System Description:
A small gadget with a display. The system tracks a users activity at his own workplace through multiple sensors and if considered necessary, changes the working environment by increasing the desk height. All proceeded actions can be seen in the display. Further, an Avatar gives feedback concerning the air quality and suggests to open or close a window for a certain time.

System Description:
The system measures the air quality and muscle activity of the user to prevent the development of headaches. An air quality sensor is used to measure the quality of the air.
An EMG measures the activity of the muscles in the shoulders and/or neck area.
If the air quality becomes too poor (for example, falls below a certain level or deteriorates continuously over some time) or the user has not moved sufficiently over a longer period of time, they are alerted.
In this case, an LED strip starts to light up.
The user can then decide to open the window, change his sitting position, or do muscle relaxation exercises. Alternatively, he can simply ignore the strip and continue working without changing anything about the situation. If the user moves again, or if the air quality improves, the LED strip stops glowing. Alternatively, it could switch between green and red (or more colors) to indicate the different states.
The data on air quality and muscle movement is collected to detect changes. An overview display visualizes the data and shows the current state in the form of a human head that gets headaches. The space around the head reflects the air quality. The head is used to display too little movement. The exact visualization is still to be worked on.
