Modern people are facing increasingly serious mental health problems under the COVID-19 pandemic. Biofeedback training, as a powerful self-regulation method for stress management and relaxation training, is in need of improvement and optimization in digital era. With the aim of promoting the integration and development of biofeedback training and virtual reality, and improving users’ motivation as well as engagement in biofeedback training, we come up with a novel construction method of integrating virtual reality and biofeedback training system based on psychoengineering paradigm. The method can be applied to various categories of biofeedback training including heart rate biofeedback, breath training biofeedback, stress intervention biofeedback and so on. Results of the research demonstrate that the construction principle can promote the integration and development of virtual reality and biofeedback training, and have the potential to improve user’s motivation as well as engagement of biofeedback training.
Visual symbols are the main component of visual design. Professor Wei Huang proposed the eye-opening theory of visual symbols in 1995 and pointed out the effect of changes to the whole. Based on the principle of visual closure in Gestalt psychology, for a figure with missing part, the human perceptual impressions will subject it to subjective processing, either to complement the missing part or to separate it from the whole. However, what is the most noticeable missing ratio that can cause visual retention? This paper will use the classic point detection paradigm of psychology to design experiments to measure the eye-opening perception of visual symbols.
