Oovit PT - From Wiimotes to Wockets

When Oovit PT was first conceived, we decided to use Wiimotes to capture user motion because of two reasons: (i) They provided us with low-cost motion sensing with the capability to provide data wirelessly over bluetooth (ii) It was a quick way for us to get started on the project because of existing support for connection to PCs.

Now that we have created a more tangible demonstration of our concept, we decided that it is time to move away from Wiimotes. One of the reasons to do this is that a bulky Wiimote is not conducive to a reasonably unobtrusive physical therapy experience. The second and more important reason to do this is that much smaller sensors would mean that users would willingly wear them for longer periods of time. This would enable continuous monitoring of motion not only during physical therapy but also during other activities throughout the day that might affect their condition.
 

Size comparison: Wiimotes and Wockets

While continuous activity detection would present us with its own challenges, we are thrilled by the implications of such continuous monitoring. Can aggregated data from several users provide us with enough insights to understand how a certain activity is affecting their rehabilitation progress? Can we provide real-time feedback through phones to guide the users when a certain activity is affecting them negatively? The possibilities are numerous and we are only getting started..
 
We would like to thank Selene Mota from the Changing Places (aka House_n) group for her guidance in introducing us to the Wockets... and our UROP Sonny Thai for enabling their use from our game in Unity 3D. Check out the Wockets website for more information on this cool research tool and stay tuned for more updates on Oovit PT.
