Mind Reading Computer Powerpoint outlines :
- Mind-Reading Computer
- Mind-Reading Computer Introduction
- What is Mind-Reading Computer
- and More
- Mind Reading: The set of abilities that allow a person to infer others’ mental states from nonverbal cues and observed behavior.
- Humans do it all the time!!
- Words are not the only means of conveying a message: facial expressions, hand gestures and voice modulations also play a vital role.
- A few examples
+ During a lecture expressions like “yawning” or “staring at the ceiling” indicate boredom.
+ Lovers : You say it best when you say nothing at all – Ronan Keating
- Mind reading is a very important part of a broader area of intelligence called social intelligence.
+ It gives you the ability to behave well in a social environment.
+ Empathize with others.
+ Choose correct words during a conversation.
- The absence of this ability in some humans is diagnosed as autism: such people find it difficult to operate in our complex social environment.
- Emotions and Facial Expressions
- Framework for Facial Expression Recognition
- Feature Extraction and Display Recognition
- Identifying emotions from the features and displays
- Training children diagnosed with Autism
- Fatigue detection
DIFFERENT ASPECTS OF MIND-READING
Deception v/s True Feelings
- People often have expressions that reflect emotions or mental states that are different than their true feelings or thoughts.
Non- verbal cues
- Facial Expressions
- Hand gestures
- Voice modulations
WISH-LIST FOR A FACIAL EXPRESSION RECOGNITION (FER) SYSTEM
- Range of mental states
- Should reliably classify a wide range of mental states.
- Fully automated
- None of the stages of an FER system should require manual intervention.
- Real Time
- Should respond to user’s emotions without any noticeable delay
- Continuous and asynchronous expressions
- Facial expressions are continuous and overlap each other.
- They may present mental states that are overlapping.
- User Independent
- Should not require retraining for a new user.
- Deals with occlusion of the face
- A portion of the face is missing such as when hand gestures occlude parts of the face.
- Supports talking
- Typically a person is talking and expressing his/her mental state ate the same time.
FACIAL DISPLAY IDENTIFICATION
- AN HMM for each facial display
- Observation variables: Action units
- Probability of occurrence of a display:- probability that the underlying action sequence is the output of corresponding Markov model.
- Forward or Backward algorithm
