3D Virtual Environment System Applied to Aging Study – Biomechanical and Anthropometric Approach

摘要

The percentage of people over 60 years increased from 8.6% in 2000 to 10.8% at Brazilian population in 2010. In 78 cities of Brazil this portion of citizens already represents 20% of the total population. In this context, fall is one of the most serious problem of aging process, and it is being recognized as an important public health issue because it is considered a major source cause of disability to older adults. This is a matter of concerning to older people because can lead to physical handicap and loss of independence. The purpose of this paper is to present a 3D digital interactive environment to work with 3D digital human models applied to aging study. The 3D interactive platform framework involved: first step - scanning older adults and caregivers at a 3D Whole Body scanner and captured caregivers motions using 17 inertial sensors from XSENS Technology; second step- 3D modeling and simulation - scans and motion data are incorporated to virtual environment; third step - study reports and e-book. The conclusion are: the simulation will assure more democratic visualization and improve available information for the stakeholders involved, as designers, architects, health personnel's in the benefit of senior population, the 1D and 3D anthropometric measurements database of the caregivers and old adults will be a tool that can help designers and health cares in the future to improve design and care services for senior people in order to improve safety and quality of life. The 3D digital interactive environment is still under development. Also this system could be used to interact with the caregivers as a game to training in order to improve the daily care services tasks.
