| Abstract | or haptic, applications in medicine, engineering, and design are increasing in popularity and importance based on the advantages of haptic devices in providing intuitive and realistic interactions with virtual environments. However, the use of current commercial haptic devices has been compared to interacting with the world using a stick, so the experience these devices provide fall far short of touch sensations encountered in the real world. In particular, current haptic devices lack integrated tactile feedback, which communicates contact and sliding between fingertips and an object. Although a variety of tactile displays have been developed, most are large bench-top devices and are impractical to place at a user's fingertips while exploring a virtual object. Simpler, more compact devices will solve this problem and provide a means to create a more compelling virtual touch experience. The hypothesis of this research is that the addition of a simple tactile display to a standard haptic interface can greatly enhance the dexterous capabilities of these interfaces, and thus, the types of tasks and quality of work that can be accomplished in immersive environments. The overarching objective of this research is to significantly improve the quality of touch feedback obtained with haptic interfaces by improving both the mechanical interface to virtual worlds and the supporting computational methods that generate touch sensations. These advances will be informed by and validated through a progression of human subject experiments that will culminate in two application-based evaluations in the areas of medical bone palpation and virtual assembly. These case studies will quantify the improved dexterous manipulation and exploration capabilities resulting from this research. To accomplish these objectives, the PI has formed an interdisciplinary team with the project's Co-PI and Senior Research Associate to create a series of new hand-mounted tactile displays and the new haptic rendering algorithms required to support the combination of these tactile displays and force feedback devices. To maintain the required small package size, these devices will only provide a limited set of tactile feedback (e.g., making/breaking of contact and the current location of contact), which has been shown to be effective in the PI's prior studies. A primary focus of this study will be on the use of our developed system for shape perception and improved dexterous manipulation capabilities. This work will be guided by psychophysical experiments to understand relevant human perceptual limits in parallel with initial algorithm and device development to ensure a good fit … |
