Perceptual threshold trigger

A method of tracking a user's consumption of digital content, comprising:

• communicating a block of content to a remote processing device for playback thereon, the block of content having a known content playback duration, the block of content also having associated therewith, a post block verification duration;
• collecting, during playback of the block of content on the remote processing device, a perception indicator;
• comparing the collected perception indicator against a perception threshold;
• performing a post block verification, the post block verification beginning immediately after playback of the block of content and lasting the post block verification duration;
• receiving feedback during the post block verification process;
• and
• determining a contingency result, the contingency result based upon the comparison of the perception indicator to the perception threshold, and the received feedback;
• wherein:
• determining a contingency result, the contingency result based upon the comparison of the perception indicator to the perception threshold, and the received feedback, comprises triggering an automated electronic transaction if a user of the remote processing device satisfied both a first contingency, corresponding to the comparison of the perception indicator to the perception threshold, and a second contingency, corresponding to detecting that valid feedback was received within the post block verification duration.
