An Audio-Based 3D Spatial Guidance AR System for Blind Users. | LitMetric

AI Article Synopsis

  • Augmented reality (AR) can significantly assist blind users by offering audio information about their surroundings and guiding them through various applications.
  • The CamIO app enhances accessibility by providing real-time audio feedback when users touch different physical objects using a stylus.
  • A new 3D spatial guidance feature has been developed to help blind users locate points of interest, showing promise through experiments that confirm its effectiveness in providing verbal navigation assistance.

Article Abstract

Augmented reality (AR) has great potential for blind users because it enables a range of applications that provide audio information about specific locations or directions in the user's environment. For instance, the CamIO ("Camera Input-Output") AR app makes physical objects (such as documents, maps, devices and 3D models) accessible to blind and visually impaired persons by providing real-time audio feedback in response to the location on an object that the user is touching (using an inexpensive stylus). An important feature needed by blind users of AR apps such as CamIO is a 3D spatial guidance feature that provides real-time audio feedback to help the user find a desired location on an object. We have devised a simple audio interface to provide verbal guidance towards a target of interest in 3D. The experiment we report with blind participants using this guidance interface demonstrates the feasibility of the approach and its benefit for helping users find locations of interest.
