Life Enhancing Technology Lab

Seoul National University


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


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


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


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


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 comparingthe 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 throughtactile stimuli


Principle 7 ) Use the sign language

  • Translate between speech and sign language

Sign language  Speech


Principle 7 ) Use the sign language

  • Translate between speech and sign language

Sign language  Speech

Necklace type


Principle 7 ) Use the sign language

  • Translate between speech and sign language

Necklace type

Stand type


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


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


Principle 9) Convert text to speech

  • Read typed text materials with voice

Typed text  Voice


Principle 10 ) Convert gesture to text

  • Convert gestures into texts through device

Gesture  Text


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
