Natural social human–robot interactions (HRIs) require that robots have the ability to perceive and identify complex human social behaviors and, in turn, be able to also display their own behaviors using similar communication modes. Recently, it has been found that body language plays an important role in conveying information about changes in human(More)
As the world's elderly population continues to grow, so does the number of individuals diagnosed with cognitive impairments. It is estimated that 115 million people will have age-related memory loss by 2050 [1]. The number of older adults who have difficulties performing self-care and independent-living activities increases significantly with the prevalence(More)
A novel breed of robots known as socially assistive robots is emerging. These robots are capable of providing assistance to individuals through social and cognitive interaction. However, there are a number of research issues that need to be addressed in order to design such robots. In this paper, we address one main challenge in the development of(More)
In Human-Robot Interactions (HRI), robots should be socially intelligent. They should be able to respond appropriately to human affective and social cues in order to effectively engage in bi-directional communications. Social intelligence would allow a robot to relate to, understand, and interact and share information with people in real-world humancentered(More)
Recent studies have shown that cognitive and social interventions are crucial to the overall health of older adults including their psychological, cognitive, and physical well-being. However, due to the rapidly growing elderly population of the world, the resources and people to provide these interventions is lacking. Our work focuses on the use of social(More)
In this article, the workspace of planar wire-actuated parallel manipulators is studied. The investigation is based on two methods: an analytical method which formulates the workspace envelope by means of Cramer’s rule pertaining to the Jacobian matrix and the null space method from static analysis of manipulator. The workspace envelope method is extended(More)
Our research focuses on the development of a socially assistive robot to provide cognitive and social stimulation during meal-time scenarios in order to promote proper nutrition amongst the elderly. In this paper, we present the design of a novel automated affect recognition and classification system that will allow the robot to interpret natural displays(More)
