Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical sensor systems lack effective methods to guide human subjects' physical movements accurately within a physical environment for controlling electronic devices or performing tasks, especially in environments where traditional feedback mechanisms are limited or impractical.
Innovation Solution
The use of visual cues projected onto the human subject or into their field of view, derived from optical sensors and image projectors, to guide physical movements along a model path of travel, providing real-time feedback and feedforward information to enhance accuracy and technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional feedback mechanisms are used to guide physical movements, then the system structure is simple, but the movement accuracy and technique guidance are insufficient
Solution Approach 1:
The patent introduces visual cues as an intermediary element between the optical sensor system and the human subject. These visual cues (such as projected paths, target markers, or directional indicators) serve as a mediator that translates complex sensor data into intuitive visual guidance, enabling accurate movement feedback without requiring complex direct sensor-subject interaction mechanisms
Solution Approach 2:
The patent replaces traditional mechanical or physical feedback mechanisms with optical-based visual cue projection. Instead of using mechanical guides, physical constraints, or complex haptic feedback systems, the invention uses projected visual information to guide movement, substituting mechanical complexity with optical field-based guidance
2Manufacturing precision
If visual cues are projected onto the human subject, then movement guidance accuracy is improved, but the device complexity increases due to additional projectors and processing
Solution Approach 1:
The patent makes the optical sensor system multi-functional by enabling it to both detect human movement and project visual cues. This universal approach allows a single integrated system to perform multiple functions (sensing, processing, and visual feedback projection) rather than requiring separate dedicated components for each function, thereby managing complexity while maintaining high guidance accuracy
Solution Approach 2:
The patent combines the optical sensing functionality with visual projection capabilities into an integrated system. By merging the detection and feedback functions into a unified system architecture, the patent reduces overall system complexity compared to having completely separate sensing and projection systems, while maintaining precise movement guidance through coordinated operation
3Loss of information
If dedicated graphical displays are used to provide feedback, then information delivery is clear, but the system requires additional equipment and increases complexity
Solution Approach 1:
The patent uses projected visual cues in the physical environment as an intermediary to deliver feedback information, replacing dedicated graphical displays. These projected cues (such as illuminated paths or target zones) serve as a mediator that conveys movement guidance information directly in the subject's field of view, eliminating the need for separate display equipment while maintaining clear information delivery
Solution Approach 2:
The patent substitutes physical display equipment with optical field-based visual cue projection. Instead of using screens, monitors, or other dedicated display devices, the invention projects visual information directly into the movement space, replacing mechanical display systems with optical field-based information delivery

AI summary
Physical movement of a human subject may be guided by a visual cue. A physical environment may be observed to identify a current position of a body portion of the human subject. A model path of travel may be obtained for the body portion of the human subject. The visual cue may be projected onto the human subject and/or into a field of view of the human subject. The visual cue may indicate the model path of travel for the body portion of the human subject.
