Abstract

Disclosed is a die with electrophoretic ink or a liquid crystal display (LCD) on each side that uses radio frequency identification (RFID) communication with a play mat or pinhole button to set the dice to predetermined settings, changing the sides of the die as needed to match the game being played.

Electronic Dice with changing faces via RFID Mat

Many board and role-playing games require the use of dice with many different shapes, sizes, face counts, and symbols. This is can be inconvenient for people who are bringing dice for multiple games to different locations; one set is not applicable for all game play.

The novel solution is a die (or set of dice) with electrophoretic ink or a liquid crystal display (LCD) on each side that can be controlled via different methods to change the images/symbols based on the current game in play. This system is applicable to any multi-sided die (e.g., six to 20 sides).

One method is to use radio frequency identification (RFID) communication with a play mat to set the dice to predetermined settings, changing the sides of the die as needed to match the game being played. The sides are controlled by an internal Application-Specific Integrated Circuit (ASIC) attached to an RFID reading device. A special game mat has a side portion divided into sections. (Figure 1) To change the sides of the die, the player places the die in the desired numerical location. The RFID device in the die reads the implanted RFID device in the mat and sends the desired configuration information to the ASIC. The ASIC then changes the facings on the die.

An alternate method of changing facets is a small pinhole in one of the facets that allows the player to make a selection through a set order of configura...
