Perceptual Decomposition of Virtual Haptic Surfaces
couples the human operator to a source of mechanical power—either electromagnetic, electrohydraulic, or electropneumatic actuators. The computation engine governs the behavior of the actuators and linkage as a function of kinematic and force measurements from interface transducers, according to algorithms and equations that describe the VE models to be simulated. A force reflecting interface th...
متن کاملSensitivity to depth relief on slanted surfaces.
The finest stereoacuity is known to depend on the disparity of a target relative to other visible points. Here we show that a more important factor in determining sensitivity to displacement can be the disparity of a target relative to an invisible interpolation plane through other neighboring points. We tested the sensitivity of observers to displacements of the central column of a regular gri...
متن کاملChange detection for objects on surfaces slanted in depth.
Change detection for objects associated with a surface extended in depth might be more difficult than for a frontal surface if it is easier to shift attention within a frontal surface. On the other hand, previous research has shown that ground surfaces have a special role in organizing the 3-D layout of objects shown against scene backgrounds. In the current study, we examined whether a frontal...
متن کاملA visual-haptic Necker cube reveals temporal constraints on intersensory merging during perceptual exploration.
When viewing a three-dimensional Necker cube with one eye, participants can experience illusory reversals even while they feel the cube with their hands. This surprising property of the visual-haptic Necker cube affords a unique opportunity to investigate temporal constraints on interactions between vision and touch during extended observation of a three-dimensional object. Our observers report...
متن کاملPerceptual Design of Haptic Icons
The bulk of applications for haptic feedback employ direct rendering approaches wherein a user touches a virtual model of some “real” thing, often displayed graphically as well. We propose a new class of applications based on abstract messages, ranging from “haptic icons” – brief signals conveying an object’s or event’s state, function or content – to an expressive haptic language for interpers...
