<blockquote>
<p>Had this silly idea,
You open an app / web page.
You do a push up.
Your nose has to touch the screen for a moment and when it changes colour or beeps you lift the push up.</p>
<p>Ie to make sure you are not using momentum to go back up.</p>
<p>Can the camera calculate how close a nose / face is to the screen?</p>
<p>The simplest is just rely on touch.</p>
<p>Thoughts.</p>
</blockquote>
<p>So here&rsquo;s the touch version. A little pause at the bottom, with your nose in charge of the timer.</p>
