Solution Overview
Problem
Users find it cumbersome to operate buttons or switches on writing instruments to initiate communication with communication terminals, making the process inconvenient.
Innovation Solution
A writing instrument equipped with sensors that detect motion and transmit signals to an electronic device, allowing the device to execute predetermined operations without user intervention, such as starting communication or displaying notifications, using a Bluetooth Low Energy beacon signal when the cap is removed or specific motions are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button or switch operation is required to initiate communication, then the communication function is reliable, but the ease of operation deteriorates
Solution Approach 1:
The writing instrument automatically detects cap removal through sensor 42 and transmits beacon signals without requiring user intervention. The system serves itself by autonomously initiating communication based on detected motion, eliminating the need for manual button operations while maintaining reliable communication functionality
Solution Approach 2:
The patent replaces mechanical button/switch operations with sensor-based detection systems. Sensor 42 detects cap removal motion and triggers automatic beacon signal transmission, substituting the mechanical interaction paradigm with an automated sensing and response system that improves ease of operation
2Ease of operation
If automatic communication initiation is implemented, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent extracts the communication initiation logic from the user's manual operation and embeds it in the writing instrument's automated system. The sensor 42 and control logic are integrated into the instrument, allowing automatic beacon transmission when cap removal is detected, thereby improving ease of operation while containing complexity within the device
Solution Approach 2:
The writing instrument integrates multiple functions: writing capability, motion detection via sensor 42, and automatic communication initiation through beacon signals. This multi-functionality allows a single device to serve both traditional writing purposes and modern communication needs without requiring separate systems
3Ease of operation
If motion detection is used to trigger communication, then the ease of operation improves, but the reliability of operation intent detection may worsen
Solution Approach 1:
The system performs preliminary detection of cap removal motion through sensor 42 before initiating communication. By detecting the specific motion pattern of cap removal and confirming it as the trigger condition, the system ensures that communication is initiated only when the intended action is clearly detected, maintaining reliability while improving ease of operation

AI summary
ObjectTo provide an information processing system and the like which enables a user to start communication between a writing instrument and an electronic device with a simple operation.SolutionAn information processing system includes a writing instrument having a communication function and an electronic device that communicates with the writing instrument. The writing instrument includes a sensor that detects a motion, a determination unit that determines whether the motion detected by the sensor is a predetermined motion, and a transmission unit that transmits a predetermined signal to the electronic device. The transmission unit transmits, to the electronic device, the predetermined signal for causing the electronic device to execute a first operation without an operation by a user, when determining that the motion detected by the sensor is the predetermined motion.
