Perceived Magnitudes of Vibrations Transmitted Through Mobile Device

In this paper, we report the design and results of a psychophysical experiment wherein the perceived magnitudes of vibrations with various frequencies (20 ¿ 360 Hz) and amplitudes (6 ¿ 45 dB SL) transmitted to the hand through the mobile device were measured using the absolute magnitude estimation paradigm. For an apparatus, a mini vibration shaker on which a mock-up mobile device was mounted was used. We fitted a non-linear regression model to the measured data in order to obtain the perceived magnitudes in a large range of vibration frequency and amplitude. The findings of this paper can be used to assess the perceptual characteristics of vibrations from mobile device we experience everyday.
