From the figures above, it can be seen that this layout and interface may be daunting for somone seeing this for the first time, let alone a 5 year old. To "design" a boat, one must change the numerical values of the parameters. The 3D simulation and 2D schematic will then update accordingly with the change(s). While someone with some experience in computer aided design may see this as intuitive and take the time to explore through changing the parameters.
This introduces introduces the problem we are facing when the paper boat design system is not suitable for 5 year olds. While the numerical input widget works for those of us in and out of LEMUR, we need to create an entire new GUI for this audience.
