Summary
Hypothesis
The paper's hypothesis was that madgets can be used to improve interaction with interactive tabletops. This will allow improvement over the previous existing models since it can allow easier interaction with complex physical controls. Apart from that it would be easy to control, cheap, and would require no built in chips or power supply.
Method
This was implemented on 24 inch monitor(Samsung) while the actuation is modified through the usage of electromagnets(228 of them) and a Arduino board. A DSI (Diffused Surface Illumination) was used to allow touch recognition. The magnets were also kept cool during its usage by cycling the different magnets with each other during its usage. A method to control various complex controls (movement, configuration, orientation) was done through the usage of the actuation algorithm designed by authors. Visual tracking was used to allow sensing while transparent acrylic were also used for widget controls. The purpose of this combination was used to provide a sense of "easy to build" feeling for the users.
Results
Based on the usage of their prototype platform producing a new widget took less than an hour to produce. The tracking was done by using gluing the corresponding markers to the its control and this process took about two hours to do. Its performance shows the great possibility for allow cheaper and easier implementation as well as design.

Content
The paper was a explanation on the benefits and the superior points of this new method of surface interaction. The paper going into lengths on how the whole system works (fiber optics, magnets, actuation algorithm, etc). Over all the paper stated that the usage of this technology would allow low cost widgets and would make it easier to find better feedback
Discussion
I personally had little interest in the whole article. This was mostly due to the fact that the application of such a product in the real world. Although they mentioned widgets it was also apparent on what they can actually be used for. Although the idea was new and interesting (algorithm for example) i was not very convinced that this device would make a impact in the markets
