Abstract
Graphical user interface (GUI) is designed as the interaction medium between the user and the interface, and the perceptual experience of GUI design has been paid more and more attention by users. Based on the theory of perceptual engineering (KE), two groups of different visual style interfaces were taken as an example to record the EEG data when users watched two groups of visual interfaces, in order to explore the user’s perceptual imagery and perceptual experience for the visual interface. It aims to meet the user’s perceptual needs and provide an effective evaluation method and design basis for the graphical user interface design. Firstly, the EEG spectrogram and brain topographic maps were obtained by data analysis and processing. The results showed that the activity levels of the θ wave and α wave induced by the two groups of different visual style interfaces were significantly different. Secondly, this paper analyzed the user’s perceptual imagery with GUI perceptual design elements, and concluded that the perceptual design elements of GUI would affect the user’s cognitive interest and perceptual experience. GUI design should focus on the unity and coordination of perceptual design elements and perceptual imageries. Finally, it is concluded that the EEG-based perceptual design evaluation method can effectively evaluate the GUI visual interface.
Highlights
From the first application of Graphical user interface (GUI) on a computer in 1973 to the era of digital image reading, users are paying more and more attention to the emotional experience brought by the GUI
The cognitive efficiency and perceptual experience of reading information are often measured by users' subjective questionnaires and behavioral performance methods, while it has been less studied that the theory of KE and neurodesign methods are used to analyze the user's cognitive status and perceptual experience of interface information
In the design of industrial products, emphasis is placed on the feeling of the material texture to the users, and the GUI design emphasizes that the texture awakens and guides the user's emotions
Summary
From the first application of GUI on a computer in 1973 to the era of digital image reading, users are paying more and more attention to the emotional experience brought by the GUI. As an interaction medium between the user and the product, the goal of the GUI design is to improve the user's cognitive efficiency of information and the user's perceptual experience of the interface. Perceptual design uses materials, shapes, colors, textures and other design elements to guide users to inspire recognition and resonate in the process of knowing the product, so as to obtain pleasure of using product and emotional satisfaction[6]. Among the visual elements that affect perceptual design of the GUI, color is the most direct perceptual design element, which is a more powerful way of expressing information and emotional arousal[12]. Using colors that matches the user's mental model, which can efficiently convey information and can improve user experience and satisfaction.
