About Sai Krishna
I am working in Machine Perception and Interaction (MPI) lab, Centre for Applied Autonomous Sensor Systems (AASS) at Örebro University from September 2016. I joined the Successful Ageing Programme and I am working on Human Social signals which include nonverbal behavioral Cues such as facial expressions, body postures gestures and proxemics to communicate with others and express their feelings. We are working to build a system in the context of Social Robot. This system is integrated with social cues particularly non verbal behavioral cue, Proxemics, to understand the social interaction and study the social behavior expressed by the person. These will be used by the robot to interact with people and work autonomously in the hour of need. This technology is mainly used in Successful Ageing programme for older people to stay in touch with family, friends and hospital faculty (like care takers or doctors)
I did my Masters in Computer Vision and Robotics then I worked as a researcher in Vision Labs at the University of the Algarve, Portugal.
