Description

Technical Field

[0001] This invention relates to the field of intelligent tour guide technology for museums and exhibition venues, and in particular to a system and method for enabling self-guided explanations of exhibits using the NFC function of a mobile phone and a WeChat mini-program. Background Technology

[0002] With the rise in cultural consumption, the number of visitors to museums and exhibition venues is increasing daily. Traditional guided tours and rental audio guides can no longer meet the diverse and personalized needs of visitors. Existing technologies have the following shortcomings:

[0003] Specialized equipment needs to be rented, which is costly, difficult to maintain, and puts great pressure on epidemic prevention.

[0004] The QR code solution requires viewers to actively scan the code, which is cumbersome and prone to failure due to lighting or angle issues.

[0005] Traditional app solutions require prior download and installation, making them difficult to promote.

[0006] It cannot be integrated with social media platforms, making it difficult to achieve secondary dissemination;

[0007] There is a lack of systematic means to collect and analyze audience behavior data.

[0008] Therefore, there is an urgent need for a low-cost, zero-learning, easy-to-deploy, and operable self-guided tour solution. Summary of the Invention

[0009] The purpose of this invention is to provide a self-guided tour system and method based on mobile phone NFC, so as to overcome the defects of the prior art.

[0010] The core concept of this invention is to leverage the high penetration rate of the WeChat ecosystem, the instant accessibility of mini-programs, and the seamless interaction via NFC on mobile phones to write exhibit codes into NFC tags. Users can retrieve and present multimedia tour content within the WeChat mini-program simply by bringing their mobile phones close to the tags, and continuously iterate the content and operations through the cloud.

[0011] Beneficial effects

[0012] Viewers do not need to install a new app; they can simply touch their phone to the chip to access the mini-program and use it. NFC near-field communication is highly resistant to interference, has a fast response time, and does not require focusing, providing a better experience than QR codes.

[0013] It supports a mixed offline and online mode, and can still be accessed normally even in the event of a network failure;

[0014] Supports immersive experiences such as AR / VR, enhancing the attractiveness of exhibitions;

[0015] Automatically generates user profiles and museum data reports, facilitating refined operations;

[0016] The deployment cost is low, requiring only NFC tags and cloud services, without the need to modify the exhibition hall's low-voltage electrical system. Attached Figure Description

[0019] Figure 3 User-side interaction flowchart Detailed Implementation

[0020] Example 1 (Museum Painting Exhibition)

[0021] NFC tag: Uses NTAG 21 series tags, with 7 bytes of UID and 4 bytes of custom exhibit ID written in;

[0022] Mobile Phone: iPhone 11 or above or Android 9.0 or above, with NFC enabled; Mini Program: Upload the "eTouch" code via WeChat Developer Tools, and configure the business domain name and CDN;

[0023] Cloud: Deployed on Alibaba Cloud ECS, using OSS+CDN to distribute 1080p videos and 3D models;

[0024] Interaction: Viewers tap their phones against the NFC tag in the lower right corner of the painting frame → a 60-second HD video of the painting plus an AR animation of the artist's life pops up in the mini-program → viewers like the video and share it to their WeChat Moments with one click → the background records the duration for 90 seconds.

[0025] Example 2 (Interactive exhibits at the Media Museum)

[0026] NFC tag: Uses NTAG 21 series tags, with 7 bytes of UID and 4 bytes of custom exhibit ID written in;

[0027] Mobile Phone: iPhone 11 or above or Android 9.0 or above, with NFC enabled; Mini Program: Upload the "eTouch" code via WeChat Developer Tools, and configure the business domain name and CDN;

[0028] Cloud: Deployed on Alibaba Cloud ECS, using OSS+CDN to distribute 1080p videos and 3D models;

[0029] Interaction: Visitors tap their phones against the NFC tag on the front of the exhibit's protective glass cover → A mini-program pops up a 60-second high-definition video and AR animation of the exhibit → Visitors can swipe their phone screens to view the exhibit from various angles (VR) → Visitors can like the video and share it to their WeChat Moments with one click → The system records the duration of the 90-second pause.
