Abstract

Disclosed is a wearable computing eyeglass that switches between transparent view and computer screen projection based on the style and size of the text the wearer is perusing and the lighting conditions. The system monitors eye gaze and physical positioning to determine whether the user will have or is having difficulty reading the text.

A Wearable Computing Eyeglass that Assists in Legibility

Many documents and pamphlets come with different font sizes and styles on the same page. It becomes difficult for any regular eyeglass wearer to read everything using the same corrective lens. The user often has to adjust head position or posture to read the documents. This is particularly difficult in a crowded place such as a museum . In addition, light reflecting off the document can disrupt the readability .

This problem is solved by using a wearable computing eyeglass that switches between transparent and computer screen based on the style and size of the text the wearer is perusing, as well as the lighting conditions. It tracks the eye gaze of the wearer and

when the font or the size becomes too small for the user to read comfortably , it automatically switches to a computer screen and projects the text using a camera on the front at a size that is comfortable for the user to read . It detects the user discomfort by motions of the head or the posture of the user .

The steps for implementing the novel method and system follow :

1. Identify the part of the text that the user is reading by monitoring and identifying the user's eye gaze. The system follows the user's eye gaze using a camera as

well as neck position and standing posture. The system proactively determines

which part the user will read next. It pre-evaluates the section for the lighting condition, glare, font size, and type.

2. Decide diffi...
