Solution Overview

Problem

Conventional pop-up notifications in vehicles lack predictability and clarity regarding their duration, making it unclear to drivers whether an operation is necessary, especially in limited field of view conditions like head-up displays, where relevant information is often delayed or briefly visible.

Innovation Solution

A device with an input interface for receiving notice and vehicle data, an analysis circuit to generate control commands for an augmented reality (AR) display, and an output interface to transmit these commands, creating a dynamic depiction of notifications that convey validity ranges, allowing drivers to intuitively understand and detect the relevance of the information without diverting their attention from the road.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional pop-up notifications are used with timeout, then the display time is limited, but the user cannot predict how long the pop-up will be visible and the temporary character is not immediately apparent

Engineering Contradiction:
Improveclarity of information durationVSAvoiduser predictability
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent applies dynamics by transitioning from static timeout-based notifications to dynamic visual representations that change over time. The notice is depicted with visual cues (such as shrinking boundaries or fading effects) that dynamically indicate the remaining validity period, allowing users to intuitively understand how long the information will remain visible without relying on fixed timeout values.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes color changes to convey the temporal status of notifications. Different colors or color intensities are used to indicate the remaining validity period of a notice, making the duration information immediately apparent to users through visual perception rather than requiring them to interpret timeout settings or wait for the notification to disappear.

Inventive Principle:
Principle #32Color changes

2Area of stationary object

If maximum field of view with 100% windshield coverage is used, then more information is visible, but relevant objects are only visible very belatedly or very briefly at high speed

Engineering Contradiction:
Improvewindshield coverageVSAvoidvisibility time of relevant objects
Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

The patent applies preliminary action by projecting notification information about relevant objects (such as traffic signs or hazards) in advance of the vehicle's actual position. The AR system calculates and displays information at a projected future location where the object will be visible, giving the driver advance notice and sufficient time to react before the object actually enters the visible field.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent transitions from two-dimensional windshield projection to three-dimensional spatial positioning in the driver's field of view. By placing virtual notifications at specific distances and positions that correspond to the actual spatial location of relevant objects, the system creates a depth-perceived interface that naturally guides the driver's attention to areas of interest without requiring maximum windshield coverage.

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

3Ease of operation

If conventional head-up display is used, then the field of view is limited, but it is technically impossible to directly mark objects in the environment

Engineering Contradiction:
Improvefield of view accessibilityVSAvoidobject marking capability
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent merges the notification interface with the actual environmental context by superimposing virtual notices directly onto or near the physical objects they reference. This integration allows the driver to perceive both the notification and the relevant object simultaneously in the same field of view, eliminating the need to shift attention between separate display areas and enabling direct association between information and its source.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The AR display system acts as an intermediary that bridges the gap between the driver and environmental objects. Instead of merely displaying abstract notifications on a limited HUD, the system projects contextualized information that mediates the driver's perception of relevant objects, enhancing visibility and understanding without requiring the driver to move their head or eyes to separate locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The disclosure relates to a device for the improved visualization of a notice in a motor vehicle. A contact-analog head-up display places information in direct contact with the environment. In contrast to conventional head-up displays, the information appears as part of the environment. Some embodiments provide an information container that is placed at a distance x from the vehicle which grows corresponding to the reduction of the distance x, and is placed fixed relative to the environment to produce the effect of a container located in reality. The necessity of an interaction may be communicated by the element remaining stationary. That is, shortly before the position of the information container is reached, it remains immobile in the field of vision and is “pushed” in front of the ego vehicle. This makes it immediately apparent that an operation is needed to acknowledge the pop-up respectively to thereby trigger an action.
