The document summarizes a presentation given by Alastair Gordon on using facial imaging technology without traditional surveys to measure emotional responses to marketing stimuli. It discusses how facial recognition software can automatically detect and encode facial muscle movements to decode emotions in real time. Examples are given of how measuring emotions second by second can provide insights into which parts of ads or stories evoke certain feelings and how responses may differ across demographics. Integrating these emotional profiles with survey data is said to add value to both approaches for evaluating creative works.
