This paper presents a haptic display with the audio-based vibrotactile feedback to enhance the immersive feeling of the user who interacts with the multimedia content. The newly developed display has two main features – an automatic transformation algorithm and a vibrotactile actuator. The proposed algorithm automatically transforms auditory signals into vibrotactile patterns in real-time by extracting principal frequencies from the audio sequence and superposing vibration waves. The actuator was designed based on the structure of the voice coil linear motor to operate effectively over a wide range of vibration frequencies. Experiments were carried out to evaluate characteristics of the implemented system and demonstrate the effectiveness of the proposed approach.
