LaForge-Mary-C. Knowles-Patricia-A. Stone-Louis-H. TI Improving sales call reporting for better management decisions. SO Journal-of-Consumer-Marketing. Fall, 1992. v9(n4). p65(8). IL table. AB A technique to facilitate sales force feedback and information flow into the marketing information system (MIS) was discussed. The technique requires the involvement of sales personnel in gathering information about the marketing environment and systematically channeling that information into the company's MIS. The technique was applied in the specific case of a food industry company which decided to use call reports as part of sales force feedback gathering mechanism for its MIS. 2 AN 12804113 AU Shandle-Jack. TI Virtual reality needs better sensors. (Technology Briefing) (Column). SO Electronic-Design. Sept 17, 1992. v40(n19). p18(1). AB Virtual reality (VR) is providing fertile ground for engineers. VR still needs an optimum position-sensing technology that uses data from head-mounted position sensors to locate a participant within the x, y, and z axes of virtual space. Current products that deliver accuracy are still too expensive for business or consumer applications. The tactile sensing and force feedback areas of VR also present a variety of opportunities. Better systems for interacting with the virtual world are needed. Improved tactile sensing in gloves are needed; micromachined devices could be the answer. Force-feedback devices are needed that can simulate real objects. VR needs real sensor technology to move beyond the most expensive applications. PT Column 3 AN 12583281 AU Churbuck-David-C. TI Applied reality. (virtual reality becomes an industrial tool) (Computers/Communications). SO Forbes. Sept 14, 1992. v150(n6). p486(4). AB Virtual reality is coming of age in the industrial world as companies, such as VPL Inc, Bechtel and Boeing, design systems for factory controls, experimental aircrafts and construction equipment, among others. Research and experimentation, however, continues in the aspect of tactile control - an area in which virtual reality technology is deficient. A basic virtual reality system manipulates abstract objects via a disembodied hand that floats in space. The movements are then translated into commands that can control the visual display. For more complex applications such as surgery, however, information that can be had from tactile manipulation is essential for precise maneuvers. Virtual reality researchers are experimenting on various approaches to solve such tactile deficiency. One approach uses tactors, or tiny switches created from a 'shape memory' nickel-titanium alloy, that are sensitive to touch. A force feedback joystick being experimented on can mimic an object's texture. 4 AN 12339165 AU Gosch-John. TI Interactive trackball relies on force-feedback sensing. SO Electronic-Design. May 1, 1992. v40(n9). p32(2). IL photograph. AB Researchers at the Institute for Perception Research in Eindhoven, the Netherlands, have designed an innovative trackball cursor control device that greatly reduces user movement and eyestrain via its ease of use and ability to sense resistive force. Unlike traditional input devices that require hand and arm movement, this new trackball is moved using a single finger. Traditional trackballs allow the cursor to move any where on the screen, causing excessive motion and eyestrain, but the new trackball can be programmed to restrict he cursor's movement. If the cursor strays into inappropriate areas, the user feels resistance and is guided back to approved areas. Eye-hand reaction time is about 30 percent less because the direct movement of the cursor by the trackball makes it easier to locate. 5 AN 12010516 AU Holloway-Richard. TI Virtual worlds research today. (University of North Carolina). SO Byte. April, 1992. v17(n4). p180(1). AB A new system under development at the University of North Carolina (UNC) at Chapel Hill will let users 'walk through' virtual scenes with a three-dimensional interface. It combines VPL Research's EyePhone for displaying images, an optoelectronic tracker for monitoring head position and orientation and a massively parallel graphics engine for generating the images displayed on the head-mounted display. Ivan Sutherland first postulated the development of virtual worlds in 1965, and researchers at NASA-Ames, MIT and the University of North Carolina are among those who have developed new technologies to create 'artificial reality' which the user can directly experience. Major technical problems remain; image generation of complex scenes is still difficult at real-time rates, and force feedback has not yet been perfected. UNC researchers are addressing all of these issues.
