Communication Terminal Touch Panel Area Segmentation for Call Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a call is received during a mouse operation on a portable phone connected to an external display device, users often unintentionally respond to the call notification due to being focused on the external screen, leading to unintended mouse operation cessation.
Innovation Solution
A communication terminal with a touch panel featuring distinct operation areas for position designation and response, a detecting unit for event notification, and a control unit that differentiates between these areas to prevent incorrect operations by performing appropriate actions based on the detected event.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable phone is used as a mouse for external display device while a call is received, then the user can continue mouse operation, but the user may unintentionally respond to the call notification due to being focused on the external screen
Solution Approach 1:
The touch panel is divided into distinct operation areas: a first operation area for mouse operations and a second operation area for call response operations. This segmentation allows the system to differentiate between intended mouse operations and call response operations, preventing unintentional call acceptance while maintaining smooth mouse operation continuity on the external display device.
2Adaptability or versatility
If YES indication and NO indication are popped up on the portable phone screen during mouse operation, then the user can respond to the call, but the user is likely to be unaware of the pop-up since the user is watching the external display device screen
Solution Approach 1:
The notification interface is designed with different visual characteristics for different operation areas. The first operation area maintains mouse operation functionality, while the second operation area displays call notification indicators with distinct visual properties. This local quality differentiation ensures users can perceive notifications without disrupting the mouse operation experience on the external display.
3Reliability
If the touch panel receives contact operation in the second operation area during call notification, then the call response is processed, but the mouse operation stops and unintended operation is performed
Solution Approach 1:
The control unit acts as an intermediary that receives contact operation information from the touch panel, determines whether the contact occurred in the first or second operation area, and routes the operation accordingly. When a contact is detected in the second operation area during an active call notification, the control unit processes the call response while preventing interruption of the mouse operation, thus maintaining productivity without sacrificing reliability.

AI summary
A communication terminal includes: a touch panel, which receives a contact operation and outputs position information representing the contact position, and which includes a first operation area configured to receive a position designating operation and a second operation area configured to receive a response operation to respond to an event occurring according to an execution of another function; a control unit, which determines whether the position information represents the first operation area or the second operation area, wherein, in a case where the position information represents the first operation area, the control unit outputs the received position information to the transmitting unit, and wherein, in a case where the position information represents the second operation area and the notification signal is received, the control unit controls to perform a process corresponding to a notification signal.
