Appearance control by projector camera feedback for visually impaired

Visual impairment is a common problem for people worldwide. The projector-based AR technique has the ability to change the appearance of real objects, and it can help to improve visibility for the visually impaired. We propose a new framework for appearance enhancement with a projector camera system that employs a model predictive controller. This framework enables arbitrary image processing such as photo-retouch software in the real world and it helps to improve visibility for the visually impaired. In this article, we show the appearance enhancement results of Peli´s method and Wolffshon´s method for low vision, and Jefferson´s method for color vision deficiencies. Through experimental results, the potential of our method to enhance the appearance for the visually impaired was confirmed to be the same as appearance enhancement for digital images and television viewing.
