The system works by mounting the display - a commercial, off-the-shelf 3D monitor with multi-touch capabilities - onto a robot arm connected to the same computer. As the user pushes their finger against the screen to interact with the display, the robot arm pushes back - and can alter the strength of that feedback as required. One example used during the demonstration was an array of virtual blocks constructed from different materials: stone, wood and sponge. Each was designed to behave as realistically as possible in terms of weight and friction, with the robot arm making the user work harder to push the stone block backwards than the wood or sponge blocks.Further details can be read at Bit Tech.
'I had been interested in the notion of putting a robot behind something you could touch,' claims Sinclair in a blog post on the matter. 'Originally, I had wanted a robot arm with many degrees of freedom but complexity, costs, and safety issues narrowed down the options to one dimension of movement. At that point, I was sure that others must have already looked into this scenario, but after looking at the literature, it turned out no one had done this.'
