Paper Abstract:
|
Interpretation of ambiguous images perceived visually and relying on supplementary information coordinated with pictorial cues was selected to evaluate the usefulness of the StickGrip device. The ambiguous visual models were achromatic images composed from only two overlapping ellipses with various brightness gradients and relative position of the components. Inspection of images by the tablet pen enhanced with the pencil-like visual pointer decreased discrepancy between their actual interpretation and expected decision by only about 2.6 for concave and by about 1.3 for convex models. Interpretation of the convex images ambiguous with their inverted concave counterparts inspected by the StickGrip device achieved three times less discrepancy between decisions made and expected. Interpretation of the concave images versus inverted convex counterparts was five times more accurate with the use of the StickGrip device. We conclude that the kinesthetic and proprioceptive cues delivered by the StickGrip device had a positive influence on the decision-making under ambiguous conditions. |
