Surface tilt perception with a biomimetic tactile sensor
2016 6th IEEE International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2016Humans are known to be good at manipulating tools. To cope with disturbances and uncertainties from the external environment during such tasks, they must be able to perceive small changes in orientation or tilt of the tool using mechanoreceptors in the glabrous skin of the fingertips. We hypothesize that the most sensitive part of human fingers, a flat

Proceedings of the 14th international conference on Human-computer interaction with mobile devices and services companion, 2012
This demonstration accompanies a full paper accepted into MobileHCI '12 [1]. We demonstrate a new type of actuatable display, called a Tilt Display, that provides visual feedback combined with multi-axis tilting and vertical actuation. Its ability to physically mutate provides users with an additional information channel that facilitates a range of new

The Effect of Surface Tilt on Nanoindentation Results
Volume 10: Mechanics of Solids and Structures, Parts A and B, 2007The effect of surface tilt on results of nanoindentation tests is studied for Berkovich, cube corner and conical indenters. The true projected areas are calculated as a function of tilt angle and orientation using the exact three dimensional geometry of each indenter. The true area is compared with the area when there is no tilt and the resulting error

Ultramicroscopy, 2013
Low-energy electron diffraction (LEED) is a widely employed technique for the structural characterization of crystalline surfaces and epitaxial adsorbates. For technical reasons the accessible reciprocal space is limited at a given primary electron energy E.

Slant-tilt: The visual encoding of surface orientation
Biological Cybernetics, 1983A specific form for the internal representation of local surface orientation is proposed, which is similar to Gibson's (1950) "amount and direction of slant". Slant amount is usually quantified by the angle sigma between the surface normal and the line of sight (0 degrees less than or equal to sigma less than or equal to 90 degrees).

Tilt of the Electron Fermi Surface in Bi
Physical Review, 1968Many experiments show that the long axes of the three extremely prolate ellipsoids which represent the electron Fermi surface in bismuth are tilted \ensuremath{\sim}6\ifmmode^\circ\else\textdegree\fi{} from the trigonal plane of the Brillouin zone; however, the sign of this tilt angle cannot be unambiguously obtained from the literature.

Tilt angle effects in surface grinding with mounted points
Production Engineering, 2014Modern 5-axis machining centers enable the development and use of new machining kinematics and grinding strategies to grind workpieces with superabrasives mounted points. One of these technologies is the oscillating surface grinding (OSG), which can improve the surface characteristics and the tribological properties of machined surfaces. In the current

Tilted conic fitting to an off-axis conic surface
Applied Optics, 1991A better fitting to an off-axis conic section can be obtained if a tilted conic is used. The mathematical equation for the tilting angle is obtained as well as the influence over some of the aberration coefficients.

Pronounced overestimation of support surface tilt during stance
Experimental Brain Research, 2005A veridical internal notion of the kinematic state of the foot support is essential for postural control. The means by which this is obtained is still a matter of debate. We therefore measured the conscious perception of support tilt during transient anterior-posterior rotations of a motion platform in six healthy subjects, using a psychophysical ...
