Many visually impaired individuals are found to be too passive or too aggressive in their social interactions. Lack of assertive behavior is related to the concept of learned helplessness. Components of assertive behavior are described with suggestions for enabling the visually impaired person to develop these skills. The underlying concepts of assertion training are explained along with specific techniques to be utilized in the school or rehabilitative setting. With a structured intervention resulting in improved assertiveness skills, blind or partially sighted individuals can increase their effectiveness in communicating with others and can feel more in control of their lives.

In general, a good interaction including communication can be achieved when verbal and non-verbal information such as body movements, gestures, facial expressions, can be processed in two directions between the speaker and listener. Especially the facial expression is one of the indicators of the inner state of the speaker and/or the listener during the communication. Therefore, recognizing the facial expressions is necessary and becomes the important ability in communication. Such ability will be a challenge for the visually impaired persons. This fact motivated us to develop a facial recognition system. Our system is based on deep learning algorithm. We implemented the proposed system on a wearable device which enables the visually impaired persons to recognize facial expressions during the communication. We have conducted several experiments involving the visually impaired persons to validate our proposed system and the promising results were achieved.

<p>Reproduction of copyright protected material in formats that are accessible to the blind and visually impaired persons constitutes a copyright infringement unless there are specific limitations and exceptions in place. Most countries do not have copyright limitations and exceptions for the benefit of the visually impaired in their copyright laws. This has contributed to the issue of book famine, meaning the unsatisfactory access to copyright protected material for the blind and visually impaired.  This thesis examines the claims of the visually impaired for improved access to copyright protected works in the context of the interface of human rights and intellectual property rights. This research demonstrates that insufficient access to copyright protected material is discriminatory against the visually impaired and negatively affects their human rights such as the right to education, information, health, employment, culture, and science. Moreover, the thesis analyses the international and domestic copyright law’s impact on the needs of the visually impaired. In analysing the international copyright law, the thesis evaluates the Marrakesh Treaty to Facilitate Access to Published Works by Visually Impaired Persons and Persons with Print Disabilities.  Highlighting the insufficient consideration for the rights of the visually impaired in domestic and international copyright laws including the Marrakesh Treaty, the thesis proposes adoption of a human rights framework for copyright law to the extent that it affects the human rights of the visually impaired. Such framework requires copyright law to accommodate those human rights of the visually impaired that are dependent on access to copyright protected material.  The thesis offers two categories of measures for creation of a human rights framework for copyright to the extent that it affects the human rights of the visually impaired. The measures include optimisation of already available options and adoption of new mechanisms. The first category discusses minimum mandatory copyright limitations and exceptions and the possibility to harmonise them. The second category covers extra measures such as clarifying the implications of different human rights and copyrights in the context of the book famine; ensuring compatibility of human rights and copyright when adopting policy and law; and, regular monitoring of the impact of copyright law on human rights.</p>

OBJECTIVE: To evaluate the effectiveness of mobile ophthalmic unit screenings and to investigate barriers between community care and resolution of the problem at a tertiary center. METHODS: This prospective study evaluated a convenience sample from 10 municipalities in São Paulo State, Brazil. Patients were assessed in the municipality by a mobile ophthalmic unit and underwent a complete ophthalmic consultation. Patients were referred as warranted to a tertiary hospital. RESULTS: The mobile ophthalmic unit screened 1,928 individuals and 714 (37%) were referred. The mean age of the referred patients was 57.12 (SD = 19.5) years with best corrected visual acuity of 0.37 (SD = 0.36) logMAR. Forty-seven (6.6%) patients were blind and 185 (26.5%) were visually impaired. Cataracts (44.7%) and pterygium (14.7%) accounted for most referrals. Of those referred, 67.1% presented to the tertiary center. The diagnosis by the mobile ophthalmic unit corresponded to the one by the tertiary center in 88.5% of the cases. There were a significantly higher number of blind and visually impaired persons among those who presented to the hospital. There was a significantly greater attendance among patients living in more distant municipalities from the reference center with a higher number of inhabitants and a greater number of ophthalmologists in the cities of origin (p < 0.05, all comparisons). Complete treatment was performed in 65.6% of patients, and loss to follow-up was the main cause of incomplete treatment in 50.7% of patients. A total of 313 cataract surgeries were performed, which reduced the number of blind patients from 20 to 2 and of visually impaired individuals from 87 to 2 (p < 0.001). CONCLUSIONS: Only 37% of the patients assessed by a mobile ophthalmic unit required referral to a tertiary hospital. Among the referred patients, 67.1% presented to the hospital, and complete resolution after treatment was approximately 65.5%. There was a significant improvement in visual acuity and a reduction in the prevalence of blindness and visual impairment postoperatively.

Quality education and rehabilitation programs for blind and visually impaired individuals may be threatened by the philosophy of service to disabled people currently prevailing at the federal level. This philosophy would treat blind and visually impaired persons as though their needs were the same as those of other handicapped persons. In fact, sometimes the needs coincide; sometimes they do not. Proper service delivery can be ensured only by understanding this philosophy, becoming aware of its subtle and overt impact on programs for people with visual impairments, and acting in concert with others who have similar concerns.

Although fax communications pose a problem of accessibility for blind and visually impaired office workers, with centralized readers’ services they could be used to address the wider reading needs of blind and visually impaired people. With this technology, blind persons with fax machines could send unknown print to readers at a centralized readers’ service, who would read facsimiles of the documents over voice phones. This article discusses the specifications for appropriate equipment and protocols and presents the preliminary results of a study of such a system.
