PERCEPTIVE COMPUTING
What is Perception
 The process of acquiring knowledge through the senses.
 Ability to feel, see and sense
What is Perceptive computer
 A computer with perceptual capabilities.
 Abilities to perceive, integrate, and interpret visual, auditory and touch information.
 Just like communicating with a human.
Why Perception
• To make the human – computer interaction more -
 Natural
 Easier
 Richer
• Computers would be much more powerful if they had even a small fraction of the perceptual ability of humans.
Perceptive Computing Projects
 Project BlueEyes
 Multimodal Interfaces
Project Blue Eyes
Features
 Uses non-obtrusive technology
 Extracts key information from the user’s cues and gestures.
 These cues are analyzed to determine the user’s physical, emotional or informational state.
 Attentive environments that are user and context aware.
Types of Blue Eyes projects
 Emotion mouses
 Suitor (Simple User Interest Tracker )
 MAGIC (Manual Acquisition with Gaze Initiated Control)
 Facial expression identification
Emotion Mouse
Features
 Simply by touching or using the mouse normally the computer will be able to determine the person’s emotional state
 The emotional state can then be related to the task the user is currently doing on the computer.
 Over time, a user model can be built up and the computer can adapt to the user to create a better working environment.
 The IR, GSA and GSR are inputs into a series of discriminate function analyses.
 The result is correlated to an emotional state.
 Hence, now an association has been established the user’s physiological state and the associated state.
