Yun Hohyeon, <Echo Eye>, Physical Computing, 2026
This small interactive object responds by raising or lowering its head according to the viewer's distance.
A VL53L0X distance sensor detects the viewer's approach, prompting a servo motor to slowly lift the head while 25 single-color LEDs arranged as an eye illuminate sequentially, creating the effect of the eye opening. A WS2812 LED positioned at the center functions as the pupil, adding a sense of vitality through changes in color and brightness. As the viewer moves away, the LEDs switch off sequentially from top to bottom, and the servo motor gradually lowers the head, returning the object to a dormant state.
