How accurately can you judge distance without measuring it? ArchiTest is a fun game that makes spatial estimation a physical challenge.
Created by two architects, the project explores how people intuitively perceive and estimate distance in space. At the center of the setup, an OLED display shows a number representing a target distance. Two players stand on opposite sides and move their paddles, relying purely on judgment to place the paddle at what they believe is the correct distance.
A concealed ultrasonic sensor on each side measures how far the paddle actually is from the fixed reference point. Once both players commit, the system compares their distances to the target value. The player whose paddle is closest wins the round, indicated by a light turning on along their LED ring. The game runs for five rounds, with each round contributing to the final score.
ArchiTest was built using a single Arduino Uno, two ultrasonic sensors, an OLED display, and two LED rings. The project intentionally uses minimal components to keep the interaction legible and immediate.
Through building ArchiTest, the team learned how to organize hardware components, read and calibrate sensor data, and assemble sensors and actuators into a game that highlights human spatial intuition instead of precise measurement.
