Introduction Today, more and more different fields are adopting touch screens or touch panels for applications with human/machinery or human/computer interfaces. Figure 1 is a block diagram of a touch-screen system where the touch screen sensor lies on top of the system’s display, in this case an LCD panel. The touch-screen controller in Figure 1 does not need any calibration by itself. However...

Children aged 3-6 years were interviewed following a scheduled pediatric clinic visit to assess the efficacy of two independent variables--interview strategy and number of interviews--on the accuracy, completeness, and consistency of children's reports. Four experimental interviews were created--a verbal interview and three interviews enhanced with anatomically detailed cues (dolls, line drawin...

Skin-Integrated Vibrohaptic Interfaces Haptic technologies add a sense of touch to visual and auditory queues, as the basis for advanced forms virtual augmented reality experiences. In article number 2008805, John A. Rogers, Yei Hwan Jung, Jae-Hwan Kim present recent progress in flexible, skin-integrated haptic interfaces that enable rapid, spatiotemporally programmed perceptions touch, with an...

We show that the affective experience of touch and the sight of touch can be modulated by cognition, and investigate in an fMRI study where top-down cognitive modulations of bottom-up somatosensory and visual processing of touch and its affective value occur in the human brain. The cognitive modulation was produced by word labels, 'Rich moisturizing cream' or 'Basic cream', while cream was bein...

Maavis is a computer framework that provides an extremely simple way to perform common place computer activities like playing media, viewing photos, accessing web information and making video calls. It is ideal for use with a touch screen. A fundamental principal is that it does not appear to be a computer and yet affords access to computer technology that is of benefit and interest to older us...

Interpersonal touch is a fundamental component of social interactions because it can mitigate physical and psychological distress. To reproduce the psychological and physiological effects associated with interpersonal touch, interest is growing in introducing tactile sensations to communication devices. However, it remains unknown whether physical contact with such devices can produce objective...

Spatial perception by dynamic touch is a well-documented capability of the hand and arm. Morphological and physiological characteristics of the foot and leg suggest that such a capability may not generalize to that putatively less dexterous limb. The authors examined length perception by dynamic touch in a task in which weighted aluminum rods were grasped by the hand and wielded about the wrist...

We describe how upper limb amputees can be made to experience a rubber hand as part of their own body. This was accomplished by applying synchronous touches to the stump, which was out of view, and to the index finger of a rubber hand, placed in full view (26 cm medial to the stump). This elicited an illusion of sensing touch on the artificial hand, rather than on the stump and a feeling of own...

BACKGROUND Altering the normal association between touch and its visual correlate can result in the illusory perception of a fake limb as part of our own body. Thus, when touch is seen to be applied to a rubber hand while felt synchronously on the corresponding hidden real hand, an illusion of ownership of the rubber hand usually occurs. The illusion has also been demonstrated using visuomotor ...
