Solution Overview

Problem

Wearable head-mounted displays often face user interface challenges due to left-right ambiguity when using side-mounted touchscreens, as it is not intuitive for users to determine whether a forward or backward gesture on the touchscreen results in a right or left movement of the cursor on the display.

Innovation Solution

Incorporating a processor and display elements within a wearable frame structure that includes a touch-operable input device, where the display information appears at least partially curved, helping users intuitively navigate the interface by resolving the left-right ambiguity through curvature-based interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a side-mounted touchscreen is used in head-mounted displays, then the device can provide input functionality, but left-right ambiguity occurs making it non-intuitive for users to determine cursor movement direction

Engineering Contradiction:
Improveintuitiveness of cursor movementVSAvoidspatial orientation information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces a third dimension (depth/curvature) to the display by rendering the display surface as curved rather than flat. This curvature provides spatial orientation cues that resolve the left-right ambiguity on the orthogonal touchscreen, allowing users to intuitively understand cursor movement direction by mapping touchscreen gestures to their corresponding positions on the curved display surface.

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

2Device complexity

If the touchscreen is positioned orthogonal to the display, then the input device can be compactly integrated, but spatial orientation becomes ambiguous

Engineering Contradiction:
Improveintegration of input deviceVSAvoidspatial mapping clarity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent applies curvature to the display surface to create a spherical or curved geometry that provides natural spatial orientation. The curved display surface creates depth perception and directional cues that help users understand the relationship between touchscreen gestures and cursor movement, transforming the flat orthogonal interface into a spatially-aware interface.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

Disclosed are systems, methods, and devices for interfacing with a wearable heads-up display via a touch-operable input device. The wearable heads-up display may include a display element for receiving and displaying display information received from a processor, and may also include a wearable frame structure supporting the display element and having a side-arm extending away from the display element. In some embodiments, the display information may appear at least partially curved to a user. In some embodiments, only a portion of the display information is shown on the at least one display element. The side-arm may be configured to secure the heads-up display to a user's body in a manner such that the display element is disposed within a field of view of the user. The touch-operable input device secured to the wearable frame structure is configured to sense at least one of a position and movement of a touch or finger along a planar direction relative to a surface of the input device, and to provide corresponding input information to the processor. A navigation tool may also be displayed on the at least one display element for indicating the location of the touch on the touch-operable input device.
