Electronic Whiteboard Event Identification Using Device Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic whiteboards require users to perform complex settings, leading to usability issues and potential errors, particularly in determining whether stroke drawing by hand is available.
Innovation Solution
An electronic whiteboard system that includes a display unit, an event acquisition unit, an identifying unit, and a processing unit to automatically identify events such as stroke drawing, UI operations, and gesture operations based on device information, reducing the need for user settings and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic event identification is implemented, then usability is improved and user setting work is reduced, but device complexity increases
Solution Approach 1:
The electronic whiteboard automatically identifies event types using an identifying unit that references device information, enabling the system to serve itself without user intervention. This self-service mechanism reduces user setting work while improving usability, as the system autonomously determines whether stroke drawing by hand is available based on its own device characteristics
Solution Approach 2:
Device information is stored in advance in a storage unit, containing predetermined information about device characteristics. The identifying unit references this pre-stored information to automatically identify event types, eliminating the need for users to perform settings during operation. This preliminary preparation of device information enables automatic identification while managing system complexity
2Productivity
If multiple event types are automatically classified, then productivity is improved, but device complexity increases
Solution Approach 1:
The identifying unit segments event classification into distinct categories (stroke drawing, UI operations, gesture operations) based on device information. This segmentation allows the system to efficiently process different event types through appropriate handling units, improving productivity while managing complexity through structured classification
Solution Approach 2:
The identifying unit serves multiple functions by referencing device information to classify various event types (stroke drawing availability, UI operations, gesture operations). This multi-functional approach improves processing efficiency for different event scenarios while using a single unified identification mechanism, balancing productivity improvement with complexity management

AI summary
For the purpose of improving the usability of an electronic whiteboard in, for example, setting work by a user, an electronic whiteboard (2) of the present invention includes: an event acquisition unit (22, 24) configured to acquire information indicating an object coming into contact with a display (3, 115) and event information such as the coordinates of a contact location; an identifying unit (25, 38) configured to identify whether the contact object is an electronic pen (4) or a user's hand, and identify the event type, such as stroke drawing, UI operation, or gesture operation, from the coordinates of a contact location and the model name of an electronic whiteboard; and a processing unit (26, 27, 32) configured to perform processing on the event the type of which has been identified.
