Blind people are confronting a number of challenges in performing activities of daily life such as reading labels on a product, identification of currency notes, exploring unknown spaces, identifying the appearance of an object of interest, interacting with digital artifacts, operating a smartphone’s user interface and selecting non-visual items on a screen. The emergence of smartphone-based assistive technologies promotes independence, ease of use and usability resulting in improved quality of life yet poses several challenging opportunities. We have reviewed research avenues in smartphone-based assistive technologies for blind people, highlighted the need for technological advancements, accessibility-inclusive interface paradigm, and collaboration between medical specialists, computer professionals, usability experts and domain users to realize the potential of ICT-based interventions for blind people. This paper analyzes a comprehensive review of the issues and challenges for visually impaired and blind people with the aim to highlight the benefits and limitations of the existing techniques and technologies. Future research ventures are also highlighted as a contribution to the field.

盲人在进行日常生活活动时面临许多挑战，例如阅读产品上的标签，识别纸币，探索未知空间，识别感兴趣的物体的外观，与数字文物进行交互，操作智能手机的用户界面。并在屏幕上选择非可视项。基于智能手机的辅助技术的出现促进了独立性，易用性和可用性，从而改善了生活质量，但带来了一些具有挑战性的机遇。我们审查了针对盲人的基于智能手机的辅助技术的研究途径，强调了对技术进步，包含可访问性的界面范式以及医学专家，计算机专业人员之间的协作，可用性专家和领域用户，以实现针对盲人的基于ICT的干预措施的潜力。本文分析了视障人士和盲人面临的问题和挑战的综合综述，旨在强调现有技术的优点和局限性。未来的研究事业也被强调为该领域的贡献。
