Solution Overview
Problem
Thermal imaging devices are not effectively utilized to visualize and interact with heat energy patterns in dynamic environments, limiting their application in artistic and creative fields.
Innovation Solution
An interactive thermographic display system combining a thermal camera and a visible light projector, which captures and projects live thermal video onto a projection screen, allowing users to visualize and 'paint' with their body heat, and an interactive thermographic printing system that colorizes and prints heat patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If thermal cameras are used to capture heat patterns, then heat energy patterns can be detected, but the visualization and interaction with these patterns is not effective
Solution Approach 1:
A projection screen serves as an intermediary between the thermal camera's heat detection and human visual perception. The screen displays visible light representations of thermal patterns, making invisible heat energy visible and interactive for users.
Solution Approach 2:
The system applies color mapping to thermal data, transforming temperature variations into visible color patterns on the projection screen. This allows users to visually distinguish different heat patterns and interact with them intuitively.
2Productivity
If real-time thermal video is projected onto a screen, then heat patterns can be visualized in real time, but the system complexity increases
Solution Approach 1:
The system merges the thermal camera, projection screen, and visible light projector into an integrated interactive display system. This combination allows real-time thermal visualization while managing complexity through unified system architecture.
Solution Approach 2:
The projection screen serves multiple functions: it displays visible light representations of thermal patterns, enables user interaction through touch, and provides real-time feedback. This multi-functionality reduces the need for separate specialized components.
3Adaptability or versatility
If thermal imaging is applied in artistic settings, then creative applications expand, but the effectiveness of heat energy pattern visualization is limited
Solution Approach 1:
The system replaces direct thermal detection with optical projection. Instead of relying on thermal camera displays alone, it substitutes a visible light projection system that can artistically render heat patterns in ways more suitable for creative and artistic applications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables real-time visualization and recording of heat energy patterns, expanding the use of thermal imaging in artistic and interactive settings, providing a unique way to portray and preserve heat interactions.
Implementation Method 1
Thermal cameras are known in the art and are useful for capturing and visualizing temperature differences in an environment within the field of view of the camera
Implementation Method 2
When a person, or other warm body, comes into contact with the second side of the screen, the person's body heat warms the screen where it was touched

AI summary
Disclosed is an interactive thermographic presentation system and associated methods. The exemplary thermographic presentation system captures residual heat from human touch and/or breath on a surface over time and generates a visual representation of the captured heat pattern. The visual representation may be generated in real time using a visual light projector or stored for subsequent presentation, which may include generating a physical print of the visual representation. In one embodiment the system may be deployed as an art or science exhibit. In general, the system may be deployed in any setting in which individuals gather, including, but not limited to, art galleries, schools, science fairs, trade shows, music venues, dance clubs, restaurants, homes, and public spaces.
