Tablaction stands for tablet + interaction.
In the way that people draw or manipulate objects, it is more natural that they use tools when they draw and cut, otherwise they use their bare hands to move objects. However, touch and stylus inputs have little difference in interaction and they cannot be inputted simultaneously.
To overcome the hardware limitation, we made a touch-mimicking stylus which is algorithmically identified with its embodied pressure sensor. We suggested interactions for the next generation of tablet. Fingers zoom, type, and select objects and stylus draws. Cutting was suggested as an interaction combining touch and stylus.
