Electronic Device Character Input During Telephone Call
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices cannot execute functions using characters inputted during a telephone call, limiting user convenience and functionality.
Innovation Solution
An electronic device with a communication unit, input unit, and control unit that allows character input and execution of predetermined functions, such as search functions, during a call, with the ability to convert voice recognition and display results on both devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If character input function is available during telephone call, then user convenience and functionality are improved, but system complexity increases
Solution Approach 1:
The control unit is designed to perform multiple functions: it manages both telephone call operations and character input processing within a single integrated system. During a call, the control unit can switch between voice communication mode and text input mode, allowing the device to execute functions like searching using input characters without requiring separate dedicated systems for each function.
2Productivity
If search function is executed during call using input character, then productivity is improved, but loss of time increases due to context switching
Solution Approach 1:
The system maintains the input character in memory during the call state, preparing it in advance for potential search operations. When a search function is selected, the pre-held character is immediately used without requiring re-input or additional processing time, thus minimizing context switching delays while enabling quick information retrieval during calls.

AI summary
There is provided an electronic device that can execute a function using characters inputted during a telephone call, and a control method and a control program thereof. An application control unit inputs a character as an input character using an input control unit in a state where a call with a predetermined communication counterpart is continuing using a communication unit. When a predetermined function is selected after the input character is inputted with the input control unit, the application control unit executes a predetermined function in a state where the input character is inputted.
