Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for analyzing shopper behavior in shopping environments are expensive and do not scale well for large-scale studies, as they require skilled labor for eye movement cameras and are costly for brainwave sensors, resulting in limited reliable data on shoppers' views and experiences.
Innovation Solution
A point of view shopper camera system comprising an eye camera, head orientation sensor, position tracking sensor, and analysis computing device to estimate a shopper's field of view by capturing images and combining them with orientation and position data, allowing for accurate analysis of shopper behavior without the need for expensive equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive eye movement cameras and brainwave sensors are used to accurately measure shopper behavior, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses a camera to capture images of the shopping environment from the shopper's perspective, creating a visual copy of what the shopper sees. This camera-based approach replaces complex eye movement tracking equipment while still providing data about shopper attention and behavior through image analysis of captured scenes
Solution Approach 2:
The invention employs inexpensive, portable electronic components including a camera, accelerometer, and compass that can be easily deployed and discarded for each study session. These low-cost components replace expensive, sophisticated measurement equipment while providing sufficient data for behavioral analysis
2Measurement precision
If skilled labor is required to operate eye movement cameras, then measurement precision is improved, but productivity decreases due to limited operator availability
Solution Approach 1:
The system automatically captures images and records sensor data without requiring continuous human intervention. The camera takes photos at scheduled intervals or triggered by motion, and the accelerometer and compass automatically track head orientation and movement, eliminating the need for skilled operators to manually control equipment or record measurements
Solution Approach 2:
The patent replaces manual, skill-based operation with automated electronic sensing and data collection. Sensors automatically detect head movements and orientations, and the system autonomously processes this data to determine shopper behavior, replacing the need for skilled human operators with automated computational analysis
3Measurement precision
If brainwave sensors are used to measure shopper brain activity, then measurement precision is improved, but cost increases making large scale studies infeasible
Solution Approach 1:
The system uses inexpensive, disposable-like electronic components including cameras and sensors that can be deployed to large numbers of shoppers without significant cost increase. Each shopper receives a portable device that costs a fraction of brainwave sensors, enabling studies with hundreds or thousands of participants rather than a handful
4Measurement precision
If expensive equipment is used for shopper behavior analysis, then measurement precision is improved, but loss of time increases due to equipment setup and technician coordination
Solution Approach 1:
The system is designed to be self-configuring and self-operating, automatically calibrating sensors and beginning data collection without extensive technician setup. The portable device can be quickly distributed to shoppers and begins autonomous operation, eliminating time-consuming equipment setup and technician coordination required by complex measurement systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides cost-effective and scalable data collection, enabling accurate estimation of shopper views and behaviors, reducing costs associated with technician labor and providing quantitative metrics on shopper interactions with store displays.
Implementation Method 1
The eye camera may be configured to be mounted to the head of the shopper, and to capture a still or moving image of the field of view of the shopper... head orientation data from the head orientation sensor
Implementation Method 2
a position tracking sensor to identify a shopper's position
Implementation Method 3
The analysis computing device may be configured to receive the captured image data from the eye camera, head orientation data from the head orientation sensor, and the shopper's position data from the position tracking sensor, and determine an estimated field of view of the shopper during a trip in a shopping environment
