Vehicle Navigation Speech Recognition Text Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems in vehicles are limited in their ability to facilitate safe and efficient communication for drivers, as they often require manual textual input, which can distract the driver and impair their ability to operate the vehicle safely.
Innovation Solution
A vehicle navigation system that utilizes speech recognition to generate and send text messages, allowing users to control the system audibly through a microphone, which transforms voice inputs into text messages for transmission, and provides visual or audible confirmation before sending, using a combination of speech recognition elements, Bluetooth, and wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual textual input is used for communication in a navigation system, then communication capability is provided, but driver safety deteriorates due to distraction
Solution Approach 1:
The patent replaces manual mechanical text input with speech recognition technology. The speech recognition element captures verbal commands from the driver and converts them into text messages, eliminating the need for manual keyboard or touchscreen input. This substitution maintains communication capability while removing the distracting manual operation that compromises driver safety.
2Reliability
If speech recognition is used to generate text messages, then driver safety is maintained, but communication functionality is limited compared to manual input
Solution Approach 1:
The patent implements a multi-functional communication system that supports multiple message formats (sentence-by-sentence, word-by-word, letter-by-letter) and delivery methods (visual display, audible output). The speech recognition element is integrated with the navigation system's existing communication capabilities, allowing it to function as both a navigation device and a comprehensive messaging system, thereby enhancing communication functionality while maintaining driver safety.
3Measurement precision
If manual editing of messages is required, then message accuracy is improved, but driver distraction increases
Solution Approach 1:
The patent incorporates a feedback mechanism where the generated text message is displayed or audibly presented to the driver for verification before transmission. The driver can review the accuracy of the speech-to-text conversion and confirm or correct the message using minimal input (such as pressing a confirmation button or making minor adjustments). This feedback loop ensures message accuracy while requiring minimal driver interaction, thus reducing distraction compared to full manual editing.
Data Source
AI summary
A vehicle navigation system may send and receive communications, such as text messages. Speech recognition may generate a text message without affecting a driver's control of the vehicle. A user may audibly control the navigation system and generate a text message through a speech recognition element. A microphone may record a user's voice, which is then transformed into a text message for transmission. The message may be recorded sentence-by-sentence, word-by-word, or letter-by-letter. The recorded text message may be visually or audibly presented to the user before transmission.
