Mobile Phone PTT Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phones with Push-to-Talk (PTT) functions do not effectively manage user interactions during PTT calls, failing to seamlessly integrate information about PTT calls with other functions, leading to user confusion and lack of visibility into call participants and status.
Innovation Solution
A mobile phone system that includes an operation receiving module and a display control module to receive user operations and display both PTT call information and information related to other functions, allowing for concurrent display of PTT call participants and status alongside other application screens, using a priority list to manage display objects and update pictograms accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile phone displays only PTT call information during a PTT call, then the call status is clearly visible, but the user cannot access or view information from other applications
Solution Approach 1:
The display screen is segmented into multiple regions: a first region dedicated to displaying PTT call information (participants, status) and a second region for displaying information from other applications. This segmentation allows both PTT call information and other application information to be displayed simultaneously without interference, resolving the contradiction between maintaining call visibility and accessing other applications.
Solution Approach 2:
The PTT call information display is nested within the overall display system alongside other application information. The first display region containing PTT information is embedded within the same screen space as the second region for other applications, allowing hierarchical coexistence of different information layers while maintaining access to both.
2Adaptability or versatility
If the mobile phone displays information from other applications during a PTT call, then the user can access other functions, but the PTT call information becomes less visible or inaccessible
Solution Approach 1:
The display is divided into distinct regions where the first region maintains PTT call information visibility while the second region displays other application information. This spatial segmentation ensures that PTT information remains continuously visible even when other applications are active, preventing information loss while enabling application access.
Solution Approach 2:
The solution transitions from a single-dimensional display (either PTT or other apps) to a two-dimensional display layout with multiple regions. By adding the spatial dimension of display regions, the system can simultaneously present PTT call information and other application information without one obscuring the other.
3Ease of operation
If the mobile phone switches between PTT call display and other application displays, then full screen access is achieved, but user confusion increases and continuity is lost
Solution Approach 1:
The display screen is permanently segmented into a first region for PTT information and a second region for other applications, eliminating the need to switch between full-screen displays. This segmentation provides continuous access to both information types simultaneously, reducing user confusion while maintaining ease of operation.
Solution Approach 2:
The display regions are pre-configured and continuously maintained during the PTT call, with the first region always showing PTT information and the second region showing other application information. This preliminary setup eliminates the need for users to perform switching actions, reducing operational complexity while maintaining full information accessibility.

AI summary
A mobile phone provided with a push-to-talk function and methods for operating a mobile phone provided with a push-to-talk function are disclosed. An operation receiving module is configured to receive a user operation. A display control module is configured to cause a display module to display both first information relevant to a push-to-talk call and second information relevant to a function other than the push-to-talk, if the user operation for executing the function other than the push-to-talk is received during the push-to-talk call.
