Most haptic interfaces are designed with a desire to produce simultaneous perception across multiple senses, with haptic behaviors that complement the task at hand. However, software architectures for haptic interfaces often distribute a virtual model and tasks among multiple processes and CPUs. This functional segregation can reduce the quality of haptic experience, by hiding important details...

As more and more haptic rendering algorithms are developed, the need for evaluation and comparison is becoming more pressing. However, evaluating and comparing haptic rendering algorithms presents two challenges. First, haptic systems provide bidirectional communication between humans and the computer. Therefore, the outputs of such systems are highly reliant on human inputs, which are hard to ...

Studies of self-controlled practice have shown benefits when learners controlled feedback schedule, use of assistive devices and task difficulty, with benefits attributed to information processing and motivational advantages of self-control. Although haptic assistance serves as feedback, aids task performance and modifies task difficulty, researchers have yet to explore whether self-control ove...

This paper describes a psychological experiment which was conducted to evaluate the influence of haptic feedback on the perception of self-motion in virtual reality. Participants were asked to estimate the angle of one turn made during a passive visual navigation. Sometimes, during the turn, a haptic feedback was sent to the dominant hand of the participants. This haptic feedback consisted in r...

Haptics technology has received enormous attention to enhance human computer interaction. The last decade has witnessed a rapid progress in haptic application software development due to the fact that the underlying technology has become mature and has opened up novel research areas. In an attempt to organize the path between cause and effect we envision a need for a standard for haptic applica...

Haptic rendering complex objects in virtual environments is computationally intensive. In this paper we start the investigation of a new category of approach to reducing the computation in haptic rendering. Our approach is based on the hypothesis that the accuracy of haptic perception might be limited. Results of the experiments described in this paper suggest that subjects might not be able to...

Haptics provides powerful cues about forces but cannot easily be integrated in all relevant applications, such as education. Pseudohaptic cues, visual information that simulate haptic sensations, have been raised as an alternative. It is, however, largely unknown how (or even if) pseudo-haptic cues are perceived by the haptic sensory modality. In this paper we present an approach that applies t...

This work develops a methodology for building haptic reality-based modeling systems by exploiting the complementary goals of haptic exploration and display. While the generally unstructured nature of haptic exploration makes it diÆcult to develop and control autonomous robotic ngers, simultaneous consideration of exploration and display provides a way to characterize the required sensing, contr...

This paper presents progress in the development of an untethered haptic feedback system for open surgery simulation and training being developed by Energid Technologies. A key innovation in our simulation is an untethered haptic feedback method. In this paper, we describe our approach to developing an effective untethered haptic feedback system, and our current progress. We also present the res...
