02 Apr 1997TL;DR: This paper discusses the development of a new approach or method for the off-line programming of robotic devices, indicating some of the potential applications, and highlighting some the restricting limitations that need to be overcome.
Abstract: Virtual reality (VR) is an evolving technology being adopted by manufacturing in areas (such as operator training, and the virtual testing of new products before manufacture), where it is now becoming a widely accepted industrial tool. Of particular note are applications in off-line programming of robots. However, before this concept finds acceptance in industry, countless problems need to be resolved. Several problems are addressed within this paper, including the requirement of an acceptable interaction device, and the subject of haptic and tactile feedback. As manufacturing continually moves to become a more responsive environment, with products having shorter life cycles and batch quantities reducing in size, robot programming times become critical, and hence an area to be addressed in order to seek improved productivity. Off-line programming is one approach, where for example off-line programming within a virtual environment could reduce the required skill levels of a programmer, reduce the programming times, allow the operator a `natural' interface with which the operator would conduct the task in the real world, and reduce the boredom factor. This paper discusses the development of a new approach or method for the off-line programming of robotic devices, indicating some of the potential applications, and highlighting some of the restricting limitations that need to be overcome. The paper also includes a review of previous published work on the off-line programming of robots using VR.

26 Apr 1999TL;DR: From the extensive experience with design- ing haptic computer user interfaces and using haptic interfaces in the real world, certain qualities of haptics are abstracted and used in the analysis and design of a suite of 3D haptic widgets.
Abstract: D interaction with a computer is hard. As human interaction in the real world is quite dependent on haptics, we believe that adding haptics will alleviate many of the problems of 3D interaction with a computer. The naive approach to incorporating haptics would be to simply find existing objects and imitate them. This, however, would not seem to adequately leverage what is possible with a rea- sonably general force feedback device, as it does not take advantage of the ability to provide forces that are not physically based, or to simulate objects and behavior that could have been physically real- ized but weren't, or which would have been prohibitively difficult to physically realize. From our extensive experience with design- ing haptic computer user interfaces and using haptic interfaces in the real world we have abstracted from those interactions certain qualities which we present in this paper. In addition, this paper demonstrates how to use these qualities in the analysis and design of a suite of 3D haptic widgets, most of which are novel and many of which include non-physically based forces.

TL;DR: How to extend human perception beyond differential thresholds and thus enhance sensitivity is described, which shows that the operator is able to discriminate tinier differences using a telemanipulation system with enhanced sensitivity than through direct manipulation.
Abstract: Haptic feedback is one of the missing links in robotized minimally invasive telesurgery. The teleoperation controllers are optimized so as to offer the surgeon a reliable perception of the stiffness of soft tissue, rather than following the traditional approach where tracking and force reflection fidelity are considered. The experimental results show that optimization allows for better focus on the quality of the haptic information in the performance-stability trade-off. A force sensor to measure the interaction forces with the environment is found to be indispensable for high-quality touch feedback. Next to optimization for realistic feedback of the environment stiffness, in this paper we describe how to extend human perception beyond differential thresholds and thus enhance sensitivity. Experiments on a one-dimensional system demonstrate that the operator is able to discriminate tinier differences using a telemanipulation system with enhanced sensitivity than through direct manipulation.

07 May 2016TL;DR: Several novel haptic interactions for the Haptic Edge Display are described including dynamic physical affordances, shape display, non-dominant hand interactions, and also in-pocket ``pull' style haptic notifications.
Abstract: Current mobile devices do not leverage the rich haptic channel of information that our hands can sense, and instead focus primarily on touch based graphical interfaces. Our goal is to enrich the user experience of these devices through bi-directional haptic and tactile interactions (display and control) around the edge of hand-held devices. We propose a novel type of haptic interface, a Haptic Edge Display, consisting of actuated pins on the side of a display, to form a linear array of tactile pixels (taxels). These taxels are implemented using small piezoelectric actuators, which can be made cheaply and have ideal characteristics for mobile devices. We developed two prototype Haptic Edge Displays, one with 24 actuated pins (3.75mm in pitch) and a second with 40 pins (2.5mm in pitch). This paper describes several novel haptic interactions for the Haptic Edge Display including dynamic physical affordances, shape display, non-dominant hand interactions, and also in-pocket ``pull' style haptic notifications. In a laboratory experiment we investigated the limits of human perception for Haptic Edge Displays, measuring the just-noticeable difference for pin width and height changes for both in-hand and simulated in-pocket conditions.

25 Mar 2010TL;DR: A prototype system that provides kinesthetic Feedback to the arm and tactile feedback to the fingers is implemented, the difference of weight recognition according to the applied point of kinesthetic feedback, and the effectiveness of the proposed method are confirmed.
Abstract: For designing a simple and more realistic haptic feedback system, we propose integrating an underactuated mechanism with one-point kinesthetic feedback from the arm with multipoint tactile feedback. By focusing on the division of roles between the cutaneous sensation in fingers and the proprioception in the arm. We have implemented a prototype system that provides kinesthetic feedback to the arm and tactile feedback to the fingers, examined the difference of weight recognition according to the applied point of kinesthetic feedback, and confirmed the effectiveness of the proposed method.
