....on the lowest level. Hints of the layered framework are also present in, for example, 18] and [7] who di#erentiate between perceptual QoS (QoE) application QoS (Layer 7 and 8 concerns) and Network QoS (Layer 5 and lower) which is a clear step towards the present thinking (see also, [6][13] 14] 24] HCI evaluation methods such as task analysis and GOMS (Goals, Operators, Methods, and Selection rules) 12] also have a similar flavour, although they are often focused on Layer 8 issues and fail to capture the high level user needs we describe in Layer 10. Also, the term QoE is not ....

....quality impairment (Level 5) down to very annoying quality impairment (Level 1) 2, 20, 44] With these approaches, users can easily select the level of quality desired at a very high level of abstraction, perhaps using slide bars, radio buttons, or some other graphical mechanism. In work such as [1, 13], studies have been carried out to determine how human users would map these quality levels into lower level quality metrics for a variety of applications. For example, in subjective tests detailed in [1] users of video applications rated quality provided by the applications at different frame ....
