Automatic text scrolling on a display device
First Claim
1. A head-mounted display device, comprising:
- a microdisplay, the microdisplay projects augmented reality images comprising advancing text to an eye of a user;
a sensor, the sensor tracks a biological metric of the user while the user performs a vocal presentation of the advancing text; and
a control circuit, the control circuit is configured to control the augmented reality images responsive to the biological metric.

Abstract
A see-through head-mounted display (HMD) device, e.g., in the form of glasses, provides view an augmented reality image including text, such as in an electronic book or magazine, word processing document, email, karaoke, teleprompter or other public speaking assistance application. The presentation of text and/or graphics can be adjusted based on sensor inputs indicating a gaze direction, focal distance and/or biological metric of the user. A current state of the text can be bookmarked when the user looks away from the image and subsequently resumed from the bookmarked state. A forward facing camera can adjust the text if a real word object passes in front of it, or adjust the appearance of the text based on a color of pattern of a real world background object. In a public speaking or karaoke application, information can be displayed regarding a level of interest of the audience and names of audience members.

11. A processor-implemented method for providing augmented reality images in a head-mounted display device, the processor-implemented method comprising:
-
controlling a microdisplay associated with the head-mounted display device to emit light to an eye of a user, the light represents augmented reality images comprising advancing text; during the controlling, and while a user performs a vocal presentation of the advancing text, receiving a wireless signal at the head-mounted display device from a wireless terminal of another person; and controlling the augmented reality images, responsive to the wireless signal, to display a message to the eye of the user during the vocal presentation. - View Dependent Claims (12, 13, 14, 15, 16)

17. A processor-implemented method for providing augmented reality images in a head-mounted display device, the processor-implemented method comprising:
-
projecting augmented reality images comprising text to an eye of a user; tracking a gaze direction of the user; in response to the tracking, advancing the text based on the gaze direction of the user; and using a processor; determining a reading speed of the user based on changes in the gaze direction of the user over time, the changes comprise saccades in which the gaze direction of the user moves along a line of the text and a return sweep saccade in which gaze direction moves to a beginning of a next line of the text; and advancing the text based on the reading speed of the user. - View Dependent Claims (18, 19, 20)
