With rapid increase in the size of videos online, analysis and prediction of affective impact that video content will have on viewers has attracted much attention in the community. To solve this challenge several different kinds of information about video clips are exploited. Traditional methods normally focused on single modality, either audio or visual. Later on some researchers tried to esta...

Non-facial and non-verbal methods of affective expression are essential for naturalistic social interaction in robots that are designed to be functional and lack expressive faces (appearance-constrained) such as those used in search and rescue, military, industry, and law enforcement applications. This research identifies five main methods of non-facial and non-verbal affective expression (body...

We present a dog-tail interface for utility robots, as a means of communicating high-level robotic state through affect. This interface leverages people’s general knowledge of dogs and their tails (e.g., wagging means happy) to communicate robotic state in an easy to understand way. In this paper, we present the details of our tail construction, and the results of a study which explored a base ...

Cognitive agent programming frameworks facilitate the development of intelligent virtual agents. By adding a computational model of emotion to such a framework, one can program agents capable of using and reasoning over emotions. Computational models of emotion are generally based on cognitive appraisal theory; however, these theories introduce a large set of appraisal processes, which are not ...

We report work on adding affect-detection to an existing e-drama programme, a text-based software system for (human) dramatic improvisation in simple virtual scenarios, for use primarily in learning contexts. The system allows a human director to monitor improvisations and make interventions, for instance in reaction to excessive, insufficient or inappropriate emotions in the characters’ speech...

Autism is a mental disability that requires early intervention by educating autistic children on the everyday social, communication and reasoning skills. Computer-aided learning has recently been considered as the most successful educational method and various CAL systems have been developed. In this paper we examine the existing CAL systems and platforms and discuss the benefits of adding an a...

Affective computing researchers adopt a variety of methods in analysing or synthesizing aspects of human behaviour. The choice of method depends on which behavioural cues are considered salient or straightforward to capture and comprehend, as well as the overall context of the interaction. Thus, each approach focuses on modelling certain information and results to dedicated representations. How...

In this paper, we demonstrate how approximation structures called sufficient semirings can provide information about measure-preserving dynamical systems. We describe the basic properties of measure-preserving dynamical systems and illustrate their connections to sufficient semirings by investigating the dyadic adding machine.

Mandarin is a typical tone language in which a syllable possesses several tone types. While these tone types have rather clear manifestations in the fundamental frequency contour (F0 contour) in isolated syllables, they vary considerably in affective speech due to the influences of the speaker’s mood. In the paper the Fujisaki model based on the measured F0 contour is modified to adapt for affe...
