The present study investigated the role of multisensory feedback in the perception of surface roughness, specifically focusing on whether the threshold for distinguishing the roughness of two virtual surfaces was different under visual + haptic conditions, as compared to visual-only or haptic-only conditions. Haptic stimuli were presented via the PHANToM; visual stimuli were presented via computer monitor. The virtual surfaces were sinusoidal gratings that varied in spatial period across trials. Overall, results suggested that threshold was determined by haptic input at low surface amplitudes, and by visual input at high surface amplitudes. At intermediate amplitude values, it appeared that observers were combining information across modalities to produce a percept in the combined condition that was better than that obtained under either single modality condition.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.

The penalty method, which employs a spring-damper model, is a simple and useful method for real-time simulation of multi-bodies. However the simple penalty method cannot handle face-face contact, because the simple penalty method cannot find the application point of the reflection force. We propose a distributed small spring-damper model to solve the problem. We analyze the intersecting part of bodies and integrate forces and torques from distributed spring-damper models. We implement the simulator and compare our simulator with the simple penalty method. It shows that our simulator solves the face-face contact problem. In addition, we attach a haptic interface to the simulator for interaction. It shows that we are able to interact with a virtual world by haptic interfaces.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.

A new algorithm for real-time HMM recognition was developed. The segmentation results are used to provide appropriate assistance in a combined curve following and object avoidance task. This assistance takes the form of a virtual fixture, whose compliance can be altered online. Recognition and assistance experiments were performed using force and position data recorded from a cooperative manipulation system, where a robot and a human operator hold an instrument simultaneously. Recognition accuracy exceeds 90%, even when the users training the HMMs differ from those executing the task. For a task consisting of both path following and avoidance motions, an HMM-based virtual fixture switches the compliance from low to high when the user is trying to move away from the path. The HMM method improves operator performance in comparison with a constant virtual fixture and no virtual fixture.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.

We relate the capabilities and limitations of the device to the requirements of our approach and describe a number of developments that result in a successful mix of passive haptics and active force feedback.

The proposed method is a two-step procedure: surface normal smoothing through fuzzy vector median (FVM) filtering followed by integration of surface normals for vertex position update based on the least absolute error (LAE) criteria. The median and Order Statistic based filters are extensively used in signal processing, especially image processing due to their ability to reject outliers and preserve features such as edges and monotonic regions. More recently, fuzzy ordering theory has been introduced to allow averaging amongst similarly valued samples. This paper extends the fuzzy ordering concept to vector based data and introduces the fuzzy vector median filter The application of FVM filters to surface normal smoothing yields improved results over previously introduced normal smoothing algorithms. The improved filtering results, coupled with LAE vertex position update, produces surface smoothing that minimizes the effects of noise while simultaneously preserving detail features. Simulation results are presented showing the performance of the proposed method and its advantages over commonly used surface smoothing algorithms. Additionally, optimization procedures for FVM are derived and evaluated.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.

The purpose of this research was to examine human visuo-motor behavior when visual and haptic feedback displays are integrated. A Fitts' Law paradigm involving a target acquisition task was used. Performance measures included movement time to complete the task as well as movement kinematics and kinetics. The variables manipulated included two target widths, two target amplitudes, and six haptic emulations. Damping forces over target areas result in the best performance. Spring forces over target areas resulted in the worse overall performance. Haptic emulations were found to be most effective as the Index of Difficulty increased. Motor planning changed as a function of the haptic emulation used. The implication of these findings is that the effectiveness of the HCI design is greatly influenced by haptics.","PeriodicalId":177962,"journal":{"name":"11th Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2003.
