A mobile device comprising: a text detection component, wherein the text detection component is programmed to detect that text is within view of a camera of the mobile device; a capture component, wherein the capture component is programmed to capture an image of the text in response to receiving a signal from a device operation component that indicates modified operation of the mobile device; an identification component, wherein the identification component is programmed to identify the text or an object that contains the text within the captured image; an action component, wherein the action component is programmed to perform an action associated with the identified text or the object that contains the text; and a detection component, wherein the detection component is programmed to measure a relative orientation between a rendered document and the mobile device using an orientation or position tracking component; wherein the device operation component is programmed to automatically transition the mobile device to a document capture mode in response to receiving a signal from the detection component that indicates the measured relative orientation is within a threshold relative orientation associated with the document capture mode; characterized in that the threshold relative orientation is determined by performing an analysis of previous occurrences of the mobile device in document capture mode for a user of the mobile device based upon stored relative orientation data associated with the previous occurrences, wherein the analysis includes: analyzing occurrences when the user of the mobile device rejected automatic launching of an application that performs actions in response to text captures; and analyzing occurrences when the user of the mobile device manually launched the application that performs actions in response to text captures; a text detection component, wherein the text detection component is programmed to detect that text is within view of a camera of the mobile device; a capture component, wherein the capture component is programmed to capture an image of the text in response to receiving a signal from a device operation component that indicates modified operation of the mobile device; an identification component, wherein the identification component is programmed to identify the text or an object that contains the text within the captured image; an action component, wherein the action component is programmed to perform an action associated with the identified text or the object that contains the text; and a detection component, wherein the detection component is programmed to measure a relative orientation between a rendered document and the mobile device using an orientation or position tracking component; wherein the device operation component is programmed to automatically transition the mobile device to a document capture mode in response to receiving a signal from the detection component that indicates the measured relative orientation is within a threshold relative orientation associated with the document capture mode; characterized in that the threshold relative orientation is determined by performing an analysis of previous occurrences of the mobile device in document capture mode for a user of the mobile device based upon stored relative orientation data associated with the previous occurrences, wherein the analysis includes: analyzing occurrences when the user of the mobile device rejected automatic launching of an application that performs actions in response to text captures; and analyzing occurrences when the user of the mobile device manually launched the application that performs actions in response to text captures; analyzing occurrences when the user of the mobile device rejected automatic launching of an application that performs actions in response to text captures; and analyzing occurrences when the user of the mobile device manually launched the application that performs actions in response to text captures;
