Ideum multitouch tables are used for a variety of off-the-shelf PC applications, but many of our clients are looking for custom software. We provide a series of HCI software tools that allow other design firms to author their own multitouch and tangible applicatons. Ideum also uses these same tools to develop our own custom exhibits. Designed with flexible and intuitive interfaces, our software is adaptable for multitouch authoring, tangible user interfaces, and audio accessibility features.
