Handheld device for capturing text from both a document printed on paper and a document displayed on a dynamic display device

A method comprising:

• receiving, using one or more visual sensors of a scanner device, information from a dynamic display device;
• and
• transmitting, from the scanner device to a first computer system, an information-request that includes the information from the dynamic display device, wherein the information from the dynamic display device identifies or can be used to identify content to be provided to a scanner-associated device,
• wherein receiving the information from the dynamic display device comprises receiving position information that represents a position on the dynamic display device from which one of the visual sensors is receiving visual information from the dynamic display device.
