Order to the IT Service (real history)
XXX: Due to the fact that the working surface of the desk is covered with lacquer, the operation of the optical mouse is not quite correct, the mouse movement is sharp, often scratched, does not correspond to the movement assigned by the hand of the operator. In this regard, please allocate me a mouse carpet to improve my performance, preferably with a silicone pillow to support the wrist.
YYY: To prevent false operation of the optical mouse sensor, we suggest you use a specially designed sheet of A4 white paper. You can get it in room 506. Unfortunately, at the moment there are only sheets without a silicone pillow available, so the wrist operator will have to support itself.
If you want to use your own A4 sheet, keep in mind that with a paper density of less than 80 g/m2, the positioning accuracy of the handset will be insufficient for comfortable operation.
