Mechanical calibration of MouseMove.
(a) Video still image of a mouse-like object affixed to a perspex arm driven by a speed-controlled rotor. The clockwise rotation of the arm is indicated. The position of the mouse-like object was varied (n = 3 positions) to produce a slow, intermediate and fast circling object for tracking. (b) The corresponding cumulative x,y coordinates tracked by the preprocessing macro over the 800 s videos. The diameter of the tracked circular path for the mouse-like object is indicated. (c) The tracked x,y coordinates (from panel (b)) were fed into MouseMove’s GUI and the observed measurements (green shading), the expected values (yellow shading) and the percent accuracy between the observed versus expected measurements (blue shading) is shown.
