Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pointing devices, such as laser pointers, lack dynamic adjustment of color and shape, limiting their interactive capabilities in extended reality environments.
Innovation Solution
A system and method for dynamically adjusting the visualization of a pointer based on its interaction with virtual content, using a control device that includes sensors to detect intersection with virtual content and change appearance characteristics accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional laser pointer or pointing implement is used, then the device structure remains simple and manufacturing is easy, but the pointer lacks dynamic adjustment of color and shape, limiting interactive capabilities
Solution Approach 1:
The patent applies dynamics by making the pointer visualization changeable and adjustable in real-time. The system dynamically modifies the appearance characteristics (color, shape, size) of the pointer based on user selections and contextual factors, transforming a static laser pointer into a dynamic, adaptive visualization tool that can respond to different interaction scenarios.
Solution Approach 2:
The patent implements parameter changes by allowing modification of key visual parameters including color, shape, and size of the pointer. The system enables users to select from multiple appearance characteristics and automatically adjusts these parameters based on detected contextual factors, thereby achieving versatile dynamic adjustment without requiring complete device redesign.
2Extent of automation
If manual adjustment of color and shape is implemented, then some adaptability is achieved, but the adjustment process requires user intervention and lacks automatic contextual response
Solution Approach 1:
The patent applies feedback by implementing a system that detects contextual factors (such as target object properties, environment conditions, or user behavior patterns) and automatically adjusts pointer appearance characteristics based on this feedback. This creates a closed-loop system where the pointer visualization responds automatically to contextual changes without requiring continuous manual user input.
Solution Approach 2:
The patent implements self-service by enabling the pointer system to automatically select and adjust its own appearance characteristics based on detected contextual factors. The system serves itself by making autonomous decisions about color, shape, and size adjustments, reducing the need for direct user intervention while maintaining adaptability to different situations.
3Adaptability or versatility
If a single color and shape pointer is used, then the device is simple to operate, but interactive capabilities in extended reality environments are limited
Solution Approach 1:
The patent applies local quality by allowing different portions or aspects of the pointer visualization to have different characteristics. The system can vary color, shape, and other appearance properties at different locations or in different contexts, enabling richer information communication and more nuanced interactive capabilities while maintaining operational simplicity through automated control.

AI summary
The method includes: while presenting virtual content, detecting a control device within a physical environment; determining whether a ray projecting from a portion of the control device intersects with the virtual content; presenting a first visualization associated with the ray projected from the portion of the control device with a first set of appearance characteristics according to a determination that the ray projected from the portion of the control device does not intersect with the virtual content; and presenting a second visualization associated with the ray projected from the portion of the control device different from the first visualization with a second set of appearance characteristics different from the first set of appearance characteristics according to a determination that the ray projected from the portion of the control device intersects with the virtual content.
