2. 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

3. 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 when danger appears Wristband type

4. 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 Wristband type

5. Principle 1 ) Use vibration • Use vibration as an alarm • Use vibration to feel the music The devices translate sound into a series of vibrations Vibration chair

6. 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

7. Principle 2 ) Use flashing light • Use flashing light as an alarm Doorbell Mail delivery

8. Principle 3 ) Use icon • Use icon to visualize the auditory information Informations are visualized with icons

9. Principle 4 ) Use waveform • Use waveform to express the direction, loudness and wave pattern of sound. Sound is presented through the waveform

10. Principle 4 ) Use waveform • Use waveform to express the direction, loudness and wave pattern of sound. Voice is converted into a waveform By comparingthe waveforms, a child can practice correctly modulated pronunciations

11. Principle 5 ) Use bone conduction • Use bone conduction to directly transmit the sound to the inner ear Telephone type Earphones type

12. Principle 5 ) Use bone conduction • Use bone conduction to directly transmit the sound to the inner ear Headphones type

13. Principle 6 ) Use the tactile stimuli • Convert sound to tactile stimuli The device enables the deaf to feel the music throughtactile stimuli

14. Principle 7 ) Use the sign language • Translate between speech and sign language Sign language  Speech

15. Principle 7 ) Use the sign language • Translate between speech and sign language Sign language  Speech Necklace type

16. Principle 7 ) Use the sign language • Translate between speech and sign language Necklace type Stand type

17. Principle 8 ) Provide caption • Provide caption at the bottom of the screen • Provide caption below the line of sight Caption can be provided bythe microchip

18. Principle 8 ) Provide caption • Provide caption at the bottom of the screen • Provide caption below the line of sight Caption can be provided below the line of sight

19. Principle 9) Convert text to speech • Read typed text materials with voice Typed text  Voice

20. Principle 10 ) Convert gesture to text • Convert gestures into texts through device Gesture  Text

21. Principle 11 ) Use video call • Use video call to communicate with sign languages Video call services areprovided withATM for deaf Most phones have video call functions
