Abstract
Using spoken language is the easiest and most natural way of communication for human beings. The communication between humans and machines using sounds or language is a huge move forward. This article demonstrates the development of a mobile application for managing household accounts with the integration of a speaking voice and touch-screen function on smartphones; this could also be used as a tool to manage household accounts for elderly Thai people. The content was evaluated by five experts to identify each feature of the developed mobile application. Afterwards, the developed mobile application was distributed to thirty-three elderly people. The findings showed that the elderly people were able to learn and use the mobile application effectively. The learning post-test results scored higher than the pre-test results. The effectiveness evaluation results in terms of the accessibility barriers that can be faced by elderly people while using mobile applications showed that the average mean was 4.13 and the standard deviation was 0.36 and the acceptance of the mobile application based on accessibility barriers that could be detected by elderly people while being used has high consensus. This indicates that the developed mobile application is effective for elderly users at a high level.
Highlights
The pre-test and post-test results after the mobile application training from thirtythree people revealed that the post-test results of the sample group after training was better than their pre-test results
The content consistency was evaluated by five experts in the field of information technology and accounting in order to select the features for the developed mobile application
The developed mobile application was distributed to the thirty-three elderly people; the results of the training as well as the pre- and post-learning tests showed that the samples scored higher on the post-test than on the pre-test
Summary
Thailand has entered an aging society in which the elderly population (aged 60 years old or more) increased from 6.8% of the total population in 1994 to 14.9% in 2014; 45.1% were made up of elderly men and 54.9% were taken up by elderly women. An aging society refers to the rise of the elderly population (when citizens aged 60 years old or over comprise 10% or more of the total population), while the youth and working populations reduce [1]. The fact that the elderly population accounts for more than 10% of the total population indicates a genuine aging society [2]. Scholars estimate that Thailand will have 14.4 million elderly people by 2025 and reach 27% of the total population in 2050, in which women will have a longer life expectancy by 45 years than men on average [1]
