This manifested itself in the work of three undergraduates - Dan Parnham, who experimented with the interpretation of the pose of a mannequin by the use of a single webcam focussed exclusively on the input side of the augmentation problem during his Masters degree, Sean O'Mahoney, who developed the first incarnation what would come to be termed PenPets as his Masters project, and Enrico Costanza, who developed a variety of tangible augmented interfaces using fiducials stuck to blocks of wood, with augmentation provided variously by audio feedback ("Audio d-Touch"), and a projector ("Magic Desk"). Much of Audio d-Touch was created by Enrico in his spare time as a personal project, (with collaboration from the aforementioned Robinson, and Simon Shelley, another York alumni) while the Magic Desk became his Masters project.
