Direct field input with Pen device

I have a form that is used in the Notes Client on a Windows XP Tablet edition computer.

I already have a signature section that uses the pen and fields can be filled out by using the Operating System pen input method that has a pop-up box where the information is written, then inserted into the field.

However, the client would like to enter the data directly into the field, rather than have to use the pop-up. So a field would have to accept handwriting with a pen, then convert it into text.

I can’t come up with a way to do this.

Anyone else?
