Today’s invention is a set of pressure sensors which are installed in the feet or casters of an office chair.
These can be used to to pass information to a desktop computer and thus detect whether and for how long the occupant has been seated, their fidgeting or immobility, if they are perched on the edge of their seat and the straightness of their posture. It might even record such data over time and monitor weight and other longer-term changes.
The user’s machine can then issue health-related suggestions, via the screen, such as:
“time for a break?”,”maybe sit up straighter?”,”don’t lean back so far”,”you seem agitated, try herbal tea, not coffee?” etc.
