YataLogic’s analysis
The key point of this case
Turns multiple numerical readings into colors and expressions that make the current state easier to judge.
From official information
Officially documented uses
- Dai Pichon-kun is a large LED sign that represents air conditions based on temperature and humidity using nine “air-color Pichon-kun” colors.
- The official explanation explicitly describes visualizing hard-to-see air conditions through color, expressions and sound-symbolic words.
- New displays introduced in August 2026 address heatstroke risks at temperatures of 40°C or above and in high humidity.
- The stated aim is to encourage early heatstroke precautions such as hydration, air-conditioning use and reconsidering outdoor activities.
YataLogic’s view of the challenge
Which challenge does this relate to?
Even when temperature and humidity are visible as numbers, it can be difficult to intuitively judge their combined effect on comfort or physical strain.
Roles identified by YataLogic
