Solution Overview

Problem

Mobile computing devices face limitations in providing a hands-free, high-quality, and portable visual experience due to their small size and hands-dependent user interfaces, which restricts their ability to effectively display large-format, high-resolution graphics and video content.

Innovation Solution

A wearable headset system (WHS) is developed, integrating micro-displays, sensors, and communication components to provide a hands-free computing and communication interface. This system includes a head-mounted display with micro-displays for high-resolution visuals, audio input/output, and sensors for gesture control, allowing users to interact with data and video content using voice commands and head movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If mobile computing devices use small form factors to promote mobility, then portability is improved, but the ability to display large-format, high-resolution graphics is worsened

Engineering Contradiction:
Improvedevice portabilityVSAvoiddisplay area
Core Design Contradiction:
Weight of moving objectVSArea of stationary object

Solution Approach 1:

The patent projects the display interface from a traditional 2D screen onto a 3D spatial environment using augmented reality technology. Virtual objects and interfaces are rendered in three-dimensional space, allowing users to access large-format displays without being constrained by physical screen size. The system uses depth sensing and spatial mapping to create immersive visual experiences that extend beyond the limitations of mobile device form factors.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces external projection surfaces and augmented reality environments as intermediaries between the mobile device and the user's visual perception. Instead of directly displaying content on the device screen, the system projects visual information onto external surfaces or overlays it in the user's field of view, effectively using the environment itself as the display medium.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If mobile devices use hands-dependent interfaces (keyboard or touch-screen), then input precision is improved, but hands-free operation capability is worsened

Engineering Contradiction:
Improveinput precisionVSAvoidhands-free operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces mechanical input methods (physical keyboards and touch screens) with voice recognition and gesture-based control systems. The system uses acoustic sensors to capture and interpret spoken commands, and motion sensors to detect hand gestures, converting these into digital input signals. This substitution eliminates the need for physical contact while maintaining input precision through advanced signal processing and pattern recognition algorithms.

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

Solution Approach 2:

The patent implements systems that automatically interpret and execute user intent without requiring manual confirmation or correction. Voice commands are processed and executed directly, and gesture inputs are automatically translated into appropriate device actions. The system learns from user behavior patterns to improve accuracy over time, reducing the need for hands-on adjustment or correction.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If head-mounted displays integrate multiple sensor components for gesture control, then hands-free interface capability is improved, but device complexity is worsened

Engineering Contradiction:
Improvehands-free interface capabilityVSAvoidsensor component integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs multi-functional sensor components that perform multiple functions within a single integrated unit. For example, the camera system serves both as a visual sensor for augmented reality rendering and as a gesture recognition sensor by analyzing hand movements in the field of view. The microphone array functions both as an audio input device and as a spatial positioning sensor for determining the direction and distance of sound sources, thereby supporting both voice commands and spatial audio features.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A headset display system may comprise a head mounted display and a remote host device. The head mounted display may comprise a microdisplay and sensing components. The remote host device may communicate with the head mounted display, and formulate a task requirement based on information associated with a user of the headset display system. The remote host device may further search for and identify one or more wireless resources currently available to the remote host device, determine which of the identified wireless resources are suitable for satisfying the task requirement, and utilize the determined wireless resources to accomplish a task corresponding to the task requirement. The wireless resources may comprise at least one entity, external to the headset display system, that (i) generates a physical informational parameter, (ii) generates a process result, (iii) performs a data processing task, and/or (iv) accesses a communication and/or information storage resource.
