It is a reference book for the basics of haptic interaction and existing haptic systems and methods as well as an excellent source of information for technical questions arising in the design process of systems and components. Towards this end, a combined physical and psychophysical experimental methodology is presented. Towards this end, we have proposed a combined physical and psychophysical experimental methodology. Towards this end, a combined physical and psychophysical experimental methodology is proposed in this work. The root cause for this shortcoming is absence of theoretical analysis of virtual environment haptic robotic systems. It is based on the Seventh International Symposium on Robotics Research held in Germany on October, 21 - 24th, 1995.
There has been considerable amount of research on the haptic technology, which brought it into computer games, surgical simulators, mobile phones etc. Although there is a variety of task specific evaluation approaches for haptic interfaces, it has not yet been possible to define a norm for meaningful device comparison and assessment. The E-mail message field is required. All orders get full access to our online order status tracking service, allowing you to view realtime order progress. To provide the necessary patient-robot interaction for the assessment and training of the hand throughout the different phases of recovery, high-fidelity haptic interfaces with a wide impedance width Z-width are required.
A haptic system realizes this feedback. Haptics technology is being used more and more in different applications, such as in computer games for increased immersion, in surgical simulators to create a realistic environment for training of surgeons, in surgical robotics due to safety issues and in mobile phones to provide feedback from user action. The psychophysical experiments are unified as a systematic and complete evaluation method for haptic interfaces. A proper evaluation procedure for haptic interfaces should link device performance measures to the limits of human perception in order to obtain device-specific limits. An impedance-based controller with force feedback was implemented to modulate the apparent impedance of the robot's end-effector. Performance Metrics for Haptic Interfaces aims at meeting this need by establishing standard practices for the evaluation of haptic interfaces and by identifying significant performance metrics.
Divided into two parts, part 1 contains typical application areas of haptic systems and a thorough analysis of haptics as an interaction modality. First, the existing physical performance measures and device characterization techniques were investigated and described in an illustrative way. With the proposed control strategy the ReHap-ticKnob shows similar transparent behavior as a Phantom Premium 1. The physical characterization methods were demonstrated on a novel haptic interface for surgical simulation which has been developed in our lab. Secondly, a wide range of human psychophysical experiments are reviewed and the appropriate ones are applied to haptic interactions. Chapters on haptic interaction, system structures and design methodology were rewritten from scratch to include further basic principles and recent findings. For these projects, students received additional hardware, including force sensors, electrooptical encoders or high-performance data acquisition cards.
First, the existing physical performance measures and device characterization techniques were investigated and described in an illustrative way. While a haptic device may come with specifications for its mechanical and electrical properties, no clear relationship between these properties and application-specific performance is available from neither commercial nor academic literature. Further chapters examine interfaces and software development for virtual reality simulations. Arianna permits to navigate colored paths painted or sticked on the floor revealing their directions through vibrational feedback on commercial smartphones. Finally, synthesis of both evaluation methods is discussed.
The psychophysical experiments are unified as a systematic and complete evaluation method for haptic interfaces. The papers were written by specialists in the field from the United States, Europe, Japan, Australia and Canada. Haptic refers to feedback of a physical signal to a human user through touch. It is a flexible and low cost navigation system for vi- sually impaired people. Then, haptic interface evaluation studies in the literature are discussed and categorized into two groups: physical and psychophysical evaluation studies.
The psychophysical experiments were unified as a systematic and complete evaluation method for haptic interfaces. First, the physical performance measures and device characterization techniques were investigated. The metrics reveal the basic characteristics of the devices which are not easily derived from the given specifications. The metrics provided in this state-of-the-art volume will guide readers in evaluating the performance of any haptic interface. Synthesis of Evaluation Methods -- Conclusion.
Experimental user studies were carried out and applicability of the tests to a tactile feedback device was investigated. In this chapter, the physical evaluation methods described in Chap. The metrics provided in this state-of-the-art volume will guide readers in evaluating the performance of any haptic interface. Both aspects are relevant to the formal description of the purpose of a haptic system and the derivation of requirements, which are further explained in Chap. We do not have product details beyond that contained within this listing. Since the whole physical evaluation methodology is very extensive and often requires special equipment, only some methods that are necessary to characterize the haptic interface are discussed here.
In most of the applications today, the physical signal refers to force but not necessary. A commercial system Phantom Omni was taken as a case system to facilitate this research. The metrics provided in this state-of-the-art volume will guide readers in evaluating the performance of any haptic interface. Finally, synthesis of both evaluation methods is discussed. Firstly, existing physical performance measures and device characterization techniques are investigated and described in an illustrative way. The existence of these applications highlights a clear need to understand performance metrics for haptic interfaces and their implications on device design, use and application.
