This research introduces an approach for delivering tactile sensations to the forehead, specifically targeting the low-frequency band using a compact linear resonant actuator. Utilizing the absence of Pacinian corpuscles, which typically detect vibrations around 200 Hz on the forehead, we employed amplitude modulation to compensate for the challenge of the limited frequency range of linear resonant actuators. The amplitude modulation was achieved by around 200-Hz carrier wave around the actuator’s resonant frequency. Through two experiments, we evaluated the effectiveness of this modulation in conveying low-frequency vibrations (Experiment 1) and assessed the perceptual quality of the vibrations (Experiment 2) experienced on the forehead. Our findings indicate that participants could clearly feel the original low-frequency vibration on the forehead compared to other body locations.
