approaches that exist to assess the visual aesthetics of the interactive products presented to users, one of which involve the selected results of two kinds of studies reported in [10], that used the dimension of classical aesthetics proposed by the research work. This is to properly present the relation of perceived visual aesthetics to the perception of the usability, emotional response and consequences of user experience [4, 15, 16]. Research work on overall preference and satisfaction from assess replication to evaluating user reaction (**Figure 2**), as clearly stated steps torwards control service customisation to aesthetics and object identification.

Also, it has been argued that the components associated with usability, such as satisfaction, effectiveness, and efficiency, are never a sole forecast for user experience [17, 18]. The inclusion and assessment of hedonic and pragmatic features regarding user experience technology study about interaction based on pleasure, engagement, pleasure, fun, and games. For mobile devices, it is clear that they have a set of features such as GPS, touch screen and cameras over games consoles that allows for different mode of interactions. Few research as [4, 10, 19–21] stated that aesthetics has demonstrated a positive effect on user perception on mobile system's ease of use, for enjoyment and usefulness. However, the impact of the degree of visual aesthetic quality, which could be high or low on perceived usability is not clear. [22–25] conducted an experiment in the e-commerce domain to explore the hedonic and practical motivation and engagement including both functional and pleasurable aspects of user experience and the hedonic qualities of the colour object properties such as practical and entertaining concepts together with efficiency, functional attributes, cost and influential user engagement. Consequently, there are different kinds of study that have been conducted to assess visual aesthetics and user experience in areas of online news, video games and web surfing. These areas examine the quality of information interactions from users' perspectives. By contrast, perceived aesthetics, usability and focused attention emerged to be typically different from all other visual experience study. Some papers [12, 18] made recommendation on how to make use of fewer constructs in user experience scale on visual aesthetics. Hence, this scale was reduced to four factors which include aesthetics, reward, focused attention and perceived usability. Aesthetics as defined by [19, 20, 26], as the sensuous qualities, the experiences and the emotions that occur while interacting with a colour objects. Visual aesthetics refers to the

In the research paper by [5–7], they described their integrated research approach to the experimental study of emotional user reactions in consideration of the influential and non-influential quality perceptions of the interactive systems. In this chapter, a model is presented that equally defines instrumental and non-

instrumental quality perceptions which are the same as the emotional reactions. The interactive features primarily depend on the system properties but also on the user perceptions and context parameters. The main consequence of a users' perception on visual aesthetics of any color object is based on their behaviour or preferences which are centralised components of user experience. The aesthetics aspect of the non-instrument quality is divided into different dimensions which are related to human senses. The visual, auditory and haptic perception are very important in human emotion-technology interaction and these are stated in [8–11]. Visual aesthetics of materials and products is defined as the extent of which the sensory and formal colors and shape attributes of the product that provides positive visual experience for the users. The visual aspects of products have often been stated as most relevant for users aesthetic response as stated by [12–14]. There are various

appearance that user interface depicted, as the top-most visible surface layer of the user experience on user experience modelling [4, 22]. So, perceived usability is defined as the ease of use, goals of efficiency and the practical side of colour object products including satisfaction in specific contextual use of these products. The work we presented tends to use these design goals to shape the way user view objects they observed and how to modify new methods and ways to understand user visual experience on a biologically defined point of view.
