Haptic perception [PDF]

open access: yesWIREs Cognitive Science, 2013
AbstractFueled by novel applications, interest in haptic perception is growing. This paper provides an overview of the state of the art of a number of important aspects of haptic perception. By means of touch we can not only perceive quite different material properties, such as roughness, compliance, friction, coldness and slipperiness, but we can also

A Complementary Effect in Active Control of Powertrain and Road Noise in the Vehicle Interior

open access: yesIEEE Access, 2022
This study shows that a concurrent active noise control strategy for engine harmonics and road noise has a complementary effect. In particular, we found that engine booming noise is additionally attenuated when road noise control is concurrently used ...
