Remote Imaging Control via Priority-Based Body Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses lack the ability to be remotely controlled with high practicality and usability, particularly in scenarios where multiple subjects are present, leading to potential unintended operations due to unconscious motions.
Innovation Solution
An operation input apparatus that includes a body portion detection unit, state determination unit, priority-level setting unit, and control unit, allowing users to remotely control imaging devices through specific body motions, with priority levels set based on subject distance, face position, and motion speed to differentiate intended from unintended commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control operation is enabled by detecting body portions in images, then usability is improved, but reliability deteriorates due to potential unintended operations from unconscious motions
Solution Approach 1:
The patent changes parameters such as determination allowance degrees, priority levels, and motion criteria to distinguish between intentional and unintentional gestures. By adjusting these parameters dynamically, the system maintains high usability while preventing unintended operations.
Solution Approach 2:
The system incorporates feedback mechanisms where the determination result of motion detection influences subsequent operations. The control unit uses feedback from the operation determination unit to decide whether to execute the remote control function, thereby ensuring reliable operation.
2Productivity
If motion detection sensitivity is increased to improve command recognition, then productivity is improved, but reliability deteriorates due to false detection of unconscious motions
Solution Approach 1:
The patent applies different determination allowance degrees to different body portions based on their priority levels. High-priority body portions (likely to be intentionally moved) have lower determination allowances, while low-priority body portions have higher allowances, reducing false detections.
Solution Approach 2:
The system dynamically adjusts determination allowance degrees and priority levels based on the detected body portion and its state, enabling accurate command recognition while minimizing false detections of unconscious motions.
3Reliability
If priority levels are set for multiple body portions to differentiate intended motions, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent uses priority levels and determination allowance degrees as adjustable parameters to manage the complexity of multi-body-portion detection. By systematically assigning priorities and allowances, the system maintains reliability without excessive complexity.

AI summary
An operation input apparatus includes a body portion detection unit for receiving image data and detecting a certain body portion of a subject in an image of the image data, a state determination unit for determining a certain state corresponding to a priority-level setting condition for each body portion, a priority-level setting unit for setting priority levels to the individual body portions in accordance with results of the determination, an operation determination unit for determining whether the body portions performed a predetermined motion corresponding to a certain operation in accordance with determination allowance degrees of the body portions serving as determination subjects which are set in accordance with the priority levels, and a control unit for controlling the operation input apparatus so that the operation input apparatus performs a predetermined operation in accordance with the determination that the certain motion corresponding to the certain operation has been performed.
