As far as users' perception of dynamism goes, this latter clip and the action movie received similar across the board satisfaction ratings. As concerns the news clip, users were annoyed at the newscaster's visible lack of lip synchronisation and thus, even though it was a static clip, only gave it average values as far as satisfaction is concerned. Users then essentially treated the bulletin as an audio broadcast, proof being the consistently high percentages of correctly answered questions related to the audio clip of this particular clip. In our view this is comprised of a user's perception of multimedia presentations together with the benefit of such presentations from a user's angle in terms of content assimilation and understanding. This observation has implications on resource allocation.
Users have difficulty in absorbing audio, visual and textual information concurrently.
Users tend to focus on one of these media at any one moment, although they may switch between the different media. This implies that critical and important messages in a multimedia presentation should be delivered in only one type of medium, or, if delivered concurrently, should be done so with maximal possible quality. Highly dynamic scenes, although expensive in resources, have a negative impact on user understanding and information assimilation. Questions in this category obtained the least number of correct answers. However the entertainment value of such presentations seem to be consistent, irrespective of the frame rate at which they are shown.
