Hierarchical predictive coding suggests that attention in humans emerges from increased
precision in probabilistic inference, whereas expectation biases attention in favor of …

There is increasing evidence that human perception is realized by a hierarchy of neural
processes in which predictions sent backward from higher levels result in prediction errors that …

In a forced-choice task, we asked human participants to discriminate by touch alone glass
plates from transparent polymethyl methacrylate (PMMA) plastic plates. While the surfaces …

When we touch an object or explore a texture, frictional strains are induced by the tactile
interactions with the surface of the object. Little is known about how these interactions are …

This paper studies the perception of 2-dimensional directional cues presented on a hand-held
tangible interface that resembles a cylindrical handle. The tangible interface is designed …

Fingertip haptic feedback offers advantages in many applications, including robotic
teleoperation, gaming, and training. However, fingertip size and shape vary significantly across …

A realistic keyclick sensation is a serious challenge for haptic feedback since vibrotactile
rendering faces the limitation of the absence of contact force as experienced on physical buttons…

The human perception of square ultrasonic modulation of the finger-surface friction was
investigated during active tactile exploration by using short frictional cues of varying duration …

Metamaterials are solid lattices with periodicities commensurate with desired wavelengths.
Their geometric features can endow the bulk material with unusual properties, such as inter …

Vibrotactile sensations can be used to elicit apparent haptic motion illusions, which consist
in using discrete vibration patterns to convey an illusory continuous moving sensation across …
