Psychophysical Scaling of Sonification Mappings with Blind and Visually Impaired Listeners
We used magnitude estimation to determine preferred datato-display mappings, polarities, and psychophysical scaling functions relating perceptual and conceptual data values to underlying acoustic parameters for blind and visually impaired listeners. We compare the resulting scaling functions to previous findings with sighted participants [1]. The findings have implications for the design of fut...
متن کاملImage Quality Scaling for Electrophotographic Prints
Two psychophysical experiments were performed scaling overall image quality of black-and-white electrophotographic (EP) images. Six different printers were used to generate the images. There were six different scenes included in the experiment, representing photographs, business graphics, and test-targets. The two experiments were split into a pairedcomparison experiment examining overall image...
متن کاملPsychophysical Scaling of Sonification Mappings
We determined preferred data-to-display mappings by asking experiment participants directly and then examined the psychophysical scaling functions relating perceived data values to underlying acoustic parameters. Presently, we are extending and validating the scaled mappings in practical data interpretation tasks. The resulting scaling functions, in conjunction with the experimental paradigm de...
متن کاملPsychophysical Scaling of Sonification Mappings: a Comparision of Visually Impaired and Sighted Listeners
Magnitude estimation was used to determine preferred datato-display mappings, polarities, and psychophysical scaling functions relating data values (like temperature) to underlying acoustic parameters (like pitch, tempo, or spectral brightness) for blind and visually impaired listeners. The resulting polarities and scaling functions were compared to findings with sighted participants. There was...
متن کاملAchieving across-laboratory replicability in psychophysical scaling
It is well known that, although psychophysical scaling produces good qualitative agreement between experiments, precise quantitative agreement between experimental results, such as that routinely achieved in physics or biology, is rarely or never attained. A particularly galling example of this is the fact that power function exponents for the same psychological continuum, measured in different...
