Abstract
A device for assisting a user to perform a transaction on a machine is described. The device receives data that specifies a transaction mode to use for processing an image and accesses a knowledge base to provide data to configure the device for the transaction mode, the data including data specific to the transaction mode. The device receives an image or images of a portion of a machine that the user will use to perform the transaction and processes the image or images to identify a pattern of controls on the machine and to detect the presence of a user-controlled pointing item over controls on the machine. The device announces to the user the name or function of the control closest to an end of the user-controlled pointing item.
