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.

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.

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.

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.

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.
