Microsoft Surface
Today the Microsoft Surface arrived, finally. They arrived in big boxes suggesting big tables, but alas they are actually pretty small. Microsoft envisages them as lounge table, as such they are very low, too low to sit comfortably on a normal chair. Being used to the Circle12 DiamondTouch, the Surface is both small and heavy. Weighing about 80kg it is difficult to move it and the actual display area is about half the size of the DiamondTouch.
We were supposed to have two normal and one developer edition but it wasn’t very clear which one was which so we picked one and carried it to our office. This turned out to quite tricky, this thing is heavy and doesn’t have any clear handles. In the end we carried it by holding the projection-surface …
Once setup we had to fiddle a bit to get the powercable connected and find the proper (two) powerswitches. Once it booted it prompted us an EULA we had to accept. However the Surface is designed to be a standalone machine completely controlled by touch but before the touch was working we had to accept the EULA, which was only accessible by touch … hm
You need to accept to start touch, and you need touch to accept
So we had to plug in a mouse, but apparently we hadn’t chosen the developer edition since no usb ports where visible. The manual explained that we need to open up the side of the table to access the ports. After two screws and a bit of force we managed to open up the side and it gave us full access to all normal PC ports.
The surface insides
It asked us to create an admin account and once it was setup it gave us the choice to login as that admin or as TableUser, since we had no clue what the password for TableUser was, we logged in as admin. After a bit we were shown a fresh Vista desktop with a few shortcuts. The most obvious for us was the calibration tool. We calibrated our table and started a touch application. It failed to run complaining that the filtergraph was not found at the location specified. We neither had knew what a filtergraph was, nor what the location specified was. This got us stuck for quite a while, the manuals didn’t help and the online site with information was only accessible by invitation and due to some miscommunication(?) we were not (yet) invited.
Digging into things like registries, hidden folders and binary blobs we finally discovered that there are two versions of the calibration tool. One which does a background-light calibration and one which does a per camera calibration. We had run both, but we failed to notice that the latter had to run 5 times (5 cameras in the surface). Once we had done so the different surface programs ran without errors and without effect.
Pretty annoyed we banged our fist on the table and that seemed to have effect. It turned out that putting a lot of force on the table gave results, indicating a calibration issue. Having no idea how to finetune the calibration we started to experiment with different ways of touching. The current consensus is that it is designed for ubergeeks who never see the sun and are pure white; touching the Surface with a finger doesn’t give a result, wrapping the finger in white tissue suddenly does …
The 'attract' application
Hopefully we will figure out soon how to tweak the calibration and otherwise we need to buy a set of white surgical gloves to hand out to users
