The global population is moving toward an ageing population. Many countries are improving their technology to create smart cities suitable for the elderly. With the development of smart devices, people can make their life more convenient and can use phone APP to help the older with medical or health management. With the degeneration of their body, their sense of touch decreases, which in turn affects their feelings of haptic feedback for smart devices. Therefore, the study is aim to measure haptic feedback differences between elderly and young people, and to provide the manufacturers of mobile devices development as a basis for elderly have a good haptic feedback experience and improve the quality of use. The study was divided into two phases, a total of 58 participants recruited, of whom 27 people were 18 to 50 years old and 31 people over the age of 50, and through comparing haptic vibration feedback intensity by different vibration frequency and vibration time of mobile devices to explore whether there is any feeling difference between two ages.
