1Ease of operation
If visual analysis of product images is used for online shopping, then the shopping process is convenient and remote, but the ability to judge product texture and roughness is insufficient
Solution Approach 1:
The patent introduces an intermediary system that includes a sensor array to capture microscopic surface data, image processing module to analyze the data, and tactile feedback device to reproduce texture information. This intermediary translates visual information into tactile representations, allowing remote shoppers to perceive surface characteristics without direct contact.
Solution Approach 2:
The patent replaces the mechanical action of direct tactile contact with an electronic-optical system. Instead of requiring the user's finger to physically touch the product, the system uses sensors to capture surface data and electronic displays with haptic feedback to simulate texture, substituting mechanical interaction with electronic mediation.
2Measurement precision
If direct physical contact with the product is required to gauge quality and texture, then accurate tactile information is obtained, but the convenience of remote shopping is lost
Solution Approach 1:
The patent creates a tactile copy or representation of the product's surface characteristics. The sensor array captures microscopic surface data, which is processed into tactile feedback patterns that replicate the original surface texture. This allows the remote user to experience a copied tactile sensation without physical contact with the actual product.
Solution Approach 2:
The system acts as an intermediary between the product and the remote user, translating physical surface properties into electronic signals that can be transmitted and reproduced. The intermediary includes data capture sensors, processing algorithms, and haptic feedback mechanisms that bridge the gap between distant locations while preserving tactile information accuracy.
3Loss of information
If microscopic surface analysis is performed to generate tactile representations, then accurate texture information is provided to consumers, but system complexity increases
Solution Approach 1:
The patent divides the complex task of texture analysis into separate functional modules: a sensor array for data capture, an image processing module for analysis, and a tactile feedback device for output. This segmentation allows each component to specialize in a specific function, managing overall system complexity while achieving comprehensive texture information.
Solution Approach 2:
The system incorporates automated image processing algorithms that independently analyze captured surface data and generate appropriate tactile feedback patterns without requiring manual intervention. The processing module self-adjusts parameters and selects feedback intensity based on the analyzed surface characteristics, reducing operational complexity.
