EMPERICAL EXPERIMENT DEFINITION AND OPERATIONALSATION OF VARIABLES Contentual deviation Difference of an attribute towards its requrement. The substance of the visualisation (CDe) differs from other parts of the plan in the meaning of different perspecitve proportion or changed design specification. Level of deviation Gradual difference of CDes. Atmospheric effect Features of visualisations like colour and light efffects, relatable objects (people) and human activities These effects primarily evke an emotional reaction of the viewer. Experience The viewer‘s total experience (time and intensity) with profesional visualisations. Focus of attention The viewer‘s directed assimilation of information. FORMATION OF HYPOTHESES Work-hypothesis 1 CDes are not recognised no matter if the focus of attention is on the design or the visual representativeness. Sub-hypothesis 1.1 CDes are not recognised no matter the level of deviation . Sub-hypothesis 1.2 CDes are not recognised no matter the level of atmospheric effect . Sub-hypothesis 1.3 CDes are not recognised no matter the professional experience of the viewer. CONTRADICTORY RENDERINGS | MATTHIAS KLAUSER | DIRK STENDEL | DLA CONFERENCE | 04. - 06.06.2015 6

EMPERICAL EXPERIMENT LEVELS OF CONTENTUAL DEVIATIONS NO QUITE 1 4 DEVIATION Strong deviation Correct contentual and change of transmission relevant information. BARELY VERY 2 5 MUCH Slight change of Barely any objects, perspective consistency between etc visualisation and design AVERAGE 3 Moderate deviation and change of relevant information CONTRADICTORY RENDERINGS | MATTHIAS KLAUSER | DIRK STENDEL | DLA CONFERENCE | 04. - 06.06.2015 8

EMPERICAL EXPERIMENT LEVELS OF ATMOSPHERIC EFFECTS WEAK A EFFECT Looks neutral and sober. Evokes little interest and other emotions MEDIUM B EFFECT Visualisation with medium atmospheric effect STRONG C EFFECT Exeptionally dramatic and aesthetic depiction CONTRADICTORY RENDERINGS | MATTHIAS KLAUSER | DIRK STENDEL | DLA CONFERENCE | 04. - 06.06.2015 9

DATA COLLECTION SURVEYS 1. The urban connection between the river landscape and the surrounding quarters is adequate. 2. The sequence along the riverbank is consistent and can be experienced and the water is accessible. 3. Use and cultue offerings are extended and supplemented in a reasonable way. 4. Qualities of relevant open spaces are emphasized convincingly and are worked out in high detail. 5.a The concept is conclusive and creates an indipendant identity. 5.b The visualisations are representative for the design.
