I am creating an application which allows the user to draw on their photo after they have taken one.
I want to know whether it is possible to make use of the accelerometer for the drawing part instead of our finger.
That means i selected a certain part of the picture where I want to draw on, then I use my whole phone as a “pen” to draw on the image instead of using my finger (using accelerometer).
May I know whether this is do-able? If so how?
Thanks a million!
Regards,
Grace
Only for very short quick lines. Any stroke or pen location would have to be the double integral of acceleration, which amplifies system noise and miscalibration so quickly that anything longer would be completely inaccurate, like right off the page.
