| Popis: | People suffering from low vision, a condition caused by a variety of eye-related diseases and/or disorders, find their ability to read greatly improved when text is magnified between 2 and 6 times. Assistive devices currently on the market are either geared towards reading text far away (∼20 ft.) or very near (∼2 ft.). This is a problem especially for students suffering from low vision, as they struggle to flip their focus between the chalkboard (far-field) and their notes (near- field). A solution to this problem is of high interest to eye care facilities in the developing world - no devices currently exist that have the aforementioned capabilities at an accessible price point. Through consultation with specialists at L.V. Prasad Eye Institute in India, the authors propose, design and demonstrate a device that fills this need, directed primarily at the Indian market. The device utilizes available hardware technologies to electronically capture video ahead of the user and zoom and display the image in real-time on LCD screens mounted in front of the user's eyes. This design is integrated as a wearable system in a glasses form-factor. |
