SMART CHAIR FOR WORKING CONDITIONS OPTIMIZATION

Abstract

There is a growing tendency for people to spend more and more hours of their day sitting.
This position leads to an increase in the postural problems in the population. For workers
who have to spend long hours at work, in a seated position, investment should be directed
towards the development of equipment that improves their working conditions, such as
smart instrumented chairs with warnings of changes in position. With this work we propose
a standard office chair instrumentation approach, designed to allow monitoring
physiological parameters such as: posture of the seated person (user); body temperature; and
respiratory frequency. The system also allows monitoring environmental parameters such as:
temperature; relative humidity; atmospheric concentration of carbon dioxide (CO2); noise;
and light levels. The chair enables the interaction with control equipment to adjust the
comfort level, advising the need for rest time, repositioning notifications, and the real time
visualization of data, using applications for Windows and Android.
