Composite Display for Virtual Exercise Instruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in virtual worlds for exercise and rehabilitation instruction face confusion in linking their real-world movements to their digital representation, especially with complex motions, due to difficulties in determining which limbs to move and the need for multiple angles of view, exacerbated by motion-tracking cameras.
Innovation Solution
The system generates a composite display with synchronous multi-view animation, using a virtual animated 'mirror' to provide additional angles of view and feedback, including a front and back view of the instructional avatar, and dynamically adjusts the mirror element for context, such as obscuration and zoom, to guide user body motion effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single mirrored view of the avatar is used, then the user can see their digital representation, but the user cannot understand complex motions from multiple angles
Solution Approach 1:
The display is segmented into multiple independent viewports, each showing a different angle of the avatar (front view, back view, side views). This allows users to see complex motions from multiple perspectives simultaneously without requiring a single complex rotating display mechanism.
Solution Approach 2:
The system transitions from a single 2D mirrored display to a multi-dimensional arrangement of multiple 2D viewports, effectively adding spatial dimensionality to the information presentation. This enables comprehensive viewing of avatar motions from front, back, and side angles within the same display space.
2Ease of operation
If the avatar is mirrored to match real-world movement, then simple movements are clear, but complex clinical motions become confusing
Solution Approach 1:
The motion information is segmented across multiple viewports, with each viewport dedicated to showing a specific angle or aspect of the avatar's motion. This segmentation preserves all motion details from different perspectives simultaneously, eliminating the information loss that occurs in single-view mirrored displays.
Solution Approach 2:
The multi-view display system serves multiple functions simultaneously: it provides mirrored views for simple motions, angled views for complex motions, and can be configured to show specific perspectives based on the exercise type, making it universally applicable to both simple and complex clinical rehabilitation motions.
3Measurement precision
If motion-tracking cameras are used to capture user movement, then real-time tracking is achieved, but the user must stand in specific positions which limits flexibility
Solution Approach 1:
The system dynamically adjusts which avatar views are displayed based on the user's actual position and the type of motion being performed. Rather than requiring the user to position themselves relative to the camera, the display adapts to show the most relevant perspectives for accurate motion tracking and understanding.
Solution Approach 2:
The system provides visual feedback through multiple avatar perspectives that help users understand whether their motion is being tracked correctly. The multi-view display shows users how their movements appear from different angles, enabling self-correction without requiring precise positioning relative to the camera.

AI summary
Methods, systems and apparatus are provided for generating visual instruction to a user of a system, such as for exercise instruction or rehabilitation purposes. Preferably, the system includes a user imaging system with the system generating an output adapted to couple to a display device. The systems and methods serve to guide a user body motion. In one preferred embodiment, the method includes the steps of receiving first user positional information from the user imaging system, and then generating a first mirror image of the user positional information. Additionally, the method includes generating a first instructional image having the same positional orientation as the first mirror image of the user positional information. Finally, the method and system generate a composite output display including the first mirror image of the user positional information and the first instructional image.
