Abstract: With the development of information processes, the interaction between humans and computers is everywhere in our daily life. As the level of human-computer interaction continues to rise, the cognitive load in human-computer interaction is also increasing, and thus, the operational error rate is rising. Subliminal communication technology refers to the use of appropriate methods to provide subliminal cues to convey supplementary information in an unconscious way. This method does not increase the burden on cognitive channels, but it improves people's abilities to recognise and make decisions. Therefore, we conducted a series of experiments on the subliminal priming effect to observe the feasibility of this idea. We used experimental psychophysical methods to demonstrate that the subliminal stimuli had a considerable impact on various cognitive processes and decision-making.

Keywords: subliminal priming effect; human-computer interaction; free decision-making; stimulus-driven decision-making.
