In-Vehicle Projection Interface for Voice Command Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle control systems, such as those using voice recognition, lack intuitive feedback, making it difficult for users to confirm command execution and leading to potential errors and a lack of engagement.
Innovation Solution
An in-vehicle projection system that projects a display interface to a user-specific region, showing the command execution process, enhancing user interaction and providing intuitive feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition control is used, then ease of operation is improved, but loss of information occurs because users cannot visually confirm command execution
Solution Approach 1:
A projection apparatus is introduced as an intermediary between the control apparatus and the user. The projection apparatus projects the display interface onto a surface in the vehicle cabin, providing visual feedback to the user without requiring them to look at a traditional screen or dashboard display.
Solution Approach 2:
The display interface is projected from a two-dimensional screen into three-dimensional space within the vehicle cabin. The projection can be displayed on various surfaces (windshield, dashboard, ceiling) at different positions and angles, allowing users to view the interface from multiple perspectives and locations.
2Measurement precision
If manual screen touching or button pressing is used, then measurement precision of user intent is improved, but ease of operation deteriorates due to safety concerns and user inconvenience
Solution Approach 1:
The mechanical interaction (touching screens or pressing buttons) is replaced with voice-based control. The control apparatus receives voice commands from the user, processes them, and executes the corresponding operations, eliminating the need for physical contact with control interfaces.
Solution Approach 2:
The projection apparatus serves as a visual intermediary that confirms voice command execution. Users can see the displayed interface and understand what actions are being performed without needing to physically interact with the system.
3Device complexity
If voice control without visual feedback is used, then device complexity is reduced, but reliability deteriorates due to inability to detect control errors
Solution Approach 1:
The system implements visual feedback by projecting the display interface that shows the current state and execution status of voice commands. Users can see what commands are being processed and verify that the system is responding correctly, enabling them to detect and correct errors.

AI summary
The present invention provides in-vehicle projection system and control method therefor, and vehicle. The in-vehicle projection system includes: a control apparatus that receives a command from a user, acquire a display interface related to operation regarding the command, and determine position of the user in vehicle according to the command; and a projection apparatus that projects the display interface to predetermined region in the vehicle corresponding to the position of the user. The control apparatus starts to execute the operation regarding the command from the user, and the display interface displays process of the control apparatus executing the operation regarding the command from the user. Accordingly, by projecting the display interface related to the operation regarding the command issued by the user to suitable region visible to the user, the user intuitively sees execution process of the command, which increases the interestingness and improves user experience.
