Vehicle Digital Assistant Status Display With Adaptive Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital assistants in vehicles lack efficient methods to communicate their status to users, making the human-machine interface complex and difficult to operate.
Innovation Solution
A method that generates an animated visual control object dynamically adapted to the display device, representing the status of the digital assistant through animated particle objects with specific shapes, motion patterns, and densities, which are determined by the status and display parameters, allowing flexible adaptation to different states and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional voice interface activation methods are used, then the digital assistant can be activated, but the human-machine interface becomes complex and difficult to operate
Solution Approach 1:
The patent uses different colors to represent different states of the digital assistant (e.g., blue for listening, green for processing, yellow for ready). This visual color-coding system simplifies user understanding of the assistant's status without adding complex interface elements, directly improving ease of operation while maintaining interface simplicity.
Solution Approach 2:
The patent dynamically changes visual parameters such as color, brightness, and animation patterns based on the digital assistant's operational state. These parameter changes provide intuitive feedback to users about the assistant's status, reducing the cognitive load required to understand system state and improving overall ease of operation.
2Loss of information
If status information is provided to users, then user understanding improves, but the interface becomes more complex
Solution Approach 1:
The patent segments status information into distinct visual components: color indicators for state, animation patterns for activity type, and intensity levels for processing status. This segmentation allows comprehensive status communication through simple, modular visual elements rather than complex text or icon combinations, reducing interface complexity while improving information delivery.
Solution Approach 2:
The patent adds visual dimensions (color, animation, brightness) to convey status information that would otherwise require text or verbal feedback. By encoding multiple status parameters in a single visual element across different dimensions, the system communicates comprehensive assistant state without adding interface complexity.
3Adaptability or versatility
If the digital assistant adapts to different display devices, then versatility improves, but system complexity increases
Solution Approach 1:
The patent implements a universal visual feedback system that operates across different display devices (head-up displays, instrument clusters, mobile devices) using the same core principles of color coding and animation patterns. This universal approach allows the system to adapt to various display contexts without requiring device-specific implementations, maintaining system simplicity while achieving broad versatility.

AI summary
A method for operating a digital assistant of a vehicle includes receiving a status of the digital assistant, and determining a display device for displaying the status of the digital assistant. The method further includes determining at least one display parameter of the display device. The method also includes generating an animated visual control object depending on the status of the digital assistant, the display device, and the at least one display parameter. The animated visual control object is deployed on the display device. A corresponding system performs the method.
