Precision drawing on your average touchscreen seems like wishful thinking.
However I've had this idea for a software stylus that acts like an extension of your finger and allows drawing with greater precision. See my rough diagram below. Essentially it's a pointer that follows your finger around the screen. Its angle can be adjusted so that from your vantage point it looks like the tip of your finger is coming to a point.

You simply move the pointer around and the line is drawn from the point of the stylus instead of somewhere under your finger, where you can't see it.
Obviously I haven't worked out all the details - such as how the pointer tells the difference between positioning the stylus and drawing with the stylus. I'm sure these kind of things can be sorted with further development. It could even have different shaped pointers for different shaped lines.
I'm calling it 'softnib'. A solution that allows for precision drawing without the need for an actual stylus.
What do you think - is it a good idea? Have you seen it before?
If it is a good idea let's hope someone sees this post who can actually implement it.
