Solution Overview

Problem

The ability for users to interact with virtual objects in VR or AR environments, or with AI, is limited, often constrained by processing power and bandwidth, especially in systems using mobile devices.

Innovation Solution

A wearable computing apparatus worn on the hand, comprising a first subassembly with processors, memory, and sensors, and a second subassembly with flexible leads attached to fingers, providing haptic feedback and positional tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If users wear a head-mounted display for VR/AR interactions, then visual immersion is improved, but processing power and bandwidth are constrained

Engineering Contradiction:
Improvevisual immersionVSAvoidprocessing power
Core Design Contradiction:
Illumination intensityVSPower

Solution Approach 1:

The system divides the computing apparatus into two separate wearable components: a head-mounted display for visual output and a hand-worn controller for input and processing. This segmentation allows each device to specialize in specific functions, reducing the processing burden on the HMD while maintaining immersive visual experiences.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hand-worn controller acts as an intermediary device between the user and the VR/AR system. It captures hand and finger movements through sensors and transmits this data wirelessly to the HMD, reducing the bandwidth and processing requirements of the head-mounted display while enabling sophisticated interaction capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If handheld controllers are used for interaction, then ease of operation is improved, but sensory feedback and positional tracking are limited by processing power

Engineering Contradiction:
Improveinteraction capabilityVSAvoidpositional tracking
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical tracking systems with sensor-based detection. The hand-worn controller incorporates sensors that directly detect hand and finger position, orientation, and movement, providing high-precision positional tracking without relying on complex mechanical mechanisms or extensive processing power.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The hand-worn controller performs local processing of sensor data at the point of interaction. By processing positional and sensory data locally in the hand device rather than transmitting all raw data to the HMD, the system improves measurement precision while reducing bandwidth requirements.

Inventive Principle:
Principle #25Self-service

3Weight of moving object

If mobile computing devices are used, then portability is improved, but computing resources are severely limited

Engineering Contradiction:
ImproveportabilityVSAvoidcomputing resources
Core Design Contradiction:
Weight of moving objectVSProductivity

Solution Approach 1:

The system segments computing functions between the mobile device and the hand-worn controller. The mobile device serves as a portable power and communication hub, while the controller handles real-time interaction processing. This allows the use of lighter mobile devices without sacrificing computing capability for VR/AR interactions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the interaction processing functions from the mobile device and places them in the hand-worn controller. This extraction allows the mobile device to remain lightweight and portable while the controller, which has dedicated sensors and processors for interaction, handles the computationally intensive tasks of tracking and feedback.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Wearable computing apparatuses, which can be adapted to be worn on a user's hand, are provided for augmented reality, virtual reality, and artificial intelligence interactions. Generally, the wearable computing apparatus can include a first subassembly comprising one or more processors, non-transitory memory for storing instructions, at least one haptic motor, and a first set of sensors configured to measure positional characteristics associated with a user's hand. The wearable computing apparatus can further comprise a second subassembly removably coupled to the first subassembly, the second subassembly including a plurality of leads each of which is attached to a finger and comprises a distal portion that houses a haptic motor and a second set of sensors. The second set of sensors is configured to measure positional characteristics associated with the user's fingers.
