Impact of Olfaction on Information Recall

Multimedia lies on an infotainment continuum, using multiple forms of information content to both inform and entertain users. In other words, multimedia applications are usually intended to add to the knowledge of the user, via its information content, as well as to keep the user entertained, i.e. interested or amused. In previous work, the authors have presented details of studies carried out to study the influence of using olfactory media content to augment multimedia applications on user perception and particularly focusing on users’ enjoyment of the multimedia experience. Thus, in this respect, the authors have studied the influence of the use of olfaction in multimedia applications on entertaining users. Consequently, in this chapter, they focus their attention on the influence of using olfaction to augment multimedia applications with regards to the informational aspect of multimedia systems and applications.
