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

The devices translate sound into a series of vibra-tions

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
