PoC Terminal Marker Overlay for Group Conversation Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PoC portable terminals lack the ability to edit or add information on their screens during group telephone conversations, limiting user interaction and communication.
Innovation Solution
A PoC system with a portable terminal equipped with a radio part for receiving common image data, a display part for showing markers, and an input part for controlling marker display, allowing users to add pointers or markers on the screen when speaking, which are then transmitted to other terminals in the group, enabling dynamic screen editing and information addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional PoC portable terminals are used for group telephone conversations, then the basic communication function is maintained, but the ability to edit or add information on display screens is lost
Solution Approach 1:
The patent introduces a marker as an intermediary element between the user's input and the display screen. The marker serves as a temporary annotation that can be added to the common image displayed during group conversations, allowing users to highlight or emphasize specific elements without permanently modifying the original display content. This intermediary approach enables screen editing functionality while maintaining the simplicity of the base system.
Solution Approach 2:
The patent implements dynamic marker display where markers can be added, removed, and modified during the ongoing group telephone conversation. The marker display is not static but can be activated and deactivated based on user input and conversation needs. This dynamic capability allows the system to adapt to different communication scenarios without requiring permanent structural changes to the terminal hardware.
2Ease of operation
If markers are displayed on the screen during group conversations, then user interaction and communication are enhanced, but the display complexity increases
Solution Approach 1:
The patent segments the display into two distinct components: the original common image displayed during the group conversation and the overlay marker added by the user. This segmentation allows the marker to be independently controlled and managed without affecting the underlying conversation display. The marker can be positioned, sized, and styled separately from the common image, simplifying the display management while enhancing user interaction capabilities.
Solution Approach 2:
The patent utilizes color changes as a primary mechanism for displaying markers. By using distinct colors to represent different types of markers or user inputs, the system provides clear visual feedback without requiring complex graphical interfaces. The color-coded marker system simplifies display complexity while maintaining high user interaction effectiveness, as users can quickly identify and respond to different marker types based on their color coding.

AI summary
The present invention provides a PoC portable terminal capable of performing edit and information addition on a display screen on which screen information relating to a group telephone conversation is displayed. When a push button of a key operation part 15 is pushed down, a portable terminal 1 becomes a master side. The portable terminal 1 displays pointer information of a marker, which is outputted by a pointing device part 18, on a display part 16. The portable terminal 1 transmits the pointer information from a radio part 14 to a PoC server. The PoC server sends the pointer information from the portable terminal 1 to other users' portable terminals in a group. If the pointer is moved, then the portable terminal 1 as a master side repeats the aforementioned processes.
