Principle 1 ) Use vibration• Use vibration as an alarm• Use vibration to feel the music
The clock sends vibrations to the fingertip of the user to give an alarm
The clock vibrates under the pillow to give an alarm
Wristband type
The vibrators are attached around the body of the user to warn when danger appears
Principle 1 ) Use vibration• Use vibration as an alarm• Use vibration to feel the music
Wristband type
Principle 1 ) Use vibration• Use vibration as an alarm• Use vibration to feel the music
The vibrators are attached around the body of the user to warn him/her when danger appears

Principle 1 ) Use vibration• Use vibration as an alarm• Use vibration to feel the music
Vibration chair
Principle 1 ) Use vibration• Use vibration as an alarm• Use vibration to feel the music
Hugging the vibrating device enables the user to feel the music
Principle 2 ) Use flashing light• Use flashing light as an alarm
Doorbell
Mail delivery
Principle 3 ) Use icon• Use icon to visualize the auditory information
Informations are visualized with icons
Principle 4 ) Use waveform• Use waveform to express the direction, loudness and wave pattern of sound.
Sound is presented through the waveform
Principle 4 ) Use waveform• Use waveform to express the direction, loudness and wave pattern of sound.
Voice is converted into a waveform
By comparing the waveforms, a child can practice correctly modulated pronunciations
Principle 5 ) Use bone conduction• Use bone conduction to directly transmit the sound to the inner ear
Telephone type
Earphones type
Principle 5 ) Use bone conduction• Use bone conduction to directly transmit the sound to the inner ear
Headphones type
Principle 6 ) Use the tactile stimuli• Convert sound to tactile stimuli
The device enables the deaf to feel the music through tactile stimuli
