The widespread availability of portable computing power and inexpensive digital videocameras opens up new possibilities for helping retailers in a number of markets. One example is in optical shops, where a number of systems exist that facilitate eyeglasses selection. These systems are now more necessary as the market is saturated with an increasingly complex array of lenses, frames, coatings, tints, photochromic and polarizing treatments, etc.

Research challenges encompass Computer Vision, Multimedia and Human-Computer Interaction. Cost factors are also of importance for widespread product acceptance. The low-cost system designed allows the client to visualize different eyeglasses models on a computer or projected screen. Glass models are true-color images obtained from real models. The system is based on a homeostatic image control module (that keeps the image relatively stable under illumination changes), a face and eye detection module and a glass management module. The client can also move the glasses to fit them to the face.
