Thermal Infrared Imaging-Based Affective Computing and Its Application to Facilitate Human Robot Interaction: A Review

Abstract: Over recent years, robots are increasingly being employed in several aspects of modern society. Among others, social robots have the potential to benefit education, healthcare, and tourism. To achieve this purpose, robots should be able to engage humans, recognize users’ emotions, and to some extent properly react and "behave" in a natural interaction. Most robotics applications primarily use visual information for emotion recognition, which is often based on facial expressions. However, the display of emotion… Show more

“…These investigations have used physiological signals measured with contact sensors [ 10 , 11 , 12 , 13 , 14 , 15 ]. Additional studies have been carried out to detect emotions using infrared thermography [ 16 , 17 , 18 , 19 ]. These studies have generated great interest due to the fact that this technology is non-invasive, cost effective, and insensitive to lighting [ 20 ].…”

“…Thermal IR imaging is a well-known and widely used imaging technique that enables contactless assessment of the skin thermal distribution [17][18][19]. Capturing the infrared radiation spontaneously emitted by the body, the thermal camera is able to convert it into a digital map of the body superficial temperature profile [20,21]. The technique has become an important tool in medical research, thanks to its contactless, non-invasive, and security features [22,23].…”
