Inwerk MasterMove® seat sensor system
The personal health coach at work
10,000 moves - movement is the new office ergonomics
Those who move more prevent illnesses, show studies by sports scientists and orthopaedists. Health insurance companies subsidize digital systems for more exercise. In the office, the place where we spend 8 hours or more, there is so far little specific. To date, only the office swivel chair and electrically height-adjustable desk tools exist for the dynamic components of sitting or standing-sitting dynamics.
How are the chair and electric table used ergonomically?
The MasterMove® seat sensor replaces the previously static office ergonomics of an optimal sitting posture with the tracking of dynamic sitting and standing. MasterMove® serves the health prevention by counteracting lack of movement in the office job.
MasterMove® analyzes the individual movement behavior, recognizes the need for preventive action and communicates what the user should do long before the body reports pain. The movement initiated by the system helps to avoid physical discomfort, contributes to maintaining performance and well-being at work and can reduce the number of sick days lost due to illness.
MasterMove® constantly measures, compares and animates instead of traditional behavioural hints such as the "90-degree knee and elbow flexion theory" for chair adjustment. The reference point is the number of movements. Analogous to the step counter with the reference size of 10,000 steps, here there are 10,000 moves - individually related to the user and his behaviour. Almost incidentally, so-called dynamic sitting is integrated into the 8-hour day and can therefore be performed by anyone. Without having to wear anything such as a bracelet or subscribing to a sports studio.
MasterMove® integrates digital sensor technology into office swivel chairs that were previously purely mechanical. MasterMove® is a mini-computer in matchbox format with several sensors, storage media and signal transmitters as well as a well-known wireless connection module and app. Inconspicuously fixed to the underside of the seat, it works continuously when the chair is occupied. MasterMove® monitors the sitting behaviour in the same way as a personal coach, who is constantly attentive and does not miss a thing. Like a pedometer, the system records the number of all movements, but also measures their intensity several times per second in terms of acceleration, angle of rotation and angle of inclination and relates these values to each other. From this, MasterMove® calculates the personal movement profile and provides the user with individual recommendations for optimal sitting behaviour: for the sitting posture, for the correct adjustment of the office chair and for a healthy, regular change of position (stand-sit-dynamics). These are not general tips, but individual recommendations derived from the analysis of personal behaviour. The data is transferred to the smartphone via Bluetooth and stored as statistics (only for the user!). All this functions permanently and completely automatically, without the need for any manual intervention.
MasterMove® encourages healthy movement on the office chair and informs via a reminder function about haptic, acoustic or visual signals when it is time to get up (e.g. to work standing at the height-adjustable desk). The system also registers how long the user then works standing up or leaves his workplace for continuous coaching and personal sitting statistics.
In addition to the movement behaviour, MasterMove® constantly records the ergonomically relevant environmental conditions in the office: humidity, room temperature and volume. If defined limit values are exceeded or fallen short of, the system responds, for example, with a recommendation to ventilate or to speak more quietly.
