Blu-ray 3D engages viewers more than Blu-ray, which in turn is more engaging than standard DVD, a neurological research found.

The research was released this week by the Mindlab International team at the Sussex Innovation Centre on bahalf of the Blu-ray Disc Association.

Testing the attention, emotion and engagement levels of different home entertainment disc formats on a group of subjects, the study monitored subjects? heart rates, skin conductance levels (EDA) and brain activity levels (EEG) whilst they watched film clips and trailers in Blu-ray 3D, Blu-ray and DVD formats.

The study found that people's attention levels were 29% higher, their engagement levels were 18% higher and their emotional levels were 8% higher when comparing their reactions between Blu-ray 3D and standard DVD footage.
