Edigma combines precision cameras for finger tracking, multimedia projectors and transparent material to create interactive window displays called Displax. With Displax you can educate consumers about products and services in a dynamic and memorable way. You can enhance the in-store environment and have the flexibility to update all in-store point-of-sale and messages immediately from one source, but you’re also able to target different audiences in different parts of the store at different times of the day. (RPT means Rear-Projection Transparent)
The website has some nice videos online (apparently Rabobank in the Netherlands already has a few active displays)
Visit Displax | Thanks Dave
