Stability of Haptic Displays
Haptic displays can be considered to be devices which generate mechanical impedances. ‘Impedance’ here is defined as a dynamic relationship between velocity and force. The behavior of the haptic display depends on the virtual environment being rendered. For instance, if the desired behavior is that of a point mass, the haptic display must exert forces proportional to acceleration. Similarly, if...
متن کاملIntelligent Control for Haptic Displays
Usually, a mouse is used for input activities only, whereas output from the computer is sent via the monitor and one or two loudspeakers. But why not use the mouse for output, too? For instance, if it would be possible to predict the next interaction object the user wants to click on, a mouse with a mechanical brake could stop the cursor movement at the desired position. This kind of aid is esp...
متن کاملTwo Recommendations for Tactile/Haptic Displays: One for All Kinds of Presentations and One for the Development of Haptic Displays
Two recommendations are suggested. The first is general for all kinds of tactile/haptic presentations when vision is not available and concerns the need of an overview of the scene. The suggestion is that efforts to facilitate overview should be made in all kinds of tactile/haptic presentations. The second concerns the development of haptic displays. It is suggested that the efforts for improve...
متن کاملStability and Performance of Haptic Displays: Theory and Experiments
In haptic simulation, a human operator kinesthetically explores a virtual environment. To achieve a virtual sense of touch, the human interacts with an active mechanical device, called a haptic display. This paper presents an approach to guarantee that this physical manmachine interface remains stable, while maximizing performance. The key element in ensuring stability is the virtual coupling n...
متن کاملImplementation of Arbitrary Path Constraints Using Dissipative Passive Haptic Displays
The problem of applying an energetically passive dissipative haptic interface to a path-following application is addressed. This consists of controlling a man-machine system where the human operator provides all motive power, and the machine may dissipate or redirect this power. The goal of a controller is to constrain the operator-induced motion to a single arbitrary degree-of-freedom. This re...
