A teletaction system uses a tactile display to present the user with information about texture, local shape, and/or local compliance. Current tactile displays are at and rigid, and require precise machining and assembly of many parts. This paper describes the fabrication and performance of a one-piece pneumaticallyactuated tactile display molded from silicone rubber. Tactor spacing is 2.5 mm wi...

In recent years audio tactile diagrams have emerged as a viable method of providing blind learners with access to diagrammatical material. It has proven beneficial, but obstacles remain to its widespread adoption, especially in situations where a teacher may not be skilled in tactile production. Current approaches to audio tactile production contain limitations in various areas namely reusabili...

Tactile displays are used to provide tactile feedback in telemanipulation or virtual reality. One aim in further developments is the miniaturisation of tactile displays for incorporation into dataand/or force feedback gloves. This enables the combination of tactile and kinesthetic feedback. A main disadvantage of many tactile displays with a large number of stimulator elements is their large vo...

To investigate whether the mechanisms underlying endogenous tactile spatial attention differ under pure tactile compared to mixed modality conditions event-related brain potentials (ERPs) were recorded to bilateral tactile and visual cues and tactile imperative stimuli. In the cue-stimulus interval the anterior directing attention negativity (ADAN) was present contralateral to the side of the a...

Spatial origin is an important cue for humans to determine whether auditory and tactile signals originate from the same event/object or not. This paper addresses spatial factors involved in the integration of auditory and tactile information. Perceptual threshold values for auditory-tactile spatial origin disparity were measured using tactile information and sound such as those generated by tou...

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...
