Designing an advanced approach of multimedia content formatting is necessary for limited devices that can not handle and process the content. Until now, the adaptation process that we have realized in the NAC architecture doesn't consider the adaptation process at a low level (formatting process). So, in some situations, the adapted content could not be presented correctly in a very limited environment such as in mobile phones platforms.
Our approach enriches the NAC architecture by new adaptation techniques that consider the formatting process and the interaction of the user. The formatting process is responsible to present the content and handle the presentation layout according to the device limitations.
To avoid the problem of loosing the content fidelity regarding the original content (that occurs as a result of the content transformation from a state to another state), the interaction process enables the user to interact with the original content with maintaining the adaptation of each partial result. According to the user interaction, the adaptation process could send a part of the original content and guarantees that the content parts remain adapted to the device profile.

We give here some screenshots of our experimentations performed on a mobile phone running on a J2ME platform : MIDP 1.0 and CLDC 1.0. (Click on the photo to enlarge it)
