Towards a virtual agent using similarity-based laughter production
نویسندگان
چکیده
Facial expressions of emotions are often described statically at their apex. Lately several researchers (Keltner, 1995) have shown through analysis of video corpora that emotions are expressed through a sequence of micro-behaviours. These micro-behaviours correspond to signals spread over the whole body (face, head, gaze, gesture, etc). All these signals do not have to occur simultaneously. Some of them occur more often at the beginning of expressions, some others at the end, some occur in a sequence, while others are synchronized (Keltner, 1995).

Enabling a virtual agent to join in laughing with a conversational partner using a similarity-driven audiovisual laughter animation
The AVLaughterCycle project aims at developing an audiovisual laughing machine, able to detect and respond to user’s laughs. Laughter is an important cue to reinforce the engagement in humancomputer interactions. As a first step toward this goal, we have implemented a system capable of recording the laugh of a user and responding to it with a similar laugh. The output laugh is automatically sel...
متن کاملTowards Multimodal Expression of Laughter
Laughter is a strong social signal in human-human and human-machine communication. However, very few attempts to model it exist. In this paper we discuss several challenges regarding the generation of laughs. We focus, more particularly, on two aspects a) modeling laughter with different intensities and b) modeling respiration behavior during laughter. Both of these models combine a data-driven...
متن کاملLOL - Laugh Out Loud
Laughter is an important social signal which may have various communicative functions (Chapman 1983). Humans laugh at humorous stimuli or to mark their pleasure when receiving praised statements (Provine 2001); they also laugh to mask embarrassment (Huber and Ruch 2007) or to be cynical. Laughter can also act as social indicator of in-group belonging (Adelswärd 1989); it can work as speech regu...
متن کاملInvited Talk: Modeling Socio-Emotional Humanoid Agent
In this talk, I will present our current work toward endowing virtual agents with socio-emotional capabilities. I will start describing an interactive system of an agent dialoging with human users in an emotionally colored manner. Through its behaviors, the agent can sustain a conversation as well as show various attitudes and levels of engagement. I will present our latest work on laughter. I ...
متن کاملLaughter animation synthesis
Laughter is an important communicative signal in humanhuman communication. However, very few attempts have been made to model laughter animation synthesis for virtual characters. This paper reports our work to model hilarious laughter. We have developed a generator for face and body motions that takes as input the sequence of pseudophonemes of laughter and each pseudo-phoneme’s duration time. L...
