Abstract:
|
The sine illusion, which is part of a set of optical illusions which occur based on a conflict between a stimuli and the real-world situation which can cause similar stimuli, has a notable impact on perception of time-series data with a seasonal component. In this paper, we discuss the reasons for the illusion and various strategies which might be useful to break the illusion or reduce its' strength, demonstrating the presence of the illusion in real-world and theoretical situations. We also present data from user studies which demonstrate the dramatic effect the sine illusion can have on conclusions drawn from displayed data.
