Introduction
Developed by IBM at Almaden Research centre.
Aims at giving computers highly developed abilities.
Enables computers and humans to work together more as partners.
Employs video camers.
Basic Principle
Human physiological traits are reliable resources for identification of emotions.
Measures GSR, heart rate, skin temperature.
Measures six basic emotions.
Data subjected to two analysis
1. Multidimensional scaling (MDS)
2. Discriminant function analysis.
Physiological measurements were correlated to emotions.
.
Recent developments
MAGIC Pointing
Eye tracker
Emotion Mouse
MAGIC POINTING
Pointing and selection were aided by gaze tracking.
Use gaze to redefine the position of cursor.
Two MAGIC pointing techniques are,
Liberal
Conservative
Advantages of magic pointing
Accurate
High speed
Reduce manual stress and fatigue.
Ease of use
Disadvantages
Eye gaze is not precise enough to operate
Movements of eyes are voluntarily controlled while at other times it is driven by external events.
Eye tracker
More compact and reliable
Illumination from an off-axis and on-axis source generates a dark pupil image and bright pupil image.
Working.
Advantages of eye tracker
Very Robust.
Able to detect pupils from wild field of view.
Range up to 5m from camera.
Can be used for even people with glasses.
Fast and low cost pupil detection technique.
EMOTION MOUSE
Emotions are important to the computing community.
A non-invasive way to obtain information about a user is through touch.
The computer determines the user's emotional state by a simple touch on the mouse.
Sensing of physiological attributes, related to emotions.
SIMPLE USER INTEREST TRACKER
SUITOR-The Simple User Interest Tracker.
Finds out the areas of interest of the user.
The attentive system
FUTURE DEVELOPMENTS
Security purposes.
ordinary household devices .
Eg : Working of television , refrigerators & ovens when we look at them.
