Vision is an indispensable source for people to receive graphic art. However, human eyes often have illusions. The various effects of these visual illusions often surprise the viewers, and because of that, we have created many creation and design by using these visual illusions, Moiré Effect is one of the techniques that are often being used, it can create dynamic effects in static images, adding richness to the design.
This research will be discussing the influence of how the change of the grid affects Moiré effect. The grid is one of the key elements of the dynamic effect, and directly affects the conditions of the base Graphics. It impacts of dynamic effects significantly. Now a day, many of these researches and creations are more focus on the Physical art form, so in this study, it will focus on discussing the usage of digital media and experiment on the topic.
In order to more directly record the impact of grid changes, this study will use the "experimental research method" and is divided into three stages.
The first stage will be related to the classification of relevant literature, and organize support theory for the research. In the second stage, the experiment would be actually carried out. Three sets of experiments were carried out under different changes of the grid, in following order: "Experiment of grid spacing ratio change", "equal scaling experiment under fixed grid ratio" and "different grid moving mode". Each group of experiments was divided into two groups, which will be "rotation movement " and “parallel movement”. The test subjects were 30 different people with normal vision, and half of them had art related major background, other half does not.The films for the experiment each were 600 frame and 20 second long. Finally, on the third stage will be to summarize the experimental results, analyzes the conclusions and recommendations for future use.
By the results of the experiment data, it found that the viewer has a different demand for dynamic performance according to the type of the base image. For example, on the rotation pattern, when the movement is large and obvious, the response is better, but when it comes to the parallel movement, swinging dynamics not only need to be obvious, the fluency is also being considered.
In addition, in the overall data display, that the dynamic performance is generally poor when the base layer number is too small. And when the base layer produces a crushing sensation, it affects the dynamic obviously. Furthermore, under the same grid ratio, the lateral grid movement resolution is not as good.
