Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable computing devices are limited in their ability to provide comprehensive 3D mapping, imaging, and multi-interface remote controlling capabilities, particularly in enabling the augmentation of real-world objects and environments into virtual spaces and vice versa, with a lack of integration of advanced light and optical technologies for dynamic gesture recognition and secure user verification.
Innovation Solution
A wearable wireless wrist console that utilizes light and optical depth mapping, structured light imaging, and stereoscopic or plenoptic lens arrays for 3D imaging and modeling, combined with motion and orientation sensors, to enable real-time gesture recognition, user verification, and multimedia streaming, allowing for the integration of virtual and physical environments through wireless networking and projection systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-location depth mapping systems are used, then depth mapping capability is provided, but mobility and versatility are limited
Solution Approach 1:
The wrist console integrates multiple functions including depth mapping, gesture recognition, voice recognition, and wireless communication into a single wearable device. The device serves as both a control interface and a computing platform, eliminating the need for separate fixed-location mapping systems while providing mobile 3D imaging capabilities through integrated light emitters, sensors, and processors.
Solution Approach 2:
The patent embeds multiple subsystems within the wrist console structure, including light emitters, sensors, processors, and communication modules nested within the wearable device housing. This nested arrangement allows the complex functionality to be contained within a compact form factor that can be worn on the wrist, providing mobility without proportionally increasing external system complexity.
2Measurement precision
If advanced light and optical technologies are integrated, then 3D imaging and gesture recognition capabilities are enhanced, but device complexity increases
Solution Approach 1:
The optical system is divided into separate functional modules: light emitters for structured light projection, sensors for capturing reflected light patterns, and processors for analyzing the data. This segmentation allows each component to be optimized independently while working together to achieve precise 3D imaging and gesture recognition without requiring all components to be equally complex.
Solution Approach 2:
The patent uses structured light patterns as an intermediary between the light emitters and the sensors. The projected light patterns serve as a medium that carries depth and spatial information, allowing the system to achieve precise 3D imaging through relatively simple sensor arrays rather than requiring complex direct measurement apparatus.
3Measurement precision
If multiple sensors and light emitters are placed on the wrist device, then gesture recognition accuracy is improved, but device weight and size increase
Solution Approach 1:
The wrist console utilizes thin-film construction and flexible circuit boards to accommodate multiple sensors and light emitters without significantly increasing device weight. The sensors and emitters are mounted on thin substrates that can be integrated into the wristband structure, distributing the weight across a larger surface area and reducing the concentration of mass at any single point.
Solution Approach 2:
The system uses optical copying principles where sensors capture reflected light patterns that contain depth and gesture information. Rather than requiring direct physical contact or complex mechanical measurement apparatus, the system creates optical copies of the hand and gesture movements, allowing accurate gesture recognition with minimal physical sensors.
4Adaptability or versatility
If wireless multimedia streaming and projection systems are added, then virtual-environment integration is enhanced, but energy consumption increases
Solution Approach 1:
The wireless multimedia streaming and projection functions operate periodically rather than continuously. The system activates these functions only when needed for specific tasks such as virtual object manipulation or augmented reality display, allowing the device to conserve energy during normal operation while still providing enhanced virtual-environment integration when required.
Solution Approach 2:
The projection and streaming capabilities are implemented as dynamic, on-demand functions rather than always-active systems. The wrist console can adjust its operational mode based on task requirements, enabling virtual-environment integration only when the user interacts with virtual objects or requires augmented reality features, thereby reducing overall energy consumption while maintaining versatility.
