Abstract

This disclosure presents an apparatus and its application for providing remote human assistance to the sight impaired. The sight impaired wears a mobile device composed of a portable camera, a transmitter for remote wireless communication, a microphone, earphones, and a tactile interaction device. A remotely located assistant observes on a monitor the images received from the sight impaired, and the accompanying voice messages or button actions from the device. The assistant interprets the images and guides the sight impaired through voice messages or through gestures The assistant's gestures are transmitted to the sight impaired through the tactile device.

Remote/Wireless Sight Interpretation for Visually Impaired People

      This disclosure presents an apparatus and its application for
providing remote human assistance to the sight impaired.  The sight
impaired wears a mobile device composed of a portable camera, a
transmitter for remote wireless communication, a microphone,
earphones, and a tactile interaction device.  A remotely located
assistant observes on a monitor the images received from the sight
impaired, and the accompanying voice messages or button actions from
the device.  The assistant interprets the images and guides the sight
impaired through voice messages or through gestures The assistant's
gestures are transmitted to the sight impaired through the tactile
device.

      The visually impaired often require assistance from a sighted
person when in unfamiliar situations that they are unable to
negotiate by means of hearing or other senses.  They also need to
communicate their query to the sighted person when there is a need
for clarification.  The most typical means to help the visually
impaired is to use help of sighted people or specially trained dogs
who accompany the visually impaired persons during trips.  This
method is either very expensive or not suitable for trips to new
places.

      The basic idea of this disclosure is to introduce remote
wireless connection to the centralized pool of visual interpreters.

      The basic way to support visually impaired people with a more
efficient service is to provide them with wireless connection to a
remote centralized pool of visual interpreters who can communicate in
real time with the clients.  Below we will describe the functional
aspects of this service.

Functional Description

The communication based on wireless connection should provide the
following functions:

(1) Visual or sound information from a client to an interpreter pool.

      To send on one end to person who provides help the detailed
information about events that occur on another end.

      A visual interpreter receives visual information about events
on another end which are sent via a portable visual setup on the
client person.  The requests of the client user can be transmitted by
voice or other medium of communication preferable to the client user,
for example, by voice or data link.

(2) Tactile or sound information from a pool to a client user.

      A pool must provide a client user with useful information in a
way that can be effectively perceived by the client.

      The basic ways of sending information to visually impaired
people are via voice and tactile sensors.

Voice to Visually Impared

      The pool can assist a visually impaired client by voice.  But
since the client must also hear surrounding information (street
noise, passing cars, etc.), this can divert attention.  This problem
can be resolved by secondary assistance via tactile sensors.  Helping
the visually impaired by hand sensors or glo...
