Deriving personal display content from screen capture of primary display
A method acquires a screen capture, as a pixelated image, having text content from a first display on a first display device and processes the acquired pixelated image of the first display using optical character recognition to extract one or more alphanumeric text strings from the displayed text content. The first display device transmits the one or more extracted text strings from the first display to a second display device. At least the one or more extracted text strings are rendered on the second display device.
1 . A method comprising:
(a) rendering an image on a first display device, wherein the first display device is controlled by a first processor;
(b) acquiring, on the first processor, a screen capture, of its rendered image as a pixelated image, comprising text content from its rendered image;
(c) processing the acquired pixelated image using optical character recognition to extract and identify, from the rendered text content, at least a first alphanumeric text string as a label, and a second alphanumeric text string as a variable associated with the identified label;
(d) transmitting, from the first display device to a second display device, the extracted first and second alphanumeric text strings; and
(e) rendering the second alphanumeric text string on the second display device, without rendering the identified label.
2 . The method of claim 1 wherein processing the acquired image further comprises substituting a pre-programmed text string with at least one of the extracted alphanumeric text strings.
3 . The method of claim 1 wherein the first display device is a hand-held device.
4 . The method of claim 1 wherein the first display device is a personal computer.
5 . The method of claim 1 wherein the second display device is a wearable display device that is in wireless signal communication with the first display device.
6 . The method of claim 5 wherein the second display device is a head-mounted display device.
7 . The method of claim 1 further comprising refreshing the first display device in response to activity from a viewer of the second display device.
8 . The method of claim 1 further comprising excluding one or more of the text strings of the first display from extraction.
9 . The method of claim 1 wherein the one or more extracted alphanumeric text strings of the first display are selected according to color.
10 . The method of claim 1 wherein transmitting from the first to the second display device is wireless.
11 . A method comprising:
(a) acquiring a screen capture, as a pixelated image, comprising text content from a display that is a part of a first display device;
(b) processing the acquired pixelated image on the first display device using optical character recognition to obtain one or more alphanumeric text strings, and identifying, from the obtained alphanumeric text strings, one or more keywords from a predetermined set of keywords;
(c) for at least one of the identified keywords identified in the acquired pixelated image, associating a variable text string obtained from the pixelated image and related to the at least one keyword; and
(d) rendering at least the variable text string, and not the associated keyword, on a second display device that is in wireless signal communication with the first display device.
12 . The method of claim 11 further comprising identifying, from the one or more keywords, an instruction or warning and rendering the instruction or warning on the second display device and in a different text font, font size, or color from the variable text string.
13 . The method of claim 11 further comprising defining the predetermined set of keywords according to stored user entries on the first display device.
14 . A hand-held processing apparatus having
a first display;
a processor that controls the first display of the hand-held processing apparatus and that is programmed to acquire a screen capture of the first display as a pixelated image and to identify and extract, using optical character recognition, at least a first alphanumeric text string as a label, and a second alphanumeric text string as a variable associated with the identified label; and
a transmitter that is energizable by the processor to wirelessly transmit the one or more extracted text strings from the hand-held processing apparatus to a remote device having a second display, wherein the remote device is configured for rendering the transmitted second alphanumeric text string, without rendering the associated label.
15 . The apparatus of claim 14 wherein the processor is further programmed to direct the transmitter to wirelessly transmit a portion of the pixelated screen capture image to the remote device.
