Electronic Whiteboard with Imperfect Shapes for Informal Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic whiteboards in virtual environments are difficult to use for drawing, as they require indirect input devices like mice, leading to pixel-based, hard-to-edit drawings that distract from the meeting flow, and pre-drawn shape tools focus on perfection rather than content.
Innovation Solution
An electronic whiteboard with a palette of imperfect shapes and text rendered in scripted fonts, using a randomizing function to simulate hand-drawn appearance, allowing users to quickly draw and add notes, vote, and record interactions, while snapshots and integration with minute-taking tools enhance meeting productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pre-drawn shape tools are used to enable accurate drawing, then manufacturing precision is improved, but ease of operation deteriorates as users spend time adjusting size and position to get perfect shapes
Solution Approach 1:
Instead of providing perfect pre-drawn shapes that require adjustment, the patent inverts the approach by deliberately creating imperfect, randomly varied shapes that require no adjustment. The randomization function introduces variability in size, position, and orientation, eliminating the need for users to spend time perfecting shapes while maintaining ease of use.
2Device complexity
If conventional input devices like mice are used for drawing, then device complexity is reduced, but ease of operation deteriorates as drawing becomes difficult and distracting
Solution Approach 1:
The patent replaces the mechanical mouse-drawing system with an automated computer-generated shape system. Instead of requiring users to manually draw shapes with a mouse, the system automatically generates shapes with randomized properties, substituting the manual mechanical drawing process with an automated computational process that is much easier to operate.
3Device complexity
If pixel-based drawings are created, then device complexity is reduced, but ease of repair deteriorates as drawings become hard to edit
Solution Approach 1:
The patent changes the fundamental parameters of shape creation from fixed pixel-based rendering to parameter-driven generation with randomized properties. Each shape is defined by editable parameters (size, position, orientation, randomization factors) that can be easily modified, allowing users to adjust shapes by changing parameters rather than manually editing pixels, thus improving ease of repair while maintaining system simplicity.

AI summary
An electronic whiteboard may be used alone or in a virtual environment. The electronic whiteboard has a palate of tools that enable users to quickly draw shapes on the whiteboard. Rather than using perfectly drawn shapes, however, the palate renders shapes that are not quite perfect—rectangles that are not quite square, lines that are not quite straight—to prevent users from focusing on getting the drawings perfect. This lends an informal feeling to the resulting drawings to allow the drawings to more closely simulate how drawings would appear on a traditional whiteboard. Similarly, text is rendered using a scripted font rather than type font to make words on the whiteboard appear to be hand-written. The electronic whiteboard enables users to add notes and to vote on objects. Automatic vote counting and note management is provided. Use of the whiteboard may be recorded to enable sessions to be replayed and snapshots to be obtained.
