Regulation of emotions: It is the control and regulation of personal and other people s emotions for the emotional and intellectual development; it is the human s ability to realize what is hidden behind an emotion, like fear, anxiety, anger, or sadness, and to find each time the most suitable ways to confront them. Self control: It includes processes referring to the control of attention,the provision of intellectual resources, and the selection of the specialized procedures and skills liable for the evaluation of a problem s results or a decision s uptake; it is a superior control system thatcoordinates the functioning of other, more specialized control systems. These parameters must be filtered even more so that the final optimized model is achieved. Once this is established, a series of tests (some in the form of questionnaires and others with real-time interaction metrics) will be constructed which will attempt to reveal users perceptual preference characteristics. These features, along with the Traditional User Characteristics, could complete the New User Profile, and therefore adaptation and personalization schemes could be adjusted to deliver even more personalized Webbased content accordingly. The next step is to identify what is the correlation between the various users and/or user groups (i.e., to investigate similarities and differences between them) and if it would be feasible to refer to the term users segmentation (i.e., users sharing similar new user profiling characteristics). In case the latter is true, personalization mechanisms will be based upon these parameters and considering users device/channel characteristics, and the semantic content will provide them with the corresponding adapted result. Eventually, this methodology will be implemented with personalization algorithms and paradigms so to automatically gather all the related information and construct the new user profiling, giving the users the adapted and personalized result without their actual intervention. Summary and Future Trends When referring to adapted multimedia-based services or Web-based multimedia content provision, it is implied that the content adaptation and personalization is based not only on the traditional user characteristics, but on a concrete and comprehensive user profiling that covers all the dimensions and parameters of the users preferences. However, knowing the user traditional characteristics and channel/device capabilities, providers can design and offer an apt personalized result. Most of the times, though the providers tend to design multimedia applications based on their own preferences and what they think should be offered. However, the concept of adaptation and personalization is much more complicated than that. This is the reason why until today there is not any sustainable related definition of personalization. A profile can be considered complete when it incorporates the users perceptual preference characteristics that mostly deal with intrinsic parameters and are very difficult to be technologically measured. Visual attention (that can be thought of as the gateway to conscious perception and memory) and cognitive psychology processes (cognitive and emotional
