These are the simple wireframes created at the start of the project, to work out all the tools and buttons needed. The top two graphics illustrate how users should be able to stand on either side of the white board and easily reach the clickable items. I called this the 'teacher's arc' and the term stuck, and also created a 'Swap sides' button to suit both left and right-handed teachers.

Above is the final version of the interactive white board product.

Above is an example of a wireframe for the 'Digital Student Book' - this was a tablet product so positioning the navigation and interactive elements needed to be carefully considered.
