Um and the last one is the working design. How exactly does it work in the technical sense. Um the other design stages , uh we will discuss that later. So we'll kop it  keep it with the functional design.  Okay , um before we think about remote control we will um work with some of the tools we have uh here. Um as you see now I can give a presentation.  Um it's also possible to use this one as well. You can uh uh display pr uh two presentations if you want to. Um  to um presentate , to show us uh a file you'll need to uh place it in your project documents folder , which is on your desktop , at least it should be. Um then we have this electronic white-board system.  Um yeah , I will show that now. Um you can draw on the board using this pen. There are little um uh
Sensors.
sensors , so do not grab it here , but a lit more a little bit more to the uh to the end. Um well , it  it's on the um eraser now , so we click the pen button. Okay , so not too fast writing. Um  you can insert a new um slide or or white-board uh uh file um by either using the insert function or by clicking the next button or the blank button. It's quite the same. Um all our um whi um uh SMARTboard um notes should be kept in the same file. So do not m make a new file. Just use this one uh during the day.  Um you can use the eraser to make something go away.
But we all use the same white-board file
