Magnetorheological Brake for Haptic Rendering

Lecture Notes in Computer Science, 2008
This paper addresses the design and characterization of a single-disk magnetorheological fluid brake developed for haptic rendering. An analytical method was used for dimensioning. Brake is tested under constant current and velocity inputs. We observe that torque has a low dependence on velocity and that it has a hysteretic evolution with current as a ...

Haptic Rendering of Juggling with Encountered Type Interfaces

Presence: Teleoperators and Virtual Environments, 2011
Haptic interaction in a virtual world can be tool mediated or direct; and, among direct interactions, the encountered haptic interfaces provide physical contact only when there is contact with a virtual object. This paper deals with the haptic rendering of the catching and throwing of objects by means of this type of interface. A general model for the

Introduction to haptic rendering

ACM SIGGRAPH 2005 Courses on - SIGGRAPH '05, 2005
For a long time, human beings have dreamed of a virtual world where it is possible to interact with synthetic entities as if they were real. To date, the advances in computer graphics allow us to see virtual objects and avatars, to hear them, to move them, and to touch them.

Haptic rendering of photographs

2012 IEEE International Workshop on Haptic Audio Visual Environments and Games (HAVE 2012) Proceedings, 2012
Exploration of 2-D images is a challenging problem in computer haptics and research has primarily been focused on the exploration of restricted types of images, e.g., maps or mathematical curves. In contrast, this paper describes the design and implementation of a system for the haptic exploration of general photographs.

Sensation-preserving haptic rendering

IEEE Computer Graphics and Applications, 2005
Most human-computer interactive systems focus primarily on the graphical rendering of visual information and, to a lesser extent, on the display of auditory information. Haptic interfaces have the potential to increase the quality of human-computer interaction by accommodating the sense of touch.

Haptic Rendering of Compliant Shapes

IEEE Transactions on Robotics, 2015
Dynamically controlling the shape of an object by means of a 3-D shape interface offers many new opportunities in the fields of virtual reality and design as direct exploration of objects becomes feasible. Using a parallel kinematics as 3-D shape interface comes with features such as high stiffness and speed, but requires a series of points to be ...

Velocity driven haptic rendering

Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia, 2005
This paper presents a compact method for improving haptic rendering in virtual environments using Level Of Detail (LOD) with force feedback. We have introduced a velocity driven LOD, a new concept in using LOD in haptics. The aim of this approach differs from using LOD techniques in graphics.

Haptic rendering

Proceedings of the 1995 symposium on Interactive 3D graphics - SI3D '95, 1995
Haptic rendering is the process of computing and generating forces in response to user interactions with virtual objects. Recent efforts by our team at MIT's AI laboratory have resulted in the development of haptic interface devices and algorithms for generating the forces of interaction with virtual objects.

Physically-inspired haptic rendering

Proceedings of the 2006 ACM international conference on Virtual reality continuum and its applications, 2006
Extending the frontier of visual computing, real-time physically-based interactions and haptic (touch-enabled) rendering have the potential to increase the quality of man-machine communication. By accommodating the sense of touch and introducing realistic modeling of physical elements, haptic interfaces provide an attractive augmentation to visual ...
