Hi Daniel,
thank you for your kind words :)
It seems like the current left & right click implementations are not good/fast enough for you to replace the regular mouse. I assume you want two extra buttons on your IR pen for left & right click, and I agree that it would be more convenient.
In my opinion, the basic problem with your idea is that it requires a more complicated setup, raising the (technical) level for the inexperienced user. I assume that even the lack of off-the-shelf IR pens is preventing some people from getting started with the Wiimote Whiteboard. Commercial distribution of IR pens would solve the problem if the community could agree on a reference design. There has been some discussion about using Pulse-width modulation for detecting right clicks and even pen IDs, also proposed by Johnny Lee. However, I’m not aware of anyone who has done this yet. The problem is also that it requires more complicated IR pens, no way for the average user to build (which leads us back to selling IR pens).
The problem I see with your idea in particular is that it requires extra wires or wireless transmission to the off-screen LEDs. Wires are just not practical, and why not directly transmitting to the computer if already using wireless?
My proposal: Buy a cheap wireless mouse and use it exclusively for clicking. Or dissect the mouse and put the electronics into an IR pen. Add two buttons to your IR pen and use them to trigger the left and right mouse buttons on the mouse’s electronics. This is obviously not trivial to do but has the advantage that it doesn’t require extra software on the computer.
