GREEDYEMON
Interactive Toy For Collecting Coins
About
Greedyemon is an interactive installation designed for collecting tips. I create this new tip pot to make the tipping process more engaging and fun. When customers come close to it, the cat will shake his hands to attract customers' attention. When customers throw coins into its head, the cat will rotate his head and begin to smile. Then, he will be sad again.
Making Process
Problem 1: How to make the cat detect the coin?
Pressure Sensor? — ❌ Not sensible enough
Infrared LED Emitter and Detector? — ❌ Have no time to get them and may need to Arduino
Infrared Obstacle Detection? — ✅ It is sensitive and convenient!!!
Problem 1: How to avoid the wall of the box reflecting the infrared ray?
Hmmm…It reminds me of the knowledge of Physics in high school:
Black color has the most absorbing capacity of light. I test it with black paper, it works well!!!!😂So I paint it all black!
User Test
Takeaways from the user test:
Most people don’t realize that the cat is interactive
People use the card the most in the stores I chose
The cartoon character is not as popular as I assumed in US
Iteration
In the next version, I would like to make it more engaging with the people. I need to make people understand that this is a smart and interactive cat. Also, I want to apply some effects that are familiar to the people here, which reminds me of the fortune cat. To make it more interactive, I use the human body infrared sensor. When people come close to the cat, it will shake its arm.
