Method for controlling the displaying of text for aiding reading on a display device, and apparatus adapted for carrying out the method, computer program, and computer readable storage medium
First Claim
1. A method for controlling the displaying of text for aiding reading on a display device, comprising the steps of:
- displaying the text on a display screen;
determining, using image processing, a view direction of a user while reading text on the display screen by capturing an image of the user'"'"'s face by a camera, the image processing including segmenting a display screen area into a plurality of segments and determining, using head position processing, to which segment the user'"'"'s gaze is directed, the head position processing including extracting a contour in the captured image and comparing the extracted contour in the captured image with archived contours which have been extracted and archived during a training phase, a best matching archived contour image determines to which segment the user'"'"'s gaze is directed to;
highlighting text in a segment of the display screen which corresponds to the determined view direction; and
tracking the user'"'"'s view direction by successively determining the view direction of the user while reading text on the display screen and successively highlighting text in the corresponding segments of the display screen, wherein the highlighting of text during view direction tracking is started at the beginning of a sentence when the user'"'"'s view is directed to the corresponding segment of the display screen, wherein successively more and more sections of said sentence are highlighted such that when the user'"'"'s view is directed to the end of said sentence the whole sentence is highlighted on the display screen, and wherein the training phase includes;
asking the user to look at certain segments of the display screen;
capturing a corresponding image; and
extracting and archiving the contour corresponding to the head position in the captured image.

Abstract
This invention aims to support the reader in the task of reading text on a display device (21). In each case an area in the text to which the gaze is directed (view areas/focus area of the eyes) is highlighted, respectively. For this purpose the gaze direction is determined (101 to 108) in the reading device (21) and the highlighted region is controlled with gaze direction control (109). When a whole sentence is highlighted, the highlighting is stopped and starts anew with the beginning of the next sentence being read. The highlighted area moves with this technique with the view. The reader'"'"'s eye/brain is thus released from the complicated task of line tracking and can better concentrate on word recognition.
