The system could improve the way we interact with computers and perhaps allow disabled people to use computer-based communications devices, such as voice synthesizers, more effectively and more efficiently.<\/p>\n<p>Karthigayan Muthukaruppanof Manipal International University in Selangor, Malaysia, and co-workers have developed a system using a genetic algorithm that gets better and better with each iteration to match irregular ellipse fitting equations to the shape of the human mouth displaying different emotions. <strong>They have used photos of individuals from South-East Asia and Japan to train a computer to recognize the six commonly accepted human emotions &#8211; happiness, sadness, fear, angry, disgust, surprise &#8211; and a neutral expression<\/strong>. The upper and lower lip is each analyzed as two separate ellipses by the algorithm.<\/p>\n<p>&#8220;In recent years, there has been a growing interest in improving all aspects of interaction between humans and computers especially in the area of human emotion recognition by observing facial expression,&#8221; the team explains. Earlier researchers have developed an understanding that allows emotion to be recreated by manipulating a representation of the human face on a computer screen. <strong>Such research is currently informing the development of more realistic animated actors and even the behavior of robots<\/strong>. However, the inverse process in which a computer recognizes the emotion behind a real human face is still a difficult problem to tackle.<\/p>\n<p>It is well known that many deeper emotions are betrayed by more than movements of the mouth. <strong>A genuine smile for instance involves flexing of muscles around the eyes and eyebrow movements are almost universally essential to the subconscious interpretation of a person&#8217;s feelings<\/strong>. However, the lips remain a crucial part of the outward expression of emotion. The team&#8217;s algorithm can successfully classify the seven emotions and a neutral expression described.<\/p>\n<p>The researchers suggest that <strong>initial applications of such an emotion detector might be helping disabled patients lacking speech to interact more effectively with computer-based communication devices<\/strong>, for instance.<\/p><\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Inderscience Publishers press release via EurekAlert!: A computer is being taught to interpret human emotions based on lip pattern, according to research published in the International Journal of&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2012\/09\/researchers-develop-emotion-detector-using-a-genetic-algorithm\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[5,6],"tags":[188],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/6243"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=6243"}],"version-history":[{"count":7,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/6243\/revisions"}],"predecessor-version":[{"id":6323,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/6243\/revisions\/6323"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=6243"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=6243"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=6243"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
