Exhibition Guide System Using Location and Orientation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing exhibition guides, such as brochures or human-guided tours, are inconvenient and limited by the need for physical presence and availability of equipment, especially in crowded or distant locations.
Innovation Solution
An electronic device equipped with GPS, electronic compass, and network connectivity that detects user location and orientation, selects nearby exhibits, and plays corresponding commentary on a display screen, allowing for an efficient and accessible exhibition guide system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speech ciphering equipment is provided at the exhibition, then users can obtain information, but the quantity of equipment is limited and users may not be able to rent it
Solution Approach 1:
The patent applies universality by enabling ordinary mobile phones to function as exhibition guide devices through wireless communication. Instead of requiring specialized speech ciphering equipment, any mobile phone with wireless capability can receive and display exhibition information, thereby multiplying the available guide capacity without needing to increase the number of dedicated guide devices.
Solution Approach 2:
The patent implements copying by transmitting exhibition information digitally from a central server to multiple user mobile phones simultaneously. This allows unlimited replication of guide information without physical constraints, enabling many users to access the same exhibition content without requiring proportional increases in physical guide equipment.
2Reliability
If human guides or speech ciphering equipment are used, then users can receive guidance, but users must visit at a specific time when the guide is available
Solution Approach 1:
The patent implements self-service by enabling users to independently access exhibition information through their own mobile phones without requiring human guides or scheduled appointments. Users can autonomously receive, navigate, and interact with exhibition content at any time, eliminating dependency on guide availability and providing complete temporal flexibility.
Solution Approach 2:
The patent introduces a wireless communication system and server as intermediaries between the exhibition content and users. This intermediary infrastructure replaces human guides, allowing information to be transmitted automatically to any user at any time, thereby decoupling guide availability from user visit timing.
3Reliability
If speech ciphering equipment is used in crowded exhibitions, then users can hear guidance, but users distant from the guide or in crowded areas have difficulty hearing
Solution Approach 1:
The patent replaces the acoustic-based speech ciphering system with an electronic data transmission system. Instead of relying on sound waves that are susceptible to crowd noise and distance attenuation, the system uses wireless electromagnetic signals to transmit exhibition information directly to mobile phones, eliminating the harmful effects of acoustic interference entirely.
4Ease of operation
If brochures or catalogs are provided, then users can read information, but users must physically carry and access them
Solution Approach 1:
The patent applies copying by replacing physical brochures and catalogs with digital versions transmitted wirelessly to mobile phones. Users access exhibition information in electronic form without needing to physically carry paper materials, thereby simplifying the user experience while eliminating physical constraints.

AI summary
A method provides an exhibition guide using an electronic device. The method obtains exhibit information of a plurality of exhibits in a preselected exhibition from a remote computer, obtains location coordinates of the electronic device, calculates a distance between each exhibit and the electronic device, and determines one or more exhibits which are adjacent to the electronic device. The method further obtains an indicating direction of the electronic device, compares the indicating direction of the electronic device with a display direction of each adjacent exhibit to obtain a matched exhibit, and plays commentary of the matched exhibit on the electronic device.
