Wireless system for elderly persons mobility and behaviour investigation

The paper contains a description of a measurement system intended for gathering data typically used for evaluation of elderly persons mobility and behaviour. The measurements are carried out with MEMS sensors assembled in the mobile device worn by the monitored person. Results of measurements are sent over wireless link to recording nodes for analysis. The paper describes system design and presents examples of recorded data. Proposals of system usage for mobility and behaviour investigation are also presented and discussed.
