Automatic text scrolling on a display device

摘要

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.
