This paper explores the use of a physics-based sound model of continuous contact for auditory display in interactive settings. An audio-visual interactive display is developed in which the sound model is controlled by the user’s gestures. The display is used to investigate to what extent audition can substitute for haptic feedback in conveying perception of inertial properties of a manipulated ...

The vestibular system--a sensor of head accelerations--cannot detect self-motion at constant velocity and thus requires supplementary visual information. The perception of self-motion during constant velocity movement is completely dependent on visually induced vection. This can be linear vection or circular vection (CV). CV is induced by large-field visual motion stimulation during which the s...

Virtual Environments (VE) represent advanced human computer interaction systems, communicating over several channels of information. The basic terms we need to describe human VE interaction are “communication channel” and “multimodality”. The communication channel is as a pathway between the user and the simulation that mediates the interaction. Multimodality is the quality of a system, which a...

INTRODUCTION Verticality is essential in our life, especially for postural stability. Subjective vertical as well as postural stability depends on different sensorial information: visual, vestibular and somesthesic. They help to build the spatial referentials and create a central representation of verticality. Children are more visuo-dependant than adults; however, we did not find any study foc...

Objectives To compare the effectiveness of the topical administration of benzocaine and EMLA on oral pain and tactile sensitivity. Materials and Methods A randomized, double-blind, split-mouth clinical trial was carried out with 20 volunteers. The sensorial and quantitative tests were applied before the contact with topical anesthetic and after the application. Results In the superficial ta...

BACKGROUND Cochlear implant in children, speech perception and oral language, hearing and oral language performance in children with pre-lingual profound sensory-neural hearing impairment, users of cochlear implant. AIM To study the hearing and oral language performance of children with pre-lingual bilateral profound sensory neural hearing impairment, users of multi-channel cochlear implant c...

User’s perception of product, by essence subjective, is a major topic in marketing and industrial design. Many methods, based on users’ tests, are used so as to characterise this perception. Methods like multidimensional scaling, semantic differential method, and preference mapping are well known in sensorial analysis or in the food industry. These methods are used in order to built a perceptua...

This paper presents an integrated approach to tactile perception, both in terms of data acquisition and of data interpretation. In humans, touch sensing is implemented through a number of different sensing elements embedded in: the skin. The interpretation of perceived data to the level of detection of basic features, such as material, shape of surjface, shape of contact, is achieved by integra...

Immersion in an illusory world is possible by means of virtual reality (VR), where environmental perception is modified by artificial sensorial stimulation. The application of VR for the assessment and rehabilitation of pathologies affecting the vestibular system, in terms of both diagnosis and care, could represent an interesting new line of research. Our perception of reality is in fact based...
