comparing multi-touch interaction techniques for manipulation of an abstract parameter space
The adjustment of multidimensional abstract parameter spaces, used in human-in-the-loop systems such as simulations and visualizations, plays an important role for multi-touch interaction. We investigate new natural forms of interaction to manipulate such parameter spaces. We develop separable multi-touch interaction techniques for abstract parameter space manipulation. We investigate using the index and thumb to perform the often-repeated sub-task of switching between parameters. A user study compares these multi-touch techniques with mouse-based interaction, for the task of color selection, measuring performance and efficiency. Our findings indicate that multi-touch interaction techniques are faster than mouse based interaction.
