SYSTEM, METHOD AND APPARATUS FOR DISPLAYING A NON-BIASING AND SELF-ADJUSTING VISUAL ANALOG SCALE ON A COMPUTING DEVICE

摘要

A system and method for displaying a non-biasing VAS that automatically adjusts to different screen aspect ratios resolutions of a computing device, while preserving the reliability of the VAS. The system and method can calculate a number of pixels available on a screen display to display a VAS. Further, the system and method can generate a VAS comprising equally sized intervals of distance to fit the available screen display. In addition, the system and method can include an anchor line at each end of the VAS that indicates an upper and lower value of a range of values measured by the VAS. The system and method can also include a unit cursor on the VAS that allows a subject to indicate, by pixel, interval or target area, a position on the VAS.
