The aim of this project is to design a security device for elderly people which would trigger a warning system and alert nearby neighbours and security guards for timely help. The purpose of the research is to find out the easiest way to communicate with the elderly in case they need help. To understand the problems faced by the elderly regarding security, the author has conducted several user studies and reviewed many newspaper articles and other literature surveys. Design ideas were developed for individual problems faced and later collated and analysed to develop final concepts. The author puts forward a concept of Ubiquitous computing in the form of a wearable technology that provides him with invisible security everywhere within the house at all times. This was proposed after conducting qualitative and quantitative experiments on the elderly using the wearable device. The early results show that this design proves to be useful and usable for the elderly.
