Bilgisayar
kullanımının yaygınlaştığı günümüzde, insan-bilgisayar etkileşimi ile ilgili
yenilikçi çalışmalar hız kazanmıştır. Bu yeniliklerden bir tanesi de bilgisayar
kullanıcısı bireylerin duygusal durumlarının, makine ile öğrenilmesidir. Ofis
ortamlarında bilgisayarla çalışan bireylerin duygu durumlarının tespit
edilebilmesi, özellikle bu kişilerin moral durumu ile iş performansı ilişkisi
hakkında anlamlı bilgiler sunabilir. Bu fikirden hareketle, bilgisayar
kullanıcısının yüz ifadelerine dayalı anlık duygu tespiti gerçekleştiren
prototip bir sistem geliştirilmiştir. Geliştirilen bu sistem sırasıyla; yüz
tespiti, yüz işaretçilerinin tespiti, yüz işaretçilerine dayalı özniteliklerden
oluşan eğitim veri setinin oluşturulması ve kural-tabanlı sınıflandırıcı ile
anlık duygusal durum tespitini gerçekleştirmektedir. Çalışmanın özgünlüğünü
ifade eden özniteliklerin ayırt edici karakteristiğini anlamak amacıyla mevcut
eğitim veri seti destek vektör makineleri ile durağan bir şekilde
sınıflandırılmıştır. Sonuç olarak, sistemin başarımı 10-katlı çapraz doğrulama
ile %96,1 olarak tespit edilmiştir.
