[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example 1

[0033] A magic wand includes a magic wand body, wherein the magic wand body is provided with a main control module, and an infrared sensor module, a communication module, an RGB module, a sound sensor module, a motion processing module and a vibration motor module electrically connected to the main control module respectively. The main control module includes a single-chip microcomputer chip U3 with the model number of STM32F103C8T6.

[0034] The infrared sensor module is used to detect the object pointed by the magic wand. When the magic wand points to an obstacle, it can trigger a specific magic effect or feedback, such as lighting an LED or starting other functions, so that the magic wand can sense the surrounding environment. This adds interactivity to the magic wand of this embodiment, similar to the magic detection function.

[0035] By connecting to a mobile phone or other smart device via a Bluetooth module, users can control the magic wand's functions or receive the magic wand's status information through the mobile device. For example, they can remotely set magic effects through the mobile phone APP or receive the magic wand's sensing data, which increases remote control and customizability.

[0036] By connecting the Magic Wand to the Internet through the WIFI module, longer-distance control and interaction can be achieved. That is, the function expansion can be achieved through the server platform. For example, the Magic Wand can obtain specific magic instructions from the server or trigger preset effects, which brings higher intelligence and networking features to the Magic Wand.

[0037] The RGB module provides color-changing lighting effects, showing different magic through different colors and flashing modes. Users can trigger different lighting effects based on gestures, sounds, or obstacle sensing, enhancing the visual expression of the magic experience;

[0038] The sound sensor module is used to detect surrounding sounds. When it detects specific sounds such as clapping or shouting, it triggers magic effects, such as lighting up the magic wand's light or activating vibration feedback. This makes the magic wand voice-activated and can respond to user voice commands, enhancing the interactive experience.

[0039] The motion processing module senses the magic wand's posture and movement to identify the user's waving gestures. Combined with accelerometer and gyroscope data, the magic wand can determine the user's waving direction, speed, and other information, and then trigger the corresponding magic effect. This allows the magic wand to recognize different waving gestures and perform different magic.

[0040] The vibration motor module is used to provide tactile feedback. When certain magic effects are triggered, the magic wand will vibrate, giving the user a real sense of feedback. For example, when a magic spell is successfully cast, the magic wand will vibrate to enhance the experience and make the user feel that they are actually casting a spell.
