Haptic Interface for Navigation of the Visually Impaired

2015-0302-03

predominance

・A haptic interface for navigation
・The generated centrifugal force using two eccentric weights is transmitted the user
・It is possible to indicate in any direction

background

・Navigation systems for the visually impaired 
・Not voice guided navigation
・Lightweight and small device

summary

・Control the position and velocity of the two eccentric weights in the haptic interface
    The rotational velocities of the weights are high in the travel  
    direction to provide higher centrifugal force. 
    Conversely, the velocities are lower on the opposite position.
・The generated centrifugal force is transmitted to the user

application/development

・Integration with the navigation system using information such as the IC tag of Braille block and smartphone GPS

material

  • A haptic interface for navigation of the visually impaired
  • Concept of mechanism of direction indicator
  • Mechanical system and prototype
