using the portable touch screen device.
