Haptic Camera Control with Gaze-Directed Opposing Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system and method that allows image capture without pointing a camera directly at a person, addressing concerns of privacy and offense.
Innovation Solution
A wearable imaging device with multiple image-sensing devices mounted in opposing directions, including a selfie and landscape camera, uses a controller to analyze the user's direction of view and electronically zoom in on a region of interest by adjusting the landscape camera's focus based on the user's gaze direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is pointed directly at a person to capture an image, then the image quality and clarity are improved, but it may cause privacy concerns and offense to the subject
Solution Approach 1:
The patent uses an intermediary device (the wearable imaging device with multiple sensors) that captures images without requiring direct line-of-sight from the user to the subject. The system processes images through multiple sensors positioned at different angles, allowing the user to capture images of subjects without pointing the camera directly at them, thus resolving the contradiction between image quality and privacy concerns
2Object-affected harmful factors
If a camera is pointed away from a person to avoid privacy issues, then privacy concerns are reduced, but the ability to capture clear images of the subject is worsened
Solution Approach 1:
The patent divides the imaging function into multiple segments by using several image sensors positioned at different orientations (front, back, side cameras). This segmentation allows the system to capture images of subjects from various angles without requiring the user to point any single camera directly at the subject, thereby maintaining both privacy and image quality
3Adaptability or versatility
If multiple image-sensing devices are mounted in opposing directions to enable indirect imaging, then the ability to capture images without pointing camera at subject is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing a wearable device that integrates multiple image sensors, processors, and communication modules into a single universal platform. This multi-functional design allows the device to perform various imaging functions (front-facing, back-facing, side-facing cameras) and additional functions like image processing and wireless communication, thereby managing the complexity through consolidation rather than separate devices

AI summary
An imaging device including a plurality of image-sensors including at least a first image sensor and a second image sensor mounted in substantially opposing directions, and a controller coupled to the sensors. The controller captures the first image content from the first image sensor, and the second image content from the second image sensor, substantially simultaneously, then analyzes the first image content to detect a user of the imaging device, and to determine a direction in which the user is looking, The controller then captures the second image from the second image sensor, and selects a zoom part of the second image. The zoom part located in the user looking direction. Alternatively, the controller selects a second image sensor from the plurality of image sensors, where the selected second image sensor is directed in the user looking direction.
