Automatic Interpretation of Human Head Movements
نویسندگان
چکیده
This paper describes a complete face tracking system that interprets human head movements in real time. The system combines motion analysis with reliable and eecient object recognition strategies. It classiies head movements as \yes" (nodding head), \no" (shaking head) or \nothing" (still head). The system's skill allows contactless man-machine interaction, thus giving access to a number of new applications.

Automatic annotation of face velocity and acceleration in Anvil
We describe an automatic face tracker plugin for the ANVIL annotation tool. The face tracker produces data for velocity and for acceleration in two dimensions. We compare the annotations generated by the face tracking algorithm with independently made manual annotations for head movements. The annotations are a useful supplement to manual annotations and may help human annotators to quickly and...
متن کاملAutomatic Interpretation of Negotiators' Affect and Involvement Based on Their Non-verbal Behavior
Valid interpretation of the nonverbal behavior of the people involved in negotiations is important. Computational agents that are designed for negotiation benefit from the ability to interpret human nonverbal behavior for communicating more effectively and achieving their goals. In this paper, we demonstrate how the mode of involvement and relational affect of the negotiators involved in the in...
متن کاملA Low-Cost Head and Eye Tracking System for Realistic Eye Movements in Virtual Avatars
A virtual avatar or autonomous agent is a digital representation of a human being that can be controlled by either a human or an artificially intelligent computer system. Increasingly avatars are becoming realistic virtual human characters that exhibit human behavioral traits, body language and eye and head movements. As the interpretation of eye and head movements represents an important part ...
متن کاملTowards automatic analysis of gestures and body expressions in depression
Depression is a common mental disorder and one of the main causes of disease burden worldwide. Several studies in depression address the relation between non-verbal cues and different levels of depression. Manual coding of non-verbal cues is the common practice for running such studies, which is time consuming and non-objective. Recent research has looked into automatic detection of cues associ...
متن کاملAN-EUL method for automatic interpretation of potential field data in unexploded ordnances (UXO) detection
We have applied an automatic interpretation method of potential data called AN-EUL in unexploded ordnance (UXO) prospective which is indeed a combination of the analytic signal and the Euler deconvolution approaches. The method can be applied for both magnetic and gravity data as well for gradient surveys based upon the concept of the structural index (SI) of a potential anomaly which is relate...
