In this paper, we first argue that "experiential quality" and "Quality of Experience" are synonymous concepts, bridging the gap of quality assessment between design and storytelling with multimedia systems. We then survey the literature where experiential qualities play a significant role in interaction design and storytelling. Finally, we summarize the available measurements of experiential qualities and categorize them into four dimensions, namely, qualitative vs. quantitative, subjective vs. objective, design-based measures vs. neuropsychological-based measures, and systems approach vs. human factors approach, with a hope of further inferring and improving the measurability and predictability of "experiential qualities" and including this in future QoE assessment methodologies for sensor based digital storytelling in future studies.
