PTT Button and Channel Knob for Voice Input into Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public-safety personnel face inefficiencies in inputting voice data into applications, as existing systems require manual typing or complex navigation, which increases the time needed for information entry.
Innovation Solution
A method and apparatus that utilize a push-to-talk (PTT) button and a channel-change knob on a radio to collect voice input, converting it into text or recording it for direct input into selected applications, allowing seamless switching between talkgroups and applications, thereby streamlining the data entry process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual typing or complex navigation is used to input voice data into applications, then input accuracy can be maintained, but the time required for information entry increases
Solution Approach 1:
The PTT button and talkgroup selector are extended to serve dual purposes: traditional radio communication functions and application control functions. The PTT button now triggers both talkgroup transmission and application voice input, while the talkgroup selector also cycles through applications. This multi-functionality eliminates the need for separate controls for each mode, significantly reducing the time required to input information into applications while maintaining ease of operation through familiar controls.
Solution Approach 2:
The patent combines the radio communication interface with application control capabilities into a unified system. The same physical controls (PTT button, talkgroup selector) and the same audio output device (speaker) are used for both traditional talkgroup communication and application voice input. This merging of functions allows users to switch between communication modes and application input modes without changing controls or procedures, thereby reducing operational time and complexity.
2Productivity
If PTT button and talkgroup selector are used to control voice input into applications, then information entry time is reduced, but system complexity increases
Solution Approach 1:
The system implements multi-functionality by enabling the PTT button and talkgroup selector to operate in multiple modes: traditional radio communication mode and application control mode. The control logic automatically determines the current mode based on system state, and the same physical controls perform different functions accordingly. This approach increases productivity by providing rapid access to applications while managing complexity through context-aware control routing rather than adding separate controls for each function.
Solution Approach 2:
The system employs self-service mechanisms where the control logic automatically manages the switching between talkgroup communication and application input modes without requiring user intervention. When the PTT button is pressed or the talkgroup selector is rotated, the system autonomously determines whether to activate radio transmission or application voice input based on the current selected mode, thereby improving productivity while keeping the user interface simple and avoiding the complexity of manual mode switching.
3Ease of operation
If the same controls are used for both talkgroup selection and application selection, then ease of operation is improved, but the difficulty of detecting and measuring the selected mode increases
Solution Approach 1:
The system implements feedback mechanisms to clearly indicate the current operational mode to the user. The display provides visual feedback showing whether the system is in talkgroup communication mode or application input mode. Additionally, the speaker provides auditory feedback by playing back the selected talkgroup or application identifier, confirming the current mode to the user. This feedback ensures that users can easily detect the current mode despite using the same physical controls for both functions, thereby maintaining ease of operation while resolving the detection difficulty.
Data Source
AI summary
A method and apparatus for inputting voice into an application is provided herein. During operation a “channel-change” knob (sometimes referred to as a selector knob) on a radio will be utilized to cycle between talkgroups/channels for over-the-air voice transmission. Additionally, the channel-change knob on the radio will be used to cycle between applications stored on the radio. A push-to-talk button on the radio will serve as a trigger to collect voice input for a selected talkgroup for over-the-air transmission when a talkgroup is selected, and will also serve as a trigger to collect voice input for an application when the application is selected.
