post Emotional Algorithms.

February 13th, 2008

Spent day working on first prototype. The images need replacing – will shoot stills over the next few days, maybe tomorrow? Also, it is rather blunt – one image for disgust, anger etc. Basicall – shot in profile – seven images for each emotion. The male and female face each other. Each others emotional response triggers the aprropriate emotional response. Looks good, but lighting isn’t right. should be shown on two monitors. flat screen. Matt and I can pose tomorrow?. Also want to shoot pablo looking into the mirror for the first time. tomorrow?

Looking at the algorithmic codes that trigger the work. Need more work. Will send onto Chris Frith and Dylan evans. He sent through these questions last week, a lot of which I don’t know the answers for. Reading Dylan’s short book on emotions at the moment. Simple, but great. Chris’s book arrived today.

“Facial feature tracking is hard enough. My PhD student in Bristol was using Active Appearance
Models for tracking, but this re-quires manually labelling of training footage, which is tedious and introduces errors. Automatic landmarking algorithms enable a more accurate ?tting. Do you know what the MIT team is doing to track facial features?”

emotion[EMOTION_NEUTRAL][POSSIBLE_RESPONSE] = new Array(EMOTION_NEUTRAL, EMOTION_NEUTRAL, EMOTION_HAPPY, EMOTION_SAD);
emotion[EMOTION_NEUTRAL][POSSIBLE_FOLLOW_UP] = new Array(EMOTION_NEUTRAL, EMOTION_HAPPY, EMOTION_SURPRISED, EMOTION_DISGUSTED, EMOTION_ANGRY, EMOTION_SAD);

emotion[EMOTION_HAPPY][POSSIBLE_RESPONSE] = new Array(EMOTION_HAPPY, EMOTION_SURPRISED);
emotion[EMOTION_HAPPY][POSSIBLE_FOLLOW_UP] = new Array(EMOTION_NEUTRAL, EMOTION_HAPPY, EMOTION_SURPRISED);

emotion[EMOTION_SURPRISED][POSSIBLE_RESPONSE] = new Array(EMOTION_NEUTRAL, EMOTION_HAPPY, EMOTION_DISGUSTED, EMOTION_ANGRY, EMOTION_SAD);

post Neil’s talk – Emotional Contagion event

February 12th, 2008

Met with Neil Harrison to discuss talk, timings at the Dana Event. Neil will be talking about:

“Human society operates through cohesive social relationships. One characteristic of our social interactions is an ‘intuitive’ ability to understand other’s mental and emotional states. In parallel we have a tendency to mimic the body posture, gesticulations, emotional expressions and even physiological bodily responses of others. I shall discuss the mechanisms underlying this automatic mimicry, its role in empathy and intersubjectivity and how individual differences in mimetic systems may underlie disorders such as Autism and Tourette Syndrome”.

post how to assess the smaller micro expressions?

February 12th, 2008

Had a chat with physiologist Harry Witchell about the project. To analyse emotional expression he is using “image pro plus” image analysis software. The process for Harry is quite analogue – he applies black dots on face and then analyses. He mentioned an interesting group at Carnegie Melon looking at facial emotion recognition. Harry believes his knowledge of understanding facial expressions is more implicit – he says he can tell you exactly what muscles to move to achieve certain facial expressions – but he believes the people who have the most understanding of the subtleties of expression are the animators. A lot of the technology, though complex can still not make sense of the smaller micro expressions that make up different emotional reactions. Constantly need to keep in mind we are working with fluid, human faces, not static computer models. the fleeting nature of emotions.

post Nokia Only Planet conference – Espoo, Finland

February 11th, 2008

Great news – they sent Vilja from the Nokia Research Group in Tampere to chat with me – she started to tell me what there interests were and how I could be involved with them with some of my projects/reserch. Fantastic development for the mobile projects. I had put in application last year – Synapse/ARC. We ot the ozco funding but not the ARC funding. We needed more industry links. Working with Andrew Brown and Christian Jones. Christian contacted me a couple of weeks ago saying that he wants to resubmit.

Will fly back to Tampere in April to further meet with them. Sounds really interesting, but hard to talk about with NDA’s etc.
