Portable Shopping Displays Using Inaudible Tones for User Personalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product displays, such as vending machines and store fixtures, often have static product selections that do not align with user preferences, requiring users to visit specific locations and limiting access to region-specific products.
Innovation Solution
Portable interactive product displays that can be quickly assembled and disassembled, using inaudible tones, sensors, and facial recognition to identify users and adapt product offerings based on local preferences, allowing for dynamic selection and delivery of region-specific products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If product displays use static product selections (vending machines, fixed store fixtures), then device complexity is reduced and ease of manufacture is improved, but adaptability to user preferences and region-specific customization deteriorates
Solution Approach 1:
The portable product display system integrates multiple functions into a single device: it can identify users through facial recognition, detect presence via sensors, communicate through inaudible tones, display product information, and process transactions. This multi-functional approach enables adaptability to different user preferences and regions without requiring separate specialized devices for each function.
Solution Approach 2:
The system uses an intermediary mobile device (smartphone) to bridge the gap between the portable display and the user. The mobile device receives inaudible tones from the display, processes user identification data, and communicates product information back to the user, enabling personalized interactions without complicating the core display hardware.
2Adaptability or versatility
If product displays are fixed at specific locations (store fixtures, mall displays), then ease of operation is improved and users can access products conveniently, but portability and ability to reach different user regions deteriorates
Solution Approach 1:
The product display system transitions from a static fixed-location model to a dynamic portable model. The display can be moved to different locations and temporarily set up in various regions, adapting to where users are located rather than requiring users to travel to where the display is fixed. Sensors detect user presence and automatically activate the display when needed.
Solution Approach 2:
The portable display system automatically detects user presence through sensors and inaudible tones, identifies users via facial recognition, and presents personalized product information without requiring users to actively seek out or navigate to a fixed display location. The system serves users wherever they are within range.
3Adaptability or versatility
If product selections are based on general availability and pricing, then ease of manufacture and inventory management are improved, but product relevance to individual user preferences deteriorates
Solution Approach 1:
The system uses feedback from user identification (facial recognition) and mobile device communication to dynamically adjust product selections. By receiving user preference data from the mobile device and analyzing facial recognition results, the system tailors product recommendations to individual users rather than displaying generic available inventory, creating a closed-loop personalized selection system.
Solution Approach 2:
The product display system applies local quality by customizing product selections for each individual user based on their preferences, location, and historical data received through the mobile device. Different users see different product recommendations at the same physical display, with each user experiencing a locally optimized product selection tailored to their specific needs and preferences.
4Productivity
If interactive features (facial recognition, sensors, inaudible tones) are added to product displays, then user engagement and personalization are improved, but ease of manufacture and device complexity deteriorates
Solution Approach 1:
The interactive system is segmented into separate functional modules: facial recognition camera, sensor array for presence detection, speaker for inaudible tones, display screen, and processing unit. Each module can be manufactured independently using standard components and then integrated into the portable display, making the complex system easier to manufacture and maintain through modular assembly.

AI summary
Systems, methods, and computer-readable media are disclosed for systems and methods for personalizing portable shopping displays using mobile devices and inaudible tones. Example methods may include causing a first inaudible tone to be emitted by a speaker, the first inaudible tone configured to initiate a change in a user interface at a mobile device, determining a second inaudible tone from a user device using a microphone, the second inaudible tone including a user identifier of a user, and determining a user interaction with a product at a product display. Certain example methods may include determining user preference data, and causing presentation of product information for the product using the user preference data.
