Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective solutions for enabling remote collaboration on hand-drawn images, particularly in business, education, and government settings, where participants at different locations cannot view hand-drawn notes or figures on surfaces like dry erase boards or flip charts.
Innovation Solution
A system using a specialized wand that tracks its motion relative to a surface, allowing physical markings to be cloned and displayed remotely, utilizing wireless communication and trilateration techniques to identify the wand's position and orientation, and project the markings onto a virtual plane for remote viewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If hand-drawn images are created on physical surfaces like dry erase boards or flip charts, then the presenter can easily jot notes and figures, but collaborators at remote locations cannot view these hand-drawn images
Solution Approach 1:
The patent creates digital copies of hand-drawn images by tracking the wand's motion and generating corresponding digital representations. The system captures the physical drawing actions and replicates them as digital images that can be transmitted and viewed remotely, solving the visibility problem without requiring complex real-time streaming of physical surfaces
Solution Approach 2:
The patent introduces a wand as an intermediary device between the physical drawing surface and the digital display. The wand tracks position and orientation to mediate between the physical hand-drawn images and their digital representations, enabling remote viewing while maintaining simplicity of the drawing process
2Productivity
If a system is implemented to track and clone hand-drawn images in real-time, then remote collaboration is enabled, but the device complexity and implementation cost increase
Solution Approach 1:
The wand serves multiple functions: it acts as a physical marking device for drawing, a positioning sensor for tracking motion, and a communication interface for transmitting drawing data. This multi-functionality reduces the need for separate specialized devices, thereby reducing overall system complexity while maintaining remote collaboration capabilities
Solution Approach 2:
The system automatically tracks the wand's position and orientation and generates digital images of hand-drawn content without requiring manual intervention. The automatic cloning and transmission processes eliminate the need for separate scanning or photographing steps, reducing operational complexity while improving collaboration efficiency

AI summary
A method for cloning hand drawn images includes identifying, within an environment, a position of a wand with respect to each of a first plurality of user selected physical points. A virtual plane identified by the first plurality of points is defined. The virtual plane corresponds to a first marking surface. An electronic page is associated with the first virtual plane. A motion of the wand is tracked. The motion corresponds to a use of the wand to draw a first mark on the first marking surface. A path traced across the first virtual plane is identified. The path is defined by the tracked motion. The electronic page is updated to include a digital image representative of the path. The digital image is a clone of the mark.
