How do you make advertising captivating? Sensors.
Two recent examples of real-world interactive ads show how sensor-rigged displays can engage and delight audiences.
A subway ad for Swedish hair care products maker Apotek Hjärtat's Apolosophy shows a woman whose long hair blows in the wind when subway trains enter and exit the station. It achieves this through digital screens equipped with ultrasonic sensors that monitor when trains enter and exit the station.
