Solution Overview

Problem

Current heads-up display (HUD) control methods, such as speech commands, eye tracking, and head movements, are inefficient and socially awkward, leading to high computing overhead and user discomfort.

Innovation Solution

A mobile device system that transmits a portion of display data to a HUD device for display, while displaying a remaining portion on the mobile device, allowing for input data to update the HUD device, and providing alignment indicators for proper alignment, enabling efficient and private control of the HUD.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If speech commands are used to control HUD device, then control capability is provided, but computing overhead increases and social awkwardness occurs

Engineering Contradiction:
Improvecontrol capabilityVSAvoidcomputing overhead
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mobile device serves as an intermediary between the user and the HUD device. Instead of the HUD device independently processing complex speech recognition and natural language understanding, the mobile device receives simplified inputs (touch, keyboard, mouse) and translates them into control commands for the HUD, significantly reducing the computing overhead required at the HUD device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If eye tracking is used to control HUD device, then control capability is provided, but user fatigue increases and processing requirements intensify

Engineering Contradiction:
Improvecontrol capabilityVSAvoiduser fatigue
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The mobile device acts as an intermediary that receives inputs from standard input devices (touchscreen, keyboard, mouse) and converts them into control signals for the HUD. This eliminates the need for the user to continuously track and focus on the HUD display, thereby reducing eye fatigue and the intensive processing requirements associated with eye tracking systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If head movements are used to control HUD device, then control capability is provided, but social awkwardness increases

Engineering Contradiction:
Improvecontrol capabilityVSAvoidsocial awkwardness
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The mobile device serves as an intermediary that accepts inputs from conventional input methods (touch, keyboard, mouse) and translates them into control commands for the HUD. This approach eliminates the need for users to make noticeable head movements to control the display, thereby eliminating the social awkwardness associated with head movement-based control systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Loss of information

If display data is transmitted to HUD device, then privacy is maintained, but alignment precision must be ensured

Engineering Contradiction:
ImproveprivacyVSAvoidalignment precision
Core Design Contradiction:
Loss of informationVSManufacturing precision

Solution Approach 1:

The system employs alignment indicators that are visually displayed on the mobile device and detected by the HUD device. This feedback mechanism allows the HUD to accurately determine the position and orientation of the mobile device, enabling precise alignment of the displayed information with the physical mobile device without compromising user privacy.

Inventive Principle:
Principle #23Feedback

AI summary

A mobile device, system and method for controlling a heads-up display device is provided. A mobile device is in communication with a heads-up display (HUD) device. The mobile device is enabled to: transmit a portion of display data to the HUD device for display thereupon, rather than provide the portion to a display of the mobile device; and display a remaining portion of the display data at the display. The HUD device is enabled to: receive from the mobile device the display data for display at the HUD; display the data at the HUD.
