Tactile experiences of textile materials are difficult to communicate and elicit. To interrogate this space we propose the tactile triangle, a framework to facilitate systematic analysis and comparison of tactile experiences. The three levels reflect different aspects of tactile experience and possible methods to capture them: physical properties, in which human senses or objective testing meas...

Sensory processing abnormalities in autism have largely been described by parent report. This study used a multi-method (parent-report and measurement), multi-trait (tactile sensitivity and attention) design to evaluate somatosensory processing in ASD. Results showed multiple significant within-method (e.g., parent report of different traits)/cross-trait (e.g., attention and tactile sensitivity...

We present an electrostatic tactile display for stimulus localization. The 240-Hz electrostatic force was generated by the beat phenomenon in a region where excited X electrodes cross excited Y electrodes, which presents localized tactile sensation out of the entire surface. A 10.4in. visual-tactile integrated display was successfully demonstrated. key words: tactile display, electrostatic forc...

Piezoelectric vibratory tactile sensors are used for measuring the softness and hardness of an object. In this research, the sensitivity of the longitudinal bar type tactile sensor was considered to establish the design guideline of the vibratory tactile sensor. First, the sensitivity on the frequency change of the longitudinal bar resonator in contact with an object was approximately derived f...

BACKGROUND Following the inclusion of sensory abnormalities in the diagnostic criteria for autism, evidence has emerged showing that tactile abnormalities in young children with autism are severe, universally present, and directly related to delay of early self-regulation milestones required for social development. Parent touch is the most effective means of stimulating early self-regulation, y...

Perceptual completion is a fundamental perceptual function serving to maintain robust perception against noise. For example, we can perceive vivid experience of motion even for the discrete inputs across time and space (apparent motion: AM). In vision, stimuli irrelevant AM are suppressed smooth along trajectory where no physical applied. We investigated whether such masking induced by dynamic ...

There is concurrent evidence that visual reach targets are represented with respect to gaze. For tactile reach targets, we previously showed that an effector movement leads to a shift from a gaze-independent to a gaze-dependent reference frame. Here we aimed to unravel the influence of effector movement (gaze shift) on the reference frame of tactile stimuli using a spatial localization task (ye...
