Touch Memo Input During Hands-Free Mobile Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals lack an efficient method to record and transmit memo information during hands-free communication, requiring users to write with a pen and paper, which is inconvenient and not suitable for hands-free operations.
Innovation Solution
A method and apparatus that activates a touch panel in a hands-free communication state, allowing users to input and store memos via touch input, which can be transmitted to subscribers during or after communication, using a capacitive or EMR touch panel, and converting the input into text or image files for transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user writes memo information using a pen and paper during hands-free communication, then the memo can be recorded, but the operation becomes inconvenient and not suitable for hands-free operations
Solution Approach 1:
The patent replaces the mechanical pen-and-paper writing system with an electronic touch panel input system. The touch panel allows users to input memo information by touching the display screen during hands-free communication, eliminating the need for physical writing instruments and paper, thus making the operation convenient while maintaining full memo recording capability
Solution Approach 2:
The patent creates a digital copy of the memo input process by displaying a virtual keypad and memo input interface on the touch panel. Instead of writing on paper, users interact with a digital representation of the memo system through touch input, which is then converted into stored text data, preserving the memo functionality while enabling hands-free operation convenience
2Adaptability or versatility
If the touch panel is activated during hands-free communication, then touch memo input is enabled, but the device complexity increases
Solution Approach 1:
The patent makes the touch panel serve multiple functions: it acts as both the communication interface display and the memo input device. The same touch panel used for displaying communication information is also used for entering memo data, eliminating the need for separate input devices and reducing overall system complexity while enhancing adaptability
Solution Approach 2:
The patent merges the communication display function and memo input function into a single integrated interface. The touch panel simultaneously displays communication status and provides the keypad interface for memo entry, combining what would traditionally be separate functions into one unified system, thereby reducing complexity while increasing versatility
3Speed
If memo information is transmitted during communication, then the information can be shared in real-time, but the transmission method and recipient selection becomes complex
Solution Approach 1:
The patent allows users to pre-select communication recipients and transmission methods before memo input. The system stores contact information and communication preferences in advance, so when a user wants to transmit a memo during communication, the system automatically presents pre-configured options, reducing the complexity of real-time decision-making while enabling fast transmission
Solution Approach 2:
The patent implements automatic recipient and method selection based on communication context. When a user initiates memo transmission during an active call, the system automatically identifies the current communication partner as the recipient and selects the appropriate transmission channel, eliminating the need for manual configuration and simplifying the transmission process while maintaining real-time capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to record and transmit memo information seamlessly during hands-free communication, enhancing convenience and usability by allowing touch input and storage, with options for transmission via various methods like SMS, MMS, or email, maintaining the communication state and allowing selection of recipients.
Implementation Method 1
the touch panel of the related art uses a capacitive type and a resistive type that senses a touch from a user's finger
Implementation Method 2
electro magnetic resonance (EMR) technology of Wacom company senses a pen input through a resonance between a flexible printed circuit board (FPCB) and an EMR exclusive pen

AI summary
A method of processing a memo while performing communication in a terminal includes: performing the communication; activating a touch memo input mode in response to a predetermined event occurring; displaying a touch memo on a display device in a communication state and performing a communication service, in response to receiving an input of the touch memo; and transmitting the touch memo to a communicating subscriber and maintaining the communication state after a request for transmission of the touch memo is input.
