The BBC is pressing ahead with plans to utilise new facial coding technology – revealing viewers’ subconscious “emotional attachment” to programmes – after running successful trials.
Developed by a British start-up, CrowdEmotion, the technology uses cameras to record individuals’ expressions and actions.
Facial movements are recorded on a second-by-second basis and the results are divided into six possible emotions: sadness, puzzlement, happiness, fear, rejection and surprise.
The cameras allow researchers to measure the often subconscious responses people have to visual content.
CrowdEmotion is working with the Insight division of BBC Worldwide, the corporation’s commercial wing, on projects which could be used to help the BBC gauge how viewers react to particular programmes.
A pilot experiment, measuring 5,000 people’s conscious and subconscious emotional responses to marketing campaigns on the BBC.com website – from clients including HSBC – has proved a success, BBC Worldwide said.
The BBC wanted to discover if audiences would respond more positively to content which was clearly labelled as originating from a commercial brand.

Facial coding showed a 77 per cent increase in “explicit positivity” towards the brand’s advertising and a 14 per cent increase in “subconscious positivity” when it was clearly marked as sponsored content.
The BBC’s advertising division said the technology “enabled us to find out the emotional response of each person and how they truly felt about the content they were viewing, rather than just relying on traditional analytics such as dwell time and page views”.
