Angle discrimination in raised-line drawings.
We investigated the angular resolution subserving the haptic perception of raised-line drawings by measuring how accurately observers could discriminate between two angle sizes under various conditions. We found that, for acute angles, discrimination performance is highly dependent on exploration strategy: mean thresholds of 2.9 degrees and 6.0 degrees were found for two different exploration s...
متن کاملRaised line drawings are spontaneously explored with a single finger.
In this study we examine the strategies used by blindfolded subjects asked to freely explore raised line drawings and identify what is depicted in them. We were particularly interested in how often a single finger is spontaneously used because in several studies subjects are forced to use only one fingertip and the extent to which this restriction may depress haptic perception is unclear. The r...
متن کاملThe influence of picture size on recognition and exploratory behaviour in raised-line drawings.
We demonstrate the influence of picture size on haptic recognition and exploratory behaviour. The stimuli were raised-line drawings of everyday objects. Participants were instructed to think aloud during haptic exploration of the pictures. We measured the delay between initial correct speculation and final correct response. The results indicate that picture size influences accuracy but not resp...

متن کاملHaptic Identification of Raised-line Drawings by Children, Adolescents and Young Adults: an Age-related Skill
Past research involving adult participants has consistently shown that the identification of raisedline drawings through haptics was challenging. In the present study, we used a developmental approach to assess whether this skill was related to age and haptic short-term memory capacity. To that end, we asked sighted children, adolescents, and young adults to identify raised-line drawings of com...
