The Structural Dynamics and Intelligent Infrastructure lab participated in the College of Engineering and Computer's E-week open house. Ramin, Benjamin, Phillip and Albert created a game that required participants to retrieve an object from a classroom without being detected. Floor vibrations were monitored as participants walked through the room. Participants were "detected" if the floor acceleration went above a specific threshold. This game was intended to show participants how floor vibrations can be used to monitor human activity, including fall detection.
