I'd like to set up an experiment where lines are drawn, of varying lengths and duration, from left to right across the midpoint of the screen. I have two conditions, one where the lines are drawn at a constant draw rate (approx 0.167 pixels per millisecond) and the other where the following lengths and durations are fully crossed to give a variable draw rate:
Length (px) Duration (ms)
The participants task is to estimate the duration of the line.
Is it possible to set this up in OS (I'm using version 3.0.7) to give accurate lengths and durations as well as a smooth animation?
