Abstract

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.

Claims

19. A system for displaying a visual analog scale comprising:

a screen display;

one or more computer processors; and

non-transitory computer-readable medium comprising instructions operable, when executed by the one or more computer processors, cause the system to;

generate the visual analog scale based on a number of pixels on the screen display, wherein the visual analog scale comprises equal intervals of distance to fit the number of pixels.

20. The system of claim 19, wherein the visual analog scale is displayed on the screen display in a vertical orientation or a horizontal orientation.

21. The system of claim 19, wherein the instructions, when executed by the one or more computer processors, further cause the system to generate target areas on the visual analog scale.

22. The system of claim 21, wherein each target area of the target areas is equally sized.

23. The system of claim 21, wherein each target area of the target areas corresponds to a value on the visual analog scale.
