ICT for ageing well.



A- A A+


Light is used to meet visual needs of human beings (e.g. highlighting risks of falling), is applied for temporal orientation throughout the day (e.g. emphasising day-night rhythm), for spatial navigation during activities of daily living (e.g. illumination of a defined location areas) and is used as reminder as well as information signal (e.g. light spots and light signals). Light therefore has great potential for attenuation of age-related mobility impairments caused by reduced spatio-temporal orientation, worry about getting lost, and fear of falling.

To make use of light in this sense, we will implement a light wayguidance system in private homes of older people that performs a time- and motion-controlled change of intensity and color temperature of room lightings. We will use existing lightings in these rooms and supplement them with additional lighting equipment and electrical installation technologies. After modification, light characteristics of lamps will change automatically according to the personal daily routine of residents.

This, however, will not be a rigid system. At the same time, mobility parameters of the residents will be monitored (such as movements in and outside the home) and the results of analysing this data will be used to change the programming of light variations. The adjustment of light programming will be done automatically, nevertheless, residents can manually readjust their lights at any time.

The degree of mobility is an important indicator of health. For this reason we will integrate relevant parameters into a distributed information system as the basis for decisions about preventive provisions. This will give residents, at any time, insight into their health status, which can be shared with persons of trust (e.g. relatives, doctor).



Within this project we will develop and implement an intelligent light wayguidance system, which should attenuate age-related mobility impairments caused by reduced spatio-temporal orientation, worry about getting lost, and fear of falling. This guiding light will consist of up to date lighting technologies, innovative intelligent control algorithms, smart mobility monitoring systems, and a distributed information system for mobility parameters. Together with end-users and all stakeholders we will examine how these components can be combined with inter-personal care services.

Expected results and impact:

The outcome of the project is an intelligent light wayguidance system consisting of a variable set of flexible modules that work together with other heterogeneous home automation, information and communication systems as seamlessly as possible. The application of this guiding light system will support the spatial-temporal orientation of older people and thus sustain their mobility as long as possible.
