Voice-Controlled Display Rotation for Sound Source Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent voice assistant products can only provide information through voice mode and are not suitable for presenting image or video information, nor can they directly provide manifest information like lists of contacts, calendars, or schedules through voice alone.
Innovation Solution
A voice control system that includes a voice control device connected to a network server and remote electronic devices with displays, enabling the transmission of text, voice, and image information, and using image recognition to adjust the display orientation based on user presence and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice mode is used to provide information, then the device can operate with simple output capabilities, but it cannot present image information or video information effectively
Solution Approach 1:
The voice control device is designed to perform multiple functions: it can provide information through voice mode, display image information on a display unit, and show video information through a video output unit. This multi-functionality allows the device to adapt to different information presentation needs without requiring separate dedicated devices, thereby resolving the contradiction between versatility and complexity by integrating multiple capabilities into a single unified system.
2Adaptability or versatility
If voice mode is used to provide manifest information, then the device maintains simple operation, but it is not suitable for presenting lists of contacts, calendars, or schedules
Solution Approach 1:
The device dynamically selects the appropriate output mode based on the type of information being presented. For manifest information such as contacts, calendars, and schedules, the system automatically switches to visual display modes (display unit or video output unit) rather than voice mode, as these types of information are more effectively conveyed visually. This dynamic adaptation allows the device to handle different information types optimally without requiring a permanently complex output system.
3Ease of operation
If the display rotates and tilts to follow the user, then user interaction is improved, but the device requires additional drive units and control mechanisms
Solution Approach 1:
The display unit is equipped with automatic rotation and tilting capabilities driven by drive units that respond to user presence detection. Instead of requiring manual adjustment by the user, the system automatically adjusts the display orientation to follow and accommodate the user's position and viewing angle. This self-service approach improves ease of operation by eliminating the need for manual intervention, while the automation is achieved through integrated drive units that are part of the overall system design rather than separate complex mechanisms.
Data Source
AI summary
A voice control device includes a microphone module, a voice encoding module, a display and a processing unit. The voice encoding module is electrically connected to the microphone module. The processing unit is electrically connected to the voice encoding module and the display. The microphone module receives a voice signal and transmits the received voice signal to the voice encoding module. One of the voice encoding module and the processing unit analyzes and processes the voice signal to determine a sound source direction of the voice signal and obtains response information according to the voice signal. The processing unit controls the display to rotate to the sound source direction and transmits the response information to the display for displaying the response information.
