Imaging Device Field of View Adjustment via Head Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging devices do not effectively adjust their field of view in response to operator head motion, leading to disorientation, nausea, and visual discomfort, as they fail to permit motion parallax and familiar viewing experiences.
Innovation Solution
A computer-assisted device with a repositionable structure and control unit that receives head motion signals and adjusts the field of view of the imaging device based on commanded motion, determined by the head motion, within specific threshold limits to ensure alignment with the operator's expected view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the imaging device maintains a fixed field of view, then the device complexity is reduced, but the operator experiences disorientation and visual discomfort when moving their head
Solution Approach 1:
The patent applies the dynamics principle by making the field of view adjustable and responsive to head motion. The imaging device transitions from a fixed field of view to a dynamic system that automatically adjusts its viewing angle based on detected head position, thereby improving viewing comfort while managing complexity through automated control.
Solution Approach 2:
The patent implements feedback by using head motion sensors to detect the operator's head position and feeding this information back to the control unit, which then adjusts the imaging device's field of view accordingly. This closed-loop system ensures the displayed view remains aligned with the operator's expected perspective, eliminating disorientation.
2Ease of operation
If the field of view is adjusted continuously to follow head motion, then viewing comfort is improved, but the device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The patent applies self-service by enabling the imaging device to automatically adjust its field of view based on head motion detection without requiring manual intervention from the operator. The system serves itself by using sensor input to autonomously control the imaging device's viewing angle, improving intuitiveness while containing complexity through automated self-adjustment.
3Adaptability or versatility
If the imaging device does not adjust to head motion, then the device complexity is minimized, but motion parallax cannot be perceived and the viewing experience becomes disorienting
Solution Approach 1:
The patent applies parameter changes by modifying the field of view parameter of the imaging device in response to head motion. The control unit changes the viewing angle and positioning parameters of the imaging device to match the operator's head position, thereby improving adaptability to head motion while managing complexity through controlled parameter adjustment.

AI summary
Techniques are disclosed for imaging device control in a viewing system that includes a repositionable structure configured to support an imaging device, and a control unit communicably coupled to the repositionable structure. The control unit is configured to receive head motion signals indicative of a head motion of a head of an operator relative to a reference, and in response to determining that the head motion signals indicate that the head motion does not exceed a threshold amount in a direction, cause a field of view of the imaging device to be adjusted in accordance with a commanded motion by commanding movement of at least one of the repositionable structure or the imaging device, where the commanded motion is determined based on the head motion.
