I am at a phase of a project where I need to establish a proper testing method where I can measure how well the touch performance on different smart devices (tablets and smartphones). My primary test is performed in hand and conclusion given from my own experience, which I would like to back-up with a more measurable test.
To get some more practical stuff on the table I am basically working with SVG and touchevents, where the user can initiate a drag behaviour on SVG elements. The fact is that the dragging does not perform equally on all smart devices, which leads to this test.
I am interested in methods for performing these tests, Acid3 covers the compliance which I have in place.
