Most commonly used impedance-type haptic interfaces employ open-loop force control under the assumption of pseudostatic interactions. Advanced force control in such interfaces can increase simulation fidelity through improvement of the transparency of the device, and can further improve robustness. However, closed loop force-feedback is limited both due to the bandwidth limitations of force sen...

The feedback upon which operators in teleoperation tasks base their control actions, differs substantially from the feedback to the driver of a vehicle. On the one hand, there is often a lack of sensory information; on the other hand, there is additional status information presented via the visual channel. Haptic feedback could be used to unload the visual channel and to compensate for the lack...

For the visually impaired it is important to acquire knowledge about environments in advance. Haptic-audio interfaces have been proven as appropriate to represent certain types of spatial knowledge in a non-visual manner. This dissertation elaborates on a haptic-audio interface that supports non-visual spatial knowledge acquisition of indoor environments. Three representational layers relevant ...

of the continuous development of computers it ssible to construct various environments. As a an interfaces that allow users to manipulate cts in an intuitive manner, as in the real world, demanded. In this paper, we present a 7 DOF ed haptic interface that allows users to not only bject but also to sense its width. We have a system to utilize the physical action of gripping grasp manipulation i...

The range of human kinematic motion as well as force resolution should be known for design of a haptic device. In addition, a haptic interface can be designed more easily when master and slave devices are the same kinematically. However, human kinematic factors have not been analyzed and applied deeply because of their complexity. Although calibration techniques have been developed, there is a ...

This paper presents a series of kinematic and haptic analyses which lead to the design of a particularly simple, yet useful multi-hand multi-finger haptic interface. We also discuss rendering issues which must be addressed in utilizing it, including and extension of the proxy to more general

The project investigates the potential benefits of multimodal user interfaces for blind students. A multimodal user interface uses the combination of two or more different human senses to interact with computers. The work focused on finding the needs of the interaction model for blind students by using different human modalities, so that they perceive and control information in efficient and ef...

Sightlence is a haptic game interface translation of Pong. The goal of the game design was to answer the question if it’s possible to design computer games that only communicate through the haptic modality, if it’s possible to translate classic computer games to the haptic modality, and if it can be accomplished with ordinary gamepads. The two-fold purpose of answering these questions was to ex...

This paper describes the haptic rendering of a virtual environment by drawing upon concepts developed in the area of teleoperation. A four-channel teleoperation architecure is shown to be an e ective means of coordinating the control of a new 3-DOF haptic interface with the simulation of a virtual dynamic environment.
