An assistive mobile application i-AIM app with accessible UI implementation for visually-impaired and aging users

A study conducted by the Department of Statistics revealed that 29,000 elderly people have registered for Visually Impaired Card in 2014, which was 51.2% of all visually impaired people. With annual growth rate of 1.56%, this number increased yearly by 1,100 people. According to the World Health Organization, 285 million people worldwide were estimated to be visually impaired, which is 4.24% of overall population in 2012. From an age distribution point of view, most visually impaired people, accounted for 2.76% of overall population, were above the age of 50. On average, there are 7 visually impaired people for every 100 people above 50 years old. In Taiwan, 549,000 people over age 50 are estimated to be visually impaired. The following statistics, calculated from the Ministry of Health and Welfare, shows the ratio of visually-disabled people to the total population of disabled users in Taiwan. Trend 1 uses a denominator equal to the total population of people with disabilities from the year prior whereas Trend 2 uses a denominator equal to the total population of disabled people in 2011 (Paasche and Laspeyres indices). We begin our data with year 2012 because the Ministry redefined classifications for certain disabilities, adding a new category called "unclassifiable" that may include people with visual disabilities. Traditionally, the Ministry follows the ICF (International Classification of Functioning, Disability, and Health) guidelines, but it will occasionally modify its categorization to fit the needs of its people. These two trends provide an estimate of the true ratio of visually-impaired persons to the entire disabled community which falls within these ranges. We conclude that there is a growing number of visually-impaired individuals, indicating a real need for society to address the problems that this population endures. leisure activities via a questionnaire survey. Furthermore, descriptive video service is used to as an accessible long-term care application for visually impaired senior users to solve disability circumstances and improve home care quality through visually impaired APP Proof-of-Concept (POC). The result of this research will serve as an important basis for other researches in related study-fields and as a reference for practical application. Moreover, this research serves to encourage profit-seeking enterprises to design user oriented products and to be benchmark for mobile accessibility services for people with disabilities and senior users.
