Abstract
Elderly people tend to forget their path within their living areas for example, within their own residence or within the area of an old home due to the aging process. Moreover, in a developing country, the cost of caregivers for elderly adults is an extra burden to the family. Thus giving quality-care to elderly people has become a great concern to every nation specially to the developing countries. The objective of this paper is to develop a wearable system to assist elderly people for path finding in indoor environment. In this paper, firstly a requirements elicitation study was carried out to understand the needs and problems of the aging population for their normal movement in an indoor environment like old home. Secondly, an wearable system was developed using arduino, infrared module, speaker and GSM. The system includes two key features: a) The system can identify the current location of the elderly people within the specified area, takes destination as input and it gives audio guidance about the path direction to the user; and b) The elderly people can call the specific person giving him or her the current location from where the help is requested. Finally, a light-weighted experiment was conducted with twelve participants(elderly people) in an indoor environment. The evaluation result showed that the system works effectively and efficiently; and the participants showed satisfactions of using such kind of system for their well-being.
