The present disclosure provides a collision judgment method and apparatus. The method includes: determining, by a moving device, according to acceleration data collected by an acceleration sensor, that the moving device collides; sending collision information to the corresponding control device, including at least a moving device identifier and a collision time; sending, by the corresponding control device, the collision information to a collision judgment device; detecting, by the collision judgement device, whether at least two collision information sent by the at least two control devices is received within a predetermined time interval; when the at least two collision information is received within the predetermined time interval, and a difference between collision times carried in the at least two collision information is less than a preset threshold, determining that moving devices corresponding to moving device identifiers carried in the at least two collision information collided with one other.

A method for displaying information of a physical game participant includes obtaining information of the physical game participant and controlling an LED light-emitting device to generate a corresponding lighting form based on the information.

A device for simulating shooting recoil force includes a main body, a cannon barrel, an elastic restoration device, and a driving device. An installation chamber is defined in the main body. An installation blocking plate is provided inside the installation chamber. The cannon barrel is movably arranged within the installation chamber. The cannon barrel includes a hollow cannon rod and a push rod. The push rod is positioned within the cannon rod. The push rod is slidable within the cannon rod. The cannon rod is provided with a first firing port. A first end of the elastic restoration device is connected to the push rod. A second end of the elastic restoration device abuts against the installation blocking plate. The driving device is connected to the push rod for transmission. The driving device is used for pushing the push rod towards a direction of the installation blocking plate.
