Impact of Cognitive Style on User Perception of Dynamic Video Content

Notions of quality are of paramount importance in distributed multimedia systems – simply stated, a user will not invest time, money or, indeed, other resources if (s)he does not believe that (s)he is getting quality commensurate with expectations. Whilst efforts to characterize distributed multimedia quality have been forthcoming along the years (Apteker et al., 1995; Cranley et al., 2003; Steinmetz, 1996; Wilson and Sasse, 2001), the proliferation of multimedia applications, display devices and – last but certainly not least – users, have led researchers to investigate novel ways of exploiting perceptual quality measures to transmit bandwidth-intensive multimedia content over fixed size pipes to an increasing numbers of users. Information transfer constitutes, in most cases, an important side of multimedia applications. Nonetheless, a dimension that is often overlooked in such cases, particularly in respect of quality considerations is the one of cognitive ABSTRACT
