Solution Overview

Problem

Mobile computing devices face limitations in replicating a high-resolution, large-format display due to size constraints and require hands-dependent input methods, necessitating a hands-free, portable solution for enhanced mobility and usability.

Innovation Solution

A wireless computing headset with high-resolution micro-displays and optics, allowing users to navigate and control a virtual display environment using head movements and voice commands, enabling hands-free interaction with user-configurable boards and widgets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If mobile computing devices use small form factor displays to maintain mobility, then portability is improved, but display resolution and visual quality deteriorate

Engineering Contradiction:

Improvedevice sizeVSAvoiddisplay resolution

Core Design Contradiction:

Length of moving objectVSMeasurement precision

Solution Approach 1:

The patent transitions from a 2D handheld display to a 3D volumetric display environment where multiple virtual boards exist in three-dimensional space. Users can navigate this 3D space using head movements, effectively adding a spatial dimension to the display interface that overcomes the physical size limitations of mobile devices while maintaining high information density and visual quality.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If mobile devices use touch-screen or keyboard interfaces, then data input capability is improved, but hands-free operation capability deteriorates

Engineering Contradiction:

Improvedata input capabilityVSAvoidhands-free operation capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical touch-screen and keyboard input systems with a head-tracking based control system. Head movements are detected and translated into navigation commands within the virtual display environment, eliminating the need for hands-dependent input devices while maintaining intuitive and precise control capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If headset computers use head movement control for navigation, then hands-free operation is improved, but user input precision deteriorates

Engineering Contradiction:

Improvehands-free operationVSAvoiduser input precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments the virtual display environment into multiple discrete boards arranged in a 3D space. Head movements are used to navigate between these segmented boards rather than requiring precise control within a continuous space. This segmentation approach maintains hands-free operation while improving effective input precision through discrete board selection.

Inventive Principle:

Principle #1Segmentation

AI summary

To assist with hands-free computing, the Head Mounted Display or Headset Computer utilizes a series of user configurable Home Pages that contain the shortcuts and widgets the user wants and one or more head movements. This allows the user to design a user interface environment which gives desired information, in the desired order.
