The software capabilities of Emovision are very flexible. This allows us to adapt our software functions to companies or individuals personal requirements. Currently we offer products in two categories namely Visual and Emotion software. Within these categories we can offer numerous applications for our technology. Via a simple webcam Emovision can be used automatically analyze the facial expressions of persons in digital videos immediately. Based on the digital visual content six emotional categories are recognized; happy, surprise, sad, fear, anger and disgust.
The applications are based on the following state-of-the art inventions at the University of Amsterdam:
- Emotion Recognition Software
- Head pose recognition
- Voice recognition
- Eye tracking

The ubiquitous application of eye tracking is precluded by the requirement of dedicated and expensive hardware, such as infrared high definition cameras. Therefore, systems based solely on appearance (i.e. not involving active infrared illumination) are being proposed in literature. However, although these systems are able to successfully locate eyes, their accuracy is significantly lower than commercial eye tracking devices. Our aim is to perform very accurate eye center location and tracking, using a simple Web cam. By means of a novel relevance mechanism, the proposed method makes use of isophote properties to gain invariance to linear lighting changes (contrast and brightness), to achieve rotational invariance and to keep low computational costs.
