A computer-readable tangible non-transitory storage medium storing a program for causing a terminal of a viewer to: receive, from a server over a network, a video data related to a live-stream in which a distributor, the viewer, and other viewers participate; accept input of normal information by the viewer during the live-stream, the normal information being viewable by the distributor and the other viewers; and accept input of exclusive information by the viewer during the live-stream, the exclusive information being information that is transmitted to a terminal of the distributor on condition that the viewer pays or consents to pay a price and that is not viewable by the other viewers.

This invention relates to a crystal ball for emotional interaction, featuring a touch-sensitive surface, a lighting system, a vibration mechanism, and a wireless communication module. When a user interacts with the touch-sensitive surface, the control system generates synchronized light and vibration outputs that are transmitted to a paired crystal ball, allowing for real-time emotional communication between remote users. The lighting system creates dynamic visual effects, including expanding or shrinking halos across the spherical surface, representing different emotional states. This system offers a tangible and immersive means of emotional expression, blending modern technology with the symbolic essence of traditional crystal balls.
