A Novel Haptic Sensor-Actuator System for Applications in Virtual Reality
نویسندگان
چکیده
A novel system for the generation and representation of haptic information in virtual reality is described. With this system the stiffness distribution of mechanically inhomogeneous objects can be detected and made perceivable for users at distant locations. The sensor part is based on ultrasonic elastography and the actuator part utilizes the ability of electrorheological fluids to change their consistency in electric fields reversibly. Two-dimensional elastographic images or arbitrary projections of three-dimensional objects generated in the sensor part can be represented by the actuator part, which has a flat surface above a two-dimensional array of actuator elements with individually addressable stiffness. Due to the lack of established technologies, several innovative technological approaches have been introduced for the development of the haptic system. The haptic sensor-actuator system can serve as a technology platform for the subsequent development of new products in various fields of applications such as medicine, entertainment or education.

Mechanical properties of biological tissue represent important diagnostic information and are of histological relevance (hard lesions, "nodes" in organs: tumors; calcifications in vessels: arteriosclerosis). The problem is, that such information is usually obtained by digital palpation only, which is limited with respect to sensitivity. It requires intuitive assessment and does not allow quanti...
