I want to develop a web app (using HTML5 components like <canvas>
and JavaScript libraries) that accepts user input from a stylus or a mouse but ignores touch input so you can safely rest your hand on the drawing canvas without it being interpreted as input unintentionally.
There is a similar question here but specifically I'm curious about a clever concept to avoid unintentional input with existing HTML5/JavaScript APIs.
Is this possible and if, how?
