In my last post regarding the installation of Project54 on a marine patrol boat, I mentioned that the boat environment presents a new set of challenges. One of these challenges is that it is very difficult to perform manual interaction while the boat is moving due to the rough motion resulting from hitting waves. When officers have to travel faster, for example when they respond to an emergency call, the motion of the boat is very jerky. The difficulty in performing manual interaction in this particular scenario is illustrated in the video clip below. In it, we are traveling at roughly 30 mph and I am attempting to interact with the Project54 software.

In this situation speech will likely be the best mode of interaction, however, as you can tell from the video there is a significant amount of engine noise that can be heard in the cabin. The engine noise can decrease the accuracy of the speech recognizer, and currently I am looking for an appropriate noise canceling microphone as a solution to this problem.
