Equipment Control Device Using Hand Shape and Eye Point Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment control systems that rely solely on hand orientation for remote operation are prone to malfunctions, as they lack precise alignment and shape recognition, leading to unintended equipment operation.
Innovation Solution
An equipment control device that receives sensing information on the position, shape, and movement of an object, including the eye point of a user, to determine command information for operating equipment only when the object is in a predetermined shape and aligned with the equipment, reducing malfunctions by aligning the user's hand with the equipment and interpreting hand movements as intended operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If equipment control is based solely on hand orientation, then operation simplicity is improved, but equipment reliability deteriorates due to high malfunction possibility
Solution Approach 1:
The patent segments the hand into multiple detection points (eye point, fingertip point, and intermediate points) to independently verify alignment and shape conditions. This segmentation allows the system to check both orientation and specific hand shape simultaneously, resolving the contradiction by adding verification layers without requiring complex user input
Solution Approach 2:
The patent introduces an intermediary verification mechanism that checks whether the hand forms a predetermined shape (such as a V-shape or circle) before executing equipment control. This intermediary shape recognition acts as a mediator between simple orientation detection and reliable equipment operation, reducing malfunctions while maintaining intuitive control
2Reliability
If multiple parameters (position, shape, movement) are monitored for equipment control, then equipment reliability is improved, but device complexity increases
Solution Approach 1:
The patent makes the sensing device multi-functional by using it to detect multiple parameters (position, shape, movement) simultaneously. The same camera or sensor array that captures hand orientation also identifies hand shape and tracks movement, eliminating the need for separate sensors and reducing overall system complexity while improving reliability
Solution Approach 2:
The patent performs preliminary recognition of hand shape and position before processing movement commands. By pre-establishing the expected hand shape (such as a V-shape for volume control or circle for playback), the system simplifies subsequent movement interpretation, reducing computational complexity while ensuring reliable equipment control

AI summary
An equipment control device includes a receiver that receives sensing result information including a position, a shape, and a movement of a predetermined object and including a position of an eye point of a person, and a controller that, when the sensing result information indicates that the eye point, equipment placed at a predetermined position, and the object align and that the object is in a predetermined shape corresponding to the equipment in advance, determines command information causing to operate the equipment in accordance with the movement of the object in the predetermined shape to an equipment operating device.
