A benchmark test system captures and records root, or input, behavior from a user input device as one or more time-displaced samples of input. The system also separately captures and records the canvas, or visual, behavior of a user interface in response to the captured input as a series of time-displaced image frames. The image frames are analyzed for visual prompts occurring responsive to the input, and parameters of the image frames are determined. A parametric difference between corresponding ones of the root events and canvas responses is thereby computed, in order to determine a degree of visual responsiveness for the user interface software respective to the root input.

A method for using simulated physics to animate slot symbol objects of a slot video game is disclosed. The method goes beyond the visual concept of reels spinning up or down by applying physics calculations to video slot symbol objects, resulting in new animated behavior of the video slot symbol objects outside of the constraints of a reel boundary or a pattern.
