The face is the window to the soul. We are exquisitely\u00a0attuned to reading facial expressions, emotions and other information from the face. We could even\u00a0think about the face as the ‘Graphical User Interface’ to the body.<\/p>\n

There is\u00a0a rich historic context for reading and exploring facial expressions.<\/p>\n

Without any effort, we maintain a massively multidimensional model that can recognize minor variations in shape and color. One theory says that color vision evolved in apes to help us empathize<\/a>.<\/p>\n

\"Chernoff<\/p>\n

Structurally, Herman Chernoff<\/a> came up with the idea that a facial expression could be reduced to 18 variables and that these could be used to visualize data sets. Chernoff Faces are discussed in every information visualization course, and are referenced in many papers. Yet the only serious use of faces in visualization is for calibration, not for data display. Faces are so special that we better know their perceptual properties really well before we can use them, which we don\u2019t.<\/p>\n

\"FACS\"<\/p>\n

Some more examples of artworks dealing with faces:<\/p>\n

Golan Levin created this software work, Reface, Portrait Sequencer<\/a> that\u00a0remixes\u00a0faces captured from recordings of visitors to the artwork.<\/p>\n

This generative facial project<\/a>\u00a0was made by artist Mattias Dorfelf uses software to make infinite illustrations of facial possibilities.<\/p>\n

And this project, Cheese by Christian Moeller brilliantly explores what is computationally detected as a smile and what is not.<\/a><\/p>\n

Assignment task description<\/strong><\/p>\n

Assignment Task 2 is to develop your\u00a0face from Part 1 into a face generator so that when\u00a0the mouse is clicked, the\u00a0facial expression changes – use\u00a0the random function in some way.<\/p>\n

Create a GIFF of your face being clicked (using licecap<\/a>) (or if you prefer, create a grid of 9 different facial expressions taking screenshots. To make the grid you will need to put this together in photoshop or equivalent) Post to the\u00a0blog this week.<\/p>\n
