Information Technologies for Visually Impaired People

The two fundamental problems facing blind people are the difficulty of knowing where they are and getting about, together with the impossibility of having direct access to information, whether in written or in electronic form. The evolution of assistive technologies for the blind saw a boom at the end of the last century, opening doors to new exciting prospects for the present. According to the World Health Organization (WHO), blindness is a visual acuity of 20/400 or 0.05% in the better eye and with the best possible correction. The problem of helping the blind to integrate in everyday life has been addressed in some way or another since the beginning of time. But where once only the most basic form of aid or merely compassion was offered, now a more autonomous concept of life for the visually impaired is pursued.

The greatest problems facing the blind to acquire this autonomy and their solutions fall into two main categories:

  • The possibility of getting around independently: in other words, mobility and navigation aids.
  • Access to written information and social memory. This includes accessibility to digital information on computers by means of specialized digital interfaces.

The CEPIS News section here provides information about the 'Next Milestones and Events' following on from the completion of the Harmonise project in which CEPIS was involved. The UPgrade European NETwork this month includes a contribution from the the British Computer Society (BCS), CEPIS Member Society.
