Proxy-based haptic rendering for underactuated haptic devices

2017 IEEE World Haptics Conference (WHC), 2017
Standard haptic rendering algorithms are not well suited for underactuated haptic devices. They compute forces oblivious of underactuation, and then they simply project the resulting forces to the actuated subspace. We propose instead a proxy-based haptic rendering method that computes displacements in the actuated subspace only, and then translates ...

Rendering of Constraints With Underactuated Haptic Devices

IEEE Transactions on Haptics, 2020
Several previous works have studied the application of proxy-based rendering algorithms to underactuated haptic devices. However, all these works make oversimplifying assumptions about the configuration of the haptic device, and they ignore the user's intent.

Image-Driven Haptic Rendering

2014
Haptic interaction requires the content creators to make haptic models of the virtual objects while it is not always possible or feasible, especially when it comes to using real images or videos as elements of interaction. We, therefore, propose tangible images and image-driven haptic rendering where a displayed image is used as a source of the force ...

Wireless haptic rendering for mobile platforms

2012 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2012
Computer haptics has so far been performed on a personal computer (PC). Off the shelf haptic devices provide only PC interfaces and software drivers for control and communication. The new wave of high capable tablet PCs and high end smart phones introduced new platforms for haptic applications. The major problem was to communicate wirelessly to provide

Perceptual Rendering for Learning Haptic Skills

2008 Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2008
We approach the problem of creating haptic simulators that effectively impart skill without requiring high-fidelity devices by identifying perceptually salient events that signal transitions in the interaction. By augmenting these events, we seek to overcome deficiencies in the fidelity of the rendering hardware.

Visual immersive haptic rendering on the web

Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry, 2008
We propose how to define complex geometry, appearance and tangible physical properties of the X3D and VRML objects using mathematical functions straight in the scene definition code or in loadable libraries. We can also touch and feel surfaces of X3D and VRML objects as well as convert them to solid tangible objects.

A study of level-of-detail in haptic rendering

ACM Transactions on Applied Perception, 2005
This paper presents an initial study of an approach to reduce computational overhead in haptic rendering of physically based models. Haptic rendering refers to the notion of adding physical properties and behavior, specifically a sense of touch or force feedback, to models of objects.

Haptic Rendering of Point Set Surfaces

Second Joint EuroHaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (WHC'07), 2007
We present a haptic rendering algorithm for a point set surface. Given a point set, its point set surface is an implicit surface defined by local projection of point sets using the moving least square (MLS) method. Our haptic algorithm is a penalty-based method which requires a calculation of the minimum distance between the haptic interaction point ...

Fast Rendering for a Multifinger Haptic Display

Second Joint EuroHaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (WHC'07), 2007
An algorithm is described for fast rendering of surfaces for haptic interaction with multiple fingers. The algorithm uses a human-defined geometrical map to quickly cache surface triangles for constant time solution of the collision detection problem. The map is a 1, 2, or 3 dimensional manifold onto which it is easy to project the haptic interaction ...

A framework for the haptic rendering of the human hand

11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003. HAPTICS 2003. Proceedings., 2003
In this paper we present a framework that allows the haptic rendering of interactions between the human hand and a virtual environment consisting of polygonal objects. The proposed solution creates a representation of the human hand through simple geometric primitives (spheres, cylinders etc.) and allows the fast collision detection and calculation of ...
