Imagine working in a giant office building. You are tasked with making some copies of certain documents, yet you still need a co-worker to sign off on one. With the Hololens on, you depart from your workstation. As you leave the boundaries of your personal working space, you give the voice command "Office Mode" you suddenly see the ring of a subtle, transparent mesh emanate around the room as the Hololens switches from workstation to office mode and connects to the Office network (You will probably have to give some sort of voice cue like Cortana or something so that the HoloLens knows you are speaking to it). You look around you and can see the names and job titles of your co-workers floating above their workspaces or on walls next to their office rooms. You can also see cues as to whether they are present, busy and or available ATM.
You look towards your co-workers desk to find that Bob isn't there. Not a problem, you speak the words, "Find Bob Laskey" and suddenly a path appears on the floor along with a floating (think transparent mini map) window displaying where Bob is. You follow the path to Bob, get his signature and then you are off to find a copying machine. Except this is the busiest part of the day and the machines on your floor are probably all packed. Not a problem, you simply say, "Find me a copying machine." Much like with finding Bob, you see a path along the floor pointing you in the direction of the nearest available machine.
After arriving at the copy machine you flick your fingers at it and suddenly a floating UI appears above it giving you all of the options you need in a standard display regardless what brand of machine you are using (Think HoloLens robot demo). You select the settings you want and say "Print" but nothing happens. You resort to trying to use the Physical panel and still nada. No problem, You speak the words "Call IT" A screen pops up with an IT guy on the other end and with your camera he is able to assess the situation and can determine whether or not it is an easy fix or if it would be better for him to make a trip there himself and for you to find another machine. In this case he thinks it is a simple one and you suddenly see holographic lines and circles appear on the copying machine as he directs you on his tablet. Between the two of you it takes only a minute and voilà, a working copying machine. You make your copies and head back to your desk.
Time for lunch! On your way back to your desk you speak the words, "Lunch menu." A floating menu from your workplaces cafeteria opens up and follows you. Each item has some quick glance health information associated with it. You speak the name of what you want and place an order. The menu window now disappears and is replaced with a much smaller timer with the approximate pick up time for your meal and to alert you when ready. After turning your assignment in at your desk you head to the cafeteria and are wondering if co-workers are there whom you are working on a project with. You speak the words "Display Project group" and suddenly you see the names of your project group in various directions all around you indicating where they are ATM. Several of them look to be at the cafeteria so you head that direction. You pick up your meal on the way to your co-workers while removing your hololens and placing it on one of the dozens of charging stations installed through out the cafeteria and office building
