Voice Server Item Information Delivery via RFID Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient and cost-effective method to deliver item-specific information to users, particularly for visually impaired individuals, using voice servers and RFID/barcode scanning technology, as they require extensive storage and local text-to-speech generation, which is costly and inflexible.
Innovation Solution
A device that scans unique identification codes using RFID or barcode scanners, connecting to a voice server to retrieve and convert non-audible information into audible format, utilizing a text-to-speech voice server for flexible and secure delivery of item-specific information, reducing the need for local storage and enhancing user experience with high-quality voice generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local text-to-speech generation is used, then item-specific information can be delivered, but storage requirements and system cost increase significantly
Solution Approach 1:
The patent extracts the text-to-speech generation function from the local device and relocates it to a remote voice server. The mobile device only stores minimal identification data (RFID/barcode), while the voice server stores and processes all item information. This extraction eliminates the need for large local storage capacities while maintaining reliable information delivery.
Solution Approach 2:
The patent introduces a voice server as an intermediary between the mobile device and the information database. The mobile device scans the item code, sends the request to the voice server, and receives audible information from the server. This intermediary handles the complex storage and processing functions remotely, reducing local device requirements.
2Loss of information
If extensive local storage is implemented, then item information can be stored, but device complexity and cost increase
Solution Approach 1:
The patent removes the complex information storage and processing subsystem from the mobile device. Only the scanning function and basic communication remain on the device, while the voice server handles all information management. This extraction significantly reduces device complexity while maintaining information accessibility.
Solution Approach 2:
The voice server provides universal access to item information for any mobile device with scanning capability. Instead of each device needing its own database and processing system, a single centralized server serves multiple devices, reducing overall system complexity and cost.
3Adaptability or versatility
If voice server connection is used, then flexible and secure information delivery is achieved, but connection requirements are added
Solution Approach 1:
The voice server acts as an intermediary that standardizes the connection interface. Mobile devices with various scanning capabilities (RFID, barcode) can all connect to the same voice server through standard communication protocols. This intermediary layer provides flexibility in information delivery while managing connection requirements centrally.
Solution Approach 2:
Instead of storing complete information locally, the system creates a lightweight copy of the identification data (RFID/barcode) on the mobile device and retrieves the full information from the voice server. This copying approach enables flexible information delivery without requiring complex local storage and processing capabilities.
Data Source
AI summary
A device for accurately and flexibly delivering item-specific information from a voice server to a user and the method of using same is disclosed. The user scans a unique identification code associated with an item using a scanner on the device. The device then connects to the voice server. The voice server searches for information related to the item and converts the information for the item into audible information for delivery to the user. The audible information is audibly played to the user by the device.
