Studies have shown that, to a large extent, performance of a given perceptual task is independent of the specific sensitivities of the anatomical components used to perform that task. Consequently, the object of calibration—what it is that people become ...

Negative pressure (NP) therapy can effectively manage irregular extremity lymphedema but requires significant physical therapist effort. Considering the repeated work during the therapy, using the NP therapeutic robotic systems is recommended to ...

This paper investigates differences in normal force for different tracing directions on the basis of friction, taking into account individual differences. The normal force and friction coefficient were measured when sixteen participants naturally ...

This paper investigates the influence of contact force applied to the human’s fingertip on the perception of hot and cold temperatures, studying how variations in contact force may affect the sensitivity of cutaneous thermoreceptors or their ...$\mathrm{}{}^{}$$\mathrm{}{}^{}$

We investigated the ability of two fingers to discriminate stiffness with stochastic resonance. It is known that the haptic perception at the fingertip improves when vibrotactile noise propagates to the fingertip, which is a phenomenon called the ...

Perception is not a passive process but the result of an interaction between an organism and the environment. This is especially clear in haptic perception that depends entirely on tactile exploration of an object. We investigate this idea in a ...

Haptic object recognition is widely used in various robotic manipulation tasks. Using the shape features obtained at either a local or global scale, robotic systems can identify objects solely by touch. Most of the existing work on haptic systems ...$\mathrm{}$

Numerous systems based on mid-air gestures have recently been proposed as a digital variant of object manipulation with hands. Simultaneously, however, direct haptic feedback is lost, eliminating an important aspect that we are familiar with from real-...

The present study estimates the perceived midpoint of the forearm by asking participants to judge whether a touched point is closer to the wrist or the elbow. Our results show a perceived midpoint at 51.4% of the forearm length from the wrist, ...

Haptic perception is to identify different targets from haptic input. Haptic data have two prominent features: sequentially real-time and temporally correlated, which calls for a fixed-budget and recurrent perception procedure. Based on an ...

As interest in multimodal and tangible interfaces is increasing in the field of human-robot interaction and virtual reality, haptics has been researched across areas such as engineering, computer science, psychology, and neuroscience. The main objective ...

Various models have been presented for pressures distribution in the contact interface of a soft finger and object in the literature. These models have been proposed without considering the effect of the tangential forces which are usually exerted in ...

Haptic exploratory procedures (EPs) are prototypical hand movements that are linked to the acquisition of specific object properties. In studies of haptic perception, hand movements are often classified into these EPs. Here, we aim to investigate ...

This paper proposes an end-to-end learning from demonstration framework for teaching force-based manipulation tasks to robots. The strengths of this work are manyfold. First, we deal with the problem of learning through force perceptions exclusively. ...

The present study shows an effect of 3D shape on perceived weight of objects. This effect could be explained partly by the size-weight and the shape-size illusions, suggesting that the perceived size is not the only factor responsible for the shape-...

When a small mass in a hand-held device oscillates along a single axis with asymmetric acceleration (strongly peaked in one direction and diffuse in the other), the holder typically experiences a kinesthetic illusion characterized by the sensation of ...

This paper presents the results of a comparative study of user input with a camera-joystick and a manual joystick used in a target acquisition task when neither targets nor pointer could be perceived visually. The camera-joystick is an input technique ...

Three different models of tactile shape perception inspired by the human haptic system were tested using an 8 d.o.f. robot hand with 45 tactile sensors. One model is based on the tensor product of different proprioceptive and tactile signals and a self-...

In order to design a ''haptic zoom'', in this fundamental study, we compare two scaling methods by focusing on the strategies adopted by subjects who are using a sensory substitution device. Method 1 consists of a reduction of the sensor size and of its ...
