Study on Tactile Perception of Shape for Effective Tactile Display
نویسندگان
چکیده
The experiment of the shape recognition for a tactile display is carried out and analysed in this paper. The purpose of this research is the development of a tactile stimulator array to represent the obstacle information for the visually impaired to walk safely. As a first step of this research, we investigate the characteristics of tactile stimuli and design the experimental system for the physiological characteristic test based on the investigated results. In order to determine the appropriate and optimal range of the actuating frequency and displacement for the tactile stimulation array, the psychophysical experiment for the threshold of perception and recognition ability of multi-stimulation with some shapes are carried out by the estimation of the subject group. As a result the appropriate tactile stimulus intensity and frequency of the tactile stimulation array to recognize arbitrary line shapes effectively are discussed and derived. Copyright © 2005 IFAC

The Application of Tactile Experience in Urban Perception
Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...
متن کاملDesign and Modeling of a New Type of Tactile Sensor Based on the Deformation of an Elastic Membrane
This paper presents the design and modeling of a flexible tactile sensor, capable of detecting the 2D surface texture image, contact-force estimation and stiffness of the sensed object. The sensor is made of polymer materials. It consists of a cylindrical chamber for pneumatic actuation and a membrane with a mesa structure. The inner radius of the cylindrical chamber is 2cm and its outer radius...
متن کاملTactile agnosia. Underlying impairment and implications for normal tactile object recognition.
In a series of experimental investigations of a subject with a unilateral impairment of tactile object recognition without impaired tactile sensation, several issues were addressed. First, is tactile agnosia secondary to a general impairment of spatial cognition? On tests of spatial ability, including those directed at the same spatial integration process assumed to be taxed by tactile object r...
متن کاملTactile display applications: a state of the art survey
Tactation is the sensation perceived by the sense of touch. Kinesthetic information describes the relative positions and movements of body parts as well as muscular effort when touching and manipulating objects. Haptic perception involves both tactile perception through the skin and kinesthetic perception of the position and movement of the joints and muscles,through the skin of our fingers and...
متن کاملDesign, Modeling, and Construction of a New Tactile Sensor for Measuring Contact-Force
This paper presents the design, modeling, and testing of a flexible tactile sensor and its applications. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the deflection of the membrane with measuring the strain in the membrane with emb...
