So what if you teach seniors, or in fact you have to "make do' with a traditional whiteboard that is fixed and cannot be easily moved? Well, the secret to making it interactive is just the same - you have to enable the users to easily reach all corners of the projected image. We always recommend that the image size is less than 1.5m wide for a normal classroom, as that allows everyone to see, but keeps the picture sharp and accessible. Unfortunately, even at this size, many students simply cannot reach the top corners of the image. Well the solution is very simple - give them something to stand on! For want of a better word, we will call the item a 'step'. You need to keep the step just deep enough for board users to feel comfortable on, but no more, as if they stick out from the board too much, they will be in the way. The height of the step surface will depend on the height of the students but around 150mm (6 inches) is often about right. The actual construction is very simple. A piece of mdf board with 150mm spacers undeneath is both inexpensive and simple to build. If your property personal can't make them, a handy parent, woodwork teacher, or a friendly builder, can knock them up in no time.
If you wish, you can even buy commercially made examples (see below).
