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.
