Abstract

ABSTRACT About 200 million people with disabilities live with difficulties to carry out some daily activity. A significant portion of these people have visual impairment, in which such assistive technologies (AT) do not minimise the difficulties faced for safe access in everyday environments. To enable the AT to these people it is necessary to embark on artificial intelligence techniques, promoting the smart assistive technologies (SAT). The SAT have a processing that dynamically adapts to the person’s conditions and to the characteristics of the environment. The objective of this research was to develop an algorithm based on the informed search technique to optimise the routes for people with visual impairment. The algorithm was validated on 1600 combinations and optimised 52.8% of the simulations. This research presents relevant social potential, as it generates a SAT capable of assisting the decision-making of people with visual impairment.

视障人士路线优化的知情搜索算法:智能辅助技术的可能性

摘要：约有2亿残疾人在日常活动中生活困难。这些人中有很大一部分有视力障碍，这种辅助技术（AT）并不能最大限度地减少在日常环境中安全进入所面临的困难。为了让这些人能够使用AT，有必要研究人工智能技术，推广智能辅助技术（SAT）。SAT具有动态适应个人条件和环境特征的处理。这项研究的目的是开发一种基于知情搜索技术的算法，以优化视力障碍者的路线。该算法在1600个组合上进行了验证，并优化了52.8%的模拟。这项研究展现了相关的社会潜力，因为它产生了一种能够帮助视力障碍者决策的SAT。

期刊介绍： The aim of this interdisciplinary and international journal is to provide a forum for the exchange of original ideas, techniques, designs and experiences in the rapidly growing field of location based services on networked mobile devices. It is intended to interest those who design, implement and deliver location based services in a wide range of contexts. Published research will span the field from location based computing and next-generation interfaces through telecom location architectures to business models and the social implications of this technology. The diversity of content echoes the extended nature of the chain of players required to make location based services a reality.
