From: Design aspects of vaginal applicators that influence acceptance among target users
Comparison of physical dimensions with perceived length and width, as measured on 100 point visual analog scales with indented semantic anchors at 10 (Very short/thin) and 90 (Very long/thick). Panel (a) shows the influence of physical barrel and packaged length on perceived length. Open bars and error bars indicate perceived length on the VAS for length; physical length (in cm) for each applicator is shown as packaged (solid squares) and barrel length (open circles). Notably, the 8 products on the left had similar lengths for barrel length and package length (overlapping circles and squares), and these generally corresponded to the perceived length (open bars). In contrast, the 10 applicators on the right side had substantial differences between packaged length and barrel length. Panel (b) shows how perceived width is influenced by physical dimensions of the insertion end and grip surface. Open bars and error bars indicate perceived width on the VAS; physical width (in cm) are shown for the insertion end (solid squares) and grip surface (open circles). As expected, perceived width was more closely associated with the physical width of the insertion end than the grip surface width. Within in a panel, mean ratings that have a letter in common are not significantly different at α = 0.05 (Fisher’s LSD).
