1) Neurotalent of the year 2013
Vote for Peter Lewinski as the Neurotalent of the year 2013! To assess ad effectiveness Peter Lewinski used facial coding software that tracks over 500 superimposed key-points on a 3D artificial facemask. He gathered online 900 recordings (0.7 million frames) of facial reactions to advertisements and analyzed over 4.1 million unique data points.

Relational Agents: the use and testing of avatars for HCI

Posted by Annelies Verkerk on Jul 16, 2013

Relational Agents (RAs) are computer constructs designed to interact with humans in a way that promotes the long-term formation of social and emotional bonds. Integrating social psychological principles of relationship building such as empathy, shared self-disclosure and emotional feedback into the RA interface helps to establish these bonds. Relational agents are generally created with an anthropomorphic (i.e. human-like) form that may be more or less realistic, varying from cartoon-like two-dimensional drawings to animated three-dimensional models developed with advanced graphics software. This type of model, or avatar, is known to most as a character representation found in third-person video games in which the game player character is visible. However, RAs are usually limited to frontal views from the shoulders or neck up due to constraints imposed by limits on computer processing power and the simulation capabilities of artificial intelligence algorithms. The video shown here was created as a final project for a Motion Capture class at New York University, and is intended to illustrate the potential uses of RAs as well as methods for testing the acceptance of such agents by their target audience.
