Computerized Mind-Reading Magic Trick with Remote Transmission

Magic is typically presented live, and computer presentation is relatively rare. This article is based on mind-reading magic and presents the magic process on a computer. Twenty-one cards are given to the spectator to make choices. Through the processes of dealing, collecting and questioning, the playing cards considered are transformed through mathematical derivation. This article uses the tree table lookup method to replace the mathematical algorithm used in the original magic. The program execution results can indeed achieve good results. Finally, we considered only displaying the card that the person was thinking about on the screen, but found this too monotonous and lacking in interactivity. Thus, the magic result will be presented on a touch panel or mobile webpage, so as to set off the final climax at the end of the magic. The playing card suits and numbers generated by the computer are transmitted to the touch panel via Bluetooth. Another method is to use Raspberry Pi to set up a server and create a database form, sending the card suits and numbers to the database form through Wi-Fi. Players can then connect to the IP address through their mobile phones to display the picture of the playing cards.
