The intention of this paper is to provide an overview on the subject of Human-Computer Interaction. The overview includes the basic definitions and terminology, a survey of existing technologies and recent advances in the field, common architectures used in the design of HCI systems which includes unimodal and multimodal configurations, and finally the(More)
Saliva is of paramount importance for the maintenance of oral and general homeostasis. Salivary hypofunction predispose patients to disorders such as dysgeusia, pain and burning mouth, caries and other oral infectious diseases, dysphagia and dysphonia. The aim of this study was to provide an update on the aetiology, diagnostic methods and therapeutic(More)
In order for cognitive robots to act adequately and safely in real world, they must be able to perceive and have abilities of reasoning up to a certain level. Toward this end, performance evaluation metrics are used as important measures to achieve these goals. This paper intends to be a further step towards identifying common metrics for task-oriented(More)
OBJECTIVE The present pilot study aimed to assess the effect of low-level laser therapy (LLLT) on hyposalivation and xerostomia as a consequence of head and neck radiotherapy. BACKGROUND DATA The benefits of LLLT in salivary flow have been shown; however, there are no studies investigating its effects on patients who have already undergone radiotherapy(More)
In this paper, we propose a face detection framework that combines both feature, and skin pixel approaches, while making the framework self adaptive which is important for non controlled environmental conditions. The framework uses skin color information to reduce the search space for faces by localizing the probable skin regions using a mixture of(More)
In this paper we aim at developing a system where in one can train robots to perform a task by performing the task once, manually. Such a system would reflect on the human methods of teaching wherein a person teaches a child how to perform a particular task by showing them how it is done by actually performing it once himself. As a child observes the(More)
