Self-Instructional Training Interface Using a Speech Bubble That Facilitates Users to Internalize the Automatically Generated Texts

Interactive systems that enable people to easily access mental health care in their daily lives are being studied. Self-instruction training, which is a kind of cognitive-behavioral therapy, is expected to be effective for general-purpose mental health care, but the difficulty for users to create self-instructional texts by themselves has hindered its widespread use. Furthermore, it is not sufficient to simply use a computer-assisted method for the training in which the computer automatically generates the self-instructional texts. This is because previous studies have shown that users do not feel self-instructional texts that are not created by themselves are their thoughts, and consequently cannot internalize the content of the texts, reducing the effectiveness of the training. In this study, we focused on the interface design that facilitates users to internalize automatically generated self-instructional texts, toward the realization of a self-instructional training support system. We proposed an interface that shows the real-time captured video of a user's face like a mirror and superimposes a speech bubble containing a self-instructional text to be connected to the user's face and confirmed the interface facilitates the user's internalization of the text through online experiments. The contribution of this paper is to provide a novel interface design for computer-assisted self-instructional training.
