Sonification of Spatial Information: Audio-Tactile Exploration Strategies by Normal and Blind Subjects
نویسندگان
چکیده
On the basis of a meta-analysis of existing literature about sonification technologies, new experimental results on audio-tactile exploration strategies of georeferenced sonificated data by sighted and blind subjects are presented, discussing: technology suitability, subjects’ performances, accessibility and usability in the user/technology interaction.

Non-visual exploration of geographic maps: does sonification help?
PURPOSE This study aims at evaluating the effectiveness of sonification as a mean to provide access to geo-referenced information to users with visual impairments. METHOD Thiry-five participants (10 congenitally blind, 10 with acquired blindness and 15 blindfolded sighted) completed four tasks of progressive difficulty. During each task, participants first explored a sonified map by using eit...
متن کاملTactile feedback improves auditory spatial localization
Our recent studies suggest that congenitally blind adults have severely impaired thresholds in an auditory spatial bisection task, pointing to the importance of vision in constructing complex auditory spatial maps (Gori et al., 2014). To explore strategies that may improve the auditory spatial sense in visually impaired people, we investigated the impact of tactile feedback on spatial auditory ...
متن کاملImportance of temporal cues for tactile spatial- frequency discrimination.
While scanning a textured surface with fingers, tactile information is encoded both spatially, by differential activation of adjacent receptors, and temporally, by changes in receptor activation during movements of the fingers across the surface. We used a tactile discrimination task to examine the dependence of human tactile perception on the availability of spatial and temporal cues. Subjects...
متن کاملAudioFunctions: Eyes-Free Exploration of Mathematical Functions on Tablets
It is well known that mathematics presents a number of hindrances to visually impaired students. In case of function graphs, for example, several assistive solutions have been proposed to enhance their accessibility. Unfortunately, both hardware tools (e.g., tactile paper) and existing software applications cannot guarantee, at the same time, a clear understanding of the graph and a full autono...
متن کاملImproved selective and divided spatial attention in early blind subjects.
Spatial attention paradigms using auditory or tactile stimulation were used to explore neural and behavioral reorganization in early blind subjects. Although it is commonly assumed that blind subjects outperform sighted subjects in such tasks, the empirical data to confirm this remain controversial. Moreover, previous studies have often confounded factors of sensory acuity with those of attenti...
