Observation of appearance and physiological parameters in elderly to assess the aptness

The project was taken up under India and Slovenia scientific and technical cooperation. The objective of the project was to unobtrusively monitor daily living activities of elderly and subsequently determine their wellness. It would be achieved by measuring the effects of human vital signs when a person approaches non-invasive sensors, including video camera and with the application pattern analysis algorithms.

Unobtrusiveness depends on the ability to measure the effects of human vital signs when a person, during his or her daily activity, unconsciously establishes a direct or indirect contact with sensors built in the devices and elements of the living environment (beds, chairs, household appliances, foot-ware, mobile phones, etc.). A variety of high-tech sensors are available today (such as the accelerometers, fibre-optic interferometers, capacitive electrodes, optic and thermal cameras, radar, sonar, etc.) and some of such sensors along with the video camera are used to analyse the activities of the aged persons. Simulation reults are in Fig. 1.
