Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic conference systems require cumbersome connections between user terminal apparatuses, lacking a natural feature similar to actual pen input, which hinders intuitive handwriting input during electronic conferences.
Innovation Solution
A digital pen system that combines a first handwriting unit for ink input on paper and a second handwriting unit using electromagnetic resonance for touch sensing, allowing simultaneous ink and digital input, with an electronic conference apparatus that senses and processes handwriting information for display and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital pen system is implemented for electronic conferences, then handwriting input capability is improved, but device complexity increases
Solution Approach 1:
The digital pen system is divided into separate functional modules: a pen module containing sensing elements, a terminal apparatus for processing, and an external display device. This segmentation allows each component to be optimized independently while maintaining overall system functionality, reducing the complexity burden on any single device.
Solution Approach 2:
The digital pen is designed to perform multiple functions: it can detect touch input, recognize handwriting, and transmit data wirelessly. The terminal apparatus also serves multiple purposes including receiving pen data, processing handwriting recognition, and managing conference communications. This multi-functionality reduces the number of separate devices needed.
2Adaptability or versatility
If multiple user terminal apparatuses are connected for electronic conferences, then conference functionality is improved, but ease of operation deteriorates due to cumbersome connections
Solution Approach 1:
The patent replaces physical connection mechanisms (cables, ports, and manual pairing) with wireless communication technology. The digital pen and terminal apparatus communicate via wireless signals, eliminating the need for physical connections between multiple devices during conferences, thereby simplifying setup and improving ease of operation.
3Measurement precision
If electromagnetic resonance sensing is used in the digital pen, then touch input sensitivity is improved, but energy consumption increases
Solution Approach 1:
The electromagnetic resonance sensing in the digital pen operates periodically rather than continuously. The pen emits electromagnetic signals at specific intervals to detect touch input, allowing it to maintain high sensitivity when needed while consuming minimal energy during idle periods. This periodic operation balances measurement precision with energy conservation.

AI summary
An electronic conference apparatus, a method for controlling the same, and a digital pen are provided. The electronic conference apparatus includes a sensor configured to sense a touch point of a digital pen through first hand writer during a period in which handwriting is input to a recording medium through second hand writer. The electronic conference apparatus further includes a controller configured to generate handwriting information based on the sensed touch point, and a communicator configured to transmit the handwriting information.
