This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...

A multi-modal mouse incorporating tactile and force feedback was tested in a target selection task with 12 subjects . Four feedback conditions (normal , tactile , force , tactile 1 force) were combined with three target distances and three target sizes . We found significant reductions in the overall movement times and in the time to stop the cursor after entering the target . This ef fect was ...

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...

This paper presents initial results in integrating touch with vision for delicate manipulation tasks. A generalizable framework of behavioral primitives for tactile and visual feedback control is proposed. Since vision provides position and shape information at a distance, while tactile provides small-scale geometric and force information, we focus on the complimentary roles of vision and touch...

in this paper, design and construction of a tactile sensor for measuring contact-force is presented. mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. by considering a specific point in the circuit and recording the changes of its voltage, ma...

The force/tactile sensation (hereafter referred to as f/t sensation) has not been well defined for a long time. In the applications of real haptics, it is necessary quantitatively evaluate quality sensation. paper proposes definition stimulus signal. Accordingly, instantaneous value signal represents simultaneous ratio reaction force and velocity. If contact target modeled an inertia-damper-spr...

A decoupling method based on radical basis function neural network (RBFNN) for a novel threedimensional force flexible tactile sensor is presented in this paper. A numerical model of the tactile sensor is built through finite element analysis, which simulates the mapping between three-dimensional force applied on top surface of the sensor and deformation of the sensor. Furthermore, the RBFNN is...

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...

Tactile feedback from a remotely controlled robotic arm can facilitate certain tasks by enabling the user to experience tactile or force sensations from the robot's interaction with the environment. However, equipping both the robot and the user with tactile sensing and feedback systems can be complex, expensive, restrictive and application specific. This paper introduces a new tele-operation h...
