In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly.

HTML5, supporting the WebGL standard, allows the exploration of 3D spatial models using most used Web browsers like Chrome, Firefox, Safari, Internet Explorer. The methodological workflow here described has been tested for the construction of a multimedia geo-spatial platform developed for three-dimensional exploration and documentation of the ancient theatres of Segesta and of Carthage, and the surrounding landscapes. The experimental application has allowed us to explore the potential and limitations of sharing on the Web of 3D CH models based on WebGL standard.

Multimodal access to information contents enables the creation of systems with a higher degree of accessibility and usability. A multimodal interaction may involve several human interaction modes, such as sight, touch and voice to navigate contents, or gestures to activate controls. We first start our discussion by presenting a timeline of cultural heritage system evolution, spanning from 2001 to 2008, which highlights design issues such as intelligence and context-awareness in providing information. Then, multimodal access to contents is discussed, along with problems and corresponding solutions; an evaluation of several reviewed systems is also presented. Lastly, a case study multimodal framework termed MAGA is described, which combines intelligent conversational agents with speech recognition/synthesis technology in a framework employing RFID based location and Wi-Fi based data exchange. textcopyright 2010, IGI Global.},
