This document discusses the role of technology in children's museums. It begins by asking why technology should be used, what role it can play, and how it can be implemented. Potential reasons for using technology include expanding visitor experiences through space, time and access to intangible heritage. Technology can be both a means and an end, and involve cutting-edge tech or human mediation. Innovators in the field include private companies, new media art centers, and museum laboratories. The fundamental question remains why technology has a place in children's museums in the era of ubiquitous computing.
